e. PANDA PROJECT CONTROL PLAN, GE Doc.

PPCP-QA-01.

This document describes the organization, quality related activities, events and procedures necessary to ensure and verify that the PANDA project at PSI is conducted under the provisions of the GE SBWR Quality Assurance Plan as described in NEDG-31831.

3 TESTOBJECTIVES 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. (IntegmlSystems Tests)and (b) Demonstrate startup and long-term operation of a passive containment ccoling system.

(ConceptDemonstmtion).

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

a) Conduct tests (MS, M3A, MSB and M4) with nominal post-LOCA conditions to establish the l base case and demonstrate transient system response and repeatability.

b) Perform test M7 with drywell and PCC units initially filled with air to provide data to determine the PCC condenser start-up characterisdcs when blanketed with noncondensable gas.

4. TEST FACILIT/ CONFIGURATION The PANDA test facility is described in detail in Section 3 of PSI report ALPHA 410. For Tests M3,MSA, M3B, M4 and M7 the PANDA facility will be configured to simulate the SB%R l

post-LOCA configuration as follows:

1) Table 4.1 identifies the key PANDA facility geometry and effective flow area ( A /8) characteristics. In Table 4.1, the required tolerance for the PANDA as-built value relative to the corresponding SBWR 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 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).

c, g

25A5764 su No.5 W

GENuclearE=yy "2

2) The RPV will supply steam to each drywell with two steam lines (one to each dqwell). 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 and stored energy release.
4) The IC unit will be isolated by closing the inlet and outlet valves (i.e., the IC feed, dmin and j

vent will be closed).

5) All three PCC units will be lined-up to take feedflow from the dqwells, to vent noncondensables and stean) into the water volume of the suppression pool, and drain condensate to the GDCS volume.
6) The PCC pools and IC pool will be configured as follows:

a) For Test M3 the PCC pools will be interconnected at the bottom. During the test, no 1

water will be added or drained from the pools.(note this test has been run based on 25A5764 Rev.1) b) For Test MSA the PCC pools and IC pool will be isolated from each other. During the test, water will be added to the PCC pools, as needed, from the bottom to maintain level.

c) For Test M3B the PCC pools and IC pool will be interconnected at the bottom. During the test, water will be added to the pools via the interconnecting bus line, as needed, from the bottom to maintain level.

1 d) For Tests M4 & M7 the PCC pools and IC pool configuration will be based on an evaluation of the system performance displayed during MS, MSA, MSB. If MSA and M3B results are evaluated as essentially the same then M3B will fulfill the requirements of Test M4 and will be designated as Test M4 and Test MSA will constitute the base case test for all subsequent testing.

7)

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

8) The GDCS pressure equalization lines to both dqwells 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 sersice.

CONTROL SYSTEM DESCRIPTION l

In order to perform the transient integral system tests, several control systems are to be used to establish inidal 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 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 wenvell pressure drops below a minimum value the vacuum breaker valve control will automatically open the valve. The wetwell-to<inwell differential pressure at which the vacuum breaker for Drywell 1 opens will be set at 0.47 psi (3.24 kPa), and the differendal 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 breaker in 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.

5.3 PCC/IC POOL LEVEL CONTROL i

The PCC and IC pool level control, when applicable, will be via manual operator action to line-up the auxiliary water system and feed water from the demineralized water supply system into the bottom of the pools while monitoring the pool level indication.

REOUIRED MEASUREMENTS Table 6.1 gives the measurements required to meet the objectives for Tests M3,M3A, M3B, M4, l

and M7. With the exception of the temperature indication, no PANDA instrumentation other than that in Table 6.1 is necessary for the performance of Tests M3,MSA, MSB, M4, and M7. The l sensors identified in Table 6.1 must be operable prior to initiation of these tests. It is acceptable if a sensor is 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 temperature meassrements 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 (atleast 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 least 40% of the probes below the horizontal mid-plane of the tube bundle. Within these constraints, the test engineer has responsibility and authority tojudge whether or not sufficient PCC temperature sensors are operable to initiate a test).

PCC 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 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 measurements".

Time history 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 priority 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

25A5764 s u o.13 gg nsv. 2 data processing, and 2) some temperature measurements. The top priority temperature RPV steam dome temperature measurement, highest and lowest temperature measurements are:

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 performance. These checks will include comparison of redundant measurements. In addition, the oxygen sensors will be checked out prior to transient test M3 using the PSI procedure ALPHA 502.

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 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 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 created in order to have a backup record of the data file. Also to be recorded with this data file are all information 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 (idendfication, 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<>ff 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.

25A5764 SH No.19

@hUeG.yf REV. 2 Following completion of the tests described in Section 9, data reduction will be performed to support preparation of the Apparent Test Results Reports (ATR). This data reduction will include a representative set of dme history plots of system flows, differential pressure, vessel pressures, air partial pressure (O2 sensor readout), and temperatures covering the full test duration for top priority measurements. These results will be reviewed and reported in the ATR (see Section 10).

The Data Transmittal Rg rt (DTR) will transmit all the data for the transient integral system tests (see Section 10).

SHAKEDOWN TESTS 8.1 Purpose The purposes of the shakedown tests are to:

- confirm test facility ability to establish a quasi-steady state set ofinitial conditions

- confirm adequacy of data acquisition system

- confirm ability to achieve a smooth but rapid transition between the pre-test initial conditions line-up to the test line-up

- confirm the adequacy of the test procedures.

The PANDA facility will be configured as described in Section 4. The reference test numbers are from Section 9. The detailed test procedure with its check lists are contained in die PANDA Transient Integral System Test Procedures for Tests MS and M4 (ALPHA-520) and Test M7 (ALPHA-521).

8.2 Description Test SDM-01 will be donc per the test procedure for Test M3 using the initial conditions specified for Test MS. The focus of the shakedown test will be to evaluate 1) the procedure for achieving test initial conditions,2) the procedures to initiate the test, and 3) the capability of the data recording system, the power control system, etc to perform as required throughout the transient test duration.

The procedure as drafted in ALPHA-520 Rev. A will be used, and modifications will be introduced as needed. These modifications will be incorporated into the final procedures, ALPHA -520 & ALPHA-521, to be issued prior to initiation of Tests M3, M4 and M7, as applicable.

25A5764 sH No.21 gg REV. 2 9.

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 the detailed procedures in ALPHA-520 and ALPHA-521. The following summarizes the test procedure.

The drywells, wetwells, GDCS tank and PCC pools will be pre-conditioned 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:

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.

i From this point on the only operator action regarding test facility configuration or conditions will be as follows:

4 For Test M3 there are no further required operator actions.

For Test M3A and M3B the only operator actions will be the maintenance of the PCC pool levels.

i For Test M4 and M7 the required actions will be determined from the evaluation of the M3 series tests.

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 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.

The ATR report is a verified report, approved by the PSI PANDA Project Manager, and will be transmitted to the GE within approximately two weeks of the compledon of each transient integral system test.

The Data Transmittal Report (DTR) containing all data for transient integral system tests M3, MSA, M3B, M4, M7 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
