ABSTRACT

The present document deals with the Relap5fMod3.2 analysis of the small br.!ak LOCA

experiment SP-SB-04 performed in SPES facility.

SPES is a PWR simulator (integral Test Facility) installed at SIET center in Pia::enza (IT).

Volume scaling and core power scaling factors are 1/427, with respect to the Westinghouse 900

MWe 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. The test starts from full power

and is the counterpart of the test SP-SB-03, that started at an initial power roughly equal to 10%

of nominal power. Low pressure injection system actuation occurs after core dry-out.

The Relap5 code has been extensively used at University of Pisa; the nodalizatic'n of SPES

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 assessme-nt and validation of large thermaihydraulic codes and the accuracy

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

of international research programs, such as those organized by the Committee on tfl.e Safety of

Nuclear Installation (CSNI) and the Code Application and Maintenance Program (CAMAP).

Solution of these problems would ensure the effectiveness of engineered safety fceatures 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, refis [1] and [21.

The execution of the experiments in Integral Test Facilities simulating the be'aavior 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 offnormal 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 transierit 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 influe~nce 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. [31, respectively available at the European Community Joint Research Center of Ispra

(I), at STET in Piacenza (I), at CENG in Grenoble (F) and at JAERI in Tokai-Miira (3). The

selected experiment is a small break LOCA originated by a rupture in the cold li-g, 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 conditio -is, 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 the one hand the Relap5

system code (Mod12 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 oif 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 and with the qualification of Relap5IMod2 nodalization -used for the

post test analyses, refs. [ 41 and 151, 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 Relap5IMcid3.2 of the

high power small break LOCA counterpart test carried out in SPES facility (SP-SB-04)..

So, the purpose of this report is to evaluate the performance of the Relap5IMod3.2 also in

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

systematic qualitative and quantitative accuracy evaluation has been completed. The quantitative

analysis has been performed adopting a method (ref. [7]) developed at DCMN, which has

capabilities in quantifying the errors in code predictions related to the measured experimental

signal-, the Fast Fourier Transform (FF1') is used aiming at having an integral represenlation of the

9
code calculation discrepancies (i.e. error between measured and calculated time trends) in the

frequency domain.

The qualitative accuracy evaluation, based on the selection of relevant thermaihydraulic

aspects is a prerequisite to the application of the FFT based method.

It can be noted that the main purpose of the high power test (SP-SB-04) was to evaluate the

influence of the initial conditions (in particular, high power, high mass flow rate and loss steam

generator pressure) upon the evolution of the mentioned small break LOCA transient. The

comparison of the two experiments, SP-SB-04 and SP-SB-03 (low power test with properly

scaled boundary and initial conditions, see also ref. (8]), led to the conclusion that, apart from the

first 200 s of the transient, the key phenomena are the same and occur almost at the same time.

2. DESCRIPTION OF THE EXPERIMENT

2.1 SPES facility

The SPES (Simulatore PWR per Esperienze di Sicurezza) Integral Test Facility., ref. [9], is

designed to simulate the whole primary circuit, the relevant parts of the secondary circuit (steam

generator secondary sides, main feed water lines up to the isolation valves, main steam lines

upstream the turbine valves), and the most significant auxiliary and emergency systems

(charging and let-down system, safety injection system, including high pressure and law pressure

system, accumulators, emergency feed water system, steam dump and so on) of the Italian

Standard Nuclear power plant (PWR-PUIN, Westinghouse 312 type, 3 loops, 2775 MvWth core

power)..

The basic design choices of the facility are the following:

* three active loops to simulate a three loops reactor;

* design pressure 20 M~a, design temperature 910 K; this choice allows the execution of tests

with primary pressure over the reactor design pressure (17.2 MWa);

* electrical heating of the power channel: 97 electrically heated rods, with uniform flux (local

hot spots can be simulated by means of three rods with a peaking factor of 1. 19);

* Maximum channel power corresponding to about 140% of the reactor nominal power; this

choice allows the simulation of reactor power excursions;

* volume scaling factor and power scaling factor (nominal power about 6.5 MW) equal to

1:427;

" the height of all the components is the same as in real plant, except for the pressurizer which

is shorter, in order to preserve the volume sealing ratio and to maintain at the same time an

acceptable flow area.

A sketch of the primary and secondary loops, is reported in Fig. 1, while Fig. 2 shows a

simplified flowsheet of the facility.

In the SPES rig 375 measurement points are available, providing a large set of both direct

physical quantities (absolute and differential pressure, temperature, voltage, etc.) and derived

physical quantities (void fraction, mass velocity, quality, etc.).

Various kinds of transducers are located in the SPES facility (thermocouples, heated

thermocouples, pressure transmitters, differential pressure transmitters, densitometers, void

fraction probes, Venturi tubes, turbines, catch tank), supplying the following paramete.-.s:

* temperature

2.2 Test SP-SB-04

The experiment SP-SB-04, ref. [9], is a small break LOCA originated by a rupture in the cold

leg, without high pressure injection system but with accumulators active and low pressure

injection system intervention.

The break is located between the pump and the vessel, it has an area equivalent, roughly, to

the 6 % of the area of the main pipe: the reference break diameter in the prototype plant is about

50 mm (2").

The design of the test has been made at University of Pisa, considering the counterpart tests

in facilities like BET.HSY, LOBI and LSTF, e.g. ref. [3]. The activity is documented in ref. [4].

The sequence of the main imposed and resulting events for SPES test SP-SB-04 are given in

Tabs. 1 and 2, respectively. The transient scenario can be also derived from Figs. 3 and 4.

From a phenomenological point of view, the accident can be subdivided into four main

periods:

a) subcooled blowdown and first core dry out-rewet (time from 0 to 132 s);

b) saturated blowdown and primary to secondary side pressure decoupling (from 132 s up to

accumulators emptying);

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

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

Phase a) Following the break the primary system pressure is subjected to an initial fast

decrease (0.1 MIPa/s) up to the achievement of saturation conditions upstream the break. As a

consequence of the depressurization at time t--7.5 s the scam is actuated, the pumps coastdown is

initiated, the steam generators are isolated, the MEFWIV are stopped with the same signal and with

8 s of delay. The steam generators isolation causes the secondary side pressure increase without

reaching the relief valve opening set points. Pressurizer emptying occurs in about 17 seconds.

During the first phase, natural "circulation between core and downcomer through the steam

generators develops up to the time when U-tubes draining occurs in the primary side: at this time

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

in 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 partly flows directly to the break through the bypass and partly pushes down

the level in the core to balance the liquid level present in the loop seals. In this situation a little

core dry out occurs. The rod cladding temperature excursion occurs only at the intermediate level

and in a rod that is not a hot rod (the radial peak factor is 1.19). The temperature excursion is

about 15 K and its time duration is less than 10 s, so we can explain this event as due to a

localized effect of fluid stagnation when the core flow rate is very low. The rod temperature

excursion ends when loop seals clearing starts (at about 132 s) in the broken loop.

After a more or less complete loop seal clearing in the three loops, a sufficient liquid mass is

present in the core to cool the rods.

Following the above events (especially broken ioop seal clearing), a large amount of steam is

present upstream the break and an important break flow rate decrease takes place.

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

characterize the first part of phase b). The core boil off causes a second smooth *level decrease at

a pressure higher than the accumulator pressure (4.22 MWa). In this period the heat transfer from

secondary-to-primary side is quite small compared with core power, because of the high void

fraction in the U-tubes.

14
The accumulator intervention at 334.5 s causes the recovery of the liquid level in the core and

prevents conditions for a second dry-out.

The isolation of accumulators occurs at about 1000 s: in the period from 334.5 s to 1000 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 second accumulator injection (t = 978 s) causes another rmuss depletion

period, leading to the second dry-out at about 1234 s into the transient, when thco pressure is

around 1 MWa. No other significant events occur in this period, excluding thc core level

depression. When the rod surface temperature reaches 697 K the low injection pressure system is

actuated (1468.5 s) in the cold leg of the two intact loops. Phase d) Th PSfo ae(.9k/or each intact loops) is quite effective in causing the

core quench and in recovering the facility. The quench front velocity is larger than 0. 02 m/s and,

at about 1450 s, the core is completely recovered. Core refill occurs in this period. Th1e test was

terminated at 1637 s with pressure around 0.77 M~a.

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 Commnis5 ion (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 offisite power, station blackout and turbine trip.

The Mod3 version of RELAP5 has been still developed by 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 validation process.

RELAP5/Mod3.2 code, refs. [10] and [11], is based onl a non-homogeneous, non-equilibriumn

set of six partial derivative balance equations for the steam and the liquid phase. A noncondensable 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 lo 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 fraction,

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 betweeti control volumes. Control volumnes are connected

in series using junctions to represents flow paths.

Heat flow paths are also modeled in a one-dimrensional sense, using a staggere.d 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 emnergency 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 d-,veloped: in

principle it is suitable for different types of transients.

The general methodology followed is described in refs. [111I and [ 121. Being used, in this

case, the Relap5/Mod3 code, great care is given to the information contained in the s:pecific user

19
manual. 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 lim-it of few tenths of mm. used for heated rods and steam generator U-tubes. In the

subdivision of volumes and slabs the position of instrumentation 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 SPES Nodalization Description

The Relap5/Mod3 nodalization for the SPES facility is shown in Fig. 5. The correspondence

between the zones of the facility and the nodes of the code model is presented in Tab.3. In this

table the facility is divided in zones, composed by various hydraulic elements. These components

are reported in the table according to flow paths in nominal condition,;. Number and type of the

hydraulic nodes are indicated in the table itself.

The utilized code resources for the SPES nodalization are summarized in Table 4. In

particular, the number of hydraulic components and of heat structure are reported.

Hereafter some significant aspects of the developed nodalization are summarized.

The vessel miodel consists of 45 hydraulic components which are connected through 48

junctions.

The heat structures used in the vessel model are made up of 78 heat slabs subdivided in:

0 24 active structures for the heaters exchanging heat with the pipe component 130 (composed

by 12 volumes), where the overall power is dissipated: two stacks of 12 slabs simulate the

three hot rods and the remaining 94 rods of the core bundle-,

- 4 internal non-active structures simulate the connection zones (in the lowver part and in the

upper part of the bundle) exchanging heat with the branch components 100-01, 110-01, 120-

01 and 140-0 1, where no power is assumed to be dissipated;

* 50 heat slabs simulate the vessel structures; in 19 over 50 slabs the heat exchange with the

environment is imposed;

24
In the vessel model all the bypass flow paths reported in the facility description have been

modeled:

*bypass from lower plenum to upper plenum simulated by the pipe components 1L12 and 114

connected through the single junction 113;

*bypass from downcomer top to upper head simulated by the pipe component 145 and the

single junction 155.

The three loops are almost equal in the nodalization (33 volumes, 32 junctions and 42 slabs)

and are differentiated for the pressurizer (placed in loop 2). For simplicity the loop 3 is not shown

in Fig. 5; it has the same features of the loop 1.

The steam generator U-tubes are modeled asymmetrically, assumiing that the largest portion

of the exchanged power between primary and secondary side occurs across the slabs of the rising

part of the package.

The pumps in the three loops are considered equal; different working conditions are achieved

by changing the shaft velocity. The related input two phase curve differences, which for

completeness have been considered in the nodalization, have been set equal to ones related to the

LOBIJ~od2 pumps.

Two additional systems can be noted in the pressurizer nodalization:

* a time dependent volume and related trip valve (component 60-01 and 65-01 respe.-tively);

* a time dependent junction and related time dependent volume (components 45-01 and 40-01

respectively).

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

constant in the 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.

Still, the black structures inside the pressurizer model represent the internal heaters; they

simulate in the code model also the external heaters installed in the facility.

The motor valve 75 and the related time dependent volume 70-01, connected to the top of

the pressurizer, simulate the PORY system, while the time dependent volume 80 2nd the time

dependent junction 8 5 simulate the leak detected in the pressurizer in a previous SPES. test.

The slabs with an asterisk represent the zones where the heat losses to envi-onment are

considered.

Accumulators and related surge lines (with valves) and LPIS simulator are connected with

the cold legs of the two intact loops.

The secondary side nodalization of the three steam generators are equal both concerning the

hardware of the facility and the control system (33 nodes, 34 junctions and 25 heid slabs): in

particular the volume identification number can be obtained by changing the first digit in the loop

1 related one (6 in place of 5 for loop 2 and 7 for loop 3). So only one'nodalization will be

described hereafter.

Five zones can be recognized in each steam generator:

1. the dowucomner, consisting of a single stack of nodes (the two external dowicomers are

gathered in a simple pipe component);

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

3. the top of the vessel, including the separator, the dryer and the steam done regions;

4. the steam line downstream the dome of each SG, simulated with the pipe component 525-01,

the motor valve 580 and time dependent volume 581. This last component is also utilized like a

pressure control volume imposing constant pressure in the volume itself,

5. the feedwater line connected to the top of the downcomer, simulated with the pipo component

565-01, time dependent junction 591 and the time dependent volume 590.

25
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 minimumn between the

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

The components 5 10-01 simulates the separator that is necessary in the code model in order

to achieve quality equal to one in the steam dome.

The pre-heaters are not simulated in the code model.

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

following functions are accomplished:

" feedwater injection and steam line previously described;

" EFW injection: simulated with the time dependent volume 592 and with the time dependent

junction 593 (used only in the steam generator of the loop 1);

* SRV safety system: simulated with the time dependent volume 585 (safety tank) and with the

motor valve 584 (safety valve);

* liquid level control system: realized through two time dependent volume components (596 and

594), each one connected with one time dependent junction (597 and 595 respectively). This

system assures constant value for steam generator downcomer liquid level during the steadyýstate period.

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. [13].

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. 5 (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. 5 (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 (SP-SB-04 in this case), involves at least one

among the following steps:

26
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 "Ky-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 firame, adopting

proper scaling criteria (time preventing, volumelpower scaling) a comparison can be made

between predicted and experimental data in the area of PWR and BWR. This mus7: be used to

detect nodalization and user choice inadequacies. Correction of errors or deficiencies leads to a

"3on 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 SPES

facility.

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

previously defined (reported in Tab. 5) have been verified; in particular, the compari:;on between

the calculated and the measured volume vs. height curve and the distribution 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

steps b) and c) described above: in the first case the International Standard Problem 22, refs. [14]

and [15], has been in considered, while in the second case the previous simulation with the version

Relap5fMod2, refs. [5] and [ 16], 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 RelapSIMod2 simulation of SP-SB-04. ref. [16], and it was not

repeated in a systematic way for the RelapSIMod3.2 simulation. No important differences related

to any of the finding of the Relap5fMod2 analyses are expected.

4. ANALYSIS OF POST TEST CALCULATION RESULTS

Results of code runs are discussed in this chapter. These include:

a) 100 s steady state;

b) reference calculation results;

c) results from sensitivity studies.

It may be noted that item a) constitutes the final part of the nodalization qualification process

described in the previous chapter. In addition, qualitative and quantitative accuracy evaluations

have been performed and are documented for the 'reference calculation', and only quantitative

accuracy is calculated for the 'sensitivity studies'.

When calculating the quantitative accuracy, twenty-three time trends have beerL selected in

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

measured quantities that flffly describe the experimental scenario. The related list is given in the

first column of Tabs. 10 and 12.

When calculating qualitative accuracy, including the comparison between lime trends,

reference is made to the same list (e.g. App.s 2 and 3) of Tab. 12 with the following chianges:

* quantities 04 and 03 in Tab. 12 are both reported in Fig. 3; so quantities from 0)5 to 23 are

shown in Figs. 4 to 22, respectively;

* the following quantities have been added to the comparison: pressure drop across DC-UN

bypass, pressure drop in the U-tubes ascending leg (also a measure of liquid hold-tip in the U-.

tubes), core inlet flowrate, pressure drop in cold leg, mass flowrate in SG downcoiner, hot leg

mass flowrate; these are reported in Figures from 23 to 28, respectively. 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. 6 and in App. 2. In both cases, resulting, values are

compared with experimental data. In the case of Tab. 6, for completeness, the data calculated by

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

It may be noted that the data in Tab. 6 deal with most of the parameters imposed for the

nodalization qualification process (Tab. 5): 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. 2, numbering of figures is

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

The analysis of data brings to the following conclusions:

- the criteria for nodalization qualification are fulfilled, though the complete compari:;on between

data in Tab. 6 and in App. 2 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. 6 (e.g. the prinmary circult power balance can be obtained by

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

seen by considering the errors in fluid temperatures owing to the fact thai the direct

experimental information about bypass flowrate is uncertain (measurement error not available);

- the calculated values are stable as it results from Figs. 1 to 26;

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

31
- discrepancies between measured and calculated values of heater rod temperatures, Figs. 8 to

10 in App. 2, come from the position of thermocouples and from generic experimental error

(the calculation result refer to the surface, the experimental data are taken slightly inside the

surface, the error almost disappears at low linear rod power, during the transient);

- the discrepancy in Fig. 14 (pressure drop across steam generator). -is attributed to the

experimental error and to the position of the measurement pressure taps not accounted for by

the calculated results;

- the last explanation is also valid in the cases of pressure drops in Figs. 16, 17, 19, 20 and 21;

the unknown position of pressure taps is specifically valid in the case of Fig. 20;

- the discrepancy in Fig. 23, related to the recirculation mass flowrate 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

Relap5/mod2. A 'blind' post test was performed by Relap5/mod3.2 constituting the reference

calculation for this study (label S4RO); the related time trends and significant single valued

parameters are reported, together with experimental data, in App. 3 and in Tab. 7, respectively.

The input deck of the reference calculation is reported in App. 5.

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. 3);

b) comparison related to the timing of the resulting events, Tab. 7;

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

CSNI. matrix, refs. [ 17] and [ 18], as given in Tab. 8;

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

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

in Tab. 9;

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

in refs. [7] and [19], see also App. 1, as given in Tab. 10.

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

variables and at the same time some RTA evidence are outlined considering the trend of related

parameters; the discussion about items c), d) and e) is given in sect. 4.2.1. An asterisk(*

identifies the items that are subject to sensitivity analyses.

Absolute Pressures

The primary system pressure is well predicted by the code (Fig. 8 below and Fig. 1 in App.

3): the phenomenological phases (e.g. subcooled blowdown, saturated blowdown and steam flow

from the break) can be easily recognized from the calculated time trend.

The steam generator pressure is slightiy underpredicted as shown in Fig. 2 of App. 3; reasons

for this appear connected with the overestimation of heat transfer between primary and secondary

sides and, eventually, with overestimation of heat losses from secondary side to the environment;

a role could be held in this connection, by minor discrepancies (undetected, so far) between

measured and calculated closure times of feedwater and steam lines valves.

32
The accumulator pressures are well predicted starting from the accumulator ir~jection time

that is very well predicted as shown also from the data in Tab. 7 (comparison between experiment

and S4RO results). The final pressure measured during the test for one of the accumulators is

lower than the calculated value, as results from Fig. 3 in App. 3. Reason for this cannot be

understood from the experimental data base; apparently, the isolation valve closed with some

delay.

Fluid temperatures

Measured and calculated fluid temperatures are compared in Figs. 4, 5, 6, and 11 of App. 3,

the last one related to the steam generator and the other ones related to the primary &-cuit.

Good agreement can be observed from Fig. 4 (core inlet fluid temperature) froim where the

start of saturated blowdown can be identified. The predicted core outlet fluid temperature

presents a superheating larger than in the experiment toward the end of the transient. 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 200 s

into the transient, i.e. following the emptying of the upper head.

The underprediction of the fluid temperature in the bottom of the steami generator

downcomer (Fig. 8 in App. 3) derives from the same reasons discussed for the pressure.

Mass flowrates

The measured values of break flowrate (Fig. 9 below and Figs. 7 and 9 in App. 3), the ECCS

flowrate (Fig. 10 below and Fig. 10 in App. 3), core inlet (Fig. 25 in App. 3), hot leg mass

flowrate (Fig. 28 in App. 3) and the steam generator downcomer flowrate (Fig. 27 in App. 3) are

compared with the respective calculated trends.

Break flowrate is overpredicted (*); however, the related error can be considered within the

uncertainty bands.

ECCS flowrates are clearly overpredicted; the reason for this seems connectiAd with the

experimental errors" *)

The error in core inlet flowrate appears a consequence of instrumentation inadequacy as also

results from observing the good agreement between measured and calculated trends; of hot leg

flowrates: the "inadequacy of instrumentation"' derives from the phenomenon of stream at core

inlet (saturation conditions, see also Fig. 4 in App. 3) that causes high volumetric flow not

corresponding to high mass flow. Oscillatio 'ns appear in the calculated trends (mostly one of the

loops) of hot leg flowrates, starting from about 400 s into the transient; these could bie explained

with the 'siphon condensation mechanism', described in ref. [20]: the siphon condeasation is a

natural circulation mode that appears in the primary side loop of a PWR when man;s inventory

value is about 70% of the initial mass. In this condition steam coming from the core, condenses in

the rising part of U-tubes; however due to COEL (counter current flow limitation) at U-tubes

inlet, the condensate does not drain back to the core, and liquid level formation ofcurs in the

ascending side of U-tubes (in this phase zero flow cold leg occurs). This situation i:; valid until

the liquid level reaches the top of the U-tubes, when the siphon effect occur, causes liquid

+ A data base for an experiment typically consists of several hundreds time trends (up to 2000s) and hunidreds of

point values or time functions for boundary and initial conditions, plus indications about status of vabes, pumps

and of various systems; the data base, as in the present case, is judged as qualified in a global sense, and it is

certainly suitable for code assessment purposes. However this does not imply that all the supplied vaht= are

unaffected by more or less large errors. Typical examples, in the present data base are constituted by the core mas

flowrate that is inconsistent with data for hot legs flowrate , and by accumulators integral mass flowrate that is

inconsistent with the supplied data for accumulators in~jected mass and primary system mass inventory.

draining to cold legs ant to the care. The cycle may repeat several time in a real siphon. Liquid

accumulation may be due either to condensation or de-entrainmtent of droplets carried by the two

phases mixture.

Following the steady state misprediction (already discussed), steam generator downcomer

flowrates (experimental and calculated values) substantially agree and achieve a value close to

zero.

Residual Mass

A good agreement between measured and calculated trends can be observed from Fig. 14 of

App. 3; this is at the origin of the conclusions previously drawn, connected with reliability of EGG

related instrumentation.

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. 3. 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).

The transient comparison is acceptable in relation to all the considered trends also having in

mind the above limit. Deep studies of local phenomena could be carried out, starting from those

trends, to improve the comparison leading to a 'tuned input deck'. This has not been among the

purposes of the present activity.

Levels

The pressurizer level (Fig. 11 below and Fig. 21 in App. 3) is very well predicted in the

calculation, testifyring of the good prediction of the subcooled blowdown flowrate.

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

are directly connected with the occurrence of core dryout. The experimental trend (e.g. Fig. 12) is

characterized by a lower peak at the transient beginning, when a short duration dryout is also

observed; the related PCT (Peak Cladding Temperature) is only 15 K higher than the saturation

temperature. A wider core level depression occurs starting from about 1400 s into the transient

leading to the final dryout, quenched by LPIS injection. The trend of this variable is strongly

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

threshold phenomena like loop seal clearing.

Core level seems badly predicted (Fig. 12 below and Fig. 15 in App. 3); however, the calculated

curve qualitatively reflects the experimental one (*). Reasons for quantitative discrepancies in this

case, are connected with the method used to derive the level in the experiment (in other words the

definition of experimental collapsed level is different from the quantity calculated by the code) and

with the distribution of pressure drops in the entire loop that are not fiflly 'tuned&, as remarked

before. Additional reasons are frequently introduced in the literature to explain such discrepancies

involving the poor prediction of interfacial drag in the core and the CCFL phenomena in various

parts of the loop: clearly these roots of error cannot be excluded here.

Rod Surface Temperatures

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

core must be considered as describe into detail in ref. [8].

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. 3, and Fig. 13 below related to the top region).

Predicted rod surface temperature trends follow qualitatively and quantitatively well the

measured values. The first drycut appearing in the middle core region (Fig. 12 in App. 3), only 15

K overheating, is not predicted by the calculation. The last dryout situation is very well predicted

by the calculation both in terms of timing and of PCT (Figs. 12 and 13 in App. 3); this dryout

does not appear in the bottom core region neither in the experiment nor in the calculated results.

Evidence of some RTA based on specific parameters trends

Clearly the parameters trends described above are not independent upon each other. Some

interactions, identifiable both in the experimental and in the calculate data base, are mentioned

hereafter:

" the end of subcooled blowdown can be clearly seen by the decreasing of the rate of

change of the primary side pressure and of the break integral mass flowrate (Figs. 8 and

9);

a the first core level depression at about 100 s. into the transient (Fig. 12) brings the system

to condition close to the core dryout as it can be seen in Fig. 12 in App. 3; suitable core

cooling condition are reestablished after loop seal clearing;

" the second core level depression at about 400 s. into the transient (Fig. 12) is the

consequence of primary mass inventory depletion ( Fig. 14 in App. 3); accumulators

intervention causes the establishment of adequate core cooling conditions;

" the third core level depression at about 1500 s. into the transient (Fig. 12) causes

extended core dryout (Fig. 13) that is quenched by LPIS actuation (Fig. 10);

" the emptying of pressurizer (Fig. 11) occurs in the period during a deep negative gradient

of primary side pressure;

" steam generator secondary side acts as a heat sink only in the first period of the transient;

afterward essentially it acts as a heat source for the primary side fluid as can be seen in

Fig.29 in App. 3. However, the thermal power exchanged across the U-tubes is limited by

the low value of mass flow rates (Fig. 28).

4.2.1 Qualitative and quantitative accuracy evaluation

Qualitative accuracy

A part of the qualitative accuracy evaluation has already been completed, consisting of the

consideration in sect. 4.2, leading to three starred items that are at the basis of the design of

sensitivity calculations.

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

consisting in the identification of phenomena (CSN[ Eist) and of RTA. In both cases five levels of

judgement are introduced (E, R, M, U, and -) whose meaning is detailed in the notes of Tab. 8

and in App. 1. The related results are reported in Tabs. 8 and 9, where for completeness the

information related to Relap5/mod2 results, are given.

A positive overall qualitative judgement is achieved if t

U 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 tLT mark is present;

b) all RTA of the experiment are present in the calculated data base with the exception of the one

dealing with the first dryout; in this case, the following considerations apply:

- very small values characterize the related PCT and duration;

40
- the Aspect occurs only at one care elevation and at that core elevation it does no,,: occur in all

positions;

- the occurrence of the RTA has not any consequence on the remaining part of the test; in

other terms it does not trigger any event or system scenario bifurcation.

As a consequence of the above this RTA has no role in the evaluation of code calculation

performance;

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 E~t University

of Pisa, and widely used has been adopted.

The methodology is based upon the use of the Fast Fourier Transform (e.g. riXf [18]); its

main features are detailed in App. 1.

The results of the application of the method are given in Tab. 10, where again the information

related to Relap5/rnod2 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 = 0.24 compared with the acceptability limit of 0.4) and the prinary system

pressure accuracy (AA = 0.055 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.

Design of sensitivit calculation

Following the performed qualitative and quantitative accuracy evaluation there i,, no need to

perform additional calculations.

Therefore, the planned sensitivity analyses are carried out with the main purpose of

understanding the code behavior (including the robustness of the present solution) rather than

following needs from accuracy evaluation. Nevertheless, emphasis is given to the findings of sect.

4.2 and the following objectives for the analyses are established, aiming at addressing the starred

()items in sect. 4.2:

1) prediction of break flowrate;

2) prediction of ECCS flowrate with main emphasis to the accumulator delivered mass;

3) prediction of the core level.

Tab. 10 : Summary of results obtained by application of FFT method to the selected

parameters for the reference calculation

44
4.3 Sensitivity calculations

Considering the reference calculation, a series of sensitivity analyses have been carried out,

addressing the items 1) to 3), reported in section 4.2.1 and additional input parameters; these are

essentially user's choices that may have some effect in solving discrepancies leading to the same

three items.

The characteristics of the performed calculations can be drawn from Tab. 11, together with

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

summary of the EFT results related to all the parameters for all the performed sensitivity

calculations are given in Tab. 12.

One of the sensitivity calculation (R5 in Tab. 11) requested the renoding of the steam

generator. The new noding is given in Fig. 14.

The comparison between calculated and measured trends for each sensitivity analysis is

reported hereafter and in Appendix 4 related to eight time trends (subensamble of the list of 23

time trends of Tab. 10).

a) Break flow rate

In order to obtain a better prediction of the break mass flow rate, two parameters have been

tuned. In the first case (run RI), the discharge coefficient at the break junction has been decreased

and set to 0.7: in the first 200 seconds of the transient the flow rate (see Fig. 15) is well predicted,

after that the trend is overestimated, although the discrepancy with the experimental data is

smaller than in the reference case (about one halft). The improvement in the break flow rate

prediction corresponds to a worst prediction of the primary pressure trend (see Fig. I E) and of the

occurrence of the final dry out that is delayed. From a quantitative point of view, the global

accuracy has a worst value.

In the second case (run R6), the value of the form loss coefficient (reverse) for -the cold leg

has been increased: there is a very little improvement of the break flow rate and the pressure is

still well predicted (Figs. 17 and 18). The global result obtained with the FFT applicuttion can be

explained with a better prediction of the loop seal behavior.

b) ECCS mass flow rate

Several calculations have been performed, aiming at the improvement of the acumulators

mass flow rates and are documented in Figs. 19 to 24.

The run R2 is characterized by the delaying of the injection stop of one accumulator respect

to the other (see Fig. 19): this did not affect so much the overall transient (the A~ value is the

same of the reference calculation), but the dryout is delayed (Fig. 20) at the high levels in the

core, whereas in the other levels (see Tab. 11) the rod temperature is better predicted.

The reduction of the accumulators mass flow rate through the decrease of their discharge

area is documented in Figs. 21 and 22, where the results from runs R3/1, R3/2 anid R3/3 are

reported. In the first two cases the in~jected mass is the same, but the discharge area is; reduced to

the 12 % and 6 %, respectively: the slope of the ECCS flow rate curve is better predicted up to

about 600 s, after that the trend becomes similar to that of the reference case. &i a result, a

temperature excursion (more evident in the case R3/2) is predicted after the actuation of the

accumulators, and the final dryout is delayed. The run R3/3 is characterized by the reduction of

the discharge area and a reduction of the injected mass: in this case, other than the waly dryout

due to the lower injection rate, an early (about 450 s) dryout is calculated with the anticipated

intervention of the LPIS. This fact reflects on the global accuracy evaluation so that the R3/3

results the worst calculation.

45
The combination of runs RI and R32 (the simultaneous reduction of the accumulators

discharge area and the break discharge coefficient) did not influence very much the accuracy of

the calculation (Figs. 23 and 24).

c) Core level

Aiming at the improvement of the core level the following analyses have been performed:

- increase of the number of nodes in the ascending side of U-tubes (run R5), in order to improve

the primary to secondary side heat exchange (the modified nodalization is shown in Fig. 14):

the effect on the prediction of the core level and the rod temperature is small (Figs. 25 and 26),

but the accuracy of the overall calculation is slightly improved (fluid temperatures and loop

seal behavior are better predicted);

- the same considerations are valid for the run R9 (Figs. 27 and 28). In this case the increase of

the heat exchange is obtained setting the recirculation length (to improve local heat transfer

coefficient) equal to 0.05 in the secondary side of the SGs;

- reduction of the form loss coefficients (reverse) in the core by-pass (run R7): small effect on

the core level prediction and delay in the dry out occurrence (Figs. 29 and 30), with a small

improvement of the overall accuracy;

- activation of the CCFL option at the inlet of hot leg, core outlet and U-tube inlet (run R8):

with respect to the previous case, the effect on the addressed parameter is again negligible

(Fig. 3 1) but the time of dryout is better predicted (Fig. 32) and the overall calculation

accuracy is the same, as in the reference case;

- the activation of the level tracking option in the core and upper plenum (run RA) strongly

influences the core level prediction (Fig. 33): the calculated and measured trends are in

agreement in the period 550 - 900 s, but in the initial and final part of the transient, the

calculated level presents large discrepancies related to the experimental data, leading to a

dryout at about 200 s (Fig. 34) and to the anticipation of the final dxyout (about 400 s). As a

result, the overall calculation accuracy results very bad. This new capability of the

Relap5IMod3.2 requires specific effort to be qualified. These have not been conducted in the

present fr-amework

5. CONCLUSIONS

The analyzed transient (SP-SB-04) is a small break LOCA experiment originated by a rupture

in the cold leg in one of the three loops of the SPES facility. No high injection system is provided

during the test; accumulators intervention prevents unacceptable core rod temperature excursion

up to about 12001 s; two dtryout situations occur: the first one, at about 130 s into the transient

leading to a temperature excursion less then 15 K. is quenched by an intrinsic mechanism lice loop

seal clearing about 10 s after PCT is reached; the second one is quenched by the interven~tion of

the low pressure injection system.

A qualified Relap.5fMod3.2 nodalization has been used for the analysis. The com ':arison

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, except for the first dryout occurrence.

Three main discrepancies have been identified, relating to the mass flow rate from the break,

the ECCS delivered mass and the core level. Several sensitivity calculations have been perf .rmed,

addressing these specific aspects.

The following considerations can be pointed out:

1) the variation of parameters considered in the sensitivity calculations, does not afficct the

phenomena but only the sequence of events;

2) the comparison between experimental and calculated trends shows a-good agreement; the

adjustments (tuning) of the flowrate delivered by ECCS and, in particular, of the

accumulators behavior toward the experimental data, causes a disagreement in the core heat

transfer and the worsening of the overall transient prediction;

3) a tuning (if the break flow rate is needed: the tuning of about 20 % during all the transient

seems to be adequate; this means changing in a reproducible (related to all other small break

LOCA analyzed) way the break discharge coefficients of the Relap5 input deck in the range

08- 1.2 (obviously keeping each coefficient constant during the transient):

4) the mixture level tracking option (the digit "I" in the code input deck) has been introduced in

the run RA to improve the core level prediction, but it needs the tuning of other parameters

(not performed in the present frame-work), otherwise its results are inconsistent with the

other nodalization choices:

5) a small effect of the CCFL parameter, the convection length, the by-pass flow path

resistance, the K reverse in the cold leg andi the number of nodes has been noted.

The reference calculation can be used for uncertainty evaluation, ref. f 6]. and specifically,

for the development oif Code having the capability oif Internal Assessment oif Uncertainty (CIAU),

Qualitative and quantitative accuracy evaluation

QUALITATIVE AND QUANTITATIVE ACCURACY EVALUATION

A complete code assessment activity involves a large effort at different levels. Some ideas

about various steps that are part of the code assessment process will be given in thl. following,

with particular attention to the independent assessment phase activities (performed by code

users) following the developmental ones.

A comprehensive comparison between measured and calculated trends or values should

include the following steps:

a) comparison between experimental and calculated time trends;

b) comparison between values of quantities characterizing the sequence of resulting events;

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

CSNI matrix, ref. [17];

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

Aspects (RTA, also used for code uncertainty derivation, e.g. ref. [6]);

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

The considered steps as mentioned above, are part of a wide range code calculating

assessment process, where relevant findings from International Community and from previous

experiences of the here involved research groups are exploited. An important role is taken, in

this contest, by the recently issued OECD/CSNI reports, refs. [17] and [18], both in the area of

experimental data qualification and code assessment.

A very high number of selected variables or time trends are recorded during c~xperiments

in ITF, typically up to 1000, item a); a much lower number is recorded in each experiment

available from ITF, around 100. More than 20 time trends are assumed to realistically

characterize an experiment and must be used in the present frame: expertise is needed in the

selection that, however, can be made standard having as reference the different types of

transient (e.g. identified in ref. [18]). The code user must derive an overall evaluation of

calculation performance avoiding a final judgment that should be derived from th-.~ following

steps: it must be checked that calculation results are qualitatively correct (e.g. a valley or a

positive slope for a reasonable time period in any experimental trend should not correspond to

a peak or to a negative slope, respectively, in the calculated trend); errors must be tolerated.

Qualitative accuracy evaluation are involved under steps b) to d), that can be completed

having in mind the results form step a). Sequence of events must be identified havng in mind

the experimental data base; actuation or trips of Engineered Safety Features (valves, pumps,

scram, ECCS) and dryout/rewet occurrences are part of the "resulting sequence of c~ventsP.

The list of phenomena classified by CSNI, item 3), concerns with transient types (e.g.

Large Break LOCA, Small Break LOCA, etc.): this is used to check the suitabilit 'y of ITF in

simulating that phenomenon, whether that phenomenon is part of the data base and to judge

the simulation capabilities of the calculation. Five levels of "subjective" judgments are used as

detailed in the -next section. It may be noted that the first two sub-steps are :part of the

qualification of the experimental data base.

Basically the activity under item 4) is the same as before, the only difference being that

phenomena are substituted by RTA (Relevant Thermalhydraulic Aspects). RTA characterize a

single transient (e.g. a 6 % Small Break LOCA without igh Pressure Injecton System) and

not a class of transients. The same levels of judgment are adopted. A qualitatively acceptable

calculation implies that all RTA are evident in the experimental and calculated dama base and

that no U mark is present (see below). RTA are characterized by values identified as SVP

(Single Valued Parameters), NDP (Non Dimensional Parameters), IPA (Integral PArameters)

69
and TSE (parameters belonging to the Time Sequence of Events): more -than forty of such

values must be used for a complex transient.

The FFTBM, item e), allows a quantitative judgment for a given calculation. Each set of

two curves constituted by a calculated and a measured time trend can be processed by

FFTBM. The transformation from time to the frequency domain avoids the dependence of the

error from the transient duration. Weight factors are attributed to each time trend to make

possi'ble the summing up of the error and the achievement of a unique threshold for accepting a

calculation. Quantitative accuracy evaluation must be carried out following demonstration that

the calculation is qualitatively acceptable. The same time trends selected at item a) above are

utilized as input to the FFTBM.

A2.1 Qualitative assessment.

The procedure for the evaluation of the qualitative accuracy includes the following steps:

1 use of the phenomena specified in the CSN[ validation matrix that are valid for any kind

of transient;

2 subdivision of the considered transient into "phenomenological windows" (i.e. time

spans in which a unique relevant physical process mostly occurs, and a limited set of

parameters controls the scenario): phenomena consequent to the physical processes

characterize each phenomenological windows;

3 for each "phenomenological window":

3.1 identification of the "relevant thermalhydraulic aspects". These are the events or

phenomena consequent to the physical process and are peculiar to each

transient;

3.2 selection of the parameters characterizing the "relevant thermalhydraulic,

aspects";

4 qualitative analysis of obtained results by evaluating and ranking the comparison

between measured and calculated trends.

The qualitative analysis is based on five subjective judgment marks, that are applied both

to the matrix of phenomena and to the list of relevant therrnalhydraulic aspects: it essentially

derives from a visual observation of the experimental and the predicted trends:

a) the code predicts qualitatively and quantitatively the parameter (Excellent - the calculation

falls within experimental data uncertainty band);

b) the code predicts qualitatively, but not quantitatively the parameter (Reasonable - the

calculation shows only correct behavior and trends);

c) the code does not predict the parameter, but the reason is understood and predictable

ftM- the calculation does not lie -within experimental data uncertainty band and at

times does not have correct trends);

d) the code does not predict the parameter and the reason is not understood (U~nqualified -

calculations does not show correct trend and behavior, reasons are unknown and

unpredictable);

e) Not applicable ()

Through this analysis we can operate a first classification about the calculation quality.

The qualitative step is a necessary prerequisite to the application of the quantitative

analysis: it is meaningless performing this last one, if a calculation is not qualitatively correct.

A2.2 FET based method description

A fundamental property of the Fourier Transform consists in the capability to analyze any

relationship between two quantities in the time domain in a different domain witixout lack of

information with respect to the original one. When using functions sampled in digital form, the

FFT can be used, i.e. algorithm that computes more rapidly the discrete Fourier Transform.

To apply this algorithm, functions must be identified by a number of values which is a

power of 2. Thus, if the number of points defining the function in the time domain is N=2m+l,

the FFT gives the frequencies fn = n/T, (n = 0, 1,...,2m~), in which T is the time duration of the

sampled signal.

The accuracy quantification of a code calculation considers the amplitude, in th-. frequency

domain, of the experimental signal F,~,(t) and the error function

A F = Fcac(t) - Fexq, (t).

In particular, the method characterizes each calculation through two values:

" a dimensionless average amplitude

A.A =-n~

n=O

" a weighted frequency

ZjZF(n)j- f.

VIF --0i

n=O

The most significant information is given by AA, which represents the relative magnitude

of the discrepancy deriving from the comparison between the addressed calculation and the

corresponding experimental trend (AA = 1 means a calculation affected by a 100 % error).

The WF factor characterizes the kind of error, because its value emphasizes if the error

has more relevance at low or high frequencies, and depending on transient, high frequency

errors can be more acceptable than low frequency ones; in other words, analyzing

thermaihydraulic transient, better accuracy is generally represented by low AA values at high

NWF values [18].

Trying to give an overall picture of the accuracy of a given calculation, average indexes of

performance are obtained by defining:

(AA)tot = Z(AA) -.(wf)i

i=1

71
("F)tot = W)-(W4)

with

Nvar

i=1

where Nvar is the number of the analyzed parameters and (Wf)j are weighting factors

introduced to take into account the diferent importance of each parameter from the viewpoint

of safety analyses. Briefly, each (wf)i takes into account [19]:

* xerimental accuracy: experimental trends of thermalhydraulic parameters are

characterized by a more or less sensible uncertainty due to:

- intrinsic characteristic of instruments

- method of measure

- different evaluation ways necessary to compare experimental measures and the code

calculated results

* saetyrelevance: particular importance is given to the accuracy evaluation of code

calculations concerned with those parameters (such as pressure, peak clad temperature,

etc.) which are relevant for safety and design.

Further contribution is given by a factor which normalizes the AA value calculated for the

selected parameters with respects to the AA value calculated for the primary pressure. This

factor has been introduced in order to consider the physic relations existing between different

quantities (i.e. fluid temperature and pressure in case of saturated blowdown must be

characterized by the same order of error).

So doing the weighting factor of the j-th parameter is defined as:

(wf) - (wcxp (WP~ )j.(w -j(W-4m

I (W-4p -(wsr) j -(Wna4j

j=1

where:

" wexp is the contribution related to the experimental accuracy;

" wsafis the contribution which expresses the safety relevance of the addressed parameter,

* wnorm is the component of normalization with reference to the average amplitude

evaluated for the primary side pressure.

This introduces a degree of engineering judgment that has been fixed by a proper and

unique definition of the weighting factors.

A2.3 Quantitative assessment.

This further level can be managed by means of the application of the FFTBM.

The most suitable factor for the definition of an acceptability criterion is the average

amplitude AAX With reference to the accuracy of a given calculation, we can define the

followinig acceptability criterion:

72
(AA)tot -<K

where K is an acceptability factor valid for the whole transient. As lower is the (Ajk)tot value,

as better is the accuracy of the analyzed calculation (i.e. the code prediction capability and

acceptability is higher). On the other hand, (AA)tot should not exceed the unit in any part of

the transient (AA = 1 means a calculation affected by a 100% error). Due to this rxjuirement,

the accuracy evaluation should be performed at different steps during the transient, to verify if

this condition is not satisfied in any phase of it.

With reference to the experience gathered from previous application of this methodology,

K = 0.4 has been chosen as reference threshold value identifying good accuracy of a code

calculation. In fact, taking into account the previous applications, it has been noted that results

in the range:

I1. (AA)tot5 •0.3 characterize very good code predictions;

2. 0.3 < (AA)tot! •0.5 characterize good code predictions;

31 0.5 < (AAhtot! •0.7 characterize poor code predictions;

4- (AAhtot > 0.7 characterize very poor code predictions

A similar criterion can be used to evaluate the code capability in the single parameter

prediction; clearly, in this case the AA factor is the one evaluated for the addressed parameter.

Recent activities have been aimed at defining upper acceptability Eimits to the AA values

related to safety relevant parameters, like cladding temperature, primary pressure, primary

residual mass. As an example, a fiirther requirement to be fulfilled is related to the AA

evaluated for the primary side pressure. The accuracy in the prediction of this basic

thermathydraulic parameter, in the various phases of the transient, should satisfy the following

criterion:

AAv, < 0. 1

10. SUPPL.EMENTARY NOTES

11. ABSTRACT r" wads cr Ams)

The present document deals with the RELAM5MOD3.2 analysis of the small break LOCA experiment SP-SB-04 performed in

SPES facility. SIDES is a PWR simulator (Integral Test Facility) installed at SIET center in Piacenza (IT). Volume scaling and core

power scaling factors are 1/427, with respect to the Westinghouse 900 MWe standard reactor. The experiment is originated by a

small break in the cold leg (Z' equivalent break area in the plant) without the actuation of the high pressure injection system. The

test starts from full power and is the counterpart of the test SP-SB-03, that started at an initial power roughly equal to 10% of

nominal power. Low pressure injection system actuation occurs after core dry-out The RELAP5 code has been extensively used

at University of Pisa; the nodallzton of SIDES facility has been qualified through the application of the version RELkP5/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.
