RELAP5 Assessment Against PACTEL Experimental Data

Abstract

The results of the pre-test and post-test calculations of OECD International Standard Problem

no.33 (ISP-33) are presented. The frozen version of RELAP5 code version MOD2 and the latest

released version MOD3.2 have been assessed against experimental data from PACTEL facility.

Generally, predictions were in good agreement with experimental data, except in the most

interesting part of the transient only MOD3.2 was able to follow periodic hot leg loop seal

clearance phenomena and primary pressure oscillations closely.

INTRODUCTION

In the 1990's the interest for eastern nuclear power plants safety has increased significantly.

The VVER-440 heat removal capability in accidental situations has been studied mostly. VVER-440

nuclear power plants (NPPs) differ considerably from western type Pressurized Water Reactor

(PWR) plants. The main distinguishing characteristics, beside horizontal steam generators, are loop

seals not only in cold but also in hot legs. The horizontal steam generator (SG) design degrades

natural circulation driving force. The top of SG tubes is only at about 1 m higher elevation than

hot leg connection to the reactor vessel. Along with the hot leg loop seal such construction almost

disables the reflux cooling process in the case of Small Break Loss-of-Coolant Accidents (SB

LOCA).

Nuclear safety oriented OECD ISP-33, focused on VVER-440 core cooling capability,

started in 1992. The experiment, performed on the PACTEL integral test facility, built in

Lappeenranta, Finland, simulated different stages of a Small Break Loss-of-Coolant Accident (SB

LOCA). Natural circulation is essential for decay heat removal in the accident situations of the light

water reactors. The experiment with stepwise reduction of primary inventory was considered

relevant for VVER-440 safety since it would demonstrate the ability of the plant to remove decay

heat with different amounts of primary inventory, developing different patterns of natural

circulation. Since VVER-440 and PACTEL facility are equipped with horizontal steam generators,

which lowers the elevation between core and steam generator tubes, the study of natural circulation

was strongly desired for this kind of nuclear power plant.

PACTEL FACILITY DESCRIPTION

The PACTEL integral test facility [1, 2] in Finland (Figure 1) is a 1:305 scaled down 3-

loop model of a 6-loop VVER-440 PWR NPP, ex-Soviet design, also built in Finland.

The facility consists of reactor vessel model, external downcomer, three loops with three

SGs and a pressurizer connected to hot leg no. 1. Reactor core is modelled by 144 electrically

heated rods, in three separated parallel triangularly shaped BWR-like channels. All the elevations

in the facility are preserved as on the original plant. The same is valid for active core height, since

heater rod length is 2.5 m. Axial power distribution is uniform. Maximum core power is only 1

MW which is about 20% of the scaled nominal power (1475 MW / 305 = 4.84 MW). There were

no primary coolant pumps built in the facility, thus only natural circulation driven experiments were

possible to be conducted on the facility at the time of the test. The Emergency Core Cooling

Systems (ECCS) are also installed on the facility, but neither, high pressure, low pressure system

nor passive hydroaccumulators were in action during the ISP-33 experiment. Each steam generator

contains 38 horizontal heat exchange U-tubes with the average length of 8.8 m. The secondary

water level control is performed by means of manual feedwater control.

There is an instrumentation system, consisting of a data acquisition unit, a controller and

a workstation, dedicated to the PACTEL facility.

PACTEL COMPUTER MODEL DEVELOPMENT

The ISP-33 experiment was announced as a blind exercise. However, since it was supposed

that there was not enough experience in modelling VVER-440 plants or their scaled-down models

at that time, the data for a special, so called "characterizing test" were distributed among the

participants in the pretest period. The characterizing test included some elements of the later ISP33, so that the participants could tune the response of their models to a part of the SB LOCA

sequence. The "characterizing test" has been performed on PACTEL facility prior to ISP-33

experiment.

A full 3-loop model has been developed at US [3] and is shown in Figure 2. It consists of

221 hydrodynamic volumes, 238 junctions and 259 heat structures with 1263 mesh points. Three

parallel core channels were modelled lumped together as one channel. First MOD2 model [4] has

been developed and initialized into another steady state condition, corresponding to the

"characterizing test" data. The MOD3.2 deck was simply copied from the previously developed

MOD3.0 deck, originating from MOD2 and upgraded only as much as requested in the Manual [5].

Finally, both models have been driven to 155 kW core power and initialized to the actual

ISP-33 steady state conditions.

Characterizing Test Description

The characterizing test started from steady-state natural circulation at 180 kW core power.

For demonstrating the system response with two pressurizer heater power levels and system

behaviour with a small letdown is demonstrated with the following events:

(A) The pressurizer heaters power has been controlled manually. It was set to 4 kW at the

beginning of the test, switched to 2 kW after 1260 seconds and increased back to 4 kW at

2290 seconds.

(B) After 2640 seconds 13.5 kg of water has been drained from the lower plenum.

In this way some of the details in the model could be tuned, especially pressurizer response

to perturbations, which showed later to be of essential importance for the correct ISP-33 test

simulation.

Results of the characterizing test simulation

The RELAP5 simulation started from the conditions at 1260 seconds of the transient, when

the heater power was decreased to 2 kW, and followed the later sequence of events. The

pressurizer pressure response (Figure 3) is shown to be adequate in both calculations. The slope

of both curves from RELAP5 calculations is the same as in the experiment, which indicates that

the primary system inventory distribution and thermodynamic state has been modelled adequately,

as well as heat losses from different parts of the primary system. Another proof for correct

modelling of the primary inventory is the pressurizer level development after the draining at 2640

seconds (Figure 4).

EXPERIMENT DESCRIPTION

A special SB LOCA scenario with stepwise reduction of the primary inventory has been

applied for simulation on the PACTEL facility. Initial conditions, listed in Table 1, have been

matched closely in MOD2 and MOD3.2 model initialization and stabilization processes.

After the initial 1200 s steady state, l' draining from the primary system has been

performed. At that time 60 kg (about 9 %) of the primary liquid has been drained from the lower

plenum in 180 s. During that period only the pressurizer was emptied, while reactor vessel upper

head and SG tubes remained filled with subcooled liquid. In the next 720 s period, the system was

allowed to reach the new steady state condition.

During each next draining another 60 kg of the primary inventory have been drained in

period of 60 s, following by 840 s undisturbed time intervals for the system parameters to reach

new quasi steady state.

PRIMARY SYSTEM SECONDARY SYSTEM

Core power 165 kW SG pressure 4.18 MPa

Pressurizer pressure 7.39 MPa SG levels: SG 1 0.271 m

Pressurizer level 5.18 m SG 2 0.272 m

Pressurizer heater power 2 kW SG 3 0.263 m

Downcomer flow 1.47 kg/s SG feedwater temperature 305 K

Loop flow 0.49 kg/s

Table 1: Initial Conditions for the ISP-33 Experiment

The most interesting phenomena took place between 21 and 3y draining, when single phase

natural circulation was interrupted due to primary coolant depletion and steam bubble entrainment

into hot legs. Oscillations of the pressurizer liquid level have been observed because of the

increasing primary pressure, causing several hot leg no. 1 loop seal clearings and periodic liquid

push-ups into the pressurizer.

Many other interesting phenomena were observed in the later time intervals between

draining. As the primary system was emptying, single phase natural circulation switched to twophase after the period of periodic flow blockage of single phase natural circulation. First hot legs

emptied after hot leg loop seal clearance, and later the same process was observed in cold legs.

Towards the end of the transient, the primary system emptied to such extent, that two-phase natural

circulation was interrupted and almost all the remaining primary liquid was collected in lower part

of the reactor vessel. At that time reactor core was hardly covered enough that stalled circulation

could remove the heat from the core. After the last draining core uncovered and upper part of the

rods overheated. When the peak clad temperature reached 623 K (3500C) core power was switched

off in the experiment and the test was ended, but the calculations were supposed to continue till the

peak clad temperature of 1173 K (800"C) would be reached.

A variation case experiment was performed on the facility, when, after core heatup, operator

fully opened secondary relief valves to condense the vapor in the primary system and collapse it

into the reactor vessel. This caused rapid core quenching. Only after a while, when the heater rods

overheated again, core power was switched off and the variation case was ended. The variation case

data and the corresponding RELAP5 calculated results are not presented here.

IMPORTANT PHYSICAL PHENOMENA AS PREDICTED BY RELAP5

0) before the first draining (0 - 1200 s)

The obtained steady state in the first 100 seconds of the transient was stable in MOD2

calculation. Primary pressure was controlled by pressurizer heaters cycling, keeping it within the

limits of 7.36 and 7.5 MPa. Secondary levels were controlled by automatic feedwater control and

deviated insignificantly from the desired level setpoint of 0.27 m in each steam generator.

Secondary pressure was controlled by appropriate opening of the valve, located on the steam line,

after the joining point of three steam generator lines. All the other observed parameters behaved

in a stable manner.

1) between ? and 21 draining (1200 - 2100 s)

The pressurizer was drained first. At the end of the first draining in MOD2 calculation the

pressurizer was almost completely drained. The pressurizer surge line still remained filled with

subcooled liquid. In both calculations the pressurizer level stayed slightly below 0.5 m till the next

draining.

On the other hand the very top of the upper plenum emptied and a small vapor bubble was

detected. P'imary pressure dropped close to the saturating pressure, slightly below 6 MPa.

Nevertheless, single-phase natural circulation proceeded with minor disturbances throughout this

time interval in both calculations. MOD2 calculated mass flow interruption in cold leg no. 1 very

early after the first draining.

2) between 21 and 31 draining (2100 - 300 s)

The reactor vessel upper plenum drained completely, while a larger amount of water was

pushed back into the pressurizer, more drastically in MOD3.2 calculation. In both calculations half

or more of the initial pressurizer inventory was restored. This remained till the third draining. A

pressure rise was obtained in the primary system. A large pressure spike was calculated by

MOD3.2, back up to the initial pressure level.

"Jo .ef Stefan" Institute, Ljubljana, Slovenia 0

Hot leg loop seal emptying started in all the three loops. First hot leg loop seal levels

decreased on the reactor vessel side, while vertical parts on the steam generator side remained

almost filled up with some disturbances. MOD3.2 calculated larger hot leg loop seal emptying in

all three loops on the reactor side of hot leg loop seals. Vessel inventory dropped quickly and first

voiding occurred in the core region.

Heat transfer to the secondary system was interrupted during this time interval in steam

generators 1 and 3 in MOD2 calculation, while MOD3.2 calculated interruption in steam generators

2 and 3. The flow through cold leg no. 2 was interrupted in both calculations. Two-phase natural

circulation took place through loop 2 in MOD2 and through loop 1 in MOD3.2 calculation.

3) between 31d and 4= draining (3000 - 3900 s)

Pressurizer was again drained completely. Primary pressure dropped below 5 MPa. More

voiding took place in the core. The whole part of the reactor vessel above the core was emptied

and hot leg loop seals were further emptying. The loop 2 hot leg loop seal emptied deeply on the

reactor side in MOD2 calculation. Some voiding was briefly detected in cold leg 1 in MOD3.2

calculation. Exactly the reverse happened on the steam generator side of the hot leg loop seals in

loop 1 and 2.

Some water was pushed through the steam generator 1 tubes from hot to cold side in

MOD3.2 calculation, while MOD2 calculated the liquid transfer through the SG no. 2. Two-phase

natural circulation proceeded through the same loops as in previous time interval. Vessel inventory

remained almost constant in this time interval and primary level stayed well above the active part

of the core.

4) between 4' and 5' draining (3900 - 4800 s)

Primary pressure dropped close to the secondary pressure. A slight level rise was detected

in the pressurizer, more obvious in MOD2 calculation. Heat transfer was interrupted in SG no. 2

in both calculations and restored or proceeded through the rest two steam generators. A larger

amount of liquid was pushed through the SG no. 2 and 3 tubes. Hot leg loop seals no. 2 and 3 were

cleared shortly after the 4"' draining. Larger voiding was detected in loop 1 and 3 cold legs, but

later the inventory was restored.

Steam generator tubes emptying started in loops 1 and 3. Vessel inventory slowly decreased,

but the primary level still remained above the core. Two-phase natural circulation proceeded and

was switched through loops 1 and 3 in both calculation.

5) between 5* and 6" draining (4800 - 5700 s)

Water continued to be pushed back into the pressurizer, but no primary pressure rise was

calculated. Two-phase natural circulation was severely disturbed in all the three loops. Steam

generator tubes were more than half emptied and cold legs emptying started, but the core still

8
00

University of Ljubljana 00

"Jo .ef Stefan" Institute, Ljubljana, Slovenia

remained sufficiently covered, where MOD2 calculated larger level drop. All the three hot legs

were already completely emptied by this time. Heat was transferred equally through all steam

generators.

6) between 61' and 7" draining (5700 - 600 s)

Steam generator tubes were drastically emptied. The level dropped in all cold legs. Twophase natural circulation was definitely interrupted in the whole system. Stalled recirculation within

reactor vessel became the mechanism of core heat removal. Still more water was pushed into the

pressurizer, where close to the half inventory was again restored. Larger core uncovering was

calculated especially by MOD2. First slight voiding in the reactor vessel downcomer was calculated

by MOD3.2. Heat transfer proceeded through all the three steam generators.

7) between 7"1 and 8' draining (6600 - 7500 s)

After this draining only cold leg loop seals remained filled with smaller amount of liquid

and reactor vessel downcomer started voiding. The top half of the core was already filled with

voids, but the heat removal remained sufficient to prevent core heatup. Larger amount of water was

still kept in the pressurizer vessel. Sufficient heat transfer still proceeded through all three steam

generators.

8) between the 8' draining (7500 s - core overheat to 350'C

Core level dropped quickly and a sudden core overheat started already at the beginning of

the last draining process. Level dropped in reactor vessel downcomer, mainly drained through the

break and some pushed below the core. Pressurizer draining started, but that was not sufficient to

cover the core sufficiently.

Heat transfer was suddenly interrupted through all three steam generators. The whole

primary system, except bottom part of the reactor vessel, was empty by that time. The experiment

has been prolonged after the initial core heatup, when operator applied ultimate procedure and

opened SG secondary PORV. The vapor condensed in the whole primary system and collapsed into

the core. Pressurizer was instantaneously drained. Heat transfer through the steam generators was

restored and core heatup was stopped. However, the calculations were stopped when maximum

cladding temperature reached 350*C (623 K).

RESULTS

There have been no changes introduced in any of the code versions. No deviations from the

user guidelines have been introduced in the input decks. No sensitivity cases are presented in the

report. The ISP-33 transient has been modelled up to the time when core heatup occurred in the

defined base case and no simulation of the prolonged base case or the variation case is shown here.

Basically, the model has been unchanged also for post-test calculations. Only a few changes

have been made in the facility model in the post-test period, mainly because of some deficient or

unclear initial condition data provided by the ISP-33 organizers. For the pretest calculation the core

power was set 155 kW, but in the post-test period some uncertainty in core power measurement

has been reported, so 165 kW was used for post-test calculation. The uncertainty of the

measurement data were given by the organizers as follows:

- temperatures ± 1 K

- differential pressures 0.5-1 1

- absolute pressures 0.15 -0.3 %

- flows 1-1.5%

- levels 1.5 -2.5 %

- core power 1%

Beside the mentioned change in the input model, a small recirculation flow path has been

modelled from upper plenum to upper head. This change has been introduced to achieve and

stabilize initial upper head liquid temperature and match it to the experimental data. A servo valve

has been modelled in the recirculation flow path governed by the difference of the actual and

desired upper head temperature. In the transient the servo valve opening was fixed to the value

which was stabilized in the steady-state. This procedure ensures achievement of the prescribed

upper head liquid temperature, which is one of the essential parameters influencing the order of

primary system emptying and bubble formation in the initial test period up to the second draining.

The procedure for the calculation was the same for MOD2 or MOD3.2. First the base input

deck, given in Appendix A was run in steady-state mode. When the model has stabilized

satisfactorily, the data from the output have been transferred to the base case input deck. Run mode

has been switched to transient and recalculated for one time step, only to produce restart no.0. For

the experiment simulation, run input deck, given in Appendix B, has been run from restart no.0.

Few components for artificial pressure and level control have been deleted or controllers fixed to

the final values achieved in the steady-state run. Trip logic for the experiment simulation has been

added, as well as the drain valve and a part of the steam line. The transient has been then run till

the stop trip has become true when the maximum cladding temperature has reached the prescribed

value of 623 K.

For the completeness of the shown results the complete set of comparison plots, as requested

by the ISP-33 organizers is given in Appendix C, together with the corresponding strip input deck.

First the results of the RELAP5/MOD3.2 calculations are shown. Pre-test and post-test

results are compared to the experimental data. After the lV draining, primary pressure (Figure 5)

dropped to the saturation value. Only the pressurizer has almost emptied (Figure 6), while the rest

of the primary system remained filled with liquid. Single-phase natural circulation proceeded. When

after the 2wd draining bubble was formed in all hot legs, single-phase natural circulation was

interrupted. While the heat generated in the core could not be transported to the steam generators,

primary pressure rise was observed. This pushed liquid back to the pressurizer and cleared the hot

leg no. 1 loop seal (the one with the pressurizer). Several hot leg no. 1 loop seal clearings have

been observed during this period [6]. Each time when the pressure peak was reached, liquid was

partly drained back from the pressurizer and flooded the hot leg no. 1 loop seal. After the next

draining liquid was finally drained from the pressurizer and hot leg loop seals, so the two-phase

natural circulation took over the heat removal from the core. When the primary system was further

emptied, liquid remained only in the reactor vessel, boiling as in a pool. Steam was carried to the

steam generators, condensed there an drained back to the reactor vessel. Stalled natural circulation

in the reactor vessel was shown to be sufficient to remove the heat from the core, while the core

was still covered. After the 7 ' draining the core uncovered and heated up quickly. It can be

observed that MOD3.2 calculated core heat-up one time interval too late, which means, that it was

not able to predict liquid hold-up in the primary piping.

The most interesting part of the transient, between the 2"" and 3w" draining has been

simulated very well by MOD3.2, already in the pretest calculation. The increased core power in

the post-test calculation brought some slight improvement of the calculated parameters, but the

influence of the introduced upper head recirculation can be more clearly seen. Since the upper head

temperature decrease was slower, flashing occurred earlier in the upper head. This prevented total

emptying of the pressurizer, which is an adverse influence, but it improved the primary pressure

behaviour.

More problems were encountered in the MOD2 simulation, although it has to be mentioned,

that it predicted the initial 1200 seconds of the steady state better than MOD3.2. The pressurizer

heaters were supposed to maintain the primary pressure between 7.36 and 7.5 MPa automatically

by switching between 2 and 6 kW power. It can be observed in Figure 7, that the primary pressure

response to the pressurizer heaters cycling was correct. Some early flashing occurred in the upper

head already after the 1V draining, which prevented total emptying of the pressurizer (Figure 8).

The rising primary pressure pushed some liquid back to the pressurizer, but couldn't clear any of

the hot leg loop seals, not even in the post-test calculation [6].

No significant differences were observed between pre-test and post-test calculations for both

code versions. Some more differences between MOD2 and MOD3.2 can be seen on the following

figures.

Some early flashing in the reactor vessel upper head and consequently reactor vessel

inventory depletion can be observed on Figure 9 already between 1 and 2 1d draining in MOD2

calculation. This prevent pressurizer to empty completely and less bubble was formed in hot legs.

Single phase natural circulation has only been interrupted for a shorter time. Consequently the

primary pressure rise was not sufficient to clear any of the hot leg loop seals and push as much

liquid back into the pressurizer as it happened in the experiment. The bubble has not been formed

in the upper head before the second draining in MOD3.2 calculation, so the phenomena of single

phase natural circulation interruption have been described correctly. After 61 draining it can be

observed, that reactor vessel liquid inventory predicted by MOD3.2 was slightly lower than in

MOD2 calculation, but it did not affect the further results. The calculation ended already after 7'

draining, as in the experiment.

Both calculations sbow that core level has been kept too high in both calculations after the

6' draining. This is the indication that the liquid, which has accumulated in SG tubes in the

experiment, has been drained back into the reactor vessel in RELAP5 calculations, which prevented

core heat-up already after the 71 draining (Figure 10).

COMPIUTER DATA AND RUN-TIME STATISTICS

MOD3.2 calculations have been performed on DEC Alpha with OpenVMS AXP Version

V1.5 operating system, while the calculation with RELAP5/MOD2 has been performed on SUN

Sparc 20 computer under SOLARIS 2.5 operating system. On average SUN computer is almost 4

times slower for RELAP5 calculations than DEC Alpha. RELAP5/MOD2 has not been installed

on DEC Alpha computer, since there have been certain difficulties with the Fortran optimization

option, so benchmarking was not successful.

Run-times for the pre-test and post-test calculations have been almost identical for both

machines, since input models have been only slightly changed. Thus only run-time statistics for

post-test calculations have been listed in Table 2. Time step has been kept constant at maximum

value of 0.1 seconds for all the calculations and number of repeated time steps was less than 10.

CONCLUSIONS

The ISP-33 experiment gives a very good basis for RELAP5 code assessment. The way it

was performed, provides several sets of independent data, since each time interval between draining

describes different SB LOCA phase.

Both RELAP5 code versions followed most of the transient reasonably well, with the

exception that all predicted core over-heat one time interval too late. This was due to inability of

both codes to hold as much water inside SG tubes, as the experiment showed. A post-test

calculation with MOD2 proved, that only slight incitation of SG tubes enables RELAP5 to predict

liquid hold-up in SG tubes and improves the results significantly. For MOD3.2 this was not

sufficient, so water stayed more in the reactor vessel and core heatup occurred one draining later.

Some differences between the two code version results were observed in the most interesting

part of the transient, after the second draining. While MOD3.2 predicted hot leg loop seal clearance

and liquid push-up into the pressurizer, caused by primary pressure oscillations very well, MOD2

could not clear any of them at all. These differences can partly course in different heat transfer

packages coded in the two versions. Better phase separation prediction, different interface heat

transfer coefficients calculated, more vapor generation and sharper primary pressure rise in

MOD3.2 calculations may origin in different heat transfer correlations and more sophisticated flow

regime maps in MOD3.2 than in MOD2.

11. ABSTRACT (2r" words o less)

The results of the pre-test and post-test calculations of OECD International Standard Problem no.33 (ISP-33) are presented. The

frozen version of RELAP5 code version MOD2 and the latest released version MOD3.2 have been assessed against experimental

data from PACTEL faclity. Generally, predictions were in good agreement with experimental data, except in the most interesting

part of the transient only MOD3.2 was able to follow periodic hot leg loop seat clearance phenomena and primary pressure

oscillations closely.
