1. SCOPE This test plan defines the detailed requirements, beyond those already identified in GE Spec 25A5587, for the PANDA transient integral system tests M9. This Test Plan specifically covers the test program objectives, the experimental facility configuration, the test facility control, the test instrumentation, the data acquisition, processing and analysis, the test initial and boundary conditions and the test reports for test M9.

This test plan is applicable to the SBWR Design Certification project only.

3. TEST OBJECTIVES The objectives of the PANDAintegral 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 and approach for the tests covered by this test plan are given below:

The objective is to perform test M9 with conditions simulating the transition from the GDCS injection phase to the long-term PCC cooling phase of the post-LOCA transient.

The approach to meet these objectives will be to set the GDCS initial conditions (level and temperature) and RPV conditions (initial water level and power through the test) to obtain containment behaviors (e.g. drywell pressure change, vacuum breaker operation) which are representative of the SBWR during this transition period.

4. TEST FACILTIY CONFIGURATION The PANDA test facilityis described in detailin Section 3 of PSI report ALPHA 410. For Test M9 the PANDA facility will be configured tc simulate the SBWR post-LOCA configuration as follows:
1) Table 4.1 identifies the key PANDA facility geometry and effective flow area ( A / /k )

characteristics. In Table 4.1, the r quired 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 Electrowatt (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 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 create conditions similar to the early phase of the GDCS injection after which it will be ramped back 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) 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 will be filled and isolated from each other. During the test, no water will be added or drained.
7) The i ly direct lines of communication between the drywell 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 drywells will be open.
9) The GDCS drain line with check valve will be lined up to return PCC condensate to the RPV l

as part of the test initiation sequence.

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

CONTROL SYSTEM DESCRIITION In order to perform the transient integral system tests, several control systems are to be used to establish initial and boundary condidons 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 IIeater Power Control During the test initiadon the electrical power to the RPV beaters will be placed in automadc control to follow the curve specified in Section 9. This power together with the GDCS conditions will give representative RPV steam flow to the drywells during the GDCS injection phase of the LOCA after which it will match the scaled decay pc.

and RPV structural heat release of the base case test MS.

5.2 Drywell/Wetwell Vacuum Breaker Control The operation of the vacuum breaker valves will be controlled based on the measured pressure difference between the dqwell 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 both valves between the dnwell and wetwell volumes. The wetwell-to-drywell differential pressure at which the vacuum breakers open will be set at 0.47 psi (3.24 kPa), and the differential pressure at which the vacuum breakers close will be set at 0.30 psi (2.06 kPa).

REOUIRED MEASUREMENTS Table 6.1 gives the measurements required to meet the objectives for Test M9. With the -

exception of the temperature indication, no PANDA instrumentadon other than that in Table 6.1 is necessary for the performance of Test M9. The sensors idendfied in Table 6.1 must be operable prior to initiation of these tests. Itis 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 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 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

o 25A5824 sH No.13 GENucienerEnnwgy nev. 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 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 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 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 perfonn 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, i

measurement channel number and sampling frequency) j

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 i

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-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 confinned 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 configuradon in Section 4, except the valves in the RPV to drywell steamlines and GDCS drain line valve, within a period of approximatel 5 minutes.

f

1) place RPV heater controls in automatic operation to follow the time dependent heater power determined from the specification in Table 9.2.
2) after heater energization perform the following

- open the valves in both RPV to drywell steamlines

-open the GDCS drain line valve From this point on for test M9 there are no further operator actions, at the end of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> data recording may be terminated and the test declared complete.

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 completion of each transient integral system test.

The Data Transmittal Report (DTR) containing all data for transient integral system test M9 will be issued approximately two months after the last test is performed. It will proside 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.

11.

TEST HOLD / DECISION POINTS The Test Procedure (s) must have been reviewed and approved by GE's Project Manager, GE Site QA Representative and PSI's PANDA Project Manager before the transient testing described in Section 9 can be performed.
