Abstract

SNUF experiment on hot leg break large break loss of coolant accident during postblowdown was analyzed by RELAP5. As same with the procedure of SNUF

experiment, normal operation and blowdown phase were simulated in order, and the

initial condition was obtained and compared with the experimental initial condition.

The analysis of post-blowdown phase showed that the behavior of primary pressure

can be properly simulated by RELAP5 when sufficient heat source is modeled.

Resultantly, the release from reactor side broken section and steam generator side

broken section were properly predicted. The pressure rise in the second step of

pressure behavior was partially well predicted, where the pressure increased by the

steam generation in core. The release from the steam generator side broken secticn was

predicted to be little except when there exits large pressure difference between primary

system and break boundary. Break size did not affect much on the overall behavior to

some degree.

Executive Summary

This document describes an assessment of beta version of RELAP5/MOD3.2.2 code with Seoul

National University Facility (SNUF) test. The SNUF is scaled down model of Young Kwang

Nuclear Power Plant Units 3&4 (YGN Units 3&4) with volume ratio 1/1140. And tlhe design

was based on the Ishii's three level scaling law. The experiment simulated a hot leg break large

break loss-of-coolant accident (LBLOCA) during post-blowdown.

To evaluate the code predictability for specific thermal hydraulic phenomena of hot leg break

LBLOCA during post-blowdown, the major thermal hydraulic phenomena observed in the

experiment were investigated. Those phenomena include the cold leg refill, steam generation in

core and resultant repressurization, and negligible coolant release through the SG side broken

section.

The SNUF was modeled as suitable for simulating the experiment, based on the available

information on the design and test procedures such as normal operation, drain-down, and postblowdown. Prior to the preparation of base case input deck, pressure drop test in SNUF was

conducted, and the experimental result was reflected in loss coefficient in input deck. The

normal operation, the drain-down, and post-blowdown were assessed in order, according to the

procedure of experiment.

The base case calculation was executed, the result was compared with the experiment data, and

the code predictability on the important thermal hydraulic phenomena was discussed. Sensitivity

calculations were attempted to evaluated the effect of modeling of heat structure (RunC'2), break

boundary pressure (Run03), and break size (RunO4, Run05). The main parameters for

comparison with experiment were system pressure, discharged amount in each broken section,

water level in U-tube, and temperature in reactor lower plenum. The analysis rc:sults are

summarized as follows;

1) System pressure was properly predicted, showing the three distinguished steps; first

step in which the pressure decreases rapidly, second step in which the pressure slightly

increases due to the steam generation in core, and the third step in which the pressure

goes stable. The predicted decrease rate of pressure in first step was similar with

experiment. In the second step, the predicted pressure increased slightly due to the two

ix
phase pressure drop in break junction, and the pressure increased a little more than

experiment. In third step, no more complicated phenomena were shown even though

the pressure showed small instability.

2) The discharged mass through the reactor side broken section showed good agreement

with experiment. In first step, pure steam release was predicted. The timing when the

main release began because of two-phase release was predicted to be similar with

experiment.

3) The discharged mass through the SG side broken section showed roughly similar trend

with experiment. In first step, small mass release was predicted because of large

pressure difference between system and break boundary. In second step, small mass

release was also revealed in calculation because the pressure in second step was

predicted to be higher than experiment.

4) The water level in U-tube in second step was predicted to be higher than the experiment

since the pressure in second step was higher than experiment.

5) The cold leg was refilled earlier than reactor vessel as experiment, which was checked

by the water level in cold leg and U-tube.

6) The temperature in reactor vessel lower plenum showed slightly higher than experiment.

However, the temperature near the lower plenum was similar with experiment.

7) Sensitivity study indicated that the modeling of heat structure is very important and that

the break size is not so decisive to some degree.

I. Introduction

In postulated LBLOCA (Large Break Loss-of-Coolant-Accident), coolant release continues over

several phases like as blowdown and post-blowdown phase (refill, reflood and post-reflood

phase). During blowdown phase, most of the initial primary coolant is released to containment.

However, during post-blowdown, the evaporation of Safety Injection (Si) water in the reactor

core can contribute to the containment pressure rise and thus generate the second peak pressure,

which will be the criteria of containment design pressure in most nuclear power plants. During

that phase, the Steam Generators (SG's) heat removal has different characteristics depending on

break locations.

For cold leg break, the steam and entrained water carried out of the core pass through the SG,

where the entrained water is evaporated or can be superheated to nearly the temperature of the

SG secondary system temperature by reverse heat transfer. Therefore, in conservative licensing

analysis, containment can be repressurized during the post-blowdown phase under the

assumption of this reverse heat transfer mechanism. However, for hot leg break, majority of

coolant from the core is expected to be directly discharged to the containment without passing

the SG, since the broken hot leg provides a direct release path [1]. Thus, in the case of hot leg

breaks, quantitative analysis for the post-blowdown phase has not been performed usuflly in the

safety analysis report. And it was a general trend that the containment peak pressure occurred

during post-blowdown phase for the cold leg break, and the peak pressure was higher than the

blowdown peak pressure of the hot leg break. Therefore, the cold leg break case was recognized

as a limiting design basis event in the determination for containment design pressure [21.

However, the maximum containment pressure accident was inconsistently reported in

preliminary safety analysis report (PSAR) and final safety analysis report (FSAR) of Young

Kwang Nuclear Power Plant Units 3&4 (YGN Units 3&4), which is the base o:- Korean

Standard Nuclear Power Plant. Double Ended Discharge Leg Slot Break (DEDLSB) was

reported to be such an accident in PSAR, while Double Ended Hot Leg Slot Break (EEHLSB)

in FSAR [3]. This is contradictory from previous trends. Therefore, it became very important to

investigate the realistic behavior of hot leg break LBLOCA during post-blowdown.

Korea Atomic Energy Research Institute (KAERI) implemented RELAP5 analysis for

LBLOCA of YGN Units 3&4 to investigate the realistic behavior of LBLOCA in YGN Units

-I-
3&4[4]. However, the predictability of RELAP5 for hot leg break accident has not been

sufficiently discussed yet. In Seoul National University, an experimental study for hot leg break

LBLOCA during the post-blowdown was carried out to support the regulatory evaluation of this

issue with the facility, Seoul National University Facility (SNUF), which simulates YGN Units

3&4 with volume ratio 1/1140 [5]. The objective of SNUF test was to investigate a

characteristic feature of hot leg break LBLOCA during post-blowdown phase. The experiment

indicated that the SI water refilled the suction part of cold leg first and refilled the core later.

Steam generation in core gave rise to the pressure of reactor coolant system and the

repressurization forced the coolant in cold leg to flow up to some height of U-tube of SG.

However, the time duration that the coolant stayed in U-tube was short, and the resultant coolant

release from SG side broken section was negligible such that the SG could be regarded as a

minor heat source of coolant release [5].

The objective of this study is to evaluate the predictability of RELAP5/MOD3 on major thermal

hydraulic behaviors during the post-blowdown of hot leg break LBLOCA of YGN Units 3&4.

Such transient hydraulic behaviors include the cold leg refill, steam generation in core and

resultant repressurization, and negligible coolant release through the SG side broken section.

The code used in this study was the standard version of RELAP5/IMOD3.2.2 beta, which was

known to have the improved features from the previous version of RELAP5/MOD3 [6].

The Chapter II includes a brief description of SNUF, the experimental condition and procedure.

The Chapter M describes the modeling of SNUF nodalization. The Chapter IV discusses in

detail the calculation results with experimental results. In particular, the discussion involves an

assessment of the major phenomena of hot leg break LBLOCA during post blowdown. The

code predictability and run statistics are also described in this chapter. The conclusions are

derived through present study and summarized in the Chapter V. Finally, input deck for steady

state run, drain-down run, and post-blowdown run are attached in Appendices A, B, and C,

respectively.

H. Facility and Test Descriptions

11.1 Facility Description

The Seoul National University Facility (SNUF) is a scaled integral experimental test facility of

the YGN Units 3&4, one of the Combustion Engineering type Pressurized Water Reactor in

Korea. The facility was constructed in the Seoul National University (SNU). Its length scale

ratio is 1/6.4, area scale ratio (1/13.4)2, and resultantly, the volume scale ratio 1/1144-. Figure 1

shows the configuration of SNUF, and Figure 2 shows its schematic diagram. The design and

the scaling were based on the Ishii's three level scaling [5,7]. The important geome:ric design

parameters are presented in Table 1.

The SNUF has appropriate components of primary system and secondary system fox mass and

energy release experiment. The facility consists of a reactor vessel, two SG's, an intact loop

with one cold leg and one hot leg, a broken loop with one hot leg and two cold legs, two

discharge tanks, and SI system.

The reactor vessel contains 60 kW electrical heaters to simulate the scaled 2.2% core decay heat

power, which is corresponding to the decay heat at 15 seconds after reactor trip plus the heat of

inner metal structures. At the lower part of reactor vessel, the drain valve is piped outwardly for

primary coolant drain during the drain-down phase.

A SG is equipped in each loop, and each SG contains four U-tubes with the height of 1725 mm,

six U-tubes with the height of 1643 mm and six U-tubes with the height of 1562 mm. Inner and

outer diameters of U tubes are 19 mm and 21 amn, respectively. The secondary system is

composed of SG shell, steam line and feedwater line.

The intact loop has a hot leg and a cold leg. The two cold legs are scaled into a lumped single

cold leg to have the similar volume. At the hot leg, a window glass is also installed to observe

the behavior of fluid.

The broken loop is composed of one broken hot leg and two cold legs. The broken hot leg is

designed to simulate double ended guillotine break, and thus comprises of two broker sections,

i.e. the reactor side broken section and the SG side broken section. The broken sections are

-3-
simulated using ball valves, and an isolation valve is installed between the two broken sections.

Since the isolation valve is instantly closed at the beginning of the experiment, the mass releases

from each broken section can be measured independently. Two window glasses are installed in

hot leg for the direct visual observation of fluid behavior. A window glass is also installed in

cold leg suction part for the sake of direct visual observation of fluid behaviors in the early stage

of ECCS injection.

Discharge tanks connected to each broken section simulate the containment. Thus, the size of

each discharge tank was determined to be sufficient for the expected discharge amount. The

capacity of the reactor vessel side discharge tank is about 150 liter with diameter of 600 mm and

height of 700 mm, while that of the SG side discharge tank is 30 liter with diameter of 300 mm

and height of 700 mm. Those two discharge tanks were interconnected with each other with 1/2

inch pipes in order to maintain the same pressure. Each discharge tank contains a cooling

system to condense the steam immediately, and then the discharge amount can be measured by a

level meter.

The SI system is composed of a storage tank, a SI pump and a flow controller. The storage tank

is equipped with electrical pre-heaters of 20 kW in order to control the temperature of SI water.

The SI line is connected to cold leg.

11.2 Measurement Instruments

The measurement instruments are listed in Table 2 with the uncertainties. Ten thermocouples,

one pressure transducer, two level meter and one flow meter were used.

The steam and water which are released through each broken section are condensed or cooled

down in each discharge tank and then the water level is measured. The discharged amount is

calculated by multiplying the level by the cross sectional area of each tank. The temperatures

were measured, as shown in Figure 2. The fluid temperatures in upper and lower parts of each

broken section are measured to investigate the stratification, and the temperature at the half

height of U tube is to catch up the flowing up of cold SI water into the half height of U tube.

The T type thermocouples were used, which is known to have excellent performance in the

range of -2001C -4001C. The absolute pressure is measured at the reactor top head with

PDCR922 and DPI 260 model made in Druck Co.. The flow rate is measured at the SI system

-4-
with DPI03 wet-wet type. The volumetric flowrate is correlated with the pressure drop across

the orifice.

11.3 Experimental Conditions and Procedures

The SNUF experiment simulated the post-blowdown transient of hot leg break LBLOCA. Thus,

the initial condition is End-Of-Blowdown (EOB). Initial condition of experiment was carefully

established. The result of RELAP5 analysis for YGN Units 3&4 was used as reference initial

condition [2,4]. The RELAP5 analysis did not show such an EOB point where the primary

pressure became same with the containment pressure. Thus, in this experiment the EOB was

assumed to be about 15 seconds elapsed from the initiation of accident. The RELAP5 analysis at

this time showed that the primary pressure was decreased close to containment pressure, and

that the core was fully voided. Resultantly, the collapsed liquid level of the reac:tor fell to

minimum [2,4].

The experiment was conducted in following procedures as shown in Figure 3; pressure drop test,

normal operation, drain-down, and post-blowdown. The result of pressure drop test was to

check the characteristics of loop, and it was reflected in the determination of loss coefficients.

The results of pressure drop test is listed in Table 3.

In normal operation, the primary system and the secondary system were maintai:ned nearly

saturated at 0.8MPa and at 0.5MPa, respectively. The core power was 60kW. Important

operation conditions are presented in Table 4. From this condition, the primary water inventory

was drained until the water remained only at the lower plenum. This procedure is the draindown phase. In the drain-down phase, the coolant in the cold leg suction part did not flash up

but remained as saturated or subcooled water. Thus, in experiments the coolant was artificially

drained. The temperature of secondary system was higher than that of primary systenm, and the

secondary system could play a role of heat source if the injected SI water passed through U

tubes. From this drain-down process, the initial condition of experiment was obtained, and it is

compared with EOB condition of YGN Units 3&4 in Table 5.

At the commencement of experiment, the SI pump operated, each discharge valve opened to

simulate the break, and the isolation valve was closed at the same time. The main power was

turned on earlier by 30-40 seconds for preheating than the start of the experiment. The SI

-5-
temperature was maintained as 60°0, which was a little higher than that of real plant in order to

compensate for the lack of the heat capacity of the RCS metal, and the SI flow rate was

maintained constant at the rate of 2.2lit/sec. The core power was set as 60kW.

In. Code and Modeling

HI.1 Code Description

The RELAP5 code has been developed as one of the best estimate-codes. The code is based on a

non-homogeneous and non-equilibrium two-fluid model and constitutive equations for one

dimensional two-phase system. In this study, unmodified released version, RELAP5,MOD3.2.2

beta version, was used, and input decks are prepared based upon the RELAP5/MlOD3 [7].

RELAP5/MOD3.2.2 beta version was installed in personal computer of Pentium-rII 500 MHz.

111.2 Modeling Description

In the analysis of SNUF experiment, the calculation procedure traced the procedure of

experiment; calculation of pressure drop, calculation of normal operation (steady state run),

calculation of drain-down (drain-down run) and finally calculation of post-blowdown (postblowdown run), as shown in Figure 3.

1. Preparation of Input Deck and Steady State Calculation

The base case nodalization for SNUF experiment is shown in Figure 4. This base nodalization is

composed of 147 volumes, 151 junctions, and 101 heat structures. All important components

like as a reactor vessel, a downcomer, two SG's, an intact loop, a broken loop, and secondary

system were modeled. Downcomer and suction leg where rapid transient is expected are nodded

finely. The downcomer was modeled with separated channel in order to reflect the asymmetric

behavior of two loops. All the heat structures of primary system are modeled including

electrical heaters. Each leg is connected to reactor vessel or downcomer with cross flow

junction.

For the exact simulation of pressure drop over the loop, the results of pressure drop test of Table

3 were reflected through the loss coefficients. The pressure drop experiment was carried out

under the condition of atmospheric pressure with 251C water. The pressure drop was .significant

at the inlet and the outlet of the reactor vessel and the SG. Loss coefficients at the other parts

were determined referring the fluid handbook [8], since the pressure drops at the other parts

were comparatively small.

-7-
Reflecting such pressure drops, a steady state was obtained from the calculation of normal

operation. The results are presented in Table 4, and compared with the experimental condition.

The primary system was 0.8MPa, and nearly saturated. The secondary system was 0.5MPa, and

saturated. The core power was 60kW.

2. Simulation of Drain-down and Initial Condition

In the beginning of SNUF experiment, all coolant in primary system was drained except in

reactor lower plenum, and the primary pressure was 0.35MPa. To obtain these conditions, draindown nodalization is used in the Figure 4. Valve junctions J991, J993, J995 and J999 are opened

and time dependent volumes C992, C994, C996 and C998 are used. The primary coolant is

drained from reactor lower plenum (through J999) and each bottom of cold leg (through J991,

J993, J995) as the SNUF experiment. The drain is stopped when the liquid levels of reactor and

each cold leg are below 65mm and 20mm, respectively. Even after the drain was complete,

dummy calculation was continued for a few ten seconds in order to obtain the stable state of the

system. In the calculation, the liquid level is defined as collapsed water level determined from

the void fraction in the volumes of reactor vessel and suction legs.

L= (I- a )'Hi(1)

,where L is collapsed water level,

a is void fraction,

H is height of volume.

As a result, initial conditions obtained from this calculation are shown in Table 5, and the

results are consistent with initial condition of experiment.

3. Simulation of Post-blowdown

For the simulation of post-blowdown, the drain-down nodalizations (J991, J993, J995, J999,

C992, C994, C996, and C998) was removed. The nodalizations for the SI line (C900, C902,

C910, C920, C930, J901, J911, J921, and J931) and the breaks were added. The SI water of

601C is provided from time dependent volume C900, and is branched to each cold leg. The SI

flowrate was set constant as 2.2kg/s, and modeled using time dependent junction, J901. The

break is modeled as double ended break, and from two broken sections the coolant is released.

-8-
The two break boundaries, C954 and C964, are modeled using time dependent volume filled

with saturated steam. The isolation valve J411 was also closed. The important conditions are

listed in Table 6, compared with experimental conditions.

IV. Results and Discussions

The considered calculation cases are listed in Table 7. RunOl is base case. In the base case, all

the heat structures in primary system are modeled including electrical heaters, and the break

boundaries filled with saturated steam are maintained as atmospheric pressure. Run02 is same

with base case except that only electrical heater and U-tubes are modeled in heat structure in

order to evaluate the effect of heat structure modeling. Run03 assumes the pressurization of

break boundary according to primary pressure transient. The condition of pressurized break

boundary is more faithful to the definition of EOB, since EOB is generally the time when the

primary pressure decreases to the containment pressure. RunO4 and Run05 are for the evaluation

of break size. In Run04, the break size is same with the cross-sectional area of hot leg, and in

Run05, it is half of the cross-sectional area of hot leg. The break size of base case is smaller

than that of RunO4, and larger that that of Run05.

IV.1 Results of Base Case (Run0l)

1. Pressure of primary system

Figure 8 shows comparison of the pressure of reactor vessel top head between the calculation

and the experiment. In the experiment, the pressure behavior can be classified into three

distinguished steps; first step in which the primary system pressure decreases rapidly, second

step in which the pressure increases slightly and last third step in which the pressure decreases

slowly toward steady state. The first step extends from 0 to 40 seconds, the second step from 40

to 80 seconds, and the thirds step from 80 seconds to the last [5].

The first step is characterized by rapid decrease of pressure due to the steam release. For this

step, the RELAP5 shows the good agreement with experiment, and the rate of pressure decrease

is also similar with experiment. However, the timing that the pressure reaches the minimum is

earlier than experiment by a few seconds.

Second step is characterized by slight increase of pressure due to the steam generation in core.

RunOl could not perfectly predict such a behavior. At about 60 seconds, the pressure in

experiment reaches the peak, and the RunOl also shows such a pressure rise. The predicted

pressure rise in RunOl is higher than that in experiment. In experiment, since much steam was

-10-
generated when the SI water reached the bottom of core, and little steam was generated after the

core was fully refilled, the mild increase and decrease of pressure behavior were observed.

Whereas, the pressure rise before core refilling was not predicted, however after tie mixture

level of core increased to the hot leg level and the two-phase mixture began to be released, the

pressure rise was induced by the loss coefficient at reactor out let. The starting point of twophase mixture release is very close to the time when the discharge amount (integrated break

flow) begins to increase drastically, which will be discussed in next section. Consequently, in

the second step, RELAP5 seems to predict at least the characteristic feature of pressure behavior.

In third step, no more transient is expected thereafter in experiment. The RunOl shows

intermittent increase and decrease of pressure, which is thought to be caused by the unstable

direct contact condensation of steam and subcooled water in reactor upper plenum. Figure 6

shows that the void fraction in upper plenum (C21001) is decreased by condensation after 90

seconds, and that the void fraction is decreased rapidly after 105 seconds when the rafid change

of pressure appears. Consequently, RELAP5 well predict the overall pressure behavior in third

step with intermittent instabilities.

2. Mass and Energy Release

Discharged masses (integrated break flow) through reactor vessel side broken section and SG

side broken section are presented in Figures 7 and 8, respectively. The figure for the discharged

mass of reactor vessel side broken section shows that there is only steam release during first step

of pressure behavior, however, it seems that the steam release in experiment was not sufficiently

measured since the release was measured by condensing the steam. The result of RELAP5

analysis revealed that a little steam is released before 10 seconds when the pressure decreases

rapidly. However, after 15 seconds, little steam is released, and no increase in discharged mass

is revealed.

In experiment, from about 60 seconds, two-phase mixture was initiated to be released. RELAP5

analysis of Figure 7 shows that the release rate is increased slightly before 60 seconds, and that

main release is initiated slightly after 60 seconds. The initiation of two-phase release causes the

larger pressure drop in reactor vessel outlet, and the pressure of reactor vessel is increzsed.

After 60 seconds, the experiment shows the stable release, however the RELAP5 sihows the

-11-
unstable one. It seems caused by the unstable direct contact condensation in reactor vessel upper

plenum, as shown in Figure 9. As the Figure 9 shows, it can be seen that the void fraction in

C20001 was more unstable than the void fractions in the other volumes.

In Figure 8, the experiment shows nearly zero discharge through the SG side broken section,

however the RELAP5 shows some discharge in 15 seconds and 65 seconds. This phenomenon

is related with the water level in U-tube, which will be discussed in the next section on water

level.

3. Water Level

As discussed in experimental result, the SI water refills the cold leg first. The SI water flows up

to the U-tubes by the repressurization of reactor vessel in the second step of pressure behavior

as shown in Figure 10. Figure 11 shows the collapsed water level in U-tubes from the RELAP5

calculation. High water level was predicted at about 10 and 60 seconds. In experiment, the water

level was detected by measuring the fluid temperature at middle height of U-tubes as shown in

Figure 12. The water level reaches the location of thermocouple from the fact that the fluid

temperature drops rapidly twice by cold water. The first level rise at 10 seconds in Figure 11

was caused by the large pressure difference between the reactor vessel and break boundary. As

the water level increases up to such a height, some of the water is released through the SG side

broken section. Resultantly, there was a little coolant release through the SG side broken section,

as shown in Figure 8. Consequently, the RELAP5 well predicted the fact that water lever in Utube rose twice at about 10 and 60 seconds, but the predicted water levels were higher than

experimental ones. Such a behavior in early transient is largely affected by the boundary

pressure, and it will be discussed once more in the analysis of Run03.

In the third step of pressure behavior, the experiment revealed that there was no more water

level rise up to the middle height of U-tube. And, the REPAL5 analysis also showed the same

result with experiment.

The Figure 13 shows the water level of suction leg in broken loop. In the experiment, the level

was identified by the direct observation or taking pictures through the transparent window glass.

The experiment revealed that the suction leg was refilled most early and there was slight

oscillation only while the leg was being refilled. And, after the suction leg got refilled, the fluid

-12-
in the suction leg was stabilized. But, the RELAP5 analysis shows the continuous os.cillation in

water level as shown in Figure 13. This is caused by the unstable condensation in s;uction leg,

which can be seen in Figure 14.

4. Temperatures

The temperature measured in experiment is local time averaged temperature:, and the

temperature of RELAP5 is volume averaged and time averaged temperature. In Figure 15, the

temperatures of RELAP5 are the liquid temperatures (tempO. The Figure 15 compares the

experimental temperature and RELAP5 temperatures near the measured point. The t,.-mperature

of C13205 is similar with the experimental result, however the temperatures of C16001 and

C 14205 are higher than experiment's.

The fact that the temperature of C14205 is higher than that of experiment is caused by the

distribution of SI water in downcomer as shown in Figure 16. The total SI flow rate was

constant as 2.2kg/s. However, the larger SI pipe size of the intact loop than that of broken loop

leads to the more injection to the intact loop than broken loop as shown in Figure 17, which

induces the more condensation of steam, and the lower pressure in intact side dwncomer.

Therefore, because of such a pressure gradient between the intact side and broken side in

downcomer, the SI water in intact side flow to the broken side along the downcomer wall.

Resultantly, most of the SI water is injected through the intact side downcomer as shown in

Figure 16, and the temperature of C14205 is predicted higher than that of C 13205.

The volume of lower plenum, C16001, contains a little saturated water at the beginning, and as

the transient goes on, the water swells to flow up to the core, which heated the water more. Such

a swelling can be seen from the behavior of void fraction in Figure 18. The void fraction in

C16001 is small at first, and undergoes the increase and decrease in order. Thus, the: predicted

temperature is revealed higher than the experiment.

Such a temperature difference can be explained related with thermal mixing in rea:tor lower

plenum. According to the study about thermal mixing in reactor lower plenum with SNUF, even

in higher mass flow rate the thermal mixing was not prominent [9].

IV.2 Sensitivity Studies

1. Run02 - Effect of Heat Structure

The Figure 19 compares the pressure of reactor top head in Run02 with that in experiment and

base case. The pressure in Run02 shows more rapid decrease of pressure than that in experiment

and base case in first step. The pressure rise in second step was not well predicted. This fact

means that the heat of metal structure is important in the analysis of mass and energy release, as

mentioned in FSAR of YGN Units 3&4. Therefore, the modeling of heat structure in the

analysis of mass and energy release is very important

Discharge amounts (integrated break flow) through reactor side broken section and SG side

broken section in Run02 are presented in Figures 20 and 21, respectively. The Figure 20 shows

that the discharge amount in Run02 is similar with that of Run0l, however, the Figure 21 shows

that Run02 does not predict the second release through SG side broken section because there is

no pressure rise in second step. Resultantly, as Figure 22 shows, the water level in U tube in

second step does not increase.

2. Run03 - Effect of Boundary Pressure

In Run03, the break boundary is pressurized like as Figure 23, where the boundary pressure is

slightly lower than the reactor vessel pressure in first step of experiment. The predicted pressure

of reactor top head is shown in Figure 24 comparing with experiment and base case. The

pressurization of break boundary led smaller rate of pressure decrease. The release through the

reactor side broken section in Figure 25 shows earlier two-phase release than Run0l. It is

because in the earlier transient, the release through the SG side broken section in Figure 26 is

very small compared with Run0l, because of the smaller pressure difference between system

and boundary. The water level in U tube in first step is also lower than that of RunOl as shown

in Figure 27. Consequently, the result of Run03 implies that the effect of boundary pressure

does not affect much on the overall behaviors.

3. RunO4 and Run05 - Effect of Break Size

-14-
RunO4 and Run05 are to evaluate the effect of break size. The break area in RunO4 is same with

the cross-sectional area of hot leg, and that in Run05 is half of the cross-sectional area of hot leg.

The pressure in reactor vessel top head shows similar trend with base case in spite of the

difference of break area as shown in Figure 28. Discharge amount from each broken section and

water level in U-tube are also similar with base case as shown in Figures 29, 30 and 31. From

this fact, it can be concluded that the break size in post-blowdown is not so important to some

degree.

IV.3 Run Statistics

IBM compatible personal computer of Pentium-III 500 MHz was used in calculation with

Microsoft Windows NT 4.0 version. The personal computer has 256 MB main memory.

Calculation in drain-down was attempted to 1200 seconds and, calculation in post-blowdown

was attempted from 1200 seconds to 1320 seconds. The base case run was stccessfully

terminated at 1320 seconds. The calculation time is shown in Figure 32, setting 1200 :;econds as

0 second, and 1320 seconds as 120 seconds. For 5 seconds from 1200 seconds to 1205 seconds,

fine time step was used, and the required calculation time was more than in the other calculation.

The base case run was terminated at 1320 seconds, and the required CPU time in personal

computer was 1767.33 seconds including 0.468750 second for input processing. The attempted

advancement was 67572 time steps. Therefore, the grind time for the base case can be

calculated as follows;

CPU Time, CP = 1767.33 - 0.468750 = 1767.33 seconds

Number of Time Step, DT = 94766-27194= 67572

Number of Volume, C = 134

Transient Real Time, RT =120 seconds

Grind Time, GT = (CP*1000)/(C*DT)

= (1767.33*1000)/(134*67572)

= 0.1952 m CPU sec/(vol-step)

V. Summary and Conclusion

The RELAP5/MOD3 was assessed using SNUF experiment simulating hot leg break LBLOCA

in the view of mass and energy release analysis. In order to evaluate the code predictability on

major thermal hydraulic behavior, the calculation results were assessed and compared with the

experimental data.

SNUF is scaled down model with volume scale ratio 1/1144 simulating YGN Units 3&4. The

SNUF experiment showed that most of injected SI water was released through the core side

broken section and thus the release through the SG side broken section was negligible. The

remarkable feature is that the SI water refilled the cold leg first, and resultantly the steam

generated in core could not be heated directly by SG. Although this experiment showed that the

water in cold leg could flow up to a half height of U tubes, the duration time was not sufficiently

long for the SG to be taken as a major heat source.

RELAP5 analysis for the SNUF experiment showed that this code can properly predict the

important features of hot leg break LBLOCA during post-blowdown, when all the heat

structures are modeled. And the releases from reactor side broken section and SG side broken

section were also predicted satisfyingly. Especially, the pressure rise in second step of pressure

behaviors were predicted partially, and the release from SG side broken section was little except

when the pressure difference between the primary system and break boundary is not large in

early stage of transient. However, since the unstable direct contact condensation in suction legs

resulted in the unstable behavior of water level, they were different from experimental results.

Break size did not affect much on the overall behavior to some degree.

10. SUPPLEMENTARY NOTES

11. ABSTRACT (200 words or less)

SNUF experiment on hot leg break large break loss of coolant accident during post-blowdown was analyzed by RELAP5. As

same with the procedure of SNUF experiment, normal operation and blowdown phase were simulated in orier, and the initial

condition was obtained and compared with the experimental initial condition. The analysis of post-blowdown phase showed that

t he behavior of primary pressure can be property simulated by RELAP5 when sufficient heat source is modeled. Resultantly,

the release from reactor side broken section and steam generator side broken section were properly predicted. The pressure.

rise in the second step of pressure behavior was partially well predicted, where the pressure increased by the steam generation

in core. The release from the steam generator side broken section was predicted to be little except when there exists large

pressure difference between primary system and break boundary. Break size did not affect much on the overall behavior to

some degree.
