Abstract

The LOFT experiment LP-02-6 was simulated using the RELAP5/MOD3.2 code to assess its

capability to predict the thermal-hydraulic phenomena in LBLOCA of the PWR. The reactor

vessel was modeled with two core channels and split downcomer for a base calculation. The

results of the base calculation show that the code can not predict the early bottom-up

quenching which is a distinguished phenomenon of the experiment LP-02-6, mainly due to the

deficiency of break flow model.

The discharge coefficient sensitivity study was performed to show that the calculated

subcooled break flow which might significantly affect the early bottom-up quenching is

dependent on the coefficient. More detailed modeling of the cross flow in the split downcomer

was performed, but, resulted in little improvement on the predictability of bottom-up quenching.

Additional calculation using the RELAP5/MOD3.1 instead of RELAP5/MOD3.2 showed that

there is no large difference between the versions in the simulation of LBLOCA.

Executive Summary

This report presents the results of RELAP5/MOD3.2 assessment in the prediction

of the thermal-hydraulic behavior under the conditions of Loss of Fluid Test(LOFT)

LBLOCA Experiment LP-02-6. The assessment was purposed to determine whether the

code can predict the major phenomena of LOFT LP-02-6 and to provide some useful

information to code developers and users.

Experiment LP-02-6 was conducted on October 3, 1983. It was the forth experiment conducted in the LOFT facility at the Idaho National Engineering Laboratory(INEL) under the auspices of the OECD. This experiment, which was designed to

meet requirements outlined by the USNRC as specified in the OECD LOFT Project

Agreement, simulated a double-ended off-set shear of a commercial PWR main coolant

inlet pipe coincident with the loss of offsite power. Experiment LP-02-6 addressed the

response of a PWR to conditions closely resembling a USNRC "Design Basis Accident"

in that prepressurized fuel rods were installed and minimum US emergency coolant injections were used.

A base case calculation using RELAP5/MOD3.2 with the typical LOFT nodalization and default break flow model was conducted. The results of the calculation were

compared with the experiment data in terms of loop behavior, ECCS performance, vessel

phenomena, and fuel thermal response. It was disclosed from the comparison that the

code has poor predictability of the important thermal-hydraulic phenomena such as the

early bottom up quenching during the blowdown. A primary cause of this poor prediction was inferred as the overprediction of subcooled break flow. The overprediction of

subcooled break flow bring about the early end of subcooled break flow, early core heat

up during the blowdown, the early initiation of bottom-up quenching and little amount of

bottom-up flow.

To identify the effect of break flow model in the base case calculation, several calculations were performed with changing discharge coefficient. It was concluded that deV
creased discharge coefficient reduces the peak subcooled break flow and it helps the

code better predict the early bottom up quenching.

Another sensitivity study was performed to identify the effects of the modeling of

cross flow in the split downcomer annulus. All the downcomer volumes of each side

were connected by cross flow junctions while only the top volume of downcomer annulus was connected by a cross flow junction in the base case calculation. This change of

nodalization resulted in little improvement on the prediction of bottom up quenching,

which means that the core thermal-hydraulic behavior is not dependent on the number of

cross flow junctions.

Additional calculation using the RELAP5/MOD3.1 was performed to catch the

improved features of RELAP5/MOD3.2 compared with RELAP5/MOD3.1. The versions showed nearly identical results, but, RELAP5/MOD3.2 predicted better the thermal

behavior in the both end parts of the core than RELAP5/MOD3. 1.

1. INTRODUCTION

This report presents the results of code assessment of RELAP5/MOD3.2 using the

LOFT experiment LP-02-6. The assessment was performed within the Code Applications

and Maintenance Program(CAMP) organized by the U. S. Nuclear Regulatory Commission(NRC).

The experiment LP-02-6 was the first large break LOCA simulation which was designed to represent the design basis accident conditions. The distinguished thermalhydraulic phenomena of the experiment LP-02-6 is a positive bottom-up core flow,

which resulted in bottom-up quench of central fuel assembly during the blowdown period,

due to the long-term pump coast down.

The objective of this study is to identify effectiveness and deficiencies of

RELAP5/MOD3.2 in predicting thermal-hydraulic phenomenon specific to LBLOCA

such as bottom-up quenching. RELAP5/MOD3.2 is a recently released version of

RELAP5/MOD3 which was developed by improving the modeling base of

RELAP5/MOD2. RELAP5/MOD2 was assessed using the LP-02-6 test data by

Lfbbesmeyer [2]. He concluded that it could not predict the early bottom-up rewetting

which occurred between 4 and 8 seconds of the blowdown phase.

It is well known that RELAP code is very strongly dependent upon user specific

input parameters. The discharge coefficient at the break valve affects significantly on the

resultant thermal-hydraulic behavior in the analysis of LBLOCA. To find out the influence of discharge coefficient in the calculation of LP-02-6, sensitivity calculations on the

discharge coefficient were carried out.

Transversal flow in the downcomer, which has been believed to have effects on the

core flow behavior, has been modeled by cross flow junction between downcomer upper

volumes of both loop sides. A more detailed modeling of the transversal flow by connecting all the volumes of both loop sides with six cross flow junctions was tried to get better

I
prediction of core flow behavior.

Finally, a calculation using RELAP5/MOD3.1 in place of RELAP5/MOD3.2 was

conducted, though it is generally thought that there is no significant change between

these versions in the analysis of LBLOCA, to get knowledge of the improved features of

RELAP5/MOD3.2.

A brief description of the LOFT system and the LP-02-6 experiment are provided

in Chapter 2. The code and modeling basis for the base case calculation is described in

Chapter 3. The results of the base case calculation are discussed in Chapter 4. The scope

and results of sensitivity studies are presented in Chapter 5. Chapter 6 describes the run

statistics for the base case calculation and conclusions and recommendations from this

assessment are presented in Chapter 7. The input list for steady-state run and transient

run of the base case is attached in Appendix.

2. FACILITY AND TEST DESCRIPTIONS

2.1 LOFT facility

The LOFT(Loss of Fluid Test) facility at Idaho National Engineering Laboratory

was designed to simulate the major component and system responses of commercial

PWR during LOCA. It is a scaled representation of a commercial PWR of Westinghouse

type having 4 loops with a volume ratio of 1/60. The experimental assembly includes five

major subsystems which have been instrumented such that system variables can be measured and recorded during a LOCA simulation. The subsystems consist of a reactor

vessel with a nuclear core, an intact loop, a broken loop, the blowdown suppression system, and the emergency core coolant system. The entire nuclear core consists of five

square and four triangular fuel bundles with a total of 1300 fuel pins each of 1.67 m long

and an outside diameter of 10.72 mm. The overall configuration is shown in Figure 2.1

and complete information on this system is provided in Reference 1.

2.2 Experiment LP-02-6

Experiment LP-02-6 was completed on October 3, 1983, in the LOFT facility located at the Idaho National Engineering Laboratory. It was the first large-break LOCA

simulation and the fourth experiment conducted under the auspices of the Organization

for Economic Cooperation and Development(OECD) LOFT Project. This experiment

simulated a double-ended offset shear of a pressurized water reactor(PWR) main coolant

inlet pipe, and was initiated from conditions similar to PWR operating conditions.

Prior to the experiment, LOFT facility was set to have a primary system pressure

of 15.0 MPa, primary system cold leg and hot leg temperature of 560K, and 590K respectively, and a loop mass flow rate of 248.7 kg/sec. Initial reactor power level was 46

3
MW with a maximum linear heat generation rate (LHGR) of 48.8 kW/m. Table 2.1 presents a summary of initial conditions of the experiment.

The experiment was initiated by opening both the Quick Opening Blowdown

Valves(QOBV) in hot and cold leg. Reactor was scrammed on low hot leg pressure at

0.1 secs and the pumps were tripped at 0.8 secs. The pumps coasted down until 16.5

secs when their rotational speed fell below the trip point and they were decoupled from

their flywheels. Flow in the core reversed almost instantaneously with experiment initiation, and the fuel rod cladding temperatures started to increase due to stored thermal

energy at 0.9 secs. The entire core heated up until 5.2 secs, when positive core flow was

again established due to choking of the flow in the broken cold leg. This positive core

flow quenched the lower -2/3 of the core until -10 secs when flow in the intact cold leg

decreased to below that of the broken cold leg and the core again started to heat up. A

partial top-down core quench initiated at 14.8 secs and lasted until 18.6 secs. The lower

plenum was filled by 30.7 secs, the core quench was complete by 56 secs, and core reflood was complete by 59 secs. Thermal-hydraulic sequence of main events observed in

the experiment is summarized in Table 2.2.

3. CODE AND MODELING DESCRIPTION

RELAP5/MOD3.2 used in this assessment was the very version(without any

modification) received at October 1995 from USNRC. Since any RELAP5 input specific to LP-02-6 experiment was not obtained from INEL, a reference input was developed by authors based on the input which was used in the previous LP-LB-1 assessment

by Liibbesmeyer [3].

3.1 Input Modeling

The base nodalization used to simulate the LOFT experiment LP-02-6 in this study

is shown in Figure 3.1. This nodalization and input deck are based on those used to calculate the LP-LB-1 experiment with RELAP5/MOD2 by LUibbesmeyer [3]. Modifications implemented into the original input are as follows : (1) General changes suitable to

RELAP5/MOD3(e.g. heat structure), (2) Introduction of ECCMIX component, (3)

Changes in the number of volumes of pressurizer (six to twelve), (4) Changes in the

number of axial nodes of core channel, (5) LP-02-6 experiment specific modifications

The reactor vessel is modeled by three hydraulic channels representing reactor

core(volume 230, 231, and 235), two downcomer channels(volume 200 to 210 and 270

to 280 respectively), lower plenum(volume 220 to 225) and upper plenum with the vessel dome(240-260). Top volumes of each downcomer channel(volume 200 and 270) are

connected with single cross flow junction(junction 290) which has energy loss coefficient

of 1.8341. Nozzle bypass from intact cold leg to upper plenum is also modeled. The core

is modeled by 3 parallel channels; core bypass channel(volume 235) with 3 subvolumes,

average and hot core channel(volume 230 and 231) subdivided into 12 equally spaced

volumes respectively. It is assumed that the total mass flow rate through the core is

shared approximately 79%/a by the average channel, 16% by the hot channel and 5% by

5
core bypass channel. The heat generated in the fuel pin is transferred to primary coolant

by heat structures attached to the hot channel and the average channel. To include the

effect of heat capacity of material, heat structures of the downcomer and lower plenum

are modeled.

The intact loop consists of twenty volumes with several subvolumes. The pumping

system is divided into two pump lines with two individual pumps numbered as 135 and

165 respectively.

The ECC injection system consists of five volumes and one valve. This system is

connected to the intact loop cold leg volume modeled by the ECCMIX component(volume 185). The -PIS and LPIS are modeled by time dependent junctions numbered 635 and 625 respectively. Control valve(valve 610) in the accumulator line is to

isolate the accumulator when the accumulator is emptied.

The steam generator consists of eight volumes on the primary system and fifteen

volumes on the secondary system. Heat is exchanged between primary and secondary

side of the steam generator via the u-tubes which is modeled by heat structures. Feed

water system and steam condenser are modeled by time dependent volumes(volume 505

and 541, respectively). Feed water flow rate and steam flow rate are controlled by control logic to keep the required secondary pressure and level.

The pressurizer is modeled by surge line(volume 400 and 402), pressurizer vessel(volume 415) and pressurizer dome(volume 420). Pressurizer vessel was divided into

twelve subvolumes.

The broken loop hot leg is modeled by four volumes(volume 300 to 315). Component 315 represents steam generator simulator. The broken loop cold leg is modeled by 4

volumes(volume 335 to 344). Reflood assist bypass line is modeled by 2 volumes(volume

370 and 380). The reflood assist bypass valve is modeled by a trip valve which is closed

when the break valves are opened. At the end of each broken loop, two break valves

which have to be opened by trip signal are placed and connected with the suppression

6
tank modeled by two time dependent volumes(700 and 705). The discharge coefficients

of the break valves are 1.0 for the subcooled discharge and the saturated discharge.

In the input modeling delineated above, total number of hydrodynamic volumes,

junctions and heat structures are 147, 152, and 47, respectively.

3.2 Initial and Boundary Conditions

To obtain the initial conditions proper to the test conditions over the whole system,

a steady state calculation was performed with four steady state controllers and a time

dependent volume : two primary coolant pump speed controllers, a charging and letdown

controller, a feed water flow rate controller, and a time dependent volume to set pressurizer pressure to a designed value.

The results obtained from the steady state run were compared with the measured

initial conditions [4] in Table 2.1. The calculated results generally agree with the experimental conditions except the broken loop hot leg temperature which was estimated lower

than the measured data. The reason of such underprediction of the broken loop hot leg

temperature was not clear, but, it was believed to have negligible effect on the overall

system transient.

Based on the experiment data, the reactor power history, containment pressure

and feedwater flow rate after scram were described as time dependent tables. Performance curves for HPSI and LPSI flow rate as function of cold leg pressure were provided

in the input. The pump speed after trip was simulated by time dependent speed table.

And the steam generator secondary side air-cooled condenser was modeled as a time

dependent volume with a constant pressure of 2.069 MPa during the transient. All information of boundary conditions was provided in the steady and transient input deck.

7
4. RESULTS FROM BASE CASE CALCULATION

The LP-02-6 transient was calculated up to 80 secs from the initial conditions obtained from steady state run. Steady state controllers were deleted in the transient input

deck to get proper initial conditions.

The sequence of hydraulic events during the transient calculation was summarized

in Table 2.2 and compared with the experiment chronology. In general, the calculated

sequence of events show good agreement with the experiment, but, the overall transient

was calculated to progress more rapidly than the experiment because of rapid system

depressurization.

In this chapter, the predicted important thermal-hydraulic parameters such as system pressure, loop mass flow rates and cladding temperatures are compared with the

measured data. Table 4.1 summarizes the list of assessment parameters. It describes the

identification of calculated parameters and corresponding instruments in addition to uncertainties of measurements. The corresponding figure numbers are also listed in the table.

4.1 Loop Behavior

The behavior of calculated system pressure in the intact loop hot leg is plotted

with corresponding experimental data in Figure 4.1. It is easily found that the system

pressure was calculated to be lower than the measured data during overall transient. This

underestimation of system pressure might be a result of overprediction of break flow

during the blowdown, which will be discussed later.

The calculated mass flow rate in the broken loop cold leg and hot leg are shown in

Figure 4.2 and 4.3, respectively. As shown in the figures, the overall trends of mass flow

in the broken leg were predicted well. However, the peak values of the mass flow were

8
highly overestimated to be about 741 kg/sec (the measured value is -550 kg/sec) in the

cold leg and 241 kg/sec (the measured value is -193 kg/sec) in the hot leg. Such an

overprediction of mass flow rate in the broken loop in the early period of transient is

considered as a deficiency of RELAP5/MOD3.2 critical flow model. This might lead the

intact loop to contain less inventory than the experiment.

The calculated mass flow rates in the intact loop cold leg and the intact loop hot

leg were compared with the experimental data in Figure 4.4 and 4.5, respectively. It can

be found that the calculated mass flow rates followed the trend of the measured data very

well with slight underestimation of mass flow rate in the cold leg during the blowdown

phase.

The mass flow rate in the broken loop cold leg was predicted to fall below the

mass flow rate in the intact loop cold leg at -3.3 sees as shown in Figure 4.6. The fact

that the mass flow rate in the broken loop cold leg is lower than the mass flow rate in the

intact loop cold leg means that the flow in the broken loop cold leg is saturated and the

core is being filled with fluid from the intact loop cold leg. The phase transition of flow

in the broken loop cold leg was observed at -4 secs after transient initiation in the experiment.

4.2 ECCS Performance

Figure 4.7 shows the calculated accumulator pressure and Figure 4.8 shows the

predicted liquid level in the accumulator with corresponding measured data. As shown in

these figures, the accumulator injection was initiated at -14.5 secs while it was started at

17.5 secs in the experiment. This earlier accumulator injection was resulted from rapid

system depressurization.

Figure 4.9 shows the calculated LPSI mass flow rate with the measured data. The

injection was predicted to be earlier and higher than the measured data. This earlier and

9
higher injection was also due to the underestimation of the primary system pressure during the injection period.

4.3 Vessel Phenomena

Figure 4.10 shows the calculated liquid temperature in the lower plenum. The liquid temperature was underperdicted after -14 secs when the accumulator injection was

initiated -3 secs earlier than the experiment as stated in the previous section.

Figure 4.11 presents the collapsed liquid level in the two downcomer channels and

the two core channels of reactor vessel. Since no experiment data for these collapsed

liquid levels were available, the predicted levels are plotted only.

The liquid level in the core decreased rapidly after initiation of break and the core

was completely emptied at -3 secs until bottom up flow was initiated. The filling of the

core with the bottom up flow was predicted to make the lower part of the core rewet.

And then, the liquid level fell again below the bottom of core and was maintained low

level until the ECC injection water reached the bottom of core at -38 secs. The hot core

reflood was completed at 64 secs, -5 secs latter than the experiment.

In the early blowdown period up to -3 secs, the liquid level in the broken side

downcomer dropped more rapidly than that in the intact side one due to less flow resistance. The liquid level in the broken side downcomer increased for a short time from the

end of subcooled blowdown because the break flow was reduced significantly due to

saturation while the incoming flow from the intact loop cold leg was still maintained.

During the core rewetting period, the liquid levels in the both sides decreased again. The

decreasing rate of the broken side liquid level was smaller than that in intact side. This

was due to upward water flow from the lower plenum to the broken side downcomer.

The level in the intact side downcomer started to increase at -22 secs mainly due to accumulator injection flow initiated at 14.5 secs. The level in the broken side downcomer

10
also started to increase at -26 secs.

4.4 Fuel Thermal Response

Calculated cladding temperatures of hot rod at 12 axial hot core nodes are compared with the measured data of corresponding elevation in Figure 4.12 to Figure 4.23.

From the comparison of the cladding temperature behavior, following features are observed.

1) The blowdown heat up was relatively well predicted over the core except at the

highest node, but, it was calculated to occur little earlier than the measured data.

2) The blowdown heat up was underpredicted at the low heat flux region, and

overpredicted at the high heat flux region. In the middle part of the core, the

degree of overestimation is -60K at the hottest elevation.

3) The early bottom-up quenching was predicted to occur at the 1/4 lower part of

the core, while it was observed at the -2/3 lower part of the core in the experiment. Even more, it was calculated to be initiated slightly earlier than the measured data. This prediction of earlier and little amount of bottom up quenching

resulted from the overestimated peak mass flow rate in the broken loop cold leg,

i.e. cold leg break flow and the early end of subcooled blowdown as mentioned

in section 4.1.

4) The calculated second heat up was also calculated to start earlier than the

measured data due to earlier bottom-up quenching.

The peak cladding temperature(PCT) during the blowdown phase in the core was

calculated to occur at the elevation of 22 to 27.5 inches(node 5) while it was measured at

27 inches from the bottom of core. The calculated PCT is 1121 K, which is -50 K higher

I1
than that measured in the experiment. The calculated maximum cladding temperature

during the reflood phase was approximately 960 K while it was 831 K in the experiment.

Such an overestimation is a result from the deficiency of RELAP5/MOD3.2 not to be

able to predict the early bottom-up quenching in the middle part of the core.

5. SENSITVITY STUDIES

To investigate the influence of discharge coefficient on the resultant cladding temperature behaviors, two additional calculations were carried out. A brief note of these

calculations is as follows :

calculation ID subcooled discharge coeff. saturated discharge coeff.

DC1 1.1 1.1

(Base case) (1.0) (1.0)

DC2 0.9 0.9

And to find out the effects of the cross flow junction between the intact side

downcomer and the broken side downcomer, an additional calculation was performed

with six cross flow junctions between all the volumes of both sides. The sum of mass

flow through the cross flow junctions before the initiation of transient in the calculation

is made to be nearly equal to that in the base case calculation by adjusting the energy loss

coefficients of junctions. For the convenience of later discussion, the calculation was

named SIXX.

Finally, a calculation using RELAPS/MOD3.1 was conducted to identify the effects of improved features of RELAP5/MOD3.2 for the LBLOCA analysis.

5.1 Influence of Discharge Coefficient

In Figure 5.1 and 5.2, the calculated mass flow rates in the broken loop cold leg

and hot leg with various discharge coefficients are presented for comparison. These figures show that the mass flow rate in each broken leg during the blowdown is highly de13
pendent on the discharge coefficient.

Figure 5.3 contains the difference between mass flow rate in the intact loop cold

leg and mass flow rate in the broken loop cold leg, and Figure 5.4 presents the calculated

bottom-up core mass flux at the hot core inlet junction induced by the mass flow difference. From these figures, it can be found that the bottom-up core flow in the blowdown

phase is dominated by the discharge coefficient at the break and the smaller discharge

coefficient, in other words, the lower break flow induces the higher bottom-up core flow.

This correlation between the discharge coefficient and the bottom-up core flow

can be made clear by Figure 5.5 and 5.6, which show the calculated cladding temperature

behaviors at the hot core node 5 and 8, respectively. As shown in the figures, the more

break flow rate was estimated in the blowdown phase, the less bottom-up quenching was

predicted.

5.2 Influence of Cross Flow Modeling in the Downcomer

Figure 5.7 contains the calculated downcomer liquid levels both in the base case

calculation and in the SIXX calculation. From the figure, one can find that the liquid levels of both sides of downcomer predicted in the calculations showed almost similar trend.

The difference between the base case and SIXX calculation for the core bottom-up

flow is shown in Figure 5.8 As shown in the figure, the initiation and completion of bottom-up flow in the SIXX calculation was predicted to be little later than those in the base

case, and the total bottom-up flow in the SIXX calculation is considered somewhat

greater than that calculated in the base case calculation. Such a delayed and larger bottom-up flow resulted in lower and delayed second heat up.

Figure 5.9 shows the mass flux at the outlet of the core. The calculated top-down

quenching flow in the base case was higher than that predicted in the SDCX calculation.

14
However, the cladding temperature behavior predicted in the both calculations didn't

show any significant difference because the differences of flow behavior were not so

large. The cladding temperature behaviors at hot core node 1, 5, and 10 are presented in

Figure 5.10 to 5.12.

In conclusion, the hydraulic and thermal behavior in the core calculated by

RELAP5/MOD3.2 was not strongly dependent on the number and position of the cross

flow junctions in the downcomer.

5.3 Calculation Using RELAP5/MOD3.1

A calculation similar to the base case using RELAP5/MOD3.1, for which we

didn't make any change after it was received at October in 1993 from USNRC , was

performed to identify the difference between RELAP5/MOD3.1 and RELAP5/MOD3.2

for LBLOCA analysis.

The calculated hydraulic behavior by RELAP5/MOD3.1 is very similar to that

predicted by RELAP5/MOD3.2. The mass flow rates in the broken loop cold leg and hot

leg, for instance, showed nearly same trend as shown in Figure 5.13 and Figure 5.14.

However, the cladding temperatures predicted by RELAP5/MOD3.1 showed less degree

of heat up both in the blowdown phase and the reflood phase than those by

RELAP5/MOD3.2. The cladding temperatures calculated by RELAP5/MOD3.1 at several elevations are presented in Figure 5.15 to Figure 5.17 with corresponding data by

RELAP5/MOD3.2. More profound studies of these results were not tried because the

predicted cladding temperature behavior by RELAP5/MOD3.1 and RELAP5/MOD3.2

showed no dramatic difference.

6. RUN STATISTICS

The computer used in the present calculations was HP9000/K200 workstation at

KNFC, with OS Version 10.01.

Figure 6.1 presents the plot of the required CPU time for the transient time in the

base case calculation. And the time step sizes are also plotted in Figure 6.2. The userspecified maximum time step was 0.01 sec up to 30 secs in real time and then reduced to

0.002 sec up to 80 secs. The run statistics from the major edit is summarized in Table 6.1

and the grind time can be calculated as follows.

Computer time, CPU = 2397.7 - 1 = 2396.7

Number of time step, DT = 28615 - 167 = 28448

Number of volume, C = 147

Transient real time, RT = 80 (secs)

Grind time = CPU x 1000/(C xD7) = 0.573 CPUm sec/vol/step

6. CONCLUSIONS AND RECOMMENDATIONS

RELAP5/MOD3 code was assessed using LOFT LP-02-6 test data. A base case

calculation using RELAP5/MOD3.2 was carried out as a reference case. Discharge coefficient sensitivity studies were performed to investigate the influence of this user-specific

parameter in the analysis of LBLOCA. A more detailed modeling of cross flow in the

inlet annulus and downcomer volume was tried to improve the code predictability of

early bottom-up quenching in the blowdown phase. As a final case, a calculation using

RELAP5/MOD3.1 was performed to identify the differences between RELAP5/MOD3.1

and RELAP5/MOD3.2. Based upon the results from the scope of this study, the following conclusions were made.

1) Using LOFT LBLOCA test data LP-02-6, a base calculation with a standard

nodalization was successfully performed and matched relatively well with the

experimental data.

2) RELAP5/MOD3.2 with standard nodalization can predict system hydraulic behavior. However the mass flow rates in the broken loop cold leg and hot leg

during the subcooled blowdown were largely overestimated.

3) RELAP5/MOD3.2 can predict well the blowdown heat up of the core. However, the calculated blowdown heat up was initiated slightly earlier than the experiment due to the poor prediction of heat transfer in the fuel rod during blowdown. The calculated PCT was predicted to be -50K higher than the measured

data.

4) The bottom-up quenching in the middle part of hot core was not predicted

17
properly by RELAP5/MOD3.2, therefore, the maximum cladding temperature

during the reflood phase was highly overestimated to be about 960 K.

5) RELAP5/MOD3.2 was so sensitive to the discharge coefficient that the resultant behavior of cladding temperatures was greatly varied with small change of

discharge coefficient. The development of more accurate break flow model,

which is known to be undergoing, should be made to remove the sensitiveness

to this user accessible parameter.

6) From our analysis of cross flow modeling in the downcomer volume, it was revealed that the core flow behavior is not dependent on the position and number

of cross flow junctions connected. In other words, single cross flow junction

with a low energy loss coefficient and multiple cross flow junctions with a high

energy loss coefficient might have similar effect on the resultant thermal behavior in the core.

7) Neither of code versions, RELAP5/MOD3.1 and RELAP5/MOD3.2, could

predict properly the early bottom-up quenching in the middle part of the core.

The only effect of improved features of RELAP5/MOD3.2 could be shown in

the lower part of core, where RELAP5/MOD3.2 could predict the blowdown

heat up better than RELAP5/MOD3.1.

8) It was revealed that RELAP5/MOD3 can be used as a best estimate tool for

analysis of LBLOCA with the improvement of break flow model which has

great influence on the predictability of early bottom-up quenching in the

LBLOCA.

11. ABSTRACT r2"O words r ksw)

The LOFT experiment LP-02-6 was simulated using the RELAP5/MOD3.2 code to assess its capability to predict the

thermal-hydraulic phenomena in LBLOCA of the PWR. The reactor vessel was modeled with two core channels and split

downcomer for a base calculation. The results of the base calculation show that the code can not predict the early bottom-up

quenching which is a distinguished phenomenon of the experiment LP-02-6, mainly due to the deficiency of break flow model.

The discharge coefficient sensitivity study was performed to show that the calculated subcooled break flow which might significantly

affect the early bottom-up quenching is dependent on the coefficient More detailed modeling of the cross flow In the splt

downcomer was performed, but, resulted in little improvement on the predictability of bottom-up quenching. Additional calculation

using the RELAP5/MOD3.1 instead of RELAP5/MOD3.2 showed that there is no large difference between the versions in the

simulation of LBLOCA.
