3. TEST OBJECTIVES The obje :tives of the PANDA integal systems tests are to provide additional data to: (a) provide a sufficient database to confirm the capability of TRACC to predict SBWR containment system performance, including potential systems interaction effects. (IntegmlSystems Tests)and (b) Demonstrate startup and long-term operation of a passive conminment cooling system.

(Concept Demonstmtion).

The specific objectives and approach for the tests covered by this test plan are:

a) Perform Test M2 with nominal post-LOCA initial condi'. ions \\ith all steam flow directed through the steam line from the RPV to Dnwell 2 to create asymmetric distributions of steam and non<ondensable gas concentrations and demonstrate the PCCS/ containment performance under these conditions. Contingency testing is to be performed at the end of the 20 hour2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> performance of M2 to demonstrate PCC restart in response to increased heat load demand.

b) Perform Test M10A with nominal post-LOCA initial conditions' with only the two PCC condensers connected to Drywell 2 operational and all steam flow directed through the steam line from the RPV to Dgwell 2 to create asymmetric distributions of steam and non-

. condensable gas concentrations and demonstrate the PCCS/ containment performance under these conditions, i.e. long term migration of non-condensible gas (air) from Drywell 1 to Dgwell 2.

c) Perform Test M10B with nominal post-LOCA initial conditions'with only the two PCC condensers connected to Drywell 2 operational and all steam flow directed through the steam line from the RPV to Drywell I to create asymmetric distributions of steam and non-condensable gas concentrations and demonstrate the PCCS/ containment performance under these conditions, i.e. maximum non-condensible gas volume purge rate through each PCC (total volume of DW1 and DW2 through two PCCs).

' 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 Section 3 of PSI report ALPHA 410. For Tests M2, M10A & M10B the PANDA facility will be configured to simulate the SBWR post-LOCA configuradon as follows:
1) Table 4.1 identifies the key PANDA facility geometry and effective flow area ( A /[i) characteristics. In Table 4.1, the required tolerance for the PANDA as-built value reladve to the corresponding'SBWRscaled value is tabulated for each of these key characteristics. In addidon, the required accuracy for the as-built value for each of the key characterisdcs 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 Electorwatt (i.e.

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

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

2) The RPV will supply steam to the dqwells as follows:

a) For test M2 & M10A the RPV will supply steam only to Dnwell 2 through its single connecting steam line.

l b) For test M10B the RPV will supply steam only to Drywell 1 through its single connecting steam line.

3) RPV heater power will be controlled as a function of time to simulate the scaled decay heat and stored energy release.
4) The IC unit will be isolated (i.e., the IC feed, drain and vent will be closed).
5) The PCC units will be lined up as follows:

a) For test M2 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.

b) For tests M10A & M10B only the two PCC units connected to Drywell 2 will be lined-up to take feedflow from the drywell, to vent noncondensables and steam into the water volume of the suppression pool, and drain condensate to the GDCS volume.

S

25A5785 sH No. 6 EN asv. 0

6) The PCC pools will be configured as follows:

a) the PCC pools will be filled and isolated from each other.

b)During the test, no water will be added or drained from the PCC pools.

7)

The only direct lines of communication between the drywell and wetwell will be through the vacuum breakers (when the werwell pressure exceeds drywell pressure sufficiently to' open the vacuum breaker) and the main vent lines (which will be submerged within the wetwells).

8) The GDCS pressure eqi 21iradon lines to both drywells will be open.
9) The GDCS drain line with check valve will be lined 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 tmnsient 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. Folkswing test inidadon, 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 Dnwell/Wetwell Vacuum Breaker Control The operation of the vacuum breaker valve will be controlled based on the measured pressure difference between the drywell 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-tcxitywell differential pressure at which the vacuum breaker for Dnwell 1 opens will be set at 0.47 psi (3.24 kPa), and the differential pressure at which the vacuum breaker for Dnwell I closes will be set at 0.3 psi (2.06 kPa). The opening and closing differential pressure for the vacuum breaker in Dnwell 2 will be set 0.1 psi higher than the corresponding'setpoints for the Drywell I vacuum breaker, i.e. at 0.57 psi (3.9 kPa) and 0.4 psi (2.8 kPa), respectively.

REO_UIRED MEASUREMENTS

'able 6.1 gives the measurements required to meet the objectives for Tests M2, M10A & M10B.

dith the exception of the temperature indication, no PANDA instrumentadon other than that in i

Table 6.1 is necessay for the performance of Tests M2, M10A & M10B. The sensors identified in Table 6.1 must be operable prior to initiation of these tests. It is acceptable if'a sensoris not operable, if the backup identified in the second column is operable.

Temperature measurements in the PCCs and the various connected vessels are desirable, but not all of these tempemture 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 tubes; (It is required that 50% of the tube wall and fluid sensors be available. The available sensors must include at least 40% of the probes above and at les.st 40% of the probes below the hodzontal mid-plane of the tube bundle. Within these constmints, the test engineer has responsibility and authority tojudge whether or not suficient PCC

{

temperature sensors are operable to initiate a test).

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

DW: 50% of the fluid probes including either the lowest elemtion 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 floating probes.

GDCS pool: 50% of the fluid probes and one thermocouple from the floating 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 identified as " top priority measurernents".

Time histon plots of these top priority measurements are to be included in the Test File (see Section 7.3) and the Apparent Test Results (ATR) Report (see Section 10). In addition to the top prionty measurements identified in Table 6.1, there are other top priority measurements. These are: 1) the total electrical power to the heaters in the RPV which is determined during post-test I

25A5785 sH so.14 ED arv. O data processing, and 2) some temperature measurements. The top priority temperature 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 measurement in 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 perforinance. These cheeks 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 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 1 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 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 be createrl 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 on-off 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 are working correctly.

TEST MATRIX 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 (s).

' The drywells, wetwells, GDCS tank and PCC pools will be pre <onditioned and brought separately to their required initial conditions (or slightly higher temperatures and/or pressures if heat loss or stabilization is expected to bring conditions within their required range).

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:

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, within a period of approximately 5 minutes.

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

The following describes contingency testing to be done after 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> in test M2 as follows:

a. at 20 hr, increase the power to 800 kw.
b. after the system has reached a quasi-steady state condition, close the feedflow line to one of the PCCs. This PCC should be one which is removing the most heat as evidenced by the actual PCC pool level response.
c. after the system has reached a quasi-steady state ' condition, data recording may be terminated, and the test performance declared complete.

Notes:

-(1) Water levels are specified relative to the top of the PANDA heater bundle.

(2) The nominal DW condition is no water. However, a small amount of spill from the RPV to the DW at the start of the test is acceptable.

(3) The GDCS level should be positioned in hydrostatic equilibrium with the RPV level (including an appropriate adjustment for temperature difference).

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 summanze the apparent results. The format for this repon will include: test number, test objective, test date, data recording period, names of data files, list of failed or unavailable instnnnents 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 measuremenu over the test duration.

The ATR repon is a verified report, approved by the PSI PANDA Project Manager, and will be 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 M2, M10A &l0B will be issued approximately two months after the last test is performed. It will provide detailed 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.
