Abstract 

An integral assessment has been performed for the U.S. Nuclear Regulatory Commission 

by Pacific Northwest National Laboratory to quantify the predictive capabilities of 

FRAPCON-3, a steady-state fuel behavior code designed to analyze fuel behavior from 

beginning-of-life to rod-average burnup levels of 62 gigawatt-days per metric ton of 

uranium. FRAPCON-3 code calculations are shown to compare satisfactorily to a 

preselected set of experimental data with steady-state operating conditions. 

This document describes the assessment of FRAPCON-3.4a, which is the latest version of 

FRAPCON-3, released April 13, 2010.

Foreword 

The ability to accurately calculate the performance of light-water reactor fuel rods under 

high-burnup conditions is a major objective of the reactor safety research program being 

conducted by the U.S. Nuclear Regulatory Commission (NRC). To achieve this objective, 

the NRC has sponsored an extensive program of analytical computer code development. 

One product of this program is NRC’s FRAPCON code, which provides the ability to 

accurately calculate the high-burnup response of light-water reactor fuel rods. 

NRC also continues to sponsor both in-pile and out-of-pile experiments to benchmark and 

assess the analytical code capabilities. Over 100 new assessment cases were recently added 

to the integral assessment database, bringing the database total to 133 assessment cases. 

The new assessment cases use data from recent integral irradiation experiments and 

post-irradiation examination programs which provided valuable information on modern 

cladding materials and high-burnup fuel behavior. 

This report documents an integral assessment performed using the latest version of 

FRAPCON, FRAPCON 3.4, to demonstrate the code’s ability to accurately calculate the 

performance of newer fuel designs and operating conditions.

Executive Summary 

This document is Volume 2 of a two-volume series that describes the FRAPCON-3.4 code 

and its assessment. Volume 1 (Geelhood et al., 2010) describes the FRAPCON-3.4 code 

along with input instructions. Volume 2 (this document) describes the integral code 

assessment, done by comparing the code predictions for fuel temperatures, fission gas 

release (FGR), rod internal void volume, fuel swelling, cladding creep/growth, cladding 

corrosion/hydriding, and hoop strain to data from integral irradiation experiments and 

post-irradiation examination programs. 

The cases used for code assessment were selected based on the following criteria: 

 Well-characterized design and operational data were provided. 

 The reported results spanned ranges of interest for both design and operating 

parameters. 

Thus, the fuel rod cases were selected to represent both boiling-water reactor (BWR) and 

pressurized-water reactor (PWR) fuel types, with pellet-to-cladding gap sizes within, 

above, and below the normal range for power reactor rods. The fill gas is pure helium in 

most cases, but cases are included for which helium-xenon fill gas mixtures were used to 

assess the gap conductance model. The linear heat generation rates at beginning-of-life 

(BOL) range up to 60 kW/m (18 kW/ft), and during end-of-life (EOL) power ramps, they 

range up to 47 kW/m (14 kW/ft). The rod-average fuel burnups range up to 99 gigawattdays per metric ton of uranium (GWd/MTU), but only up to 76 GWd/MTU for powerramp cases. However, the code is only considered validated to rod-average burnup of 62 

GWd/MTU. The EOL FGR ranges from less than 1 percent to greater than 50 percent of 

the produced quantity. 

The primary code assessment database (used also for benchmarking the thermal and FGR 

models) consists of 133 well-characterized fuel rods. These include 45 test rods that 

experienced EOL power ramps (used for FGR and cladding hoop strain) and 88 “steadystate” cases including uranium dioxide (UO2), mixed oxide (MOX) fuel, and uraniagadolinia (UO2-Gd2O3) Halden rods used for fuel temperatures and UO2 and MOX rods 

used for FGR. 

Five rods from the primary set were used to assess FRAPCON-3.4 predictions of EOL void 

volume. The cases selected include full-length power reactor rods and shorter test reactor 

rods. A mix of test reactor and power reactor rods was also used to assess the fuel volume 

change due to densification and swelling. 

The FRAPCON-3.4 model for cladding waterside oxidation was evaluated against BWR 

Zircaloy-2 and PWR Zircaloy-4, ZIRLO, and M5 rod data. 

The FRAPCON-3.4 predictions of cladding hoop strain were assessed against 27 BWR and 

PWR rods that were power ramped in various test reactors. 

The following conclusions about FRAPCON-3.4 were made as a result of this assessment: 

Thermal: Comparisons were made for BOL UO2 temperature measurements and UO2. 

MOX, and UO2-Gd2O3 temperature measurements as a function of burnup. Overall, 
xvi 

FRAPCON-3.4 gave reasonable predictions of fuel centerline temperature for fuel rods 

with UO2, MOX, and UO2-Gd2O3 fuel (standard deviation of 5 percent relative). 

Fission Gas Release: Comparisons were made for the UO2 and MOX FGR measurements 

for rods with widely varying power levels and burnups. Overall, FRAPCON-3.4 gave 

reasonable predictions (within 5 percent FGR absolute) of fission gas release for fuel rods 

with UO2 and MOX fuel. 

Internal Void Volume: Comparisons were made to data from two commercial reactor and 

three test reactor fuel rods. The code predicted the two commercial rods well but 

overpredicted the BR-3 test rod data by approximately 15 percent (relative) on average. 

Cladding Corrosion: Comparisons were made to data from two commercial BWR rods 

with Zircaloy-2 cladding, two commercial PWR rods with Zircaloy-4 cladding, two 

commercial PWR rods with ZIRLO cladding, and one commercial PWR rod with M5 

cladding. The oxide corrosion predictions were very good and tend to bracket the data. 

Cladding Hoop Strain: The original hoop strain assessment cases that were available up to 

a burnup of around 45 GWd/MTU demonstrated that, on average, FRAPCON-3.4 slightly 

overpredicts cladding hoop strain by 0.1 percent strain. On average, above 45 GWd/MTU 

FRAPCON-3.4 underpredicts cladding permanent hoop strain by 0.3 percent. Despite this 

overprediction, FRAPCON-3.4 provides reasonable hoop strain predictions up to 

62 GWd/MTU.

1.0 Introduction 

This report is Volume 2 of a two-volume series that describes the FRAPCON-3.4 code and its 

assessment. Volume 1 (Geelhood et al., 2010) describes the FRAPCON-3.4 code. Volume 2 

(this document) describes the assessment of the integral performance of FRAPCON-3.4. 

This report provides the results of the assessment of the integral code predictions to measured 

data for fuel temperatures, fission gas release (FGR), internal void volume, cladding deformation, 

oxidation, and hydriding. The benchmark datasets are described in Section 2.0. Appendix A 

describes each set of benchmark data and gives the code input for each data comparison. The 

benchmark data are drawn from a wide range of burnup levels and operating conditions that are 

relevant to commercial operations. Experimental fuel rods with linear heat generation rates 

(LHGRs) at or near the maxima for commercial fuel operations were selected because the U.S. 

Nuclear Regulatory Commission (NRC) licenses fuel to the most limiting rod in the core. Not all 

the data selected are at limiting conditions. Some of the cases involve commercial fuel rods that 

operated at normal commercial operating conditions, which are significantly less than the limiting 

conditions. Also, it is noted that most of the thermal and FGR benchmark cases are drawn from 

experimental programs that involved numerous fuel rods, of which only a few were selected as 

benchmark cases. This was either because the rods in a given group were all irradiated under 

similar conditions and had similar FGR or because only rods with design parameters and 

operating conditions similar to current commercial practice were selected. 

The integral code assessments include comparison to fuel temperature data in Section 3.0 and 

FGR data in Section 4.0. Comparisons of code predictions to internal void volume, cladding 

corrosion and hydriding, and hoop strain data are given in Sections 5.0, 6.0, and 7.0 respectively. 

A summary and conclusions are found in Section 8.0.
2.1 

2.0 Assessment Data Description 

A total of 133 benchmark cases (fuel rods) that have post-irradiation examination (PIE) were 

selected for the integral assessment of the FRAPCON-3.4 code. These include 88 fuel rods with 

steady-state power operation covering a wide range of burnup and 45 fuel rods with steady-state 

irradiations followed by an end-of-life (EOL) power ramp. The purpose of the code assessment 

was to assess the code against a limited set of well-qualified data that span the range of limiting 

operational conditions for commercial light-water reactors (LWRs) to verify that the code 

adequately predicts the integral data. The integral data of interest were fuel temperatures, FGR, 

corrosion, void volumes, and cladding deformation. The cases in this relatively limited group 

were selected using criteria regarding the completeness and the quality of the rod performance 

data, as follows: 

 The cases should all provide pre-irradiation characterization with well-qualified fuel rod 

powers, and some data should include PIE data of interest (e.g., FGR, cladding dimensional 

changes). 

 Cases for temperature assessment should provide well-qualified fuel centerline temperature 

data as a function of time or burnup to verify fuel temperature predictions. 

 Cases ranging from low to high fuel burnup, as well as low to high (limiting) LHGR, should 

be provided to cover the operating ranges for LWR operation for each fuel performance issue 

of interest (e.g., fuel temperature, FGR, deformation). 

 Cases should provide cladding oxidation, hydriding, and deformation under prototypic 

pressurized-water reactor (PWR) and boiling-water reactor (BWR) conditions. 

 Cases should demonstrate the effects (FGR and cladding deformation) of normal operational 

transients, and overpower transients including anticipated operational occurrences (AOOs) at 

low and high burnup. 

The selected cases fulfill the above criteria, and they provide a mix of well-qualified test reactor 

data and less qualified (fuel rod power uncertainties are generally greater) commercial powerreactor rod data. 

Figures 2.1, 2.2, and 2.3 show the rod-average LHGRs as a function of rod-average burnup for 

the rods in the temperature, FGR, and hoop strain assessment databases, respectively. These 

figures demonstrate the range of burnup and LHGRs to which the FRAPCON-3.4 predictions 

have been qualified for each of these integral code predictions. For the code prediction of 

cladding corrosion, the predictions are a function of time, power level, and coolant temperature. 

FRAPCON-3.4 has been qualified to predict cladding corrosion of Zircaloy-2 under BWR 

conditions beyond a rod-average burnup of 62 gigawatt-days per metric ton of uranium 

(GWd/MTU), and Zircaloy-4, ZIRLO, and M5 under PWR conditions beyond a rod-average 

burnup of 70 GWd/MTU for 12 foot cores. The outlet temperature of 14 foot reactor cores may 

be higher than has been assessed for FRAPCON-3.4, and the corrosion predictions at these 

temperatures have not been assessed.

3.0 Thermal Behavior Assessment 

Thermal predictions are important for calculating initial fuel stored energy, which is used as input 

to loss-of-coolant accident (LOCA) analyses. The fuel temperatures are also used to calculate 

FGRs and EOL rod pressures and to verify no fuel melting. In general, PWR LOCA and fuel 

melting analyses are calculated with FRAPCON-3.4 to be more limiting at burnups between 25 

and 35 GWd/MTU, while the same analyses for BWRs are generally more limiting at burnups 

between 15 and 25 GWd/MTU. 

Comparisons of predicted and measured fuel center temperatures from instrumented Halden 

reactor test assemblies have been used to evaluate the code’s ability to predict BOL temperatures 

and through-life temperature histories (i.e., rod power vs. burnup). The BOL and through-life 

temperature comparisons are separated because they have different biases and uncertainties 

(based on standard deviation) in the code thermal predictions. The through-life temperature 

history comparisons will be used to bound the uncertainties on PWR and BWR LOCA 

initialization and fuel melting analyses. The BOL temperature database includes not only rods 

with helium-filled gaps, but also rods with xenon and xenon-helium filled gaps and rods with 

pellet/cladding gap sizes both larger and smaller than nominal. These variations in gap size and 

fill gas indicate that the code can properly account for the thermal resistance across the fuel 

cladding gap as a function of gap size and gas composition and is not just tuned to provide good 

results for typical LWR conditions. 

The comparisons of measured and predicted through-life fuel center temperature histories were 

done with two goals in mind. The first was to determine if the code properly accounts for the fuel 

thermal conductivity degradation with burnup. The second goal was to determine if the code 

properly predicts the effect of thermal feedback on fuel temperature caused by gas release and 

consequent contamination of the initial helium fill gas with lower-conductivity fission gas. 

The BOL and through-life code-data comparisons are discussed separately in the following 

sections.

3.1 BOL Fuel Center Temperature Predictions 

The BOL fuel centerline temperature predictions are assessed against centerline temperature 

measurements taken during the first ramp to power. This power ramp occurs during the first 1 to 

2 days of operation. Because of this, the initial fuel rod dimensions apply and there is no time for 

phenomena such as FGR, fuel densification and swelling, cladding creep, or cladding corrosion. 

3.1.1 UO2 BOL Center Temperature Predictions 

FRAPCON-3.4 was assessed against BOL temperature measurements taken during the first ramp 

to power. Thirteen rods are used to assess the performance of FRAPCON-3 at BOL: IFA-432 

rod 1, IFA-432 rod 2, IFA-432 rod 3, IFA-513 rod 1, IFA-513 rod 6, IFA-681 rod 1, IFA-633 rod 

1, IFA-633 rod 3, IFA-633 rod 5, IFA-677.1 rod 2, IFA-677.1 rod 3, IFA-677.1 rod 4, and IFA677.1 rod 6. Figure 3.1 shows the predicted vs. measured temperature for the BOL ramp up to 

power for the 13 assessment cases. This figure shows that FRAPCON-3.4 predicts these 

centerline temperatures within a standard error of 7.0 percent of the measured centerline 

temperature with an average deviation of -5.5 percent. For the IFA-513 rod 6 case and all the 
3.2 

IFA-677.1 cases, FRAPCON-3.4 tends to underpredict the centerline temperature, but for all 

other rods, FRAPCON 3.4 predicts centerline temperature within a standard error of 4.8 percent 

and average deviation of -2.8 percent. A standard error of 4.5 percent corresponds to around a 

±50K uncertainty on temperature predictions and is reasonable given the uncertainty in the 

thermocouple data and the calculated rod power. For rods with greater standard error, there may 

have been a bias in the reported power or temperature, or FRAPCON-3.4 may not be properly 

modeling some aspect of these rods’ behavior.

3.2 Assessment of Temperature Predictions as a Function of Burnup 

3.2.1 UO2 Center Temperature Predictions as a Function of Burnup 

The assessment of FRAPCON-3.4 UO2 temperature predictions was performed using the same 

cases that were used for the BOL assessment, with the following differences. 

1. IFA-432 rod 2 has been removed as an assessment of FRAPCON-3 as a function of burnup, 

as the test is not prototypic of current fuel designs due to its large gap, and a small 

overprediction in FGR can result in a large temperature overprediction. 

2. IFA-633 rods 1, 3, and 5 and IFA-677.1 rods 3, 4, and 6 originally only had BOL temperature 

reported and only recently had measured temperature as a function of burnup reported. 

Therefore, these rods are not included in this assessment. 

3. IFA-562 rod 18, IFA-597 rod 8, IFA-515.10 rods A1 and B1, IFA-681 rod 5, and IFA-558 

rod 6 have been added in addition to the BOL assessment cases. 
3.3 

The following figures show measured and predicted fuel centerline temperatures from rods with 

centerline temperature measurements. Individual rod predictions may demonstrate a systematic 

error (bias) that may be due to thermocouple decalibration or a systematic error in the power 

history or axial power shape (power at thermocouple location) provided due to decalibration in or 

with the neutron detectors. However, when all the comparisons are examined, it is found that 

there is no overall systematic error (bias) in the prediction of UO2 fuel temperature throughout 

life, as can be seen in Figure 3.2. For all the cases, a standard error of 4.7 percent on the 

centerline temperature was calculated. These data are also shown in terms of relative bias in 

Figure 3.3 as a function of burnup. There appears to be no systematic bias in the predictions with 

increasing burnup.

Figure 3.5 shows the measured and predicted centerline temperature for IFA-432r3. This figure 

contains data from the lower thermocouple. This rod also contained an upper thermocouple, but 

it failed after 550 days. The comparisons to the upper thermocouple data are similar to the lower 

thermocouple. This figure shows excellent agreement between the FRAPCON-3.4 predictions 

and the data at BOL, and an overprediction of about 100K at EOL. This overprediction may be 

due to FRAPCON-3.3 overpredicting the gas release, leading to higher predicted temperatures. 

As noted earlier, overprediction of gas release leads to lower gap conductivity and results in 

higher fuel temperature predictions. It should also be noted that some of the helium fill and 

fission gases were found to have leaked out of these IFA-432 rods based on rod puncture data 

(i.e., the leak was theorized to have occurred around the thermocouple penetrations through the 

end caps).

underprediction has been reduced to a more reasonable level of 75K or less. This rod (Figure

This section demonstrates that FRAPCON-3.4 continues to provide a best-estimate prediction of 

centerline temperature for UO2 rods to within a standard error of 4.7 percent for recent 

experimental data (see Figure 3.2). The largest deviation was for IFA-677 rod 2, which shows a 

150K underprediction at BOL that decreases to less than 75K by 300 days. All the IFA-677 rods 

were also underpredicted in the BOL temperature section, perhaps demonstrating a bias in this 

data, particularly compared with rods of similar power, burnup levels, and gap size that 

demonstrate better agreement with the code. 

It is noted that in some of these cases the temperatures are predicted well throughout life, while in 

other cases there is a deviation with time, and in others there is a consistent bias throughout life. 

The cases with a deviation with time are likely due to a small difference in FGR predictions that 

affect the calculated centerline temperature or a drift in neutron detectors with time that affects 

measured rod powers. In some cases, the neutron detectors are recalibrated between reactor 

cycles such that at a given burnup or time the predicted and measured temperatures begin to agree 

better or deviate. The cases with a constant bias throughout life are likely due to a bias in the 

reported rod power or measured temperature. 

3.2.2 MOX Center Temperature Predictions as a Function of Burnup 

FRAPCON-3.3 predictions have been benchmarked against centerline temperatures taken from 

eight Halden tests with instrumented fuel assemblies containing 15 MOX fuel rods. The results 

of these comparisons are provided in this section. 

The following figures show measured and predicted fuel centerline temperatures from rods with 

centerline temperature measurements. Individual rod predictions may demonstrate a systematic 

error (bias) that may be due to thermocouple decalibration or a systematic error in the power 

history or axial power shape (power at thermocouple location) provided due to decalibration in or 

with the neutron detectors. However, when all the comparisons are examined, no overall 

systematic error (bias) is found in the prediction of MOX fuel temperature throughout life, as can 

be seen in Figure 3.16. For all the cases, a standard error of 4.7 percent on the centerline 

temperature was calculated. These data are also shown in terms of relative bias in Figure 3.17 as 

a function of burnup. There appears to be no systematic bias in the predictions with increasing 

burnup.

This section demonstrates that FRAPCON-3.4 continues to provide a best-estimate prediction of 

centerline temperature for MOX rods to within a standard error of 4.7 percent. The largest 

deviation was for 633-1 rod 6, which shows up to a 150K overprediction at higher burnup. This 

may be due to overpredicting the FGR for this rod. 

3.2.3 UO2-Gd2O3 Center Temperature Predictions as a Function of Burnup 

The adjustment for gadolinia in the thermal conductivity model has been assessed against 

centerline temperature predictions from three instrumented fuel assemblies irradiated at the 

Halden reactor. The results of these comparisons are provided in this section. 

The following figures show measured and predicted fuel centerline temperatures from rods with 

centerline temperature measurements. Individual rod predictions may demonstrate a systematic 

error (bias) that may be due to thermocouple decalibration or a systematic error in the power 

history or axial power shape (power at thermocouple location) provided due to decalibration in or 

with the neutron detectors with time. However, when all the comparisons are examined, no 

overall systematic error (bias) is found in the prediction of UO2-Gd2O3 temperature throughout 

life, as can be seen in Figure 3.33. For all the cases, a standard error of 4.9 percent on the 

centerline temperature was calculated. These data are also shown in terms of relative bias in 

Figure 3.34 as a function of burnup. It can be seen that there appears to be no systematic bias in 

the predictions with increasing burnup.

Figures 3.35 and 3.36 show the measured and predicted centerline temperature for IFA-515.10. 

Rods A1 and B1 are UO2 rods and rods A2 and B2 are UO2-Gd2O3 rods with depleted gadolinium 

(Gd) that did not contain any 155Gd or 157Gd. There are two factors that influence the centerline 

temperature for UO2-Gd2O3 rods relative to UO2 rods: 1) degradation in thermal conductivity due 

to Gd addition and 2) radial power profile due to the neutron absorption of 155Gd and 157Gd. 

These rods were meant to show the difference only due to the thermal conductivity degradation 

from gadolinia (Gd2O3), not due to the difference in radial power profile. A modified version of 

FRAPCON-3.4 that uses the UO2 radial power profile model (TUBRNP) for UO2-Gd2O3 rods 

(A2 and B2) was used to perform these calculations. These figures show that FRAPCON-3.4 

predicts the centerline temperatures for UO2-Gd2O3 rods as well as for UO2 rods. In these figures, 

the vertical line denotes where the thermocouple failed. Although data was reported after this 

point, it is not valid.

and the data from this thermocouple is shown in Figure 3.37. Rod 4 contains solid pellets, and

measurement of temperature (no thermocouple), there is more uncertainty in the data from rod 4 

because this is estimated by Halden using the rod 2 temperature data and correcting for no 

thermocouple hole. In addition, during the first rise to power, as the Gd is burning out, there is a 

high level of uncertainty on the reported rod power. Because of this, FRAPCON-3.4 may not 
3.27 

predict the centerline temperature well during this period. These figures show excellent 

agreement between the FRAPCON-3.4 predictions and the data for rod 2 and reasonable 

agreement for rod 4, which has greater uncertainty.

Figures 3.39 through 3.44 show the measured and predicted centerline temperature for IFA-681 

rods 1, 2, and 3 with centerline thermocouples and rods 4, 5, and 6 with hollow pellets and 

expansion thermometers. Rods 1 and 5 are UO2 rods. Rods 2 and 4 contain standard Gd with 

2 wt% Gd2O3. Rods 3 and 6 contain standard Gd with 8 wt% Gd2O3. Since these rods contain 

standard Gd, the release version of FRAPCON-3.4 could be used. During the first rise to power, 

as the Gd is burning out, there is a high level of uncertainty on the reported rod power. Because 

of this, FRAPCON-3.4 may not predict the centerline temperature well during this period. This 

does not significantly affect future predictions because power levels while the Gd is burning out 

are low and will not cause significant FGR that will affect future temperature predictions. 

These figures show excellent agreement between the FRAPCON-3.4 predictions and the data for 

rods 1 and 2 (Figures 3.39 and 3.40). For rod 3 (Figure 3.41), the FRAPCON-3.4 predictions are 

in excellent agreement with the data for the first 200 days. After this, FRAPCON-3.4 

overpredicts the data by up to 100K. The reason for this is not clear, as both the power and the 

FRAPCON-3.4 temperature prediction increase during this time period, but the measured 

temperature does not increase with increasing power. For the hollow pellet rods, the UO2 and 

2 wt% Gd2O3 rods (IFA-681 rods 5 and 4 in Figures 3.43 and 3.42, respectively) are uniformly 

underpredicted by about 50K while the 8 wt% Gd2O3 rod (IFA-681 rod 6) is predicted well 

(Figure 3.44). These differences are well within the uncertainty of temperature measurement and 

power levels.

4.0 Fission Gas Release Assessment 

4.1 Assessment of Steady-State FGR Predictions 

An accurate prediction of FGR is important for two reasons: 1) it has a significant impact on the 

prediction of gap conductance and, therefore, fuel temperatures (e.g., as demonstrated in Section 

3.0, an overprediction of FGR can result in an overprediction of fuel temperatures, and the 

converse is also true), and 2) it is necessary for the calculation of rod internal pressures that affect 

LOCA analyses and EOL rod pressures. In many cases, for current operating plants, the limits on 

and analyses of EOL rod pressures determine the LHGR limits for commercial fuel at burnups 

greater than 30 GWd/MTU. In addition, the NRC requires that these EOL rod pressure analyses 

include bounding normal operation transients (e.g., xenon transients lasting several hours) and 

AOOs (e.g., overpower transients lasting several minutes to hours). Therefore, the accurate 

prediction of transient FGR under conditions of power increases above steady-state operation is 

important for licensing analyses. 

The code’s ability to predict FGR in UO2 fuel has been assessed based on comparisons to FGR 

data from 23 UO2 fuel rods with power histories that are relatively steady-state through the rods’ 

irradiation life and 19 UO2 rods with power bumping (increase in rod power) at EOL to simulate 

an overpower AOO or normal operational transients. The code’s ability to predict FGR in MOX 

fuel has been assessed based on comparisons to FGR data from 34 MOX fuel rods with power 

histories that are relatively steady-state through the rods’ irradiation life and 8 MOX rods with 

power bumping (increase in rod power) at EOL to simulate an overpower AOO or normal 

operational transients. The fuel rods with greater than 5 percent FGR were selected because the 

limiting rods in terms of EOL rod pressure in today’s plants (particularly for power uprated 

plants) have releases above 10 percent FGR. 

No fuel rods with UO2-Gd2O3 fuel were available for assessment of the code’s ability to predict 

FGR in UO2-Gd2O3 fuel. However, it has been observed that the measured FGR from UO2-

Gd2O3 rods is similar to the FGR from UO2 rods with the same power history (Hirai et al., 1995). 

FRAPCON-3.4 will predict slightly higher FGR for a UO2-Gd2O3 rod than for an identical UO2

rod due to the lower fuel thermal conductivity in the UO2-Gd2O3. Based on the above 

observation, this modeling assumption is conservative. 

The assessment in this section has used the default FGR model in the MASSIH subroutine in the 

code that is based on a modified release model proposed by Forsberg and Massih (1985). This 

release model is described in Volume 1 of this report (Geelhood et al., 2010). The other FGR 

models in FRAPCON-3.4 (i.e., ANS-5.4 and FRAPFGR) provide reasonable predictions of FGR 

for fuel rods with steady-state power histories, but on average underpredicted FGR for fuel rods 

with power bumping for a few hours duration. 

The following discussions are divided into comparisons of the code predictions to steady-state 

FGR data and to power bumping (transient) FGR data

4.1.1 UO2 Steady-State FGR Predictions 

Figure 4.1 shows the predicted FGR as a function of measured FGR for the steady-state UO2 rods. 

Figure 4.2 shows the predicted minus measured FGR as a function of burnup for the steady-state 

UO2 rods. The steady-state UO2 cases with measured and predicted FGRs are shown in Table 4.1. 
4.2 

The standard deviation for the steady-state predictions is 2.6 percent absolute FGR up to 

70 GWd/MTU. These figures demonstrate that FRAPCON-3.4 provides a best-estimate 

calculation of fission gas over a wide range of gas release levels up to a rod-average burnup of 

62 GWd/MTU. There are a few cases at higher burnup, but these cases indicated that 

FRAPCON-3.4 may begin to underpredict FGR at burnup levels beyond 62 GWd/MTU (Figure 

4.2).

4.1.2 MOX Steady-State FGR Predictions 

Figure 4.3 shows the predicted FGR as a function of measured FGR for the steady-state MOX 

rods. Figure 4.4 shows the predicted minus measured FGR as a function of burnup for the 

steady-state MOX rods. The steady-state MOX cases with measured and predicted FGRs are 

shown in Table 4.2. The standard deviation for the steady-state predictions is 6.7 percent FGR. 

It is noted that some of these MOX rods are from the Advanced Test Reactor (ATR) at Idaho 

National Laboratory and are subject to large radial flux profiles. Because of this, it is difficult to 

estimate the rod-average power. If the ATR rods are removed from the calculation of standard 

deviation, a standard deviation of 4.5 percent absolute FGR is calculated. These figures 

demonstrate that FRAPCON-3.4 provides a best-estimate calculation of fission gas over a wide 

range of gas release levels up to a rod-average burnup of 62 GWd/MTU. There are a few cases at 

higher burnup, but these cases indicated that FRAPCON-3.4 may begin to underpredict FGR at 

burnup levels beyond 62 GWd/MTU (Figure 4.4).

4.2 Assessment of Power-Ramped FGR Predictions 

4.2.1 UO2 Power-Ramped FGR Predictions 

Figure 4.5 shows the predicted FGR as a function of measured FGR for the power-ramped UO2

rods. Figure 4.6 shows the predicted minus measured FGR as a function of burnup for the powerramped UO2 rods. The power-ramped UO2 cases with measured and predicted FGRs are shown 

in Table 4.3. These comparisons show that the code provides a good prediction of the transient 

FGR data except for the two High Burnup Effects Program (HBEP) rods, D200 and D226, which 

are underpredicted by 21 percent and 12 percent release, respectively. The fuel in both of these 

rods is considered atypical of today’s fuel used in commercial rods because it is prone to 

significant fuel densification (> 2.5 percent theoretical density (TD)), unlike the less densification 

prone (stable) fuel (< 1.5 percent TD) of current fuel designs. In addition, there is evidence that 
4.6 

fuel with significant densification releases more fission gas than current stable fuel. The standard 

deviation for the power-ramped predictions without D200 and D226 is 5.1 percent absolute FGR. 

These figures demonstrate that FRAPCON-3.4 provides a best-estimate calculation of fission gas 

over a wide range of gas release levels up to a rod-average burnup of 62 GWd/MTU. 

Normal operational transients typically last between 4 and 12 hours, while AOO power transients 

last less than 30 minutes. Because both of these types of transients can lead to FGR, the NRC 

requires that both be included in the rod internal pressure analyses to demonstrate that they meet 

the no cladding liftoff criterion. In general, the short hold time AOO transient results in the lower 

FGR. However, the burst release typically seen in transients on the order of less than 30 minutes 

appears to be increasing with increasing burnups, particularly above 62 GWd/MTU, such that the 

code may be underpredicting release for short time period transients at high burnup. Therefore, 

future code verification will examine FGR data with power ramps of short duration.

Figure 4.7 shows the predicted FGR as a function of measured FGR for the power-ramped MOX 

rods. Figure 4.8 shows the predicted minus measured FGR as a function of burnup for the powerramped MOX rods. The power-ramped MOX cases with measured and predicted FGRs are 

shown in Table 4.4. The standard deviation for the steady-state predictions is 13.4 percent 

absolute FGR and the average deviation (bias) is 11.8 percent absolute FGR. These figures 
4.8 

demonstrate that FRAPCON-3.4 tends to overpredict the gas release measurement for powerramped rods. However, it is noted that a limited number of power-ramped rods from only one 

experimental program are represented here. In addition, it is conservative to overpredict FGR 

during a power ramp.

5.0 Internal Rod Void Volume Assessment 

5.1 Fuel Rod Void Volume 

An accurate prediction of the internal void volume of a fuel rod is important in the calculation of 

the internal rod pressures along with the FGR prediction. The change in the fuel rod void volume 

with burnup is primarily due to the combined effects of cladding creep, fuel swelling, and axial 

cladding growth. Five well-characterized fuel rods were selected to assess the capability of 

FRAPCON-3 to accurately calculate fuel rod void volumes for high burnup. The cases selected 

include two full-length rods (rod TSQ002 from ANO-2 and rod 15309 from Oconee) and three 

short (44 inches long) rods (36-I-8, 111-I-5, and 24-I-6) that were irradiated in the BR-3 reactor. 

The set includes only PWR fuel rods with standard Zircaloy-4. The burnup levels achieved on 

these rods range from 48.6 to 61.5 GWd/MTU. 

Table 5.1 presents the measured and FRAPCON-3 calculated void volume at both BOL and EOL 

for the five fuel rods. The calculations were made at 25°C (77°F) and atmospheric pressure, 

which should be reasonably close to the temperature at which the data were collected. A range of 

values for void volume is provided for Oconee rod 15309 because this is the range of void 

volumes measured from 16 sibling fuel rods from the same assembly—including the 

representative rod 15309. All sixteen rods have very similar EOL burnups and similar power 

histories. Therefore, the void volume range includes representative uncertainty in the fabricated 

void volumes, measured rod power histories, and burnup. 

The FRAPCON-3.4 code does a good job of calculating the integral fuel rod void volumes, 

particularly for the commercial reactor rods where as-fabricated void volumes were provided. 

The three BR-3 test rods are overpredicted by 15 percent on average, but this may be due to an 

overestimation in the as-fabricated void volumes.

6.0 Cladding Corrosion Assessment 

Seven well-characterized fuel rods were selected to demonstrate the capability of FRAPCON-3 to 

accurately calculate fuel rod waterside oxidation and hydrogen concentration for high burnup. 

The cases selected include seven full-length rods (rod TSQ002 from ANO-2; rod 15309 from 

Oconee; rod A1 from Monticello bundle MTB99; rod H8/36-6 from TVO-1; and rods A06, A12, 

and N05 from Vandellos II). The set includes both PWR and BWR fuel rods that are standard 

Zircaloy-4, ZIRLO, or M5 in PWRs and Zircaloy-2 in BWRs. (These are the cladding alloys 

currently modeled in FRAPCON-3.4.) The rod-average burnup levels achieved on these rods 

range from 45 to 53 GWd/MTU. 

Table 6.1 shows the measured and FRAPCON-3.4 calculated peak oxide layer thickness for the 

two selected high-burnup BWR rods. The measured and predicted corrosion layer thicknesses as 

a function of axial position along the rod are shown for the two PWR rods in Figures 6.1 and 6.2. 

The comparisons indicate that FRAPCON-3.4 can satisfactorily predict peak and axial variation 

in cladding waterside oxidation. 

FRAPCON-3 calculated peak oxide layer thickness and peak hydrogen concentrations are 

bracketed by the choice of crud layer thickness for the PWR rods and are in good agreement for 

the two BWR rods. The purpose of these code-data comparisons is to demonstrate similar 

predictions as with standalone versions of the corrosion/hydriding models. The BWR peak 

corrosion values are fairly well matched by the FRAPCON-3 predictions, and these predictions 

are not as sensitive to the crud layer input because of the relatively lower heat fluxes and lower 

operating temperatures. 

The conclusion is that the modeling of waterside oxidation is sufficient in FRAPCON-3.4 for 

best-estimate analyses. Using integral effect and separate effect data the following standard 

deviations for each alloy has been calculated or estimated 

 Zircaloy-2: =7.6 m 

 Zircaloy-4: =15.3 m 

 ZIRLO: =15 m 

 M5: =5 m 

6.1 BWR Cladding Corrosion 

The only alloy currently used in the United States for BWR conditions is Zircaloy-2. The 

following assessment shows the FRAPCON-3.4 predictions of cladding corrosion for two 

commercial rods with Zircaloy-2.

7.0 Cladding Hoop Strain during Power Ramps 

7.1 Assessment Cases 

The ability of FRAPCON-3.4 to predict permanent hoop strain during power ramps was 

originally assessed against a database consisting of 17 power-ramped rods at burnup levels 

between 18 and 45 GWd/MTU to ramp terminal levels between 30 and 44 kW/m. All of these 

rods were held at the ramp terminal level for a significant period of time (> 4 hours). The 

measured and predicted rod-average permanent hoop strains are shown in Figure 7.1. This figure 

shows that in general FRAPCON-3.4 overpredicts the measured hoop strain. It was found that 

FRAPCON-3.4 overpredicts cladding permanent strain by 0.1 percent (on average) with 

significant variation between predicted and measured.

Permanent Hoop Strain Incrament, %

Mid Pellet FRAPCON-3.4

Figure 7.1 Measured and predicted rod-average permanent hoop strain for original 

assessment database 

This overprediction is consistent with the fact that FRAPCON-3.4 uses a rigid pellet assumption. 

This means that the pellet is assumed to be significantly stronger than the cladding such that it 

will not deform, other than the code-assumed accommodation of 50 percent of the relocation, 

when it comes in contact with the cladding. 

FRAPCON-3.4 was compared to a more recent database of power-ramped rods that were ramped 

under the Studsvik Cladding Integrity Project (SCIP). This database consists of 10 power-ramped 

rods at burnup levels between 40 and 76 GWd/MTU to ramp terminal levels between 38 and 

52 kW/m. Some of these rods were held at the ramp terminal level for a significant period of 

time (> 30 minutes), while other rods were held for a very short period of time (1 to 30 seconds). 

The measured and predicted peak node permanent hoop strains are shown in Figure 7.2. For 

these rods, FRAPCON-3.4 underpredicts cladding permanent strain by 0.3 percent on average.

Figure 7.2 Measured and predicted peak node permanent hoop strain for SCIP ramp 

tests. Tests are not explicitly labled to protect the sensitivity of this 

information. 

To determine if the overpredictions noted in the SCIP ramp tests are due to ramp terminal level, 

hold time, or burnup, the predicted minus measured permanent hoop strain for all the assessment 

cases were plotted as a function of ramp terminal level and burnup, with the short hold time SCIP 

ramps and the long hold time SCIP ramps separated. 

Normal operational transients typically last 4 to 12 hours, while AOO power transients last less 

than 30 minutes but have a higher terminal power level than normal transients. Because both of 

these types of transients need to demonstrate that they meet the NRC 1percent strain (elastic + 

plastic) criterion, the code needs to be evaluated for both short and long hold time transients. In 

general, the short hold time AOO transient is the most limiting due to its higher terminal powers, 

although pellet/cladding-interaction (PCI) failures have been significant in recent years for BWR 

fuel designs. It should be noted that PCI failures are due to stress corrosion cracking (SCC) and 

are known to exist below the NRC 1 percent strain criterion. It is further noted that FRAPCON3.4 currently does not have a failure criterion for these very low stress/strain PCI failures. 

7.2 Comparisons vs. Ramp Terminal Level 

Figure 7.3 shows the predicted minus measured permanent hoop strain for all the assessment 

cases as a function of ramp terminal power level. There does not appear to be any bias in the 

predictions with increase ramp terminal power level. However, it does appear that the SCIP 

ramps with long hold times are underpredicted more than the SCIP ramps with short hold times.

Figure 7.4 shows the predicted minus measured permanent hoop strain for all the assessment 

cases as a function of burnup. For burnup levels greater than 45 to 55 GWd/MTU, it appears that 

FRAPCON-3.4 begins to underpredict permanent hoop strain with increasing burnup. In addition, 

it appears that this underprediction is more severe for the long hold time cases.

The FRAPCON-3.4 predictions for the short hold time data appear to be predicted well up to 

62 GWd/MTU. The adequacy of the FRAPCON-3.4 predictions for long hold times between 

45 to 52 GWd/MTU is less certain due to lack of data. There is a definite trend of 

underprediction with burnup above 60 GWd/MTU for power ramps with long hold times. The 

code should be modified to address this apparent underprediction at high burnup. 
8.1 

8.0 Conclusions 

The FRAPCON-3.4 steady-state fuel performance code has been assessed against a set of preselected data from 133 well-characterized fuel rods. The data used for the assessment consisted 

of measurements of thermal (fuel temperature), FGR, rod internal void volume, and cladding 

corrosion. The fuel rods represent a range of design parameters, including different fuel rod 

diameters, lengths, gap sizes, and fill-gas compositions and a wide range of operating conditions 

with peak LHGRs varying from 8 to 18 kW/ft, rod-average burnups from 0 to 99 GWd/MTU, and 

FGRs ranging from less than 1 percent to greater than 50 percent. The estimates of code thermal 

and FGR predictive error are based on code comparisons to both the benchmark and independent 

data sets. 

Thermal: Comparisons were made for BOL UO2 temperature measurements and UO2, MOX, and 

UO2-Gd2O3 temperature measurements as a function of burnup. For the UO2 BOL temperature 

measurements, the FRAPCON-3.4 predictions were within a standard error of 7.0 percent of 

measured values and a biased underprediction of 5.5 percent. The bias and standard error become 

small (-2.8 percent and 4.8 percent, respectively) if the IFA-513 rod 6 with helium/xenon gas and 

all the IFA-677 rods are eliminated. For the UO2 temperature measurements as a function of 

burnup, the FRAPCON-3.4 predictions were within a standard error of 4.7 percent of the 

measured values. Only IFA-677 rod 2 was underpredicted by up to 150K at BOL, similar to what 

was seen in the BOL assessments for the IFA-677 rods. Typically, a standard error of 3 to 4 

percent is the uncertainty in temperature due to power level uncertainty. For the MOX 

temperature measurements as a function of burnup, the FRAPCON-3.4 predictions were within a 

standard error of 4.7 percent of the measured values and much closer in most cases. Only IFA633.1 was overpredicted by up to 150K at EOL. This overprediction may be due to the code 

overpredicting the FGR leading to higher fuel temperatures. 

 

For the UO2-Gd2O3 temperature measurements as a function of burnup, the FRAPCON-3.4 

predictions were within a standard error of 4.9 percent of the measured values and much closer in 

most cases. 

Overall, FRAPCON-3.4 gives reasonable predictions (standard error of 5 percent) of fuel 

centerline temperature for fuel rods with UO2, MOX, and UO2-Gd2O3 fuel. 

Fission Gas Release: Comparisons were made for the UO2 and MOX FGR measurements for 

rods with widely varying power levels and burnups. No assessment cases were available to 

assess the FGR predictions for UO2-Gd2O3 fuel, but it was concluded that the FGR from these 

rods should be conservatively bounded with the UO2 FGR model. The UO2 FGR model was 

assessed for steady-state conditions and power-ramped rods. For the UO2 cases, a standard 

deviation of 2.6 percent FGR (absolute) was calculated for the steady-state rods and a standard 

deviation of 5.1 percent FGR (absolute) was calculated for the power-ramped rods when two rods 

with non-prototypical pellets were removed. These standard deviations are considered reasonable. 

Although there is little data above 62 GWd/MTU, it appears that FRAPCON-3.4 may 

underpredict UO2 fuel above this burnup level. 

For the MOX cases, a standard deviation of 4.5 percent FGR (absolute) was calculated for the 

steady-state rods when the ATR rods with large power uncertainty were removed, and a standard 

deviation of 13.4 percent FGR (absolute) was calculated for the limited number of power-ramped 

rods that all came from one experimental program. The steady-state standard deviation is 
8.2 

considered reasonable. The power-ramped rods were all overpredicted, which is conservative for 

rod internal pressure and temperature calculations. However, a larger database of MOX powerramped cases is needed to further assess if this overprediction is due to a code deficiency. 

Although there is little data above 62 GWd/MTU, it appears that FRAPCON-3.4 may 

underpredict MOX fuel above this burnup level. 

FGR data was not available for comparison for UO2-Gd2O3 fuel rods. 

Overall, FRAPCON-3.4 gives reasonable predictions (within 5 percent FGR absolute) of fuel 

centerline temperature for fuel rods with UO2 and MOX fuel. 

Internal Void Volume: Comparisons were made to data from four commercial reactor and three 

test reactor fuel rods. The code predicted the two commercial rods well but overpredicted the 

BR-3 test rod data by approximately 15 percent (relative) on average. 

Cladding Corrosion: Comparisons were made to data from two commercial BWR rods with 

Zircaloy-2 cladding, two commercial PWR rods with Zircaloy-4 cladding, two commercial PWR 

rods with ZIRLO cladding, and one commercial PWR rod with M5 cladding. The oxide 

corrosion predictions were very good and tend to bracket the data. Using integral effect and 

separate effect data, the following standard deviations for each alloy have been calculated or 

estimated. 

 Zircaloy-2: =7.6 m 

 Zircaloy-4: =15.3 m 

 ZIRLO: =15 m 

 M5: =5 m 

Cladding Hoop Strain: The original hoop strain assessment cases that were available up to a 

burnup of around 45 GWd/MTU demonstrated that, on average, FRAPCON-3.4 slightly 

overpredicts cladding hoop strain by 0.1 percent strain, with a significant variation between the 

prediction and measured. This overprediction is conservative for hoop strain calculations. New 

high-burnup ramp test rods demonstrate that, at burnups between 45 and 55 GWd/MTU, 

FRAPCON-3.4 begins to underpredict hoop strain during power ramps with long hold times. 

This underprediction appears to become larger with increasing burnup. On average, above 

45 GWd/MTU, FRAPCON-3.4 underpredicts cladding permanent hoop strain by 0.3 percent for 

long hold time ramps. Despite these overpredictions at lower burnup and underpredictions above 

45 GWd/MTU for long hold times, FRAPCON-3.4 provides reasonable hoop strain predictions 

up to 62 GWd/MTU, considering the large degree of scatter in strain for these ramp data. 

However, to address underpredictions at higher burnups, new code capability should be 

developed for the code to predict hoop strain at higher burnup.

Steady-State Assessment Cases 

A.1 Halden IFA-432 Rods 

The IFA-432 test (Lanning, 1986) was irradiated under a research program on fuel rod steadystate performance sponsored by the U.S. Nuclear Regulatory Commission (NRC) from 1974 to 

1986. The IFA-432 test assembly was a heavily instrumented, six-rod assembly irradiated in the 

Halden heavy boiling-water reactor (HBWR), Norway, from 1975 to 1984. The purpose was to 

test the long-term steady-state performance of BWR-6 type fuel rods, operated at power levels 

that were at the upper bound for full-length commercial fuel rods. The fuel pellets were 

fabricated at Pacific Northwest National Laboratory (PNNL) and shipped to Norway; final rod 

and assembly fabrication was completed at the Halden site. Destructive examinations of selected 

rods were carried out at Harwell Laboratories, UK. 

The assembly included six instrumented rods and three replaceable noninstrumented spares. 

Each instrumented fuel rod had a centerline thermocouple in both the top and the bottom end of 

the fuel column and a pressure transducer to monitor rod internal pressure. The assembly 

instrumentation included six vanadium self-powered neutron detectors (SPNDs) and one cobalt 

neutron detector, together with rod elongation sensors at each rod position, coolant thermocouples 

at the top and bottom of the assembly, and a coolant flow meter (turbine). 

The test rods were designed to simulate BWR-6 rod cladding type and radial dimensions, with 

variations in fuel-cladding gap sizes, fuel types, and fill gas compositions. The fuel rod length 

was much shorter than full-length (~144-inch) commercial reactor rods to fit well within the short 

length of the Halden reactor core. Fuel rod overall length was 25 inches, with an active fuel 

column length of 22.8 inches. The overall void volume was held to 0.5 cubic inches (by selection 

of a ~1-inch plenum length at the upper end); this was done to approximate the ratio between fuel 

volume and void volume found in full-length rods. The cladding for all rods was Zircaloy-2. 

Rods 1, 2, and 3 all had typical high-density (95 percent theoretical density (TD)) stable sintered 

UO2 fuel pellets and helium fill gas at 1 atm pressure; slight differences in the pellet diameters 

created variations in fuel-cladding gap size among the rods. Data taken from rod 1 upper and 

lower thermocouple, rod 2 lower thermocouple, and rod 3 upper and lower thermocouple during 

the first ramp to power were used in the beginning-of-life (BOL) temperature assessment. Data 

from the rod 1 lower thermocouple and the rod 3 lower thermocouple were used in the 

temperature assessment as a function of burnup. It should be noted that much of the helium fill 

gas was lost from some of these rods during irradiation due to leakage past the thermocouple 

penetration through the end caps. 

The input files used for the assessments listed in Table 2.1 are shown below.

A.2 Halden IFA-513 Rods 

The IFA-513 test fuel assembly (Bradley et al., 1981) was irradiated in the Halden reactor in 

Norway from November 1978 to mid-1981 under a continuation of an NRC program to test the 

performance of BWR-6 type fuel and the effects of fission gas contamination of the helium fill 

gas. 

Rods 1 and 6 both had typical high-density (95 percent TD) stable sintered uranium dioxide 

(UO2) fuel pellets. Rod 1 had helium fill gas at one atmosphere while rod 6 had 23 percent xenon 

and 77percent helium fill gas at one atmosphere. Data taken from rod 1 upper and lower 

thermocouple and rod 6 upper and lower thermocouple during the first ramp to power were used 

in the BOL temperature assessment. Data from the rod 1 upper and lower thermocouple and the 

rod 6 upper and lower thermocouple were used in the temperature assessment as a function of 

burnup. 

The input files used for the assessments listed in Table 2.1 are shown below.

A.3 Halden IFA-633 Rods 

The IFA-633 test assembly consisted of six instrumented rods (three short binderless route (SBR) 

mixed oxide (MOX) fuel rods and three UO2 rods) irradiated from beginning of life through a 

burnup of 31 gigawatt-days per metric ton of metal (GWd/MTM). Rod 6 (Wright, 2004) was the 

only MOX rod instrumented with both a fuel centerline thermocouple and a pressure transducer 

such that temperature and fission gas release (FGR) measurements can be compared. Rods 1, 3, 

and 5 (Rø and Rossiter, 2005) were UO2 rods instrumented with centerline thermocouples and 

were used to assess the FRAPCON-3.4 predictions of temperature as a function of linear heat 

generation rate (LHGR) at BOL. This test assembly experienced a power ramp at a burnup of 

approximately 20 GWd/MTM to achieve fission gas bubble interlinkage. The MOX fuel was 

fabricated with the SBR process with a grain size of 7.5 microns and was typical of commercial 

fuel. 

Rod 6 was used to assess the FRAPCON-3.4 temperature predictions for MOX as a function of 

burnup and the MOX FGR predictions. The input files used for the MOX temperature and FGR 

assessments are shown below. The input file that includes the central hole was used for the 

temperature assessment since the temperature was measured on hollow pellets. The input file that 

does not include the central hole was used for the FGR assessment since most of the FGR comes 

from solid pellets. Rods 1, 3, and 5 were used to assess the FRAPCON-3.4 temperature 

predictions for UO2 as a function of LHGR at BOL. These input files are not included in this 

report due to the limited availablility and sensitivity of this information.

A.4 Halden IFA-677.1 Rods 

The high initial rating test, IFA-677.1 (Thérache, 2005; Jošek, 2008), was loaded in the Halden 

reactor in December 2004 and had completed six cycles of irradiation under HBWR conditions as 

of September 2007, achieving a rig average burnup of 30 GWd/MTU. The single cluster 

contained six rods supplied by Westinghouse, Framatome ANP, and Global Nuclear Fuel (GNF), 

all fitted with pressure transducers, fuel centerline thermocouples in both ends, and fuel stack 

elongation detectors, and with a cladding extensometer for one of the rods. The experiment was 

aimed at investigating the performance of modern fuels subjected to high initial rating with 

respect to thermal behavior, dimensional changes (densification and swelling), FGR, and 

pellet/cladding mechanical interaction (PCMI). 

Rod 2 (Framatome ANP), rod 3 (GNF), rod 4 (GNF), and rod 6 (Westinghouse) were all used to 

assess the BOL UO2 temperature predictions of FRAPCON-3.4 as a function of LHGR. In 

addition, rod 2 was used to assess the UO2 temperature predictions as a function of burnup up to 

32 GWd/MTU. The input files used for these assessments are shown below.

A.5 Halden IFA-562 Rod 

The Halden Ultra High Burnup (HUHB) test fuel assembly (IFA-562) (Wiesnack, 1992) was 

initiated by the Halden reactor project to demonstrate the effect of burnup on fuel thermal 

conductivity. The HUHB configuration of the assembly consisted of six rods, four of which were 

instrumented with centerline expansion thermometers and two with pressure transducers. The 

rods were under irradiation in the Halden reactor from September 1989 to 1997. Documented 

data for fuel center temperatures and linear heat ratings are available to a rod-average burnup of 

76 megawatt-days per metric ton of uranium (MWd/MTU). 

Four rods (rods 15, 16, 17, and 18) contained “expansion centerline thermometers.” These are 

tungsten (1.8 percent ZrO) rods that run the full length of the rod on the inside of the pellets and 

gage the average center temperature of each rod via thermal expansion of the rod detected by 

resistance change. Two rods (rods 13 and 14) each contained a pressure transducer for measuring 

rod internal pressure. The assembly instrumentation included four SPNDs, three of which were 

located coplanar at the top of the assembly and one near the bottom to define the thermal neutron 

flux distribution within the assembly. 

The behavior of LHGR and measured temperatures were very similar for all four rods with 

temperature sensors. One rod (number 18) was selected for comparison to FRAPCON-3 

predictions. The input file used for the UO2 temperature assessment as a function of burnup is 

shown below.

A.6 Halden IFA-597.3 Rod 

The fuel segments for the high-burnup integral rod behavior test IFA-597 (Matsson and Turnbull, 

1998) were refabricated from fuel rod 33-25065, which was irradiated in the Ringhals 1 BWR, 

Sweden, for approximately 12 years. The irradiation of this rod and its sibling rod 33-25046 was 

performed in two stages. During the first irradiation, 1980 to 1986, the rods were part of 

Ringhals assembly 6477 and an approximate rod-averaged burnup of 35 GWd/MTU was reached. 

The rods were then placed into fuel assembly 9902 for a second period of irradiation from 1986 

to 1992 in Ringhals I. The locations of fuel rods 33-25065 and 33-25046 in this assembly were 

positions 9902/D5 and 9902/E4, respectively. A final rod-averaged burnup of 59 GWd/MTU was 

achieved. The burnup at the location of the Halden refabricated segments was estimated as 67 

GWd/MTU. 

Rods 8 and 9 were loaded into positions 2 and 5 in IFA-597.2 (second loading) and irradiated in 

Halden for some 20 days in July 1995. After a few power ramps, rod 9 failed and the assembly 

was withdrawn. During this time, useful data were generated on centerline temperature as a 

function of power. 

Rod 9 was removed and replaced by rod 7. The assembly was returned to the reactor as IFA597.3 (third loading); the irradiation started in January 1997 and continued to May of that year 

having accrued a further ~2 GWd/MTU. Data obtained included centerline temperature as a 

function of power and burnup, (rod 8), FGR estimated from the increase in rod internal pressure 

transducer (rod 8), and clad elongation (rod 7). 

The assembly was discharged and transported to Kjeller for post-irradiation examination (PIE). 

FGRs of 12.6 percent and 15.8 percent were measured from puncturing and gas extraction from 

rods 7 and 8, respectively. 

Rod 8 was used to assess the UO2 temperature and FGR predictions of FRAPCON-3.4. The input 

files used for these assessments are shown below.

A.7 Halden IFA-515.10 Rods 

IFA-515.10 (Tverberg and Amaya, 2001) contained hollow rods with centerline thermocouples 

irradiated up to a burnup of greater than 80 GWd/MTU. Two of the rods contain UO2 and two of 

the rods contain 8 percent gadolinia. However, the gadolinium used in these rods is composed of 

160Gd, which is a non-neutron absorbing isotope. In this way, the effect of the thermal 

conductivity degradation due to gadolinia can be separated from the power reduction that is 

typically seen in fuel containing gadolinia. For these rods, a special version of FRAPCON-3 was 

used that does not use the power profiles for neutron-absorbing gadolinia. 

Rods A1 and A2 are sibling rods of UO2 and urania-gadolinia (UO2-Gd2O3), respectively, and 

experience very similar power histories. This is also true for rods B1 and B2. Halden has 

reported that the thermocouples failed in rods A1, A2, and B2 at the burnup indicated on Figures 

3.10, 3.35, and 3.36. After this point, the temperature data are no longer valid. 

These four rods were used to assess the FRAPCON-3.4 temperature predictions for UO2 and 

UO2-Gd2O3 fuel as a function of burnup. The input files used for the UO2 and UO2-Gd2O3

temperature assessment as a function of burnup are shown below.

A.8 Halden IFA-681 Rods 

IFA-681 (Klecha, 2006) consists of six rods that had been irradiated for four cycles or 340 days 

as of 2006. Ongoing irradiation is currently underway in the Halden reactor. The input files for 

the UO2 rods (rods 1 and 5) have been extended for six cycles to 507 days. All six of these rods 

were modeled using FRAPCON-3.4. Three of these rods contain solid pellets with hollow pellets 

at the top end and are equipped with centerline thermocouples in the top pellets. These three rods 

have UO2 (rod 1), 2 percent Gd2O3 (rod 2), and 8 percent Gd2O3 (rod 3) pellets. 

The other three rods contain all hollow pellets and are equipped with expansion thermometers. 

These three rods also have UO2 (rod 5), 2 percent Gd2O3 (rod 4), and 8 percent Gd2O3 (rod 6) 

pellets, with rod 6 being filled with 50 percent argon and 50 percent helium. 

For rod 3, there are some overpredictions (50 to 120°C) in the third and fourth cycles. This may 

be due to error in the temperature measurement or the estimation of the rod power level. This 

seems likely because the power level during these cycles is reported to increase from about 

21 kW/m to about 25 kW/m, while the temperature is reported to remain constant at about 850°C. 

It also seems strange for the power level in this rod to increase during these cycles while the 

power level in the other rods is constant during these cycles. 

These six rods were used to assess the FRAPCON-3.4 temperature predictions for UO2 and UO2-

Gd2O3 fuel as a function of burnup. The input files used for the UO2 and UO2-Gd2O3 temperature 

assessment as a function of burnup are not included in this report due to the limited availablility 

and sensitivity of this information..

A.9 Halden IFA-558 Rods 

IFA-558 (Turnbull and White, 2002) was an assembly commissioned by Central Electricity 

Generating Board in the UK (later Nuclear Electric) to investigate the effect of hydrostatic 

restraint on the onset of grain boundary interlinkage, and hence, FGR. The assembly comprised 

six identical, short boiling-water reactor (BWR) type rods, each fitted with a pressure transducer 

and upper and lower fuel centerline thermocouples. The rods contained 7 percent enriched 

hollow pellets supplied by British Nuclear Fuels, Ltd. (BNFL) with a 200 μm cold diametral fuelto-clad gap. In this way, PCMI effects were minimized, which would otherwise have introduced 

unwanted uncertainty in the hydrostatic pressure in the fuel pellets. 

The assembly was loaded in February 1986 and continued operation successfully until discharge 

at ~40 GWd/MTU in March 1992. The fuel rods were subsequently sent to AEA Technology for 

PIE. 

During startup, the rods were filled with helium gas at 2 bar pressure. Once the temperatures had 

stabilized at the prescribed normal operating powers, the pressures of four rods were altered in 

pairs in such a way as to minimize the spread of temperatures. Subsequently, rods 1 and 2 were 

operated at the maximum internal pressure of 40 bar, rods 5 and 6 operated at 20 bar, while rods 3 

and 4 remained at 2 bar. These pressures were maintained during all gas flow measurements and 

were only reduced at cold shutdown for safety reasons. The spread in fuel centerline 

temperatures during operation at around 35 kW/m for rods 2 through 6 was less than 60°C, but 

rod 1 was consistently some 50°C higher. 

Radioactive FGR was measured frequently, particularly in rod 3, and the measurements were 

used to monitor the onset of grain boundary interlinkage. In addition, all gas swept out of the 

rods was retained in separate cold traps to measure the activity of 85Kr, which was used to 

estimate the cumulative release of stable fission gas. This FGR data demonstrated that rod 

internal pressures up to 40 bar had little effect on FGR. 

Rod 6 was used to assess the UO2 temperature predictions of FRAPCON-3.4. The input file used 

for this assessment is shown below.

A.10 Halden IFA-629.1 Rods 

The IFA-629.1 (White, 1999) test involved two MOX test rods (rods 1 and 2), but only rod 2 was 

punctured for FGR measurement such that only this rod will be used for FGR comparison. Both 

rods are used for the temperature comparison as a function of burnup. The MOX fuel was 

fabricated using the MIMAS-AUC process by Belgonucleaire (BN). The mother rod for the IFA629.1 test rods was a full-length pressurized-water reactor (PWR) MOX rod irradiated for two 

cycles in the Saint-Laurent PWR, France, with rods 1 and 2 cut as segments from the full-length 

rod and refabricated into short segments. The rod 2 segment had a burnup of 29 GWd/MTM 

following commercial irradiation, which was extended to 40 GWd/MTM during the Halden 

irradiation. The maximum LHGRs in Halden were significant, at 35 to 40 kW/m. 

These two rods were used to assess the FRAPCON-3.4 temperature predictions for MOX as a 

function of burnup. Rod 2 was used to assess the FRAPCON-3.4 MOX FGR predictions. The 

input files used for the MOX temperature and FGR assessments are shown below. Input files that 

include the central hole were used for the temperature assessment since the temperature was 

measured on hollow pellets. The input file for rod 2 does not include the central hole for the FGR 

assessment since most of the pellets were solid.

A.11 Halden IFA-610 Rods 

One segment from four-cycle PWR MOX EdF rod N016 (which was base-irradiated for four 

cycles in the French Gravelines-4 reactors to a burnup of approximately 55 megawatt-days per 

kilogram of metal (MWd/kgM)) was re-fabricated and instrumented for use in the sequential IFA610.2,4 cladding liftoff experiments (Beguin, 1999) (Fujii and Claudel, 2001). The rod was 

tested under simulated PWR conditions in a pressurized water loop within the Halden reactor. 

The rod was connected to a gas supply system, and temperature measurements were made in both 

helium and argon fill gases at varying pressures. Fuel temperature data from helium gas fill 

periods were used to assess the FRAPCON-3.4 temperature predictions. 

The rod was base-irradiated at nominal LHGRs for ~1500 days. The final burnup for the segment 

was 54.5 MWd/kgM. The rod was instrumented with a fuel center thermocouple and a rod 

elongation sensor. Internal gas pressure was varied throughout the ~100 day IFA-610.2 test to 

investigate the threshold for cladding liftoff. The LHGR level during the IFA-610.2 test was 

steady at about 14 to 15 kW/m, and LHGR at the thermocouple was about 13.5 to 14 kW/m. 

In IFA-610.4, the LHGRs were similar at the beginning and drifted downward to 12.5 and 

12.0 kW/m for rod-average and thermocouple location, respectively (Fujii and Claudel, 2001). 

The test duration was similar to that of IFA-610.2 (100 days); however, after 50 days, questions 

of potential thermocouple degradation were raised, and code data comparison was only conducted 

over the first 50 days of the test. 

These two experiments were used to assess the FRAPCON-3.4 temperature predictions for MOX 

as a function of burnup. The input files used for the MOX temperature assessments are shown 

below.

A.12 Halden IFA-648.1 Rods 

The IFA-648.1 irradiation (Claudel and Huet, 2001) was simply a burnup extension at low LHGR 

for two refabricated instrumented segments from Gravelines-4 four-cycle PWR MOX rods, one 

segment each from rods N12 and P16. The irradiation was carried on at low LHGR under 

simulated PWR conditions in a pressurized water loop within the Halden reactor. The rods were 

then power-ramped in the follow-on IFA-629.3 test to investigate FGR and rod elongation 

behavior. 

The mother rods were base-irradiated at nominal LHGRs for ~1200 days. The final burnup 

for the rods N12 and P16 were 57 and 53 MWd/kgM, respectively. The two rods were 

instrumented differently upon refabrication. Rod 1 carried a fuel center thermocouple and a rod 

elongation sensor. Rod 2 carried a fuel center thermocouple and a pressure transducer. The 

LHGRs were kept deliberately low to accumulate more burnup without inducing FGR. 

These two rods were used to assess the FRAPCON-3.4 temperature predictions for MOX as a 

function of burnup. The input files used for the MOX temperature assessments are shown below.

A.13 Halden IFA-629.3 Rods 

Following base irradiation in a commercial PWR and further irradiation in Halden, two rods were 

further irradiated from 62 GWd/MTU to 68 to 72 GWd/MTU. The MOX fuel was fabricated 

using the MIMAS (micronized master blend) process. The documentation does not mention 

whether the UO2 was fabricated using the ammonium diuranate (ADU) or ammonium uranyl 

carbonate (AUC) process, but it is likely that the AUC process was used because the fuel was 

fabricated in the early 1990s. The MOX rods in IFA-629.3 (Petiprez, 2002) were irradiated for 

four cycles in the Gravelines-4 PWR; after this period, two experimental rods were refabricated 

from the full-length rods, refilled with helium, and loaded in the IFA 648.1 rig to accumulate 

more burnup at low powers and no additional gas release. Following irradiation in IFA-648.1, 

rod 6 was punctured and refilled with helium and the two rods were irradiated in IFA-629.3. 

These rods were irradiated up to a final burnup of 68 and 72 GWd/MTM and discharged for PIE. 

The measured gas release values for these rods have been obtained by puncture measurement. 

These two rods were used to assess the FRAPCON-3.4 temperature predictions for MOX as a 

function of burnup and the MOX FGR predictions. The input files used for the MOX 

temperature and FGR assessments are shown below. Input files that include the central hole were 

used for the temperature assessment since the temperature was measured on hollow pellets. Input 

files that do not include the central hole were used for the FGR assessment since most of the fuel 

column consisted of solid pellets.

A.14 Halden IFA-606 Rod 

The IFA-606 test assembly (Mertens et al., 1998; Mertens and Lippens, 2001) consisted of four 

refabricated rod segments from a full-length PWR MOX rod irradiated in the Beznau-1 reactor, 

Switzerland, at nominal LHGRs to a burnup of 50 MWd/kgM. The MOX fuel was fabricated 

using the MIMAS-AUC process by BN. Two test rods were instrumented with a fuel 

thermocouple and a pressure transducer, and irradiated under Halden conditions for 

approximately 30 days at elevated LHGR in “Phase 2” of the test, to determine FGR behavior. 

The code-data comparisons presented are for only rod 2 that measured FGR by rod puncture, with 

a 12.5 micron grain size. 

The fuel rod segment was instrumented with a pressure transducer and a fuel centerline 

thermocouple. The rod was base-irradiated at nominal LHGRs for ~1500 days. The rod segment 

reached a burnup of 49.5 GWd/MTM during commercial operation, with additional 30 days of 

irradiation in Halden for a total burnup of 50.6 GWd/MTM. 

This rod was used to assess the FRAPCON-3.4 temperature predictions for MOX as a function of 

burnup and the MOX FGR predictions. The input files used for the MOX temperature and FGR 

assessments are shown below. The input files that include the central hole were used for the 

temperature assessment since the temperature was measured on hollow pellets. The input file that 

does not include the central hole was used for the FGR assessment since most of the fuel column 

consists of solid pellets.

A.15 Halden IFA-636 Rods 

IFA-636 (Tverberg et al., 2005) contained both hollow pellets with centerline thermocouples and 

solid pellets irradiated up to a burnup of 25 GWd/MTU. FRAPCON-3.4 was used to model two 

of the rods from this assembly. These rods contained 8 percent gadolinia of the type typically 

used in power reactors. Centerline temperature data from IFA-636 rod 2 (hollow pellets) was 

used to compare to FRAPCON-3.4 predictions. 

Centerline temperature from IFA-636 rod 4 (solid rod) was estimated by Halden based on 

measurements from IFA-636 rod 2. These estimates were used to compare to FRAPCON-3.4 

predictions. These estimates may have more error than those for rod 2 due to both power 

uncertainties and uncertainties in estimating rod 4 temperature from rod 2 data. 

These two rods were used to assess the FRAPCON-3.4 temperature predictions for UO2-Gd2O3

fuel as a function of burnup. The input files used for the UO2-Gd2O3 temperature assessment as a 

function of burnup are shown below.

A.16 BR-3 Rods 

The DOE sponsored high-burnup irradiation of five well-characterized PWR-type test rods 

(Balfour, 1982; Balfour et al., 1982) in the BR-3 reactor, located in Mol, Belgium, to demonstrate 

the feasibility of extending commercial fuel rod burnup and thereby help to minimize radioactive 

waste disposal. These rods were fabricated by Westinghouse Corporation, whose staff also 

oversaw the PIEs. The PIE on the rods was carried out in the BR-2 hot cell facility at the Mol site. 

The rods were of basic PWR radial dimensions. Goal peak burnups exceeded 70 GWd/MTU.

The test rods were designed to simulate Westinghouse PWR (15 x 15) rod cladding type and 

radial dimensions, with variations in fuel enrichment and rod position providing variations in 

power history. The fuel rod length was much shorter than the full-length (~144-inch) commercial 

reactor rods and fit well within the short length of the BR-3 reactor core. The fuel rod overall 

length was 44 inches with an active fuel column length of 38.4 inches. 

Six rods were selected for comparison with FRAPCON-3.4 FGR predictions: 24-I-6, 36-I-8, 111-

I-5, 28-I-6, 30-I-8, and 332. Three of these rods were also selected for comparison with 

FRAPCON-3.4 void volume predictions: 24-I-6, 36-I-8, and 111-I-5. The input files used for the 

FGR and void volume assessments are shown below.

A.17 Zorita Rod 

Four fuel assemblies were initially irradiated in Zroita cycles 1 and 2. A total of 41 of the fuel 

rods in each assembly were removable, and 16 of these rods per assembly had high enrichment 

(4.08 to 6.6 wt% 235U) to achieve high linear power levels and burnups. One of these rods, rod 

332 (Balfour et al., 1982), with high enrichment that was irradiated up to 57 GWd/MTU, was 

selected as an FGR assessment case for FRAPCON-3.4. This case is shown below.

A.18 BNFL BR-3 Rods 

Battelle, Pacific Northwest Laboratories administered the international group-sponsored High 

Burnup Effects Program (HBEP), which continued from 1978 to 1990. The objective of the 

HBEP was to determine the effects of extended burnup on fuel rod performance, especially FGR. 

A variety of test rods and commercial power reactor rods were irradiated and examined under the 

HBEP, including two PWR assemblies (366 and 373) (Lanning et al., 1987; Barner et al., 1990) 

containing PWR-type test rods irradiated in a single assembly in the BR-3 test reactor in Mol, 

Belgium. Both of these assemblies experience high power, and the rods showed significant FGR. 

One rod from each assembly (rod DE from 373 and rod 5-DH from 366) was selected to be part 

of the UO2 FGR assessment cases for FRAPCON-3.4. These cases are shown below.

A.19 DR-3 Rods 

Test 022 comprised three UO2-Zr test fuel pins which were irradiated in the DR-3 reactor at Risø, 

Denmark, at 7.2 MPa (70 atm) system pressure (Bagger et al., 1978). A burnup of approximately 

42 GWd/MTU was accumulated at heat loads in the range of 35 to 53 kW/m. Fission gas 

analysis for two of the pins (PA29-4 and M2-2C) showed that the releases were 49 and 36 percent. 

The three almost identical test fuel pins had 12.6 mm sintered U02 pellets of 2.28 percent 

enrichment in 128 mm long stacks. The cladding was cold-worked and stress-relieved Zr-2 

tubing of approximately 0.55 mm wall thickness which had been autoclaved on both sides. The 

diametral pellet-clad clearance was 0.24 mm, and the pins were backfilled with 0.1 MPa (1 atm) 

helium. 

These two rods were used to assess the FRAPCON-3.4 UO2 FGR predictions. The input files 

used for the UO2 FGR assessments are shown below.

A.20 NRX Rods 

Several sets of UO2 fuel rods were irradiated in a pressurized water loop in the NRX reactor in 

Chalk River, Canada (De Meulemeester et al., 1973; Notley et al., 1967). The goal of these tests 

was to measure the gas pressures inside the rods, with the following objectives: 

 To determine the effects of fuel density on gas pressure and FGR. 

 To determine the effects of element power output variations on gas pressure and FGR. 

 To obtain data to test the predictions of a model for calculating the variation of gas pressure 

with power output. 

After irradiation, the rods were dimensioned and punctured for fission gas analysis. Samples 

from the rods were also analyzed for chemical burnup. Five of these rods were selected as UO2

FGR assessment cases for FRAPCON-3.4 because they provide FGR data at low burnups 

(< 11 GWd/MTU) while the other FGR assessment data were at burnups greater than 

20 GWd/MTU. Rods CBR, CBY, and CBP were irradiated together to 2.7 GWd/MTU in 85 days. 

Rod LFF was irradiated to 3.3 GWd/MTU in 108 days. Rod EPL-4 was irradiated to 

10.4 GWd/MTU in 100 days. 

The input files used for the UO2 FGR assessments are shown below.

A.21 EL-3 Rods 

Sixteen cartridges, each containing two rods, were irradiated in the EL-3 reactor, France, for a 

varying number of cycles to achieve burnups from 3 to 12 GWd/MTU. The aspects of the rods 

studied in this project were: 

 Macroscopic appearances: crack network, material movement, and dimensional changes 

 Microscopic appearances: recrystallization, pore redistribution, and new phases 

 Migration of fission products: stable gases released by the fuel and distribution of solid 

fission products 

Each cartridge was constructed of Zircaloy-2 and consisted of two separate stages, each 

containing a stack of UO2 fuel 123 mm high at each end, and in the central joint, space was 

provided for cobalt flux indicators. Each stage contained a chromel-alumel thermocouple located 

in the center of the stack. The cartridges were then filled with helium. 

After irradiation, the rods were dimensioned and punctured for fission gas analysis. Gamma 

scans were done as well as a radiochemical analysis. The rods 4110-AE2 and 4110-BE2 (Janvier 

et al., 1967) were used to assess the UO2 FGR predictions of FRAPCON-3.4. 

Both rods 4110-AE2 and 4110-BE2 contained fuel pellets with an as-fabricated density of 

10.52 g/cm3

. AE2 ran at a power of 17.6 kW/ft while BE2 ran at a power of 17.8 kW/ft. Rods 

4110-AE2 and 4110-BE2 were maintained throughout life at constant average LHGRs of 17.6 

and 17.8 kW/ft, respectively. Both ran with a flat axial power profile. The input LHGRs were a 

flat 17.6 and 17.8 kW/ft, with a few steps to get up to power. 

These two rods were used to assess the FRAPCON-3.4 UO2 FGR predictions at burnups less than 

15 GWd/MTU. The input files used for the UO2 FGR assessments are shown below.

A.23 Halden IFA-429 Rod 

The IFA-429 test fuel assembly (Turnbull, 2001) was initiated by NRC-Research and designed 

and fabricated by Idaho National Laboratory (with fuel pellet fabrication by PNNL) to 

demonstrate the effect of burnup, power level, and fuel grain size on fuel thermal behavior and 

FGR. The assembly consisted of 18 original short rods, arranged in three clusters of 6 rods each, 

and 15 noninstrumented spare and replacement rods. Rod DH is a replacement rod that was 

re-instrumented with a pressure transducer after it had attained about 30 GWd/MTU burnup at 

relatively low LHGR; the rod was then irradiated in IFA-519 at much higher and variable LHGR 

as part of a load-follow test, and eventually attained a peak burnup of 99 GWd/MTU. The FGR 

for this rod was obtained by puncture during PIE. It should be noted that the puncture data 

provided much higher release values than were estimated from the pressure transducer 

measurements because the rod pressures had exceeded the measurement capabilities of the 

pressure transducer.

The input file used for the FGR assessment is shown below.

A.24 Arkansas Nuclear PWR Rod 

DOE sponsored a program with ABB Combustion Engineering and Energy Operations, Inc. to 

improve the use of PWR fuel. The scope of this project was to develop more efficient fuel 

management concepts and an increase in the burnup of discharged fuel. 

Two 16 x 16 lead test assemblies were irradiated in the Arkansas Nuclear One-Unit 2 reactor 

(ANO-2). This is a PWR that operates at 2815 MW thermal. One of the assemblies, D039, was 

irradiated for three cycles and achieved a burnup of 33 GWd/MTU. The other assembly, number 

D040, was irradiated for five cycles and achieved a burnup of 52 GWd/MTU. 

Rod TSQ002 (Smith et al., 1994), irradiated in assembly D040, was of standard CE 16 x 16 

design and contained solid UO2. Assembly D040 was irradiated from 1979 to 1988 in ANO-2, 

cycles two through six. It accumulated 52 GWd/MTU assembly-average burnup. Rod TSQ002 

accumulated an end-of-life (EOL) rod-average burnup of 56.1 GWd/MTU. The rod-average 

LHGR varied from 2.75 to 6.95 kW/ft, with the higher values near BOL. 

This rod was used to assess the FRAPCON-3.4 UO2 FGR predictions, the EOL void volume 

predictions and the Zircaloy-4 corrosion predictions. The input files used for these assessments 

are shown below. The input for the EOL void volume contains one extra time step at room 

temperature and zero power so the room temperature void volume is calculated for comparison to 

the PIE measured volume.

A.25 Oconee PWR Rod 

DOE sponsored a long-term, multi-organizational program on the performance of light-water 

reactor (LWR) fuel rods during operation to extend burnups. As part of that program, Babcock 

and Wilcox (B&W) 15 x 15-type PWR fuel assemblies were irradiated to 3, 4, and 5 cycles in the 

Oconee PWR, operated by Duke Power Company. One assembly, 1D45, completed five cycles 

of irradiation in June 1983, having achieved an assembly average burnup of 50 GWd/MTU 

during 1553 effective full-power days. 

Several rods from the assembly were nondestructively and destructively examined in the B&W 

hot cells. This document summarizes the design and operating parameters for one rod, number 

15309 (Newman, 1986). Fuel density and microstructure, rod growth, cladding 

oxidation/hydriding, and diametral strain data are available for this rod together with FGR 

measurement via rod puncture and plenum gas analysis. The FGR for this low-powered rod was 

< 1 percent; but the cladding oxidation, growth, and diametral strain were significant. 

The rods were standard 15 x 15 full-length PWR rods. The rod initially had a rod-average LHGR 

of 7 to 8 kW/ft; however, this decreased to ~4 kW/ft by EOL. The axial power profile flattened 

early and remained relatively flat throughout life. 

This rod was used to assess the FRAPCON-3.4 UO2 FGR predictions, the EOL void volume 

predictions and the Zircaloy-4 corrosion predictions. The input files used for these assessments 

are shown below. The input for the EOL void volume contains one extra time step at room 

temperature and zero power so the room temperature volid volume is calculated for comparison 

to the PIE measured volume.

A.26 Halden IFA-651 Rods 

The IFA-651.1 rig (Blair and Wright, 2004) contained six fuel rod segments. Three of these rod 

segments contained inert matrix fuel and three rod segments contained MOX fuel. The MOX 

rods (rods 1, 3, and 6) were modeled with FRAPCON-3.4. Rod 1 MOX fuel was fabricated using 

an SBR that results in a relatively homogenous distribution of the PuO2 compared to MOX 

fabricated using the MIMAS process. Rods 3 and 6 were fabricated at Paul Scherrer Institute 

using a two-stage attrition milling process developed by the Korean Atomic Energy Research 

Institute. Micrographs provided appear to demonstrate that this process provides a homogenous 

distribution of PuO2 similar to that observed in the SBR process. 

These rods were irradiated for four cycles in the Halden reactor to a rod-average burnup between 

20 and 23 GWd/MTM. PIE showed that the fuel in rods 1 and 6 had an in-reactor densification 

of 2 percent, while the fuel in rod 3 had an in-reactor densification of 1 percent. These values 

have been entered into the code as input parameters. The measured gas release values used for 

model verification have been estimated from pressure measurements and are subject to greater 

uncertainty than measurements made by rod puncture. 

These three rods were used to assess the FRAPCON-3.4 temperature predictions for MOX as a 

function of burnup and the MOX FGR predictions. The input files used for the MOX 

temperature and FGR assessments are shown below. Input files that include the central hole were 

used for the temperature assessment since the temperature was measured on hollow pellets. Input 

files that do not include the central hole were used for the FGR assessment since most of the fuel 

column consists of solid pellets.

A.27 Advanced Test Reactor WG-MOX Rods 

Oak Ridge National Laboratory has reported base-irradiation LHGR histories and post-irradiation 

FGR for seven fuel pins irradiated in the ATR (Morris et al., 2000, 2001, 2005; Hodge et al., 

2002, 2003). These pins were irradiated in stainless steel capsules. Several pins were withdrawn 

for PIE after Phases II, III, and IV, after the pins had accumulated 21, 30, and 40 to 50 

GWd/MTM, respectively. The fuel used in these pins was fabricated using weapons-grade (WG) 

plutonium with a process similar to MIMAS. Fuel produced from WG plutonium differs from 

commercial MOX fuel in two ways. First, the WG MOX has greater amounts of 239Pu, and 

second, WG MOX contains small amounts of gallium. 

The measured gas release values for these rods have been obtained by puncture measurement. 

These three rods were used to assess the FRAPCON-3.4 MOX FGR predictions. The input files 

used for the MOX FGR assessments are shown below.

A.28 Gravelines-4 PWR Rods 

Halden Project has reported base-irradiation LHGR histories and post-irradiation (rod puncture) 

FGR for three full-length PWR MOX rods from Gravelines-4 reactor, France, which were 

subsequently sectioned to produce test rods for various instrumented tests (Beguin, 1999; Fujii 

and Claudel, 2001; Claudel and Huet, 2001; Petiprez, 2002). These commercial rods did not 

experience LHGRs in excess of 25 kW/m or temperatures in excess of 1500K, resulting in 

measured FGR below 5 percent. 

These three full-length commercial rods were used to assess the FRAPCON-3.4 MOX FGR 

predictions. The input files used for the MOX FGR assessments are shown below.

A.29 Beznau-1 M504 Rods 

The M504 program (Cook et al., 2003, 2004) consisted of four MOX rods irradiated in assembly 

M504 for four cycles in the Beznau-1 PWR reactor. The MOX fuel was fabricated using the SBR 

process, which results in a relatively homogenous distribution of the PuO2. These rods were 

irradiated up to a burnup between 37 and 43 GWd/MTM. The measured gas release values are 

relatively low and have been obtained from puncture measurements that have less uncertainty 

than those estimated from pressure measurements. 

These four rods were used to assess the FRAPCON-3.4 MOX FGR predictions. The input files 

used for the MOX FGR assessments are provided below.

A.30 Beznau-1 M308 Rod 

In the M308 program (Boulanger et al., 2004), segmented MOX rods were irradiated in the 

Beznau reactor up to peak burnups of 55 to 60 GWd/MTM. The MOX fuel was fabricated using 

the MIMAS–AUC process by BN, which results in larger PuO2 particle sizes than the SBR 

process. Sufficient detail on the power history and measured FGR was provided for Segment 2, 

such that this segment was modeled using FRAPCON-3.4. Only the cladding inner and outer 

diameters were provided for this segment; however, since these values were identical to the 

cladding inner and outer diameters for a Westinghouse 15 x 15 fuel rod, it was assumed the rest 

of the rod dimensions were the same as for a Westinghouse 15 x 15 fuel rod. 

This rod was used to assess the FRAPCON-3.4 MOX FGR predictions. The input file used for 

the MOX FGR assessment is shown below.

A.31 Halden IFA-597.4/.5/.6/.7 Rods 

IFA-597.4, 5, 6, and 7 (Koike, 2004) contained two MOX rods, containing fuel that was 

fabricated with the MIMAS-ADU process. Rod 10 contained mostly solid pellets, with a few 

hollow pellets at the top of the stack to accommodate the fuel centerline thermocouple. Rod 11 

contained all hollow pellets. These rods were irradiated for four cycles in the Halden reactor to a 

burnup between 35 and 37 GWd/MTM. The power history at the thermocouple position was 

provided for both rod 10 and rod 11. To determine the rod-average LHGR, for rod 10, the power 

history was increased by the ratio of average power to power at the top of the rod, and the ratio of 

the volume of a solid pellet to the volume of a hollow pellet. For rod 11, the power history was 

increased by only the ratio of average power to power at the top of the rod. For these pellets, the 

out-of-pile re-sintering tests of 24 hours at 1700°C showed a density increase of 0.46 percent. 

However, based on in-pile free volume and pressure measurements, it was determined that the 

maximum densification was 0.8 percent for rod 10 and 1.4 percent for rod 11. These measured 

values were used in the FRAPCON input files. 

The measured gas release values used for the FRAPCON-3.4 assessment have been estimated 

from pressure measurements and are subject to greater uncertainty than measurements made by 

rod puncture. 

These two rods were used to assess the FRAPCON-3.4 temperature predictions for MOX as a 

function of burnup and the MOX FGR predictions. The input files used for the MOX 

temperature and FGR assessments are shown below. Input files that include the central hole were 

used for the temperature assessment on rod 10 since the temperature was measured on hollow 

pellets. Input files that do not include the central hole were used for the FGR assessment on rod 

10 since most of the pellets consist are solid. The rod 11 input file is the same for the temperature 

and FGR assessment since all the pellets in rod 11 are hollow.

A.32 FUGEN Rods 

The MOX fuel assembly, E09 (Ozawa, 2004), was irradiated for 10 cycles in the Japanese 

advanced thermal reactor, Fugen. This assembly reached the highest assembly average burnup of 

38 GWd/MTM. The rods in this assembly were arranged in a circular pattern consisting of three 

concentric rings. The power history was approximately the same for all rods in a given ring. 

However, the power histories given for each ring did not provide the rod-average burnup that was 

measured in the pellets via gamma scanning. This discrepancy is most likely due to uncertainty 

in the linear heat rates that were provided. To model these cases, the power histories that were 

supplied were increased by a factor so the burnup calculated using these histories would be 

equivalent to the measured burnup. 

The pellet stack consisted of pellets with varying plutonium concentration in different axial 

regions. The top and bottom areas contained more plutonium than the central region. Since it is 

not possible to specify the plutonium concentration at various axial regions along the pellet stack 

in FRAPCON, two cases were run. In the first case, the plutonium concentration for the middle 

section was used for the entire rod, and in the second case, the plutonium concentration for the 

top and bottom sections was used for the entire rod. This allowed the effect of plutonium 

concentration on FGR to be seen. Plutonium concentration had very little impact on the predicted 

FGR (< 5 percent relative). 

The measured gas release values for these rods have been obtained by puncture measurement on 

several rods from each ring. 

These three rods were used to assess the FRAPCON-3.4 MOX FGR predictions. The input files 

used for the MOX FGR assessment are shown below.

A.33 Monticello BWR Rod 

A DOE program was completed in 1985 in which nine 8 x 8 fuel assemblies in the Monticello 

BWR were taken to high burnup (up to 45.6 MWd/MTM assembly average), and the rods were 

periodically examined nondestructively and sampled for destructive examinations (Baumgartner, 

1984). Four of the assemblies went for the “full term” from cycle 3 through cycle 9 from May 

1974 to September 1982. 

All of these rods have fully annealed Zircaloy-2 cladding. One of these rods, rod A1 from 

assembly MTB99 was used in the Zircaloy-2 corrosion assessment for FRAPCON-3.4. The input 

file used for the Zircaloy-2 corrosion assessment is shown below.

A.34 TVO-1 BWR Rod 

Battelle, Pacific Northwest Laboratories administered the international group-sponsored HBEP, 

which continued from 1978 to 1990. The objectives of the HBEP were to determine the effects of 

extended burnup on fuel rod performance, especially FGR. A variety of test rods and commercial 

power reactor rods were irradiated and examined under the HBEP, including nine full-length 5- 

and 6-cycle rods from the TVO-1 BWR in Finland (Barner et al., 1990). One of these rods was 

used to assess the corrosion performance of FRAPCON-3.4 for Zircaloy-2: rod number H8/36-6 

from 5-cycle fuel assembly 6116. 

The rod occupied position H8, which was the control blade corner position. The rod-average 

burnup at EOL was 44.6 GWd/MTU, with a peak value (confirmed by chemical burnup analysis) 

of 50.9 GWd/MTU. The rod-average LHGR varied between 12 and 24 kW/m (3.3 to 7.6 kW/ft), 

but large variations in the peak-to-average LHGR ratio occurred due to control blade movements. 

The input file used for the Zircaloy-2 corrosion assessment is shown below.

A.35 Vandellos PWR ZIRLO Rods 

A joint Spanish and Japanese effort irradiated a large number of full-length fuel rods for five 

cycles in the Spanish PWR Vandellos 2 (CSN, ENUSA, 2002). The rods were clad with ZIRLO 

and Mitsubishi Developed Alloy (MDA). Two of the ZIRLO rods (A06 and A12) have been 

modeled with FRAPCON-3.4 to assess the performance of the ZIRLO corrosion model to high 

burnup. 

The input files used for the ZIRLO corrosion assessment are shown below.

A.36 Gravelines-5 PWR M5 Rod 

One high-burnup rod was taken from the French reactor Gravelines-5 and refabricated for the 

reactivity-initiated accident (RIA) test CIP0-1, performed in the CABRI reactor, France (Segura 

and Bernaudat, 2002). This rod, N05, was clad with M5. Before refabrication, rod N05 was 

examined and the oxide layer thickness was measured. This full-length commercial rod has been 

modeled with FRAPCON-3.4 to assess the performance of the M5 corrosion model to high 

burnup. 

The input file used for the M5 corrosion assessment is shown below.

Power-Ramp Assessment Cases 

A.37 Ramped HBEP Obrigheim/Petten Rods 

The HBEP was an international, group-sponsored program administrated by Battelle Pacific 

Northwest Laboratory from 1979 to 1989 (Barner et al., 1990). The objective was to investigate 

the impact of extended burnup on fuel rod performance, especially FGR. A total of 81 rods of 

both BWR and PWR types were irradiated and examined under the program, with rod-average 

burnups ranging up to 69 GWd/MTU and peak pellet burnups up to 83 GWd/MTU. 

Under Task 2 of the program, full-length segmented rods were irradiated in commercial power 

reactors and then subjected to power ramps in test reactors. The rod segments comprised 

“rodlets” that were individual short-length fuel rods, mated end-to-end to form the full-length 

rods. Following irradiation to a variety of burnup levels, the rods were disassembled into the 

individual rodlets, and the rodlets were ramp-tested in test reactors. The peak LHGRs in these 

ramps ranged from 35 to 50 kW/m, and hold times ranged from 48 to 196 hours. The FGR 

during bumping was a function of the peak LHGRs and ranged from 10 to 45 percent. The prebump LHGRs ranged from 15 to 35 kW/m, as confirmed by calibrated nondestructive 85Kr 

activity determinations for the plenum gas, and the pre-bump FGRs were generally low (1 to 5 

percent). 

Two PWR-type ramped rodlets were chosen for comparison to FRAPCON-3.4 predictions. Both 

were fabricated by Kraftwerk Union (KWU), irradiated in the same fuel assembly in the 

Obrigheim PWR, Germany, and then power-ramped to approximately the same peak LHGR 

(41 to 43 kW/m) in the JRC-Petten test reactor, the Netherlands. Rodlet D200 attained 25 

GWd/MTU burnup in one reactor cycle at LHGRs of 25 ± 2 kW/m. Rodlet D226 attained 45 

GWd/MTU by further irradiation in the same assembly for two more cycles, with LHGR 

generally decreasing with time from 25 kW/m at BOL to ~17 kW/m during the final cycle. The 

fuel in these rods resulted in high fuel densification > 2.5 percent TD and high open porosity that 

is atypical of today’s fuel. Comparisons of the FGR data from these power-ramped rods to other 

power-ramped data with lower densification and open porosity fuel typical of today’s fuel 

suggests that these FGR data are higher than observed from today’s fuel. As a result, the 

FRAPCON-3.4 code tended to underpredict this data, which is not surprising. 

The post-bump FGR is greater for the higher-burnup rodlet D226 than for rodlet D200 (44 vs. 38 

percent), despite D226 having a smaller as-fabricated fuel cladding gap. The pre-ramp FGRs, 

based on 85Kr activity in the plenums, were very similar: 4.2 and 6.6 percent, respectively. 

Therefore, the net FGR during ramping is greater for rodlet D226, and this was attributed to 

burnup effects. This rodlet pair thus provides a test of the burnup effects inherent in the 

FRAPCON-3.4

The input files used for the UO2 FGR assessment are shown below.

A.38 Super-Ramp Rods 

The Super-Ramp Project was an international, group-sponsored program involving baseirradiation of segmented full-length BWR and PWR rods in various power reactors, followed by 

ramp-testing of the rod segments in the Studsvik R-2 test reactor, Sweden (Djurle, 1985). The 

project’s purpose was to establish the failure threshold for rods of varying types and burnup, and 

some rod segments did fail during high-power ramp testing. Rod segments that did not fail, 

however, gave data on FGR and cladding permanent hoop strain during EOL power transients. 

Three rod segments were selected as FGR assessment cases and nine rod segments were selected 

as cladding hoop strain assessment cases. These were all non-failed PWR rod segments, which 

had been base-irradiated in the Obrigheim PWR for three cycles up to a burnup of 34 to 

37 GWd/MTU. The segments were then ramp-tested in the Studsvik reactor to ramp terminal 

levels as high as 43 kW/m. The FGRs and residual cladding hoop strain were measured 

following the ramp test. 

The segmented PWR rods were designed in basic conformance with KWU’s 15 x 15 PWR fuel 

design. The general design specifications are given in Table A15.1. The fuel segment length was 

short, 39 cm overall and 31.5 cm active fuel length, to match well within the ~1 meter active 

length of the Studsvik reactor core. The diametral fuel-cladding gap was 145 microns (5.7 mils). 

The fuel pellet density is 95 percent TD, and the standard KWU densification test is only 

2.2 hours at 1700°C rather than the 24 hour densification test at 1700°C required by the NRC as a 

measure of maximum densification. Therefore, the quoted maximum densification for this fuel 

“none” may be low, and it may be as great as 1 percent TD—the latter figure is used as 

FRAPCON-3.4 input. 

The input files used for the UO2 FGR assessments and cladding hoop strain assessments are 

shown below.

A.39 Inter-Ramp Rods 

The Studsvik Inter-Ramp Project objective was to investigate the mechanical failure threshold for 

BWR 8 x 8 type fuel rods. Short rodlets with standard BWR 8 x 8 dimensions and components 

were fabricated by ABB/Atom specifically for the project and were base-irradiated to 

~20 GWd/MTU at low LHGRs before EOL ramping at rapid rate to high LHGRs to probe for 

cladding failure. Hold times at the ramp terminal (LHGR) level were 24 hours for non-failed 

rods. For the non-failed rods, post-ramp FGR was determined by rod puncture. 

Two of the non-failed, ramp-tested Inter-Ramp rods, numbers 16 and 18 (Mogard et al., 1979; 

Lysell and Birath, 1979), were selected for FGR and cladding permanent hoop strain assessment. 

Twenty short 21-inch rodlets were fabricated for the test, with nominal 8 x 8 BWR fuel rod 

characteristics, and there were some departures from these characteristics. Rods 16 and 18 were 

both “nominal rods” with 6-mil diametral gaps, 1 atm helium fill, and 95 percent TD solid, dished 

fuel pellets. The rods were irradiated in approximate BWR coolant conditions in pressurized 

loops within the Studsvik reactor. Rods 16 and 18 operated for ~550 days at LHGRs ranging 

from 20 to 40 kW/m and achieved burnups of 21 and 18 GWd/MTU, respectively. 

Rods 16 and 18 were then preconditioned for 24 hours at 29 and 25 kW/m, respectively, and then 

ramped at a rate of ~70 W/m per second to terminal levels (maximum peak LHGR values) of 48 

and 41 kW/m, respectively, where they were each held for 24 hours, during which the coolant 

was monitored for added radioactivity (indicating rod failure). Neither rod failed. Therefore, 

puncture and FGR determinations were feasible, and were performed.

The input files used for the UO2 FGR assessments and cladding hoop strain assessments are 

shown below.

A.40 Ramped Halden/DR-2 Rods 

The Risø Fission Gas Release Project was an international, group-sponsored program 

administrated by Risø Laboratories, Denmark, from 1980 to 1981. The objective was to 

investigate the impact of extended burnup and EOL power ramping on FGR in BWR-type fuel 

rods. This was done by performing power-bumping tests in the DR-2 reactor (Denmark) on 9 of 

the 14 rods irradiated in test fuel assembly IFA-148. This assembly was operated in the Halden 

reactor, Norway, from 1968 to 1979. The power ramps featured 24-hour hold periods at the peak 

power level, with the peak power level varied among the tests. These tests were supplemented by 

nondestructive examinations before and after the bumping irradiations, rod puncturing/gas 

analysis on all tested rods, and detailed destructive examinations on selected rods. 

Three of the bumped rods were selected as FRAPCON-3.4 FGR assessment cases: rods F7-3, F9-

3, and F14-6 (Knudson et al., 1983), which had rod-average burnups of 35, 33, and 27 

GWd/MTU, respectively. The analyses of plenum gas 85Kr activity before and after bumping 

were performed, and these were calibrated against the post-bump rod puncture results to yield an 

estimate of the net FGR caused by the power bumping. Thus, these cases provide the opportunity 

to assess the transient power induced short-term FGR predictions of the FRAPCON-3.4 FGR 

model. 

The IFA-148 assembly contained a total of 14 short BWR-type test rodlets, with 7 rods each in 

two clusters (upper and lower clusters). The fuel pellets were 5 percent enriched sintered urania, 

with some variations in density and grain size. These two assessment cases, the nominal grain 

size and the fuel pellet densities, are equal (13 to 16 micron grain size and density of 93.4 percent 

TD, with a 0.6 percent increase upon resinter). The rods were initially filled with 1 atm helium 

fill gas. 

The input files used for the UO2 FGR assessments are shown below.

A.41 Risø-3 Ramped Rods 

The Risø National Laboratory in Denmark has carried out three irradiation programs of slow 

ramp and hold tests, so called “bump tests,” to investigate FGR and fuel microstructural changes. 

The third and final project, which took place between 1986 and 1990, bump-tested fuel reinstrumented with both pressure transducers and fuel centerline thermocouples. 

The innovative technique used for refabrication involved freezing the fuel rod to hold the fuel 

fragments in position before cutting and drilling away the center part of the solid pellets to 

accommodate the new thermocouple. 

The fuel used in the project was from IFA-161 irradiated in the Halden BWR to 52 GWd/MTU, 

GE BWR fuel irradiated in Quad Cities 1 and Millstone 1 from 23 to 45 GWd/MTU, and ANF 

PWR fuel irradiated in Biblis A (Germany) to 43 GWd/MTU. All these rods were subsequently 

ramped in the DR-3 reactor. 

Four of the GE BWR rods (GE2, GE4, GE6, and GE7) (Chantoin et al., 1997) and two of the 

ANF rods (AN1 and AN8) (Chantoin et al., 1997) were selected to assess the FRAPCON-3.4 

predictions of UO2 FGR and cladding hoop strain. The input files used for the UO2 FGR 

assessments and cladding hoop strain assessments are shown below.

A.42 B&W Rods Ramped at Studsvik 

Three well-characterized 1.10 m long rodlets that had been irradiated to burnups slightly greater 

than 62 GWd/MTU in ANO-1 were ramp tested in the Studsvik R2 experimental reactor (Wesley 

et al., 1994). Peak power levels of 39.5, 42.0, and 44.0 kW/m and a 12 hour hold time were 

selected for these tests. No failures were experienced during testing and no incipient cracks were 

detected in the cladding during the post-ramp examinations. The FGR after the ramp was 

measured. Two of these rods (rods 1 and 3) were used in the assessment of the FRAPCON-3.4 

UO2 FGR predictions. 

The input files for these two rods are shown below.

A.43 Regate Rod 

This Regate experiment (Struzik, 2004) deals with the study of FGR and fuel swelling during 

power transient at medium burnup. The rod was base-irradiated in the Gravelines-5 PWR and 

then re-irradiated in the test reactor SILOE in Grenoble, France. Since the rod was initially a 

segmented rod, the refabrication process prior to loading in the test is minor. In particular, the 

rod was not purged of its fission gases following refabrication. 

The segmented rod consisted of UO2 fuel with 4.5 percent enrichment. It was irradiated up to 

47 GWd/MTU. In the SILOE reactor, the rod was given a conditioning power step of 

195 W/cm for 48 hours and then was ramped at 10W/cm/min and held at 385 W/cm for 90 

minutes. This rod is particularly valuable for examining FGR for power ramps of short time 

duration because the other power ramped UO2 rods used for FRAPCON-3.4 assessment were for 

hold times of 4) hours or greater. 

This rod was used as part of the FRAPCON-3.4 UO2 FGR assessment. The input file used for the 

UO2 FGR assessment is shown below.

A.44 Beznau-1 M501 Rods 

Two MOX rods were irradiated for three cycles in the Beznau-1 PWR up to a rod-average burnup 

between 34 and 37 GWd/MTM. The MOX fuel was fabricated using SBR that results in a 

relatively homogenous distribution of the PuO2. One of these rods had a high plutonium 

enrichment (5.54 wt%) and one had a medium plutonium enrichment (3.72 wt%). After this, 

eight rodlets were refabricated from these two rods. Rodlets HR-1 to HR-4 (White et al., 2001; 

Cook et al., 2000, 2003, 2004) were refabricated from the high-enrichment rod, number 4463, and 

rodlets MR-1 to MR-4 (White et al., 2001; Cook et al., 2000, 2003, 2004) were refabricated from 

the medium enrichment rod, number 7612. These rodlets were ramp tested in the Petten high flux 

reactor. The ramp consisted of a 60 hour hold time at a preconditioning level followed by a ramp 

to a higher level with a hold of 12 hours for all the rodlets except MR-4, which was only held at 

the higher level for 20 minutes. It should be noted that the preconditioning and ramp power 

levels listed in the documents are the peak node powers. These values have been divided by the 

peak-to-average ratio to determine the rod-average power levels for these ramp tests. 

These eight rodlets were used to assess the FRAPCON-3.4 MOX FGR predictions. The input 

files used for the MOX temperature and FGR assessments are shown below.

A.45 Studsvik Cladding Integrity Project Ramped Rods 

The Studsvik Cladding Integrity Program (SCIP) has subjected 10 test rods to power ramp testing 

(Kallstrom, 2005). Each test rod was subjected to a designated type of ramp test, which included 

staircase, short hold, long hold, and two-step power ramp tests. Each test rod was fabricated from 

a rodlet sectioned from a previously irradiated father rod. 

Four ramp test rods were made by refabricating rodlets from BWR father rods that had been 

irradiated in Kernkraftwerk, Leibstadt. These test rods were labeled KKL-1, KKL-2, KKL-3, and 

KKL-4 and were irradiated to approximately 63, 67, 56, and 40 megawatt-days per metric ton of 

uranium (MWd/kgU) average rodlet burnup, respectively. Before ramp testing, each rod was 

conditioned for a designated period of time and LHR. The first ramp test, KKL-1, was aimed at 

defining the ramp terminal level where rod failure would occur. The rod was subjected to a 

staircase ramp, and after six steps of 5 kW/m with a 1 hour hold time between steps, the rodlet 

failed after 40 minutes at an LHR of 42 kW/m. To determine if the failure, which was caused by 

an outside-in crack, was dependent on burnup, a similar test was performed on KKL-3. A 

staircase ramp consisting of eight steps at 5 kW/m with a 1 hour hold time between steps was 

performed up to 52 kW/m. After holding for 12 hours at 52 kW/m, no failure was observed in 

KKL-3. Ramp tests of the other two rods, KKL-2 and KKL-4, were aimed at studying the 

geometric changes during a power transient and their dependence on burnup. The rods, KKL-2 

and KKL-4, were held at 41 and 45 kW/m for 30 and 5 seconds, respectively. Neither KKL-2 or 

KKL-4 failed during ramp testing. 

Two ramp test rods, M5-H1 and M5-H2, were fabricated from the same father rod, which had 

been irradiated in Ringhals 4 PWR and used to study the influence of holding time on geometric 

changes. The rods, M5-H1 and M5-H2, had been irradiated to a rodlet-average burnup of 67 and 

68 MWd/kgU, respectively, and conditioned for a designated period of time and LHR prior to 

ramp testing. During the short hold and long hold ramp tests, holding times of 5 seconds and 12 

hours were used on M5-H1 and M5-H2, respectively, at an LHGR of 40 kW/m. Neither rod 

failed during the ramp test. 

Ramp testing was performed on rod O2 (55 MWd/kgU burnup) to study geometric changes and 

PCI. Rod O2 had been previously irradiated in the BWR Oskarshamn 2 (Sweden) to an average 

rodlet burnup of 55 MWd/kgU. A short hold ramp test was performed by holding rod O2 at an 

LHR of 45 kW/m for 30 seconds. Rod O2 did not fail during the ramp test. 

Ramp test rods Z-2, Z-3, and Z-4 had each been irradiated to 76 MWd/kgU. Rods Z-3 and Z-4 

were irradiated in the PWR North Anna while rod Z-2 was irradiated in the PWR Vandellos. Rod 

Z-3 was intended to study the hydrogen embrittlement by ramping the rod to an LHR of 40 kW/m 

for a 5 second hold. However, failure occurred at an LHR of 39 kW/M, which prevented the 

short hold ramp test from being completed. Rods Z-2 and Z-4 were intended to study delayed 

hydrogen cracking (DHC), and were subjected to two-step power ramp tests. Rod Z-2 was 

initially ramped to an LHR of 35 kW/m and held for 6 hours before being ramped to an LHR of 

40 kW/m and held for an additional 6 hours. Rod Z-4 was initially ramped to 33 kW/m and held 

for 6 hours before being ramped to 38 kW/m and held for an additional 6 hours. The rods, Z-2 

and Z-4, did not fail during the two-step power ramp. 

These 10 rods were used to assess the FRAPCON-3.4 predictions of cladding hoop strain. The 

input files used for these cases are not included in this report due to the limited availablility and 

sensitivity of this information.
