RELAP5 ASSESSMENT USING LSTF TEST DATA SB-CL-18

Abstract

5 % cold leg break test, run SB-CL-18, conducted at the Large Scale

Test Facility (LSTF) was analyzed using the RELAP5/MOD2 Cycle 36.04 and

the RELAP5/MOD3 Version 5m5 codes.

The test SB-CL-18 was conducted with the main objective being the

investigation of the thermal-hydraulic mechanisms responsible for the

early core uncovery, including the manometric effect due to an asymmetric

coolant holdup in the steam generator upflow and downflow side.

The present analysis, carried out with the RELAP5/MODZ and MOD3

codes, demonstrates the code's capability to predict, with sufficient

accuracy, the main phenomena occuring in the depressurization transient,

both from a qualitative and quantitative point of view. Nevertheless,

several differences regarding the evolution of phenomena and affecting

the timing order have to be pointed out in the base calculations.

The sensitivity study on the break flow and the nodalization study

in the components of the steam generator U-tubes and the cross-over legs

were also carried out. The RELAP5/MOD3 calculation with the nodalization

change resulted in good predictions of the major thermal-hydraulic

phenomena and their timing order.

Executive Summary

The LSTF test SB-CL-18 has been analyzed using the RELAP5/MODZ and

MOD3 codes to assess the code's ability for a 5 % cold leg break LOCA, to

improve common understanding of PWR thermal-haydraulic response during

such a transient and to identify areas for desirable model improvements

based on comparisons between data and predictions.

The main goal of the calculation is the assessment of the simulation

capability of the code for the following phenomena occurring during the

small break LOCA experimental test;

- top-down drain of coolant in primary system

- stratified two-phase flow in horizontal legs

• loop seal clearing and concurrently temporary core liquid

depression, with influenced residual liquid holdup in steam

generator primary side, leading to core heatup

- quick core level recovery after loop seal clearing

- vessel inventory boil-off leading to second core uncovery

0 core reflooding due to accumulator injection.

The calculated overall trend agreed well with the test data.

However, several differences regarding the evolution of phenomena and

affecting the timing order have to be point out.

In the base calculation with the RELAP5/NOD2, one can observe three

fundamental disagreements between calculated and experimental transient

V
sequences. The first is the underestimation of the calculated two-phase

break flow rate (between 100 and 200 seconds) leading to an insufficient

mass discharge from the primary system and therefore from the pressure

vessel. A sensitivity study on the break flow rate using break flow

options, i.e., abrupt area change and smooth area change, and break

cischarge coefficients of two-phase flow, was carried out. However the

results did not give sufficient improvement on predicting the break flow

rate. The second and the most important inaccuracy is that the code

strongly overestimates the liquid holdup in the upflow side of the steam

generator U-tubes, giving rise to a plug effect hindering the loop seal

downflow side level decreasing and delaying the loop seal clearance. The

third discrepancy of the calculation in comparison with the experiment is

that the higher vapor-phase break flow rate after 160 seconds results in

a fast primary mass loss and therefore in an anticipated earlier

accumulator injection.

In the base calculation with the RELAP5/MOD3, the first and the

third disagreements described above were still observed. The liquid

holdup in the upflow side of the steam generator U-tubes was predicted

well with the experiment, however the complete loop seal clearing was not

occurred throughout the transient. This discrepancy was cleared by the

nodalization changes in the steam generator U-tubes and the cross-over

legs and the calculated results were in good agreement with the

experiment in the evolution of the major thermal-hydraulic phenomena and

their timing order.

1. Introduction

The International Code Assessment and Application Program (ICAP) has

been conducted by fourteen nations and multinational organizations under

the auspices of the USNRC[1]. For the pressurized water reactor

analysis, the USNRC selected two best estimate (BE) codes: RELAP5/IOD2

and TRAC/PFl/MODl[2]. The goal of the program is to assess the

prediction capabilities of the current BE thermal hydraulic codes

utilizing the available facility test and plant data. At present the

ICAP activities in Korea help to quantify uncertainties in the codes so

that the codes may be used for regulatory purposes.

This report is a part of the Korean contribution to the ICAP. The

RELAP5/MOD2[3] Cycle 36.04 and the RELAP5/MOD3[4] Version 5m5 were used

in the present calculations simulating the test SB-CL-18 of the Large

Scale Test Facility (LSTF) [5].

The Rig of Safety Assessment No. 4 (ROSA-IV) Program, launched by

the Japan Atomic Energy Research Institute (JAERI) in 1980 immediately

after the Three Mile Island Unit 2 accident, comprises three major tasks:

(1) conducting integral effect tests on PWR small break loss of coolant

accidents (SBLOCAs) and transients using the LSTF, (2) conducting

separate effects tests using the Two-Phase Flow Test Facility (TPTF), and

(3) developing and verifying an advanced thermal-hydraulic code for the

analysis of SBLOCAs and transients.

The test SB-CL-18[6], as one of the Integral Effect Test (IET), was

1
simulated 5 % cold leg break (loop without pressurizer) test and

conducted with the main objective being the investigation of the

thermal-hydraulic mechanisms responsible for the early core uncovery,

including the manometric effect due to an asymmetric coolant holdup in

the steam generator (SG) upflow and downflow side.

The main goal of the calculation is the assessment of the simulation

capability of the code for the following phenomena occuring during the

small break LOCA experimental test;

- top-down drain of coolant in primary system

- stratified two-phase flow in horizontal legs

- loop seal clearing and concurrently temporary core liquid

depression, with influenced residual liquid holdup in SG primary

side, leading to core heatup

- quick core level recovery after loop seal clearing

- vessel inventory boil-off leading to second core uncovery

- core reflooding due to accumulator injection.

The report describes the results of the calculation performed by the

RELAP5/NOD2 and MOD3 codes and shows the comparisons with the major

variables obtained in the experiment. A brief description of the LSTF

and SB-CL-1i test is provided in Section 2, and Section 3 describes the

features of the RELAP5 code and modelling to be assessed. Section 4

discusses the results of the base calculations with the RELAP5/IOD2 and

MOD3. The motivations for the sensitivity and nodalization studies and

2
their results are included in Section 5. The code efficiency is

evaluated in Section 6 through run statistics. The conclusions drawn

from this study are given in Section 7.

2. Facility and Test Description

2.1 Facility Description

The LSTF [5) is a 1/48 volumetrically scaled model of a Westinghouse

type 3423 MfWt four loop Pressurized Water Reactor (PWR). The LSTF has

the same major component elevations as the reference PWR to simulate the

natural circulation phenomena and large loop pipes (hot and cold legs of

207 mm in diameter) to simulate the two-phase flow regimes and

significant phenomena in an actual plant. Fig. 1 and Table 1 show the

structure and major dimensions of the LSTF, respectively. The facility

is designed.to be operated at the same high pressures and temperatures as

the reference PWR.

The LSTF facility simulates the major components of the PWR primary

system (e.g., pressure vessel, steam generators) and the reactor

protection system (e.g., emergency core cooling system, ECCS) that have

an impact on the plant behaviour during SBLOCAs and operational

transients. 'Equipment controls allow the test operators to either follow

procedures defined in standard plant manual br to follow variations of

standard procedures.

Other systems, such as the secondary and various auxiliary systems,

are capable of achieving pretest steady-state conditions and simulating

the primary to secondary interactions. These systems include feedwater,

condensate and steam systems together with component service systems such

4
as the cooling water, water purification etc.

The fuel assembly dimensions [7], i.e. the fuel rod and the guide

thimble diameter, pitch and length, and the ratio of number of fuel rods

to number of guide thimbles are designed to be the same as the 17 x 17

fuel assembly of the reference PWR to preserve the heat transfer

characteristics of the core. The total number of rod is scaled by 1/48

and is 1064 for the electrically heated and 104 for the unheated rods.

The downcomer, lower plenum and upper plenum design, including the

scaled internal structures, maintains, to a practicable extent, the

volume and flow resistances typical of the reference PWR.

Three core bypasses, consisting of the downcomer to hot leg leakage,

an unintentional leakage between the downcomer and the upper plenum, and

the spray nozzle connecting the downcomer to the upper head, are also

simulated.

The most important design scaling compromise is the 10 MW maximum

core power limitation, 14 % of the scaled reference PWR rated power. The

steady state condition is therefore restricted to a core mass flow rate

that is 14 % of the scaled value, to simulate the reference PWR

temperature distribution in the primary loop.

The steam generators are designed in accordance with the facility

scaling requirements, also in consideration that the rated 10 IlWt LSTF

power capability sets the steady-state flow conditions at 14 % of the

scaled reference PWR SG-flow.

The four primary loops of the reference PWRs are represented by two

equal-volume loops. The hot and cold legs were sized to conserve the

5
volume scaling and the ratio of the length to the square root of the pipe

diameter, L/ rD for the reference PWR, in expectation that the flow

regime transitions in the primary loops can be simulated appropriately by

taking this scaling approach.

A simulated containment system is available to collect and contain

the effuent from simulated breaks. The simulated containment system is

designed to ensure that the break flow will always be choked.

2.2 Test Description

The test SB-CL-18 was simulated 5 % cold leg horizontal break and

the break point is located in the B-loop (loop without pressurizer) cold

leg, between the reactor coolant pump and the reactor pressure vessel,

with horizontal nozzle orientation. The test procedures were designed to

minimize the effects of LSTF scaling compromises on the transients during

the test.

After the break occurs at time zero, the primary system

depressurizes quickly. During the first few seconds from the time of

break onwards, the pump's speed is intentionally increased to simulate

the post-scram hot leg temperature decay in PWR. At a pressurizer

pressure of 12.97 MPa the reactor scrams. Since the loss of offsite

power concurrent with the reactor scram is assumed, the primary coolant

pumps are tripped to begin coastdown and the core power begins to

decrease along the programmed decay curve. The power decay used in the

test gives a slower decrease than the ANS standard.

6
The major operational setpoints and EGCS conditions are summarized

in Table 2. To simplify the transient it is assumed that the SG

auxiliary feedwater system as well as the high pressure charging system

and the High Pressure Safety Injection (HPSI) system fail. As a result

of the station blackout, concurrent with the auxiliary feedwater failure,

the SG secondary side is isolated, allowing, in any case, the steam

discharge through the relief valves (cycling between opening and

closure). The Accumulator (ACC) system and the Low Pressure Safety

Injection (LPSI) system are specified to initiate coolant injection into

the primary system at pressures of 4.51 and 1.29 MPa, respectively.

7
3. Code and Nodelling Description

3.1 Code Description

The RELAP5/MOD2 code has been developed for best-estimate transient

simulation of PWRs and associated systems. The code is based on a

non-homogeneous and non-equilibrium model for one dimensional, two-phase

system that is solved by a fast, partially implicit numerical scheme to

permit economical evaluation of system transients. Recently, the

RELAP5/MOD3 code development program has been initiated to develop a code

version suitable for the analysis of all transients and postulated

accidents in PWR systems including both large and small break LOCAs as

well as the full range of operational transients. Although the emphasis

of the RELAP5/1OD3 development is on large break LOCA, improvements to

existing code models, based on the results of assessments against small

break LOCA and operational transient test data, are also being made.

Table 3 is a list of the phenomena and code models,improved from the

RELAP5/MOD2, that are being addressed by the RELAP5/MOD3 code program.

The RELAP5/MOD2 Cycle 36.04 and the RELAP5/1OD3 Version 5m5 were

used in this assessment.

8
3.2 Modelling Description

The nodalization used to simulate the LSTF facility of the ROSA-IV

program with the RELAP5 code is shown in Fig. 2. The model is based on

162 volumes connected by 169 junctions and 166 heat structures.

In the reactor vessel element (volumes 100 to 156) the volumes

corresponding to the downcomer, the lower plenum, the core, the upper

plenum, the upper head and the guide timble channel are defined. In the

schematization of the upper part of the LSTF downcomer (volumes 100 and

104), care was taken to correctly simulate the steady-state mass flow

rates in the connections with the hot legs (bypasses), the upper plenum

(unintentional leak path) and the upper head (spray nozzles) to obtain

the requested values, i.e. 0.1 %,0.085 % and 0.3 % of the core inlet

flow rate, respectively. The core is modelled by one channel arranged in

6 hydraulic volumes, in which only one series of heat -structures is

adopted to simulate the fuel assembly (i.e. a flat radial core power

profile is assumed). The reason for this choice resides in the attempt

to perform the simplest modelling of the LSTF facility as possible.

A pipe connection (volume 156) between the upper head and the upper

plenum of the pressure vessel is introduced in the scheme to simulate the

guide thimble channel path existing in the facility. The two loops of

the LSTF system are represented by the I-loop (volumes 400 to 499, intact

loop) and the B-loop (volumes 200 to 299, broken loop) in an almost

symmetrical way. In fact, each of the two loops present the hot leg, the

SG inlet and outlet plena, the SG U-tube channel, the loop seal, the

9
reactor coolant pump, the cold leg. In addition, the pressurizer is

connected to the I-loop hot leg by means of the surge line element and

the break system is connected to the B-loop cold leg.

In the volumes representing the pressurizer vessel, an additional

heat structure is introduced to simulate the effects of the proportional

and back-up heaters.

The two steam generator secondary sides (volumes 300 to 399 and 500

to 599) are simulated using an identical schematization. They can be

subdivided into the downcomer, the boiling section, the steam separator

and the steam dome. The steam and feedwater lines are simulated by using

Time Dependent Junctions (i.e. with imposed flow rates) because they

must be excluded during the transient-phase of the calculation. In fact,

in the experimental test, the two mentioned lines are closed in

coincidence with the reactor scram signal, few seconds after break

opening, to isolate the SG secondary side. Relief and safety valves are

also connected to the SG steam dome using valve components in which the

operational setpoints and conditions are specified to be the same as the

experiment.

The requested volume distributions for the primary and secondary

system, including the "active dead volumes" distribution, is taken into

account for the determination of the piping cross sectional areas, that

result in small area differences between analogous pipes belonging to the

two different loops.

The nodalization of the SG secondary side (volumes 328, 332, 528,

532 and 800 to 820) is simulated for the present case, however it could

10
have been reduced to be simpler.

The steam generators as well as the pressurizer are provided with

two systems devoted to the control of the pressure and the liquid level

during the steady-state period (200 sec.) and to maintain them at the

specified initial values.

The physical boundaries of the entire system, i.e., the reactor

containment and the relief and safety discharge tanks, are reproduced by

means of Time Dependent Volumes with constant internal conditions during

the calculation.

To allow the accumulator injection to start correspondingly to the

cold leg pressure specified in the experiment, a valve is arranged on

each of the accumulator surge lines.

The choked flow option is specified in the valve simulating the

break and to avoid the code calculating mass flow rates to be

inconsistent with the experimental data, the subcooled and two-phase

discharge coefficient are chosen as close as 1.0 and 1.05, respectively.

11
4. Base Calculations

During a small break loss of coolant accident,the primary coolant

inventory loss will continue until the break flow rate decreases

sufficiently, due to break uncovery or primary depressurization, to allow

the emergency core cooling system to make up the coolant loss. Such

coolant inventory depletion will involve concurrent liquid level

depressions in the downflow side of. the cross-over leg , for each loop,

and in the vessel riser section (upper plenum and core). Meanwhile, the

upflow side of the cross-over leg, cold leg and downcomer will remain

liquid filled up to the break elevation. The core level depressions will

continue until the level of the downflow side in the cross-over leg

reaches the bottom of the legs and thus allows the vapor to clear the

liquid seal in the cross-over legs toward the break. When this liquid

clearing (loop seal clearing) initiates, the core liquid level starts to

recover. This occurs because the vapor can now reach to the downcomer

and allows a manometric flow of the downcomer liquid inventory into the

core region[8J.

In the present study both the RELAP5/MOD2 and OND3 codes were used

for the base calculations and their results are shown in the figures from

3 to 44. In all figures, the results with the RELAP5/1OD2 and with the

RELAP5/MOD3 are represented as "Calculated 1 " and "Calculated 2 ,"

respectively.

The major initial conditions, as shown in Table 4, and the sequence
of events, summarized in Table 5, are compared with the experiment. The

input listing for the base calculation with the RELAP%/MOD3 is attached

in Appendix.

4.1 RELAP5/MOD2

The calculated results for the principal events are compared with

the experimental values in'Table 5. All the main primary phenomena

observed during the experiment were reproduced by the code.

i) Primary and Secondary Pressures Response

Figures 3 to 5 show the primary and secondary pressure in comparison

with the experimental values. The code predicts well the secondary

pressure trend, whereas, despite a good qualitative agreement, it

highlights some differences in the behavior of the primary

depressurization in the region between 200 and 600 seconds.

The primary pressure depressurization became slower after flashing

started in the primary loop hot side. The primary pressure remained

higher than the secondary pressure until after the loop seals cleared

completely.

In this respect one should point out the strong delay at which the

loop seal clearance occur in comparison with the experiment as shown in

Figs. 6 to 9. This occurrence results in a delayed beginning of the

linear primary pressure decrease, happening moreover with a higher

depressurization rate. The mentioned faster pressure decreasing allows

13
an earlier intervention of the accumulator system as shown in Figs. 10

and 11.

ii) Break Flow Rate

Figs. 12 and 13 show that the break flow rate is first

overpredicted by about 30 % for subcooled liquid discharge and is

underpredicted as approaching saturation condition. In the region

between 50 and 150 seconds, the two-phase break flow rate is definitely

underestimated by the code, in such a way that the time integrated mass

inventory, escaping from the break in that period, is about one half of

the experimental value. The underprediction of liquid and low-quality

two-phase break flow rates resulted in a delay of loop seal clearing

relative to the experimental result. Loop seal clearing occurred at 195

seconds (vs. 140 seconds in the experiment). Both loop seal cleared at

the same time as was the case in the experiment.

iii) SG U-tube differential Pressure

Figures 6 to 9 show the differential pressures in SG U-tubes, upflow

and downflow side. The agreement between measured and calculated data is

acceptable concerning the downflow side, but the code predicts too strong

liquid holdup in the upflow side of the SG U-tubes. This SG liquid

holdup was overpredicted tending to enhance the core level depression

during loop seal clearing. While considerable amount of liquid remained

in the upflow side of the SG U-Tube and SG inlet plenum at the time of

loop seal clearing, the hot legs underneath were nearly empty after 130

14
seconds.

The SG U-tube differential pressure as shown in Fig. 14 increased

until it took a maximum of 18 kPa at about 140 seconds. This increase

resulted from a redistribution of liquid due to the hydrostatic pressure

balance throughout the primary system during flow coastdown. During the

flow coastdown, the pressure distribution in the primary loops changed

since frictional pressure losses (mainly at the pumps) decreases and the

core void fractions increased. At 120 seconds, the vertical legs in the

cold side loop was liquid filled whereas the hot side loop contained much

void as shown in Figs 15, 16 and 17. Thus, due to the manometric balance

between the hot side loop and the cold side loop, including the SGs, more.

liquid was retained in the SO upflow side than in the downflow side. The

calculation overpredicted the peak SG differential pressure, that was

reached at the end of two-phase natural circulation.

The SG liquid holdup persisted after loop seal clearing in this

calculation. The differential pressure in the SO inlet plenum became

zero at 300 seconds (vs. 300 seconds in the experiment) as shown in

Figs. 18 and 19. Also the differential pressure in the upflow side of

the SO U-tube increased after loop seal clearing while such an increase

was not seen or less significant in the experiment. Thus, the liquid

level recovery into the upper plenum and hot legs after loop seal

clearing was underpredicted or not predicted at all as shown in Fig. 20.

Consequently, the second core level drop initiated 320 seconds (vs. 400

seconds in the experiment), i.e., immediately after the level recovery

following loop seal clearing.

15
iv) Core Thermal-Hydraulic Responses

The differential pressures in the core and the upper plenum are

presented in Fig. 21 in which the code achieves a good simulation of the

core level depression. One can observe, however, that the first core

uncovery and consequent recovery is delayed about 50 seconds, whereas the

second core level depression is anticipated earlier about 60 seconds.

The reason for this behavior resides in the simultaneous occurrence of

several effects. The duration of the first core heatup, associated with

loop seal clearing, was overpredicted because of the underprediction of

the core liquid level. The reason for the early second core uncovery

must be given to the faster linear depressurization predicted by the

calculation after loop seal clearing, causing the anticipated vessel mass

inventory boil-off.

The core level was depressed manometrically, concurrently with the

level drop in cross-over legs, and took a minimum immediately before the

loop seal clearing started. This minimum core level was lower than the

cross-over leg liquid level which was at the bottom of the leg.

The core inlet flow almost stopped after 150 seconds as shown in

Fig. 22. After this, the core was covered by nearly stagnant two-phase

mixture until core uncovery started at about 170 seconds.

Figs. 23 and 24 show rod surface temperature at the average-power

bundles. The core liquid level depression resulted in rod temperature

excursions starting from about 150 seconds. The peak cladding

temperature was about 750 K (vs. 680 K in the experiment) for the

average-powered bundles. After the loop seal clearing, the core liquid

16
level recovered quickly and heater rods were quenched as shown in Fig.

20. The core differential pressure was generally underpredicted. This

was the case even when the core was covered by two-phase mixture. This

occurred due to an overprediction of core interfacial drag; a well-known

deficiency of the RELAP5/MOD2 interfacial drag models.

v) Transient Behavior of Other Variables

The transient behavior of the other variables are shown in Figs. 25

to 44. The variables, such as flow rates, liquid densities, and fluid

temperatures in the primary loops, etc., were in good agreement with the

experiment. However large fluction of the fluid temperatures in the cold

legs of the primary loops was occurred after the accumulator injection.

17
4.2 Base Calculation with RELAP5/NOD3

The modifications to the RELAP5/MOD2 input deck to accommodate the

RELAP5/MOD3 are as follows:

- Countercurrent and Flow Limiting (CCFL) options added at the inlet

to the steam generator U-tubes and the 40 degree bend in the hot leg

- Junctions in the core region modified for new interphase drag package

(flow area and hydraulic diameters)

- Heat structure cards added for new Critical Heat Flux (CHF)

calculation

The calculated results for the principal variables are compared with

the experimental values in Table 5.

The trend in the break flow rate is almost same as that with the

RELAP5/MOD2. Therefore, in the region between 50 and 150 seconds the

two-phase break flow rate is still underestimated as shown in Figs. 12

and 13. Nevertheless, the integrated break flow shows nearly identical

to the experiment. Therefore it may be considered that there exists some

errors in measuring break flow rate. And the break flow rate with high

void fraction was overpredicted after 200 seconds as shown in Fig. 13.

The primary pressure decreases nearly same as test data up 250 seconds,

however the faster decrease in the pressure after 250 seconds allows an

earlier intervention of the accumulator injection as shown in Fig. 10.

It is shown in the figures 6 to 9 that the strong liquid holdup in

18
the SG upflow side is not occurred unlikely the case with the

RELAP5/MOD2. This improvement may be obtained from the implementation of

the new interphase drag model in the RELAP5/MOD3. The calculation

overpredicted the peak SG differential pressure, that was reached at the

end of two-phase natural circulation as shown in Fig. 14.

The significant difference is found in the loop seal clearing

phenomena as shown in Figs. 15 and 16. The loop seal clearing was

started at 150 seconds, however, was not cleared completely through the

transient.

The liquid level and the differential pressure in the heated core

length are shown in Figs. 20 and 21, respectively. The first core

uncovery is occurred at 100 seconds which is earlier than the experiment

of 120 seconds and the duration of the first core heatup is nearly same

as the experiment even though the core level depression was

overpredicted. The second core level drop initiated 165 seconds (vs.

400 seconds in the experiment), i.e., immediately after the level

recovery following the loop seal clearing as shown in Fig. 20.

The transient behavior of the other variables are shown in Figs. 22

to 44. The variables, such as flow rates, liquid densities, and fluid

temperatures in the primary loops, etc., were in good agreement with the

experiment. However large fluctions of the fluid temperatures and liquid

densities in the cold legs of the primary loops were occurred after the

accumulator injection.

The major areas of the differences between the RELAP5/MOD2 and the

RELAP5/MOD3 are the primary system pressure response, the differential

19
pressure in the upper plenum, core heatup prediction, core liquid level

depression, and the drainage of steam generator inlet plena. These

differences may be due to modifications to interphase drag model which

affected the liquid holdup in the upper plenum and void distributions in

the primary loops. Both calculations predicted trend well, however each

differed in prediction of the magnitude and timing of occurrences. In

the RELAP5/MOD3 calculations the amount of liquid holdup in the upflow

side of the SG U-tubes predicted well, however the complete loop seal

clearing was not occurred throughout the transient, which was occurred in

the experiment.

20
5. Sensitivity and Nodalization Studies

The base calculations agreed well with the test data. However the

break flow rates and the timing order of the principal phenomena have to

be pointed out.

5.1 Break Flows

From the discussions in the previous chapters, it was found that the

break flow was overestimated about 30 % at the initiation of the

transient and was underpredicted in the region between 50 and 150

seconds. Thus it may be necessary to predict the thermal-hydraulic

transient phenomena more accurately by considering the break flow

options, i.e., abrupt area change and smooth area change, and break

discharge coefficients for the single- and two-phase flows.

In the present calculation with the RELAP5/MOD2, several values of

the two phase break discharge coefficients with both abrupt and smooth

area change options. For single phase flow, a discharge coefficient was

fixed to be 1.0 here.

Figs. 45 to 50 show the effect of two phase break discharge

coefficient with both area change options. With the abrupt area change

option, the break flow rate was still underestimated in the region

between 50 and 150 seconds and the little differences were found for

different discharge coefficients. With the smooth area change option,

21
similar underprediction of break flow was obtained, however it matched

better with the experiment in the single phase region, particularly in

the region between 50 and 100 seconds.

5.2 Nodalization

In the calculation with the RELAP5/MOD3 the complete loop seal

clearing was not occurred, therefore the nodalization study may be

necessary to evaluate the effectiveness of the nodalization and to

quantify their effects on the loop seal behavior, particularly on the

loops from steam generator inlet to reactor coolant pump inlet via the

cross-over cold legs. In this calculation with the RELAP5/MOD3 the

volumes, stated above, were divided twice than the base case to show the

effect of loop seal clearing and related phenomena. This model is based

on 204 volumes connected by 211 junctions and 216 heat structures.

The calculated results for the principal variables are compared with

the experiment and the base calculation with the RELAP5/1OD3 results in

Table 4. The base calculation and the calculation with nodalization

change are represented as "Calculated 2" and "Calculated 3 ",

respectively, in Figs. 51 to 70.

The calculated results of the break flow rate, the primary and

secondary pressures show almost same trend as those with the RELAP5/MOD3

as shown in Figs. 51 and 55. In Figs. 56 to 57 the differential

pressure of the cross-over leg predicts much better than the base

calculation with the RELAP5/MOD3 which did not show the complete loop
seal clearing. The liquid in the downflow side of the cross-over leg is

empted after the loop seal clearing, however some liquid in the upflow

side of the cross-over leg existed throughout the transient.

The timing order of the first core uncovery and the duration of the

core heatup is predicted remarkably well with the experiment, however the

liquid level depression is still underpredicted and the quick second core

level depression was also occurred as shown in Figs. 58 and 59.

23
6. Run Statistics

CDC 170-875 Series with NOS Version 2.6.1 for calculation using

RELPP5/MOD2 Code and CRAY2S/4-128 for calculation using RELAP5/MOD3 Code

were used.

Fig. 71 shows the required CPU time vs the transient time in the

base calculations. The size of the time step was chosen to be 10E-6 and

1OE-1 seconds at the minimum and the maximum time step, respectively, for

both base calculations. During the RELPP5/MOD3 calculation the water

property errors were occurred about at 100, 190, and 320 seconds.

Therefore, restart calculation with reduced time step of 0.05 seconds

were applied for the next 30 seconds to overcome this. The computational

efficiency is summarized in Table 7 from the major edit for base

calculations and can be calculated as follows.

(CPU),sec Step (DT), Volume (N) CPU/(N*DT)

RELAP5/MOD2 2351.7 6376 162 0.002276

RELAP5/MOD3 1865.2 15338 162 0.001153

7. Conclusions

The LSTF test SB-CL-18, 5 % cold leg break LOCA, was analyzed using

the RELAP5/MOD2 and NOD3 codes. Four major calculations were carried

out; two base calculations with the RELAP5/MOD2 and NOD3, one

sensitivity calculation with the RELAP5/MOD2 using the break flow

options, and one nodalization study with the RELAP5/MOD3 in the areas of

the SG U-tubes and the cross-over legs.

The present activity demonstrates the code's capability to predict,

with sufficient accuracy, the main phenomena occurring in the

depressurization transient, both from a qualitative and quantitative

point of view. In the base cases, several differences regarding the

evolution of such phenomena and affecting their timing order have to be

pointed out.

In the base calculation with the RELAP5/MODZ, one can observe three

fundamental disagreements between calculated and experimental transient

sequences. The first is the underestimation of the calculated two-phase

break flow rate (between 100 and 200 seconds) leading to an insufficient

mass discharge from the primary system and therefore from the pressure

vessel. A sensitivity study on the break flow rate using break flow

options was carried out. However the results did not give sufficient

improvement on predicting the break flow rate. The second and the most

important inaccuracy is that the code strongly overestimates the liquid

holdup in the upflow side of the SG U-tubes, giving rise to a plug effect

25
hindering the loop seal downflow side level decreasing and delaying the

loop seal clearance. The third discrepancy of the calculation in

comparison with the experiment is that the higher vapor-phase break flow

rate (after 160 seconds) results in a fast primary mass loss and

therefore in an ancitipated earlier accumulator injection.

In the base calculation with the RELAP5/MOD3, the first and the

third disagreements described above were still observed. The liquid

holdup in the upflow side of the steam generator U-tubes was predicted

well with the experiment, however the complete loop seal clearing was not

occurred throughout the transient. This discrepancy was cleared by the

nodalization changes in the steam generator U-tubes and the cross-over

legs and the calculated results were in good agreement with the

experiment in the evolution of the major thermal-hydraulic phenomena and

their timing order.

10. SUPPLEMENTARY NOTES

11. ABSTRACT I200 wors orIeo

5% cold leg break test, run SB-CL-1 8, conducted at the Large Scale Test Facility (LSTF) was analyzed using

RELAP5/MOD2 Cycle 36.04 and RELAP5/MOD3 Version 5m5 codes.

The test was conducted with the main objective being the investigation of thermal-hydraulic mechanisms

responsible for early core uncovery, including manometric effect due to an asymmetric coolant holdup in the steam

generator upflow and downflow side.

The present analysis, carried out with RELAP5/MOD2 and MOD3 codes, demonstrates the code's capability to

predict, with sufficient accuracy, the main phenomena occurring in the depressurization transient, both from a

qualitative and quantitative point of view. Nevertheless, several differences regarding the evolution of phenomena

and affecting the timing order have to be pointed out in the base calculations.

The sensitivity study on the break flow and the nodalization study in the components of the steam generator U-tubes

and the cross-over legs were also carried out. The RELAP5/MOD3 calculation with the nodalization change

resulted in good predictions of the major thermal-hydraulic phenomena and their timing order.
