3. TEST OBJECTIVES i

The objectives of the PANDA integral systems tests are to provide additional data to: (a) provide a sufficient database to confirm the capability of TRACG to predict SBWR containment system performance, including potential systems interaction effects. (Integral Systems Tests) and (b) Demonstrate startup and long-term operation of a passive containment cooling system.

(Concept Demonstration).

The specific objectives ar sproach for test M6/8 covered by this test plan are:

a) Perform a test with nominal post-LOCA initial conditions

• with the IC initially operating in l

_ parallel with the three PCC condensers. This test will provide data showing the interaction between the PCC condensers and the IC, as well as the effect of the additional heat removal l

by the IC on containment and reactor system performance (M6).

i b) Study the effect of drywell-to-wetwell bypass leakage on containment performance,the bypass leakage area will be set at ten times the allowable SBWR value as scaled to l

PANDA (M8).

f The objectives discussed above have been combined into sequential stages in a single test plan.

o I

P i

e

'" Nominal post-LOCA initial conditions" are those used for test M3 which are derived from the SBWR main steam line break LOCA analysis at one hour after LOCA initiation.

- 4. TEST FACILITY CONFIGURATION The PANDA test facility is described in detailin Secdon 3 of PSI report ALPHA 410. For Tests M6/8 the PANDA facility will be configured to simulate the SBWR post-LOCA configuration as follows:

1) Table'4.1 identifies the key PANDA facility geomeuy and effective flow area ( A / d) characteristics. In Tabl-4.1, the required tolerance for the PANDA as-built value relative to

.the corresponding SB\\,R scaled.value is tabulated for each of these key characteristics. In addition, the required accuracy for the as-built value for each of the key characteristics is tabulated in Table 4.1. The actual as-built accuracy should be approximately equal to or less than the required accuracy tabulated in Table 4.1. The actual as-built accuracies depend on the source of the as-built value. These sources can be measurements by PSI or Electonvatt (i.e.

line losses, line lengths, elevations), manufacturer's specificadons or design standards (i.e.,

PCC/IC tubes), or calculadons from as-built dimensions (i.e., vessel volumes, losses for lines without flow tests).

2) The RPV will supply steam to the each dgwell with two steam lines (one to each drywell).

These two steam lines will have the same pressure loss characteristics.

3) RPV heater power will be controlled as a function of time to simulate the scaled decay heat i

and stored energy.

l

4) The IC unit will be lined up to operate in parallel with the PCC condensers. The IC feed &

drain will be open with the IC vent line closed initially. The IC vent may be opened in a later i

pardon of the test if the IC accumulates enough non-condensable gas to force the IC to shutdown on its own. If the IC vent is opened for :he later portion of the test it will remain open. The IC vent line is not scaled consistently with the 1:25 scaling of PANDA to SBWR.

t

5) All three PCC units will be lined-up to take feedflow from the drywells, to vent noncondensables and steam into the water volume of the suppression pool, and drain condensate to the GDCS volume.

6) The PCC pools and IC pool will be filled and isolated from each other. During the test, no water will be added or drained.

25A5788 sH No.6 i

7) The only direct lines of communication between the drywell and wetwell will be as follows:

l

. a) through the vacuum breakers (when the wetwell pressure exceeds dgwell pressure sufficiently to open the vacuum breaker) and b) through main vent lines (which will be submerged within the wetwells), and c) through the bypass leakage path between the wetwell and drywell placed in service at 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> after initiation of the test and

. con gured to provide an effective flow area ( A /8) of approximately 0.40 cm:.

fi

8) The GDCS pressure equalization lines to both drywells will be open.

< 9) The GDCS drain line with check valve will be up to return PCC condensate to the RPV.

10) The Equalizing lines between the RPV and wetwells will be valved out of service.

' CONTROL SYSTEM DESCRIPTION -

In order to perform the transient integral system tests, several control systems are to be used to establish initial and boundary conditions for each test. These control systems will be used to manage and regulate the key test parameters prior to the test. Following test initiation, only the RPV heater power and the vacuum breaker controllers will be used. A main control system, which includes 'the electronic controllers, will be used to perform the operations.

5.1 RPV Heater Power Control The electrical power to the heaters in the RPV will be controlled automatically following test initiation, to match the decay power and RPV structural heat release specified in Section 9.

5.2 Drywell/Wetwell Vacuum Breaker Control The operation of the vacuum breaker valve will be controlied based on the measured pressure difference between the dnwell and wetwell. Drywell pressure is initially established at a value equal to or greater than the wetwell pressure to conform to the post-LOCA condition specified for the beginning of each individual test. During the course of a test if the drywell to wetwell pressure drops below a minimum value the vacuum breaker valve control will automatically open the valve. The wetwell-to-drywell differential pressure at which the vacuum breaker for Drywell 1 opens will be set at 0.47 psi (3.24 kPa), and the differential pressure at which the vacuum breaker for Drywell I closes will be set at 0.3 psi (2.06 kPa). The opening and closing differential pressure for the vacuum breakerin Drywell 2 will be set 0.1 psi higher than the corresponding setpoints for the Drywell 1 vacuum breaker, i.e., at 0.57 psi (3.9 kPa) and 0.4 psi (2.8 kPa), respectively.

REOUIRED MEASUREMENTS.

Table 6.1 gives ' he measurements required to meet the objectives for Tests M6/8. With the -

t exception of the temperature indication, no PANDA instrumentation other than that in Table 6.1 lis necessary for the performance ofTests M6/8. The sensors identined in Table 6.1 must be operable prior to initiation of these tests. It is acceptab!c if a sensor is not operable,if the backup identined in the second column is operable.

Temperature measurements in the PCCs and the various connected vessels are desirable, but not all of these temperature measurements are required for the performance of these tests as discussed below. The temperature measurements required for these tests.with an accuracy of 1.5 C are as follows:

RPV steam dome (at least one).

PCC/IC tubes; (It is required that 50% of the tube wall and fluid sensors be avail'able. The available sensors must include at least 40% of the probes above and at least 40% of the probes below the hori7.ontal mid-plane of the tube bundle. Within these constraints, the test engineer has responsibility and authority tojudge whether or not suf6cient PCC temperature sensors are operabic to initiate a test).

PCC/IC pools: 30% of the liquid probes including one of the lowest three elevations.

DW: 50% of the fluid probes including either the lowest elevation or one thermocouple from the water-surface probe.

WW: 50% of the gas probes,50% of the liquid probes and two out of three of the Doating j

probes.

GDCS pool: 50% of the fluid probes and one thermocouple from the Doating probe.

Vessel walls: 20% of GDCS, DW, and WW.

System lines: 50% of the gas and liquid temperature probes in each system line used for the test (if number of sensors is odd, round to lower whole number,i.e. 3 sensors total in one line means one is required).

{

In Table 6.1 a subset of the required instruments are identined as " top priority measurements".

Time history plots of these top priority measurements are to be included in the Test File (see i

Section 7.3) and the Apparent Test Results (ATR) Report (see Section 10). In addition to the top priority measurements identined in Table 6.1, there are other top priority measurements. These t

are: 1) the total electrical power to the heaters in the RPV which is detcrmined during post-test I

I i

data processing, and 2) some temperature measurements. The top priority temperature j

measurements are: RPV steam dome temperature measurement, highest and lowest temperature measurement location in each drywell, highest and lowest temperature measurement location in the gas space of each wetwell, highest liquid temperature measurement location in each wetwell, and one temperature measurementin the GDCS drain line and in each of the three PCC vent lines.

As noted in Section 7.4, the operator will perform checks as possible to confirm instrumentation performance. These checks will include comparison of redundant measurements.

DATA RECORDING. PROCESSING AND ANALYSIS 7,1 Data Recording During (approximately) the first two hours of the test (until the first drywell pressure peak is I

. reached) the data for all channels will be recorded at 6 samples per minute. During the rest of the test (after the peak drywell pressure is reached) the data will be recorded at I sample per minute. It is necessary that the data sampling rate be sufficient to record opening and closing of the vacuum breakers between the drywells and wetwells.

7.2. Data Records.

i The digitally acquired data will be recorded in real time for the entire duration of the test.

Immediately after the test, a copy of the data file will b~e created in order to have a backup record of the data file. Also to be recorded with this data file are allinformation required to perform subsequent processing of the data.

- 7.3 Data Sheets The following data sheets will be prepared for each test for inclusion in the PANDA Test File (PTF). The unique test number will be printed on each sheet.

1) print table containing the list of the measurements with their main characteristics

{

(identification, span, calibration constants, associated error, location on the facility, measurement channel number and sampling frequency)

2) graphs of top priority measurements identified in Section 6 as a function of time (time histories). Graphs may show groups of up to 8 test measurements.

3) print table showing the position (status) of all oneff valves,just after the beginning andjust before the end of the test and periodically throughout the duration of the test.

7.4 Data Processing and Analysis During the preconditioning of the test facility and during the running of the transient tests,the operators will monitor the required instrumentation identified for these tests in Table 6.1. The operators will check whether or not redundant measurements are consistent and perform other congruency checks' including zero checks as possible to verify that the instrumentation and data acquisition system r re working correctly.

Following completion of the tests described in Section 9, data reduction will be performed to

. support preparaticn of the Apparent Test Results Reports (ATR).This data reduction will include a representative set of time history plots of system flows, differential pressure, vessel pressurcs, air 1

TEST DESCRIPTION d

9.1 TEST DESCRIPTION.

A series of transient integral. tests will be conducted using the PANDA facility configured as described in Section 4. The tests will be performed using detailed procedure (s). The following summarizes the approach to be followed by the test procedure for Test M6/8.

4 The drywells, wetwells, GDCS tank and PCC/IC pools will be pre-conditioned and brought separately to their required initial conditions (or slightly higher temperatures and/or pressures if y

. heat loss or stabilization is expected to bring conditions within their required range).

2 The IC will be pre-conditioned to allow operation with non-condensable gas inventory as low as practical at the initiation of the test.The pre-test line-up should be with the feed, drain and vent line valves closed.

Once the initial conditions of the various vessels are confirmed to match the values specified in Table 9.1, the test is initiated as follows:

1 Start to open all valves which must be open in lines between vessels per the test configuration in Section 4, except the valves in the RPV to drywell steamlines and the IC feed and drain line, within a period of approximately 5 minutes.

Then, the following sequence should be performed as quickly as possible:

1) Open the valves in both RPV to drywell steamlines

2) Place RPV heater controls in automatic operation to follow the time dependent heater power determined from the specification in Table 9.2.

f

3) Open the IC feed, and after IC pressure has stabilized open the drain line valve.

4) In order to minimize the non-condensable gas concentration in the IC near the start of the test, open the IC lower vent within the first 5 minutes after the IC operation has been initiated. Close the IC lower after venting for approximately 5 minutes.

5) At 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> after test start, establish the bypass leakage path between the Wctwell I and Drywell 1 volumes.

REPORTS

.One brief Apparent Test Results'(ATR) report will be prepared covering the results for each of the transient integral tests based on _the data reduction described in Section 7. The ATR will summarize the apparent results. The format for this report will include: test number, test objective, test date, data recording period, names of data files, list of failed or unavailable instruments considered to be required for the test, list of pressure and differential pressure -

instruments with zero not in tolerance or over-range during test, deviations from test procedure, problems, table of actual initial conditions based on average and standard deviation over a one minute time periodjust before the start of the test of all parameters with a specified acceptance criteria in section 9.1 and time history plots of top priority measurements over the test duration.

l The ATR report is a verified report, approved by the PSI PANDA Project Manager, and will be i

transmitted to the GE within approximately two weeks of the completion of each transient integral system test.'

The Data Transmittal Report (DTR) containing all data for transient integral system tests M6/8, will be issued approximately two months after the last test is performed. It will provide detailed t

information on the test facility configuration, test instrumentation, test conditions and the format for the data. In addition, samples of data will be presented in tables and plots. The DTR will be

. verified before it is issued, approved by the PSI PANDA Project Manager, and then be transmitted to GE.
