ABSTRACT

The present document deals with the Relap5/Mod3.2 analysis of the small break LOCA

experiment BL-44 performed in LOBI/MOD2 facility.

LOBI(MOD2 was a PWR simulator (Integral Test Facility) installed at JRC (Joint Research

Center) in Ispra Establishment (I). Volume scaling and core power scaling factors are 1/712, with

respect to the KWU Siemens 1300 MWe (3900 MWt) standard reactor.

The expeiment is originated by a small break in the cold leg (2" equivalent break area in the

plant) without the actuation of the high pressure injection system. Low pressure injection system

actuation occurs after core dry-out and accumulators intervention is foreseen when primary pressure

falls below 4 MPa.

The Relap5 code has been extensively used at University of Pisa; the nodalization of LOBI

facility has been qualified through the application of the version Relap5/Mod2 to the same

experiment and another test performed in the same facility.

Sensitivity analyses have been addressed to the influence of several parameters (like discharge

break coefficient, time of accumulators start etc.) upon the predicted transient evolution.

Qualitative and quantitative code calculation accuracy evaluation has been performed.

1. INTRODUCTION

The performance assessment and validation of large thermaihydraulic codes and the accuracy

evaluation when calculating the safety margins of Light Water Reactors are among the objectives of

international research programs, such those organized by the committee on the Safety of Nuclear

Installations (CSNI) and the Code Application and Maintenance Program (CAMP).

Solution of these problems would ensure the effectiveness of engineered safety features and,

eventually, lead to cost reductions through better design. This activities could also contribute to the

determination of a uniform basis on which to assess the consequences of reactor system failures in

Nuclear Power Plants, refs. [1] and [2].

The execution of the experiments in Integral Test Facilities simulating the behavior of a nuclear

plant, plays an important role in this connection, both considering the system code assessment and

the possibilities to identify and characterize the relevant phenomena during off-normal conditions.

A special kind of experiments are the so called counterpart tests. These are similar experiments

performed in differently scaled facilities. It is well clear that transient scenarios measured in the

experimental rigs can not be directly extrapolated to the plant conditions. Nevertheless one of the

objectives of a counterpart test is to evaluate the influence of the geometric dimension of the loop

upon the evolution of a given accident.

Counterpart tests have been performed in four PWR simulators: LOBI, SPES, BETHSY and

LSTF, ref [3], respectively available at the European Community Joint Research Center of Ispra (I),

at SIET in Piacenza (I), at CENG in Grenoble (F) and at JAERI in Tokai-Mura (J). The selected

experiment is a small break LOCA originated by a rupture in the cold leg, without actuation of high

pressure injection system and with accumulators availability, in particular, starting from low power

conditions (about 10% of the nominal period). Both tests have been performed in the smallest

facilities, SPES and LOBI, starting from full power conditions, all other conditions being the same.

The activity documented in this report is a part of a multipurpose research aiming at the overall

evaluation and exploitation of the counterpart test database. On one hand the Relap5 system code

(Mod2 and, presently, Mod3.2) has been applied to the post test analysis of the four experiments and

to the evaluation of plant scenario during the same transient; on the other hand the experimental data

base have been evaluated to demonstrate the similarity in the behavior of the facilities, ref. [3]. The

two parts of the research have been merged and conclusions have been drawn in relation to the

scaling of phenomena and of the accuracy of thermalhydraulic code calculations.

Previous reports dealt with the evaluation of the experimental data base constituted by the four

counterpart experiments (ref. [4]) and with the qualification of Relap5/Mod2 nodalization used for

the post test analyses, ref [5], as well as with a complete evaluation of the data base leading to the

evaluation of uncertainties (e.g. ref [6]).

The present document deals with the post test analysis performed by Relap5/Mod3.2 of the high

power small break LOCA counterpart test carried out in LOBIIMOD2 facility (BL-44), ref [7].

The main objective of the high power test was to evaluate the influence of initial conditions

(particularly, high power, high mass flow rate and low steam generators pressure) upon the evolution

of the mentioned Small Break LOCA Transient.

The purpose of this report is to evaluate the performance of the Relap5/Mod3.2 in comparison

with the previous application with the version Mod2. In order to achieve this, a systematic

qualitative and quantitative accuracy evaluation has been performed. The quantitative analysis has

been performed adopting a method (ref [8],) developed at DCMN, which has capabilities in

quantifying the errors in code predictions related to the measured experimental signal; the Fast

Fourier Transform (FFT) is used aiming to have an integral representation of the code calculation

discrepancies (i.e. error between measured and calculated time trends) in the frequency domain.

2. DESCRIPTION OF TME EXPERIMENT

2.1 LOBI facility

The LOBI-MOD2 facility is a high pressure integral system test facility simulating the geometrical

and operating configuration of a four-loops 1300 MWe PWR. More in particular, it reproduces the

KWU PWR plant installed at Biblis (Germany).

This falcility was designed, released and operated at the Joint Research Centre (JRC) of Ispra

Establishment, and it was one of the largest high pressure integral systems of this kind operating in

Europe.

A sketch of the primary circuit of the facility is reported in Fig. 1. It essentially consists of the

following parts (refs. [9] and [10]):

- a pressure vessel containing the heated bundle consisting of 64 directly heated rods arranged in

8x8 square matriL A cosine shaped axial power profile is obtained trough seven different

thickness of the hollow cylinder simulating the rods. Nominal heating power is 5.3 MW. Four

bypass flow paths are realized in the vessel region: three between upper plenum and downcomer

and one between lower plenum and upper plenum. The ones between upper plenum and

downcomer are obtained via gap in the connection hot leg-vessel, via "ad hoc" holes in the barrel

and via the upper head, respectively;

- a small vessel simulating the upper head of the PWR vessel;

- two loops, respectively called "INTACT" loop and "BROKEN" loop, the former representing the

three unbroken loops of the four-loops reference PWR plant, the latter simulating "broken" loop

in which pipe ruptures of various sizes can be mounted at different locations. The two loops are

equipped with equal recirculation pumps which, during steady-state, run at different velocities to

achieve rightly scaled flow rates. In each loop a steam generator is containing components such as

inverted U-tubes, an annular downcomer and coarse and fine steam separators modeling the

geometry of the reference plant. The exchanged power in the two steam generators, at the

nominal operating conditions, is of 1.32 MW (8 U-tubes) and of 3.96 MW (24 U-tubes) for the

BROKEN and the INTACT loop, respectively;

- an active secondary loop system, shown in Fig. 2, containing two condensers simulating the

reactor turbines, the feed water pump and the auxiliary feedwater system,

- a pressurizer and surge line connectable to either the intact or broken loop;

- emergency core cooling system equipped with active High Pressure Injection System with up to 4

HPIS injection pumps, Low Pressure Injection System and a Passive Accumulator System, with

two accumulators, one in each loop.

The scaling criteria utilized in the LOBI-MOD2 facility led to the following characteristics:

- volume, primary circuit coolant mass flow and power input are scaled down from the referred

reactor values, by a factor of 712;

- in order to preserve the gravitational head the absolute heights and relative elevations of the

individual system components have been kept at reactor values with the exception of the

pressurizer, which is shorter in order to preserve the scaling ratio and maintain, at the same time,

an acceptable flow area.

The LOBI test facility was initially designed to simulate the thermalhydraulc scenario in a

Pressurized Water Reactor during Large Break Loss-of Coolant Accident (LBLOCA). Subsequent

modifications to the original LOBIWMODI facility, like a more accurate design of the secondary side

of steam generators, a new reactor pressure vessel and a greater number of thermocouples installed,

13
made LOBI/MOD2 well faced for simulation of a wide variety of Small Break LOCA (SBLOCA)

and special transients experiments.

The instrumentation system of the facility allowed the measurements of the main thermalhydraulic

parameters performed at the boundaries of the principal loop components and at the principal

sections of the pressure vessel and the steam generators.

The main measurement locations in the facility can be classified as follows:

"Loop pipes: performed within "measurement inserts" which contain the complete instrumentation

for each location. The "insert" can be "simple" or "complete". In the simple insert the

measurement of fluid and wall temperatures and absolute and differential pressure are performed.

The complete inserts also contain flow and density measurement devices. A distinction, in the

instrumentation available in the inserts, is made between vertical and horizontal pipes: the inserts

for horizontal flow are supplied with double instrumentation for temperature and flow

measurement in order to show eventual stratification phenomena in the pipe section.

" Reactor pressure vessel simulator: with absolute pressure taken in the upper plenum. Differential

pressure measurements are provided over all the main sections along the flow path of the pressure

vessel Mass flow information is provided by flow and density measurements in the core inlet box.

A second density measurement indicates voiding of the lower plenum. Fluid and wall

temperatures are measured in the more representative locations in the vessel

" Heater rod bundle: each heater rod is supplied with three thermocouples in the tube wall.

" Steam generators: measurements are provided of fluid temperatures, U-tubes wall temperatures

and differential pressure on the primary and secondary side.

" Pressurizer: fluid temperatures and pressure are measured and the surge line flow is obtained by a

full flow turbine. Differential pressure is measured over the surge line and over the height of the

pressurizer to monitor the filling level.

2.2 Test BL-44

The counterpart test is essentially a Small Break LOCA originated by a rupture in the cold leg

between the pump and the reactor vessel The break is "side oriented" in the pipe and has an area

equivalent, roughly, to 6 % of the main pipe area: the reference break diameter in the prototype plant

is 50 mm (2 "). The sequence of interventions of the various systems is typical of this kind of

transient in a plant: after the break occurrence, scram and pumps trip are provided, together with a

signal for isolating steam generators (feed water and steam line closure). Accumulators intervention

is foreseen when primary pressure below 4 MPa. After the accumulators emptying, the flow rate

from the break causes mass depletion from the primary system, leading unavoidably to core dryout.

Low pressure injection system actuation is foreseen after the occurrence of core dryout and is

effective in rewetting the rods

It should be noted that, owing to limitations in maximum power available in Bethsy and LstW the

initial conditions of the four experiments have been established at a core power around 10 % of the

reference reactor nominal power. Few relevant initial condition values are given in Tab. 1.

As already mentioned, in Spes and Lobi facilities the counterpart experiments have been repeated

utilizing the full power, in order to evaluate whether the transient evolution was affected by the initial

conditions.

The data given in Tab. 1 demonstrate that, in the four low power experiments, the choice was

made to preserve the initial value of the fluid temperature jump across the core (mass flow rate

reduced of the same amount as power) and to have the same hot leg temperature. In order to achieve

this, it was necessary to increase the initial temperature and pressure of steam generators with

respect to the nominal conditions.

The general purpose of the counterpart experiments (including the two full power experiments)

was to be part of the counterpart program. Relevant thermalhydraulic phenomena of potential

interest during the experiments are: mass distribution in the primary system, heat transfer with

secondary side with degraded primary conditions, including reversal of heat flux, loop seal behavior,

core heat-up and rewet, accumulators performance and stratification in horizontal pipes.

The transient setpoints imposed and resulting sequence of events for LOBI BL-44 test is reported

in Tabs. 2 and 3. The transient scenario can be derived from Figs. 3 and 4. In this test (as well as in

BL-34 experiment), the pressurizer is connected to the broken loop, because, as already mentioned,

the test is a counterpart of experiments performed in Lst, Bethsy and Spes facilities where this

configuration was adopted.

The accident can be subdivided into four main periods from a phenomenological point of view:

a) subcooled blowdown and first core dryout rewet (time from 0 to 204 s);

b) saturated blowdown and primary to secondary side pressure decoupling (from 204 s up to

accumulators emptying);

c) mass depletion in the primary loop (from accumulators emptying to the final core dryout);

d) intervention of low pressure injection system that quenches the core.

Phase a). Following the break the primary system pressure is subject to an initial fast decrease (0.1

MPa/s) up to the achievement of saturation conditions upstream the break; this occurs at about 80 s

into the transient. The sharp initial pressure decrease lead to scram, main coolant pump trip and

isolation of steam generators in the first 10 s of the transient. Pressurizer emptying occurs in about

25 seconds. During the phase a), U-tubes draining occurs in primary side (at about 90 s) for the loss

of natural circulation between core and downcomer through the steam generators: at this time the

saturation temperature in the primary loop is still few degrees higher than saturation temperature in

the secondary side.

The stop in natural circulation, essentially due to voiding and mass depletion in the upper zones of

the loop, causes manometer type situation in the primary loop piping: the steam produced in the core

17
partly flows directly in the break through the bypass and partly pushes down the level in the core, to

balance the liquid level present in loop seals. In this situation core dryout occurs at about 189 s in the

top level of the rods.

The loop seal clearing is present only in the intact loop (at about 197 s): pumps operation mode

and, particularly, the switch on of the pump locked rotor simulator valve in the broken loop only,

may be at the origin of the different behaviour of the two loops. Timing of occurrence of the

phenomena are different in BL-34 and BL-44 tests and justify their difference as far as the loop seal

clearing in broken and intact loop is concerned.

Phase b). Continuous core boil off and primary-to-secondary side pressure decoupling

characterize the first part of phase b). The core boil off (produced steam flows almost entirely to the

break) causes a second dryout at about 370 s at a pressure higher than the accumulators pressure (4

MPa); liquid level hold up in the broken loop seal occurs, starting from about 200 s, somewhat

limiting steam flow to the break. Probably the reverse speed of the pump (at -28 rpm during the

whole transient) contributes to the formation of liquid hold up in the broken loop seal, pump side. In

this period the heat transfer from secondary side to primary side is quite small compared with core

power, because the high void fraction in the U-tubes.

The accumulators intervention at 428 s causes the recovery of liquid level in the core and a

second rewet that is completed at about 551 s. The isolation of accumulators occurs at about 960 s:

in the period from 428 to 960 s the primary system mass increases, because the liquid flow rate

delivered by accumulators is larger than the break flow rate.

Phase c). The stop of accumulators injection (t = 964 s) causes another mass depletion period,

leading to the third dryout at about 1711 s into the transient, when the primary pressure was around

1 MPa. No other significant event occurs in this period, excluding the core level depression. When

the rods surface temperature reaches 800 K, the low pressure injection system is actuated (2066 s) in

the intact loop cold leg.

Phase d).The LPIS flow rate (0.4 kgls) is quite effective in causing the third core quench and in

recovering the facility. The quench front velocity is larger than 0.02 m/s and, at about 2200 s, the

core is completely recovered. Core refill occurs in this period. The test was terminated at 2350 s,

with pressure around 0.55 MPa.

3. ADOPTED CODE AND NODALIZATION

3.1 RelapS/Mod3.2 code

The light water reactor transient analysis code, RELAP5, was developed at the Idaho National

Engineering Laboratory (INEL) for the U.S. Nuclear Regulatory Commission (NRC). Specific

applications of the code have included simulations of transients in LWR system such as loss of

coolant, anticipated transients without Scram (ATWS) and operational transients, such as loss of

feed water, loss of offsite power, station blackout and turbine trip.

The Mod3 version of RELAP5 has been still developed by the INEL, but a consortium consisted

of several countries and domestic Organizations that were members of the International Code

Assessment and Application Program (ICAP) and its successor organization, Code Application and

Maintenance Program (CAMP), contributed to the development and the validation process.

RELAP5/Mod3.2 code, refs. [11] and [12], is based on a non-homogeneous, non-equilibrium

set of six partial derivative balance equations for the steam and the liquid phase. A non-condensable

component in the steam phase and a non-volatile component (boron) in the liquid phase can be

treated by the code. A fast, partially implicit numeric scheme is used to solve the equations inside

control volumes connected by junctions.

In particular, the control volume has a direction associated with it that is positive from the inlet

to the outlet. The fluid scalar properties, such as pressure, energy, density and void firacon, are

represented by the average fluid condition and are viewed as being located at the control volume

center. The fluid vector properties, i.e. velocities, are located at the junctions and are associated with

mass and energy flow between control volumes. Control volumes are connected in series using

junctions to represents flow paths.

Heat flow paths are also modeled in a one-dimensional sense, using a staggered mesh to

calculate temperatures and heat flux vectors. The heat structure is thermally connected to the

hydrodynamic control volumes through heat flux that is calculated using a boiling heat transfer

formulation. The heat structures are used to simulate pipe walls, heater elements, nuclear fuel pills

and heat exchanger surfaces.

Several new models, improvements to existing models and user conveniences have been added.

The new models include:

* the Bankoff counter-current flow limiting correlation;

" the ECCMIX component for modeling of the mixing of the subcooled emergency core cooling

system liquid and resulting interfacial condensation;

" a zirconium-water reaction model to model the exothermic energy production on the surface of

zirconium cladding material at high temperature;

" a surface to surface radiation heat transfer model with multiple radiation enclosures defined

through user input;

" a thermal stratification model.

3.2 General criteria adopted for the code models

A detailed nodalization reproducing each geometrical zone of the loop has been developed: in

principle it is suitable for different types of transients.

The general methodology followed is described in refs. [12] and [13]. Being used, in this case,

the Relap5/Mod3 code, great care is given to the information contained in the specific user manual.

23
Nevertheless, it should be noted that this information alone is generally not exhaustive for the

development of an adequate set of input data. So, few supplementary criteria, to those reported in

the manual, have been fixed, as result of experience, in the attempt to set up a "homogeneous"

nodalization, that is to avoid imbalance in the distribution of hydraulic and thermal meshes. Of

course, the achievement of this objective, requires a good user knowledge of the reference facility

characteristics. Moreover, the prevision of the phenomena to be simulated in the calculation can also

have a role in this context. Compromises apply in the choice of number of nodes: on the one hand

there is the need to develop a model adherent to the geometric and material particularities of the

physical system, on the other hand computer capabilities (essentially CPU time) limit the maximum

number of nodes.

Two limits have been fixed for the linear dimension of nodes: all the volumes should have their

flow lengths comprised between 0.5 and 1.0 m (with the exception of core stack, much more

detailed, of the descending zone of the SG U-tubes and of the pressurizer and accumulator surge

lines, nodalized by 2.0 m length nodes). With regard to conduction heat transfer, the distance

between neighboring mesh points inside structures must be less than 5 mm in each case, up to the

lower limit of few tenths of mm used for heated rods and steam generator U-tubes. In the subdivision

of volumes and slabs the position of instrmmentation has been considered.

The following choices have been made with regard to code options:

* thermodynamic non-equilibrium is allowed in all control volumes;

" the smooth area change for all the junctions where it is allowed (i.e. excluding the motor valves);

* the stratification option is used in the junctions of the hot legs and cold legs horizontal parts.

3.3 LOBI/MOD2 nodalization description

The LOBWIMOD2 nodalization is shown in Fig. 5. The correspondence between the zones of the

facility and the nodes of the code model are exposed in Tab. 4. In this table the facility is divided in

general zones, composed by single components, reported in the table according to flow paths in

nominal conditions. The number and the type of the hydraulic nodes, corresponding at each single

component of the facility, are indicated in the table itself

Hereafter some significant aspects of the nodalization development are summarized.

Primary system model

The vessel model consists of 29 hydraulic components which are connected through 48 junctions.

The heat structures utilized in the RPV model are made up of 47 heat slabs, distinguished in:

* 13 active structures for the heaters;

* 30 heat slabs for the vessel wall;

* 4 internal non-active structures.

In the vessel model all the bypass flow paths, reported in the facility description, have been

modeled:

" bypass from downcomer top to upper plenum via holes simulated by junctions 430-02 (bypass

flow rate equal to 0.35 kg/s);

" bypass from downcomer top to upper plenum via gap in the connections with the hot legs

simulated by junctions 500-03 and 700-03 (bypass area strictly dependent by thermal expansion of

the structures, thus the bypass flow rate valuable, with a large uncertainty band, roughly equal to

1 kg/s):

" bypass from downcomer top to upper head simulated by node 440-01 with bypass flow rate

roughly equating to 0.3 kg/s.

24
Both the broken and the intact loop represent with geometrical fidelity the real hydraulic

configuration of the experimental facility. Notwithstanding this, the degree of detail is properly

increased in the BL, where are localized, in transient conditions, the most important thermalhydraulic

phenomena.

Intact and broken loop are so simulated:

* 53 nodes and 54 junctions for the IL;

* 55 nodes and 57 junctions for the BL.

The accumulators are schematized in both loops and are connected to the respective cold legs.

The localized pressure drops, due to the "locked rotor resistance simulator" is introduced in the

loop by the motor valve 747 component.

The tine dependent volumes 742, 603 and 602, connected with the primary system through the

time dependent junctions 744, 601 and 604 respectively, simulate the pump cooling system. Each

system is realized with cold water injection in the pump and consequent water draining from the

lower plenum.

Two additional systems can be noted in the pressurizer nodalization:

* a time dependent volume and related valve (components 541 and 542);

* a time dependent junction and related time dependent volume (components 531 and 534).

Both are control systems. The former system allows the primary side pressure to remain constant

in a steady-state period. The latter system maintains at an assigned value the liquid level inside the

pressurizer. The temperature of the fluid possibly injected by this system corresponds to the

saturation conditions inside the pressurizer. A check has been made to verify that the flow rates and

the energy exchanged between this system and the primary circuit are well below the reference flow

rate and energy values of the primary side. Finally the black structures inside the pressurizer model

represents the internal heaters.

Secondary system

The secondary side nodalizations of the two steam generators are very similar, both concerning

the hardware of the facility and the control systems (23 nodes, 23 junctions and 45 heat slabs).

Four zones can be recognized in each steam generator:

1) the downcomer, consisting of a single stack of nodes that simulates a multitubular geometry,

2) the riser zone, essentially including the U-tubes;

3) the top of the vessel, including the separator, the dryer and the steam dome regions;

4) the steam line downstream the dome of each SG is simulated with a time dependent volume (829

for IL and 929 for BL) connected to the dome by a time dependent junction (828 for IL and 928

for BL).

The degree of detail of the nodalization is commensurate to what considered in the primary loop.

In particular, the heights of the riser volumes are the same as the minimum between the heights of

the rising and the descending corresponding nodes of the primary side U-tubes.

The components 815-01 for IL and 915 for BL simulates the separators in the secondary sides

that are necessary in the code model in order to achieve quality equal to 1 in the steam domes.

A relatively large number of control volumes are connected with the steam generators; the

following functions are accomplished:

" feed water injection: time dependent volumes 832 (IL) and 932 (BL); time dependent junctions

833 (IL) and 933 (BL);

" AFW injection: time dependent volumes 836 (IL) and 936 (BL); time dependent junctions 837

(IL) and 937 (BL);

* safety system: time dependent volumes 826 (IL) and 926 (BL), simulating the safety tanks; trip

valves 825 (IL) and 925 (BL), simulating the safety valves;

" components 824-01 and 823, for IL, and 924-01 and 923, for BL, simulate the control system

that assures constant pressure during a steady state period.

25
The geometrical features of the piping and system connected with SGs are not simulated (e.g.

feed water lines, pre-heaters, steam lines - including condenser - etc.), because this is not relevant for

the prediction of the transients of interest.

The utilized code resources for the LOBIIMOD2 nodalization are summarized in Tab. 5. In

particular, the number of hydraulic components and of the heat structures are here reported. .-

3.4 Nodalization qualification

A nodalization representing an actual system (Integral Test Facility or plant) can be considered

qualified when:

- it has a geometrical fidelity with the involved system;

- it reproduces the measured nominal steady state condition of the system;

- it shows a satisfactory behavior in time dependent conditions.

Taking into account these statements, a standard procedure to obtain a "qualified nodalization"

has been defined, ref. [14].

The qualification process consists of two main phases:

1) steady state level: the nodalization is qualified against data available from nominal stationary

conditions measured in the simulated system. To this aim:

a) relevant geometrical parameters of the facility (e.g. volume, heat transfer area, elevations,

pressure drops distribution etc.) are compared with the input data and the differences

among them must be acceptably small. The adopted acceptability criteria are reported in the

first part of Tab. 6 (see also Fig. 6);

b) the nominal steady state conditions are simulated with a code running (a hundred seconds

time interval is considered acceptable to reach correct steady state values); significant

parameters are selected and compared with the measured results. A parameter is considered

as significant when it is of major relevance in determining the plant behavior and can be

reliably measured. The adopted acceptability criteria for this step are reported in the second

part of Tab. 6 (see also Fig. 7).

2) transient level: the nodalization is tested in time-dependent conditions reproducing the available

experimental transients. This phase also includes the procedure for the qualitative and the

quantitative (through the application of the FFT based method) evaluation of the code accuracy,

necessary to demonstrate the acceptability of the code transient performance. The demonstration

of the quality of the nodalization at the transient level, before application to the reference

calculation (BL-44 in this case), involves at least one among the following steps:

a) perform a "K, scaled" calculation aiming at the comparison between the nodalization

performance and experimental data in another facility (proper scaling factors must be

adopted to fix initial and boundary conditions);

b) compare results of the nodalization with experimental data different than those object of the

reference calculations (these can be operational transient data in the case of a Nuclear

Power Plant);

c) compare the results of the nodalization with calculations data coming from a previously

qualified nodalization.

The idea of the "Kv-scaled calculation" (item a) comes from the objective to comparing

calculated data with experimental data before adopting any nodalizations (i.e. including NPP

nodalization) for any kind of calculation (code assessment, licensing, etc.). In this frame, adopting

proper scaling criteria (time preventing, volume/power scaling)a comparison can be made between

predicted and experimental data in the area of PWR and BWRI This must be used to detect

nodalizations and user choice inadequacies. Correction of errors or deficiencies leads to a "on

transient" qualified nodalization ready to be used for other purposes.

The acceptability constraints for the FFT (i. e. 0.4 for Average Accuracy and 0.1 for the primary

pressure) must be fulfilled in any case.

The qualification process, summarized above, has been applied to the nodalization of Lobi

facility.

As concerns the first phase (steady state level), the steady state acceptability criteria previously

defined (reported in Tab. 6) have been verified, in particular, the comparison between the calculated

31
and the measured volume vs. height curve and the distnrbution of pressure drops along the length are

reported in Figs. 6 and 7, respectively.

The second part of the qualification process (transient level) has been conducted through the

step b) and c) described above: in the first case the International Standard Problem 18, ref [15], has

been in considered, while in the second case the previous simulation with the version Relap5/Mod2,

ref [5], has been utilized (see also below).

It is to be mentioned that the application of the FFT based methodology has been exhaustively

performed in the Relap5/Mod2 simulation of BL-44 [16] and it was not repeated in a systematic way

for the RelapS/Mod3.2 simulation. No important differences related to any of the finding of the

Relap5/Mod2 analyses are expected.

4. ANALYSIS OF POST-TEST CALCULATION RESULTS

Three main calculation types can be distinguished in a meaningful code assessment process:

a) 100 s steady state;

b) reference calculation results;

c) results from sensitivity studies.

It may be noted that item a) may constitute a part of the nodalization qualification process,

described in the previous chapter, however, the fulfillment of criteria reported in Tab. 6 is necessary

each time a new experiment is considered and before starting transient calculations by using the

previously qualified nodalization.

The reference calculation results, item b), must outcome from the qualified nodalization and

satisfy qualitative and quantitative accuracy related criteria. The reference calculation is not "the

best" calculation achievable by the code. In order to get the reference calculation, boundary and

initial conditions of the considered experiment (i.e. input data for the reference calculation) may be

changed within their uncertainty ranges; if a user choice is introduced (e.g. changes in noding detail),

its validity and acceptability must be checked by repeating the nodalization qualification process.

Sensitivity analyses, item c), must be carried out to demonstrate the robustness of the

calculation, to characterize the reasons for possible discrepancies between measured and calculated

trends that appear in the reference calculation, to optimize code results and user option choices, to

improve the knowledge of the code by the user.

The attention is focused hereafter toward the analysis of the reference calculation results, item

b), considering that steady state calculation, item a), is part of the nodalization qualification process

and sensitivity analyses, item c), can be designed following the analyses at the previous step. Typical

results are provided in relation to the three steps.

When calculating the quantitative accuracy, twenty-one time trends have been selected in

relation to which experimental data exist: these are assumed to be the minimum number of measured

quantities that fully describe the experimental scenario. The related list is given in the first column of

Tabs. 11 and 13.

When calculating qualitative accuracy, including the comparison between time trends, reference

is made to the same list (e.g. Apps. 1 and 2) of Tab. 13; the following quantities have been added to

the comparison: pressure drop across DC-UH bypass, pressure drop in the U-tubes ascending leg

(also a measure of liquid hold-up in the U-tubes), core inlet flow rate, pressure drop in cold leg, mass

flow rate in SG downcomer, hot leg mass flow rate. Fig. 29 has been added to give an overall view

of the system performance (primary and secondary pressure together).

4.1 Steady State calculations

A steady state calculation, by running the code with the TRANSNT' (transient) option for 100 s

has been completed. This constitutes the final step of the nodalization qualification process at steady

state level.

The related results are shown in Tab. 7 and in App. 1. In both cases, resulting values are

compared with experimental data. In the case of Tab. 7, for completeness, the data calculated by

Relap5/mod2 are included as taken from ref. [5].

It may be noted that the data in Tab. 7 deal with most of the parameters imposed for the

nodalization qualification process (Tab. 6): the values in the table have been taken from the code

output at 100. s. The time trends above identified are part of the App. 1, numbering of figures is

different owing to the obvious lack of time trends dealing with ECC and break flow rates.

The analysis of data brings to the following conclusions:

35
- the criteria for nodalization qualification are fulfilled, though the complete comparison between

data in Tab. 7 and in App. 1 with acceptability criteria has not been done owing to the lack of

experimental data; in addition, some of the criteria can be matched by considering sums or

combinations of values from Tab. 7 (e.g. the primary circuit power balance can be obtained by

considering data at items 1, 4, 14, 16 and 17); still, the error on bypass flow rate, can be better seen

by considering the errors in fluid temperatures owing to the fact that the direct experimental

information about bypass flow rate is uncertain (measurement error not available);

- the calculated values are stable as it results from Figs. I to 26;

- differences between Relap5/mod2 and Relap5/mod3.2 codes results are negligible;

- discrepancies between measured and calculated values of heater rod temperatures, come from the

position of thermocouples and from generic experimental error (the calculation result refer to the

surace, the experimental data are taken slightly inside the surface, the error almost disappears at

low linear rod power, during the transient);

- discrepancies in the case of accumulators pressure, primary side mass and vessel riser level, are

within the acceptability criteria, considering the experimental uncertainties (about ± 0.1 MPa for

accumulators pressure and ±:3 %for primary mass);

- the discrepancy in the cases of pressure drops is attributed to the experimental error and to the

position of the measurement pressure taps not accounted for by the calculated results;

- the discrepancy related to the recirculation mass flow rate in the steam generator, can also be

originated by a measurement error, however, in this case tuning or adjustments of steady state code

results was considered unnecessary owing to the low influence that this parameter has in the

selected transient (early main coolant pump and feedwater trips occur).

4.2 Reference calculation results

The post-test calculation was performed starting from the input deck suitable for RelapSIMod2.

A 'blind' post test was performed by Relap5/Mod3.2 constituting the reference calculation for this

study (label B44E); the related time trends and significant single valued parameters are reported,

together with experimental data, in App. 2 and in Tab. 8, respectively.

A comprehensive comparison between measured and calculated trends or values was performed,

including the following steps:

a) comparison between experimental and calculated time trends on the basis of the 29 variables

introduced above (App. 2);

b) comparison between values of quantities characterizing the sequence of resulting events, Tab. 8;

c) qualitative evaluation of calculation accuracy on the basis of the phenomena included in the CSNI

matrix, ref [17], as given in Tab. 9;

d) qualitative evaluation of calculation accuracy on the basis of the Relevant Thermalhydraulic

Aspects (RTA, also used for code uncertainty derivation, e.g. ref [6]), as given in Tab. 10;

e) quantitative evaluation of calculation accuracy, utilizing the FFT based method (FFTBM),

described in refs. [8] and [16], see also App. 1 in ref.[20], as given in Tab. 11.

Comments related to items a) and b) are given below, distinguishing groups of homogeneous

variables, while the discussion about items c), d) and e) is given in sect. 4.2.1.

Absolute Pressures

The primary system pressure is quite well predicted by the code and the phenomenological

phases (e.g. subcooled blowdown, saturated blowdown and steam flow from the break) can be easily

recognized from the calculated time trend (Fig. 8 below and Fig. 1 in App. 2). During the saturated

blowdown (from about 50 s up to 500 s) the calculated pressure is higher than the experimental one.

This discrepancy is connected with the overestimation of the secondary side pressure (fig. 2 of App.

2): heat losses to the environment appear to have a substantial role in this case.

36
The accumulator generally follows the primary pressure; time of accumulator actuation is

reasonably well predicted, together with the time accumulator stop.

Fluid temperatures

Measured and calculated fluid temperatures are compared in Figs. 4, 5, 6, and 8 of App. 2, the

last one related to the steam generator and the other ones related to the primary circuit.

Core inlet and outlet fluid temperatures are qualitatively well predicted (Figs. 4 and 5). The

predicted core outlet fluid temperature presents two peaks in correspondence to the two core level

depressions. The superheating is larger than in the experiment and the position of the thermocouple

strongly affects this time trend. This is specifically true for the upper head fluid temperature where a

very high superheating is measured; in this case, it seems evident that the thermocouple gives a

measure of the structural mass temperature starting from about 400 s into the transient, i.e. following

the emptying of the upper head.

Mass flow rates and residual mass

The measured values of break flow rate (Fig. 9 below and Figs. 7 and 9 in App. 2), the ECCS

flow rate (Fig. 10 below and Fig. 10 in App. 2), core inlet (Fig. 25 in App. 2), hot leg mass flow rate

(Fig. 28 in App. 2) and the steam generator downcomer flow rate (Fig. 27 in App. 2) are compared

with the respective calculated trends.

Break flow rate is well predicted; up to 500 s into the transient it is slightly underpredicted, but

the related error can be considered within the uncertainty bands.

The calculated ECCS flow rate is in a good agreement with the calculated trend; it can be noted

the overprediction of the flow rate delivered by accumulators and the delay of the LPIS intervention,

due to the delayed occurrence of the third dry out.

The residual mass in primary side is well predicted (Fig. 14 of App. 2); the calculated value is

higher than the experimental one for all the transient, but the difference can be considered within the

experimental uncertainty band.

Pressure drops

Pressure drops between different points of the primary circuit are considered in the comparison,

e.g. Figs. 17, 19, 20, 22, 23, 24 and 26 in App. 2. All of the comparisons, with different extent,

suffer of the limitation already explained in sect. 4.1 (pressure taps not coincident with the center of

the volumes of the nodalization).

Pressure drop in the intact loop is reasonably well predicted by the code; this is not the case for

the broken loop, because the code predicts the occurrence of loop seal clearing (not occurred in the

experiment) at about 60 s. This confirms the difficulty, already emphasized in previous analyses [ref.

5] in correctly predicting a critical phenomenon like loop seal clearing. The distribution of pressure

drops in the initial steady state, both direct and reverse (in this last case calculated data can not be

qualified), are responsible for the misprediction of loop seal clearing phenomena. This is a well

known limitation, resulting from several code applications to SBLOCA analyses and in all the cases

assessed by the present authors it does not affect the code capability in predicting the overall

transient scenario.

In the case of steam generator inlet plenum to U-tubes top and downcomer to upper head

bypass, the pressure drops are very well predicted by the code.

Levels

The pressurizer level (Fig. 11 below and Fig. 21 in App. 2) is well predicted in the calculation,

testifying the good prediction of the subcooled blowdown flow rate.

Core collapsed level constitutes a critical quantity during this experiment, as the level variations

are directly connected with the occurrence of core dryout. The trend of this variable is strongly

37
affected by the distribution of pressure drops along the loop that also influence the occurrence of

threshold phenomena like loop seal clearing.

The calculated core level is in a quite good agreement with the experimental trend (Fig. 12

below and Fig. 15 in App. 2). The first core level depression is not predicted by the code: this

discrepancy is connected with the bypass flow paths inside the vessel, that can facilimte the steam

discharge form the upper plenum and limit the steam binding effect on the core level. Pumps

operation and, in particular, uncertainties in the rotation speed as a function of time and in the head

as a function of the rotation speed (homologous curves) can have a role in this connection.

Rod Surface Temperatures

When analyzing the rod surface temperature trends, the three-dimensional situation in the core

must be considered, as described into detail in ref [4].

Representative experimental data at three core levels have been selected for the present

comparison, distinguishing in the axial sense, the core bottom, the core middle and the core top

regions (Figs. 11 to 13, respectively in App. 2, and Fig. 13 below related to the top region).

Predicted rod surface temperature trends follow well the measured values. The first dryout is not

predicted by the code and the reason is connected with the bypass flow paths into the vessel (see

above). The second dryout situation is well predicted by the code; it can be noted that, in

correspondence of the high core level, the quenching is delayed of about 200 s: minor uncertainties

connected with the average power assigned to the involved structure and coming from the position

of the thermocouples, can be associated with the considered discrepancy. The occurrence of the final

dryout is reasonably well predicted.

4.2.1 Qualitative and quantitative accuracy evaluation

Oualitative accuracy

The qualitative accuracy evaluation here discussed is based upon a systematic procedure

consisting in the idenfication of phenomena (CSNI list) and of RTA. In both cases five levels of

judgment are introduced (E, R, MK U, and -) whose meaning is detailed in the notes of Tab. 9 and in

App. 1 of ref. [20]. The related results are reported in Tabs. 9 and 10, where for completeness the

information related to Relap5/mod2 results are given.

A positive overall qualitative judgment is achieved if UJ is not present; in addition, the

parameters characterizing the RTA (i.e., SVP = Single Valued Parameter, TSE = parameter

belonging to the Time Sequence of Events, IPA= Integral Parameter and NDP = Non Dimensional

Parameter) give an idea of the amount of the discrepancy.

In the present case the following conclusions could be reached:

a) no •U' mark is present;

b) all RTA of the experiment are present in the calculated data

c) the accuracy evaluation by adopting RTA and Key Phenomena, supports the conclusion that

the calculation is qualitatively correct.

Quantitative Accuracy

The positive conclusion of the qualitative accuracy evaluation, makes it possible addressing the

quantitative accuracy evaluation. To this aim a special methodology, developed at University of Pisa,

and widely used has been adopted.

The methodology is based upon the use of the Fast Fourier Transform (e.g. ref [19]); its main

features are detailed in App. 1 of ref. [20].

The results qf the application of the method are given in Tab. 11, where again the information

related to Relap5/mod2 calculation is given too. The conclusions from the quantitative accuracy

evaluation analysis are as follows:

a) the achieved results are well below the acceptability threshold both in relation to the overall

accuracy (AA = 0.29 compared with the acceptability limit of 0.4) and the primary system

pressure accuracy (AA 0.05 compared with the acceptability limit of 0.1);

b) the achieved results appear slightly better than those obtained by Relap5/mod2.

Definitely, the documented reference calculation is acceptable from the code assessment point of

view-, i.e. the code is positively assessed in relation to its capabilities to predict this kind of transient.

4.3 Sensitivity calculations

Considering the extensive sensitivity studies carried out in the frame of the analyses of the Spes

tests SP-SB-04 (ref [20]) and SP-SB-03 (ref. [21]) and the Lobi test BL-34 (ref. [22]) and the

acceptable results obtained in the present analysis, it was decided to carry out only two sensitivity

studies, focused towards the accumulators behavior and the evaluation of effects of the modeling of

the bypass flow paths between the upper head and the downcomer.

The characteristics of the performed calculations can be drawn from Tab. 12, together with the

results of the FFT methodology application (overall calculation and primary pressure). The summary

of the FFT results related to all the parameters for all the performed sensitivity calculations are given

in Tab. 13. The comparison between calculated and measured trends for each sensitivity analysis is

reported in Appendix 3 and in Figs. 14 to 17.

As expected, the influence of the performed changes is limited, considering the assigned range of

variation of the parameters modified in the analyses; this fact is confirmed by the FFT results (see

Tab. 13), that are very similar to those obtained for the reference calculation.

5. CONCLUSIONS

The analyzed transient (BL-44) is a small break LOCA experiment originated by a rupture in the

cold leg of the broken loop of the LOBIMOD2 facility. No high injection system is provided during

the test; three dryout situations occur: the first one, at about 189 s into the transient, is quenched by

an intrinsic mechanism like loop seal clearing; the second one is quenched by the intervention of the

accumulators and the third one is recovered by the actuation of the low pressure injection system.

A qualified Relap5/Mod3.2 nodalization has been used for the analysis. The comparison between

the code prediction and the experimental data leads to the conclusion that the code is able to predict

all the significant aspects of the transient, with the exception of the first dryout-rewet phenomenon.

The present one constitutes the third of four analyses related to Small Break LOCA having

similar characteristics (counterpart tests), e.g. refs. [20] and [21]

Basically, the main conclusions achieved in previous analyses are confirmed by the present one:

* the Relap5/Mod3.2 has full capability in predicting the Relevant Thermalhydraulic Aspects that

characterize the transient;

* the above conclusion has been reached following a detailed procedure, including qualitative and

quantitative evaluation of accuracy,

* a limited set of sensitivity calculations has been carried out in the present case, considering the

reasonable agreement reached in the reference calculation and the results of sensitivity analyses

performed and documented in the above mentioned studies: the here considered sensitivi studies

do not bring important advances in understanding code capabilities;

* minor discrepancies between measured and calculated trends, judged to be reasonable and

acceptable, have been discussed in the text.

10. SUPPLEMENTARY NOTES

11. ABSTRACT r" wods @ iva)

The present document deals with the RELAP5/MOD3.2 analysis of the small break LOCA experiment BL-44 performed in

LOBI1MOD2 facility. LOBiMOD2 was a PWR simulator (Integral Test Facility) installed at JRC Joint Research Center) in Ispra

Establishment (I). Volume scaling and core power scaling factors are 1/71Z with respect to the KWU Siemens 1300 MWe (3900

MWt) standard reactor. The experiment is originated by a small break in the cold leg (2" equivalent break area in the plant) without

the actuation of the high pressure injection system. Low pressure injection system actuation occurs after core dry-out and

accumulators intervention is foreseen when primary pressure falls below 4 MPa. The RELAP5 code has been extensively used at

University of Pisa; the nodarztion of LOBI facility has been qualified through the application of the version RELAP5AAOD2 to the

same experiment and another test performed in the same facility. Sensitivity analyses have been addressed to the influence of

several parameters (Ike discharge break coefficient, lime of accumulators start, etc.) upon the predicted transient evolution.

Qualitative and quantitative code calculation accuracy evaluation has been performed.
