25A5764 su so.4 gg arv. 3 k TESTOBECTJyff The objectives of the PANDA integral systems tests are to provide additional data to: (a) provide a sufficient database to confirm the capability ofTRACG to predict SBWR containment system performance, including potential systems interaction effects. (IntegelSystems Tats)and (b) Demonstrate startup and long-term operation of a passiw containment cooling system.

(ConceptDemonstation).

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

a) Conduct tests (MS, MSA, MSB and M4) with nominal post-LOCA conditions to establish the base case and demonstra:e 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 characteristics when blanketed with noncondensabic gIS*

4. TEST FACIIJIYCONFIGURATION 1

The PANDA test facilityis described in detailin Section 3 of PSI report ALPHA 410. For Tests MS,MSA, MSB, M4 and M7 the PANDA facility will be configured to simulate the SBWR post-I.OCA configuration as follows:

1) Table 4.1 identifies the key PANDA facility geometry and efTective flow area ( A /8) characteristics. In Tabic 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 Tabic 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.

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

PCC/1C tubes), or calculations from as-built dimensions (i.e., vessel volumes, losses for lines without flow tests).

i

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

two steam lines will have the same pressure loss characteristics.

i

3) RPV heater power will bc controlled as followv a) For tes:s MS, MSA, MSll, & M4 RPV heater power will be controlled as a function of time to simulate the scaled decay heat and stored energy release as indicated in Tahics 9.2a &

9.2b.

b) For test M7 RPV beater power will be established and held constant at a value of 1.13 MW

^

4) The IC unit will be isolated by closing the inlet and oudet vahrs (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 and IC pool will be configured as follows:

a) For Test MS the PCC pools will be interconnected at the bottom. During the test, no 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 filled and isolated from cach other.

l During the test, orater will be added to the PCC pools, as needed, from the bottom to maintain level.( note this test has been run based on 25A5764 Rev. 2)

i G<

25A5764 SH NO. 6

{

gg av. S c) For Test MSB the PCC pools and IC pool will be filled and interconnected at the bottom. l During the test, water will be added to the pools via the interconnecting bus line, as needed, from the bottom to maintain level.( note this test has been run based on 25A5764 Rev. 2) d) For Tests M4 the PCC pools and IC pool configuration will be based on an evaluation of the system performance displayed during MS, MSA, MSB. If MS, MSA and MSB results are evaluated as essentially the sarse then MSA or MSB will fulfill the requirements oftest M4 and will be daignated as Test M4. Ifit is determined that test M4 needs to be run, the configuration for the pools will be specified by revision to this Test Plan.

c) For Tests M7 the PCC pools will be filled and irolated from each other. During the test, no water will be added or drained from the pools.

7)

The only direct lines of communication between the drywell and wetwell will be through the vacuum breakers (when the wtwell 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 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 Ute RPV,
10) The Equalizing lines between the RPV and wetwells will be valved out of senice.

CONTROL SYSTEM DESCRIPTION In order to perform the transient integral system tests, several control systems are to be used to l

establish initial and boundary conditions for each test. These control systems will be used to l

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 pour 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 ofa 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 difTerential pressure for the vacuum breaker in Drywell 2 will be set 0.1 psi higher than the corresponding setpoints for the Drywell I vacuum breaker, i.e. at 0.57 psi (S.9 kPa) and 0.4 psi (2.8 kPa), respectively.

5.3 PCC/IC POOL LEVEL. CONTROI.

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

REOUIRFD MEASUREMENTS Table 6.1 gives the measurements required to meet the objectives for Tests MS,MSA, MSB, M4, and M7. With the exception of the temperature indication, no PANDA instrumentadon other than that in Table 6.1 is necessary for the performance of %-ts MS,MSA, MSB, M4, ar'd M7. The sensors identified 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 identified in the second column is operable.

Temperature measurements in the PCCs and the various connected vessels are desirab!c, 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 tht. horizontal mid-plane of the tube bundle. Within these constraints, the test engineer has responsibilityand authority tojudge whether or not sufUcient PCC temperature sensors 1 ire 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 elevadon or one thermocouple from de water-surface probc.

WW: 50% of the gas probes,50% of the liquid probes and two out of three of the floadng probes.

GDCS pool: 50% of the fluid probes and one thermocouplc from the floating probe.

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

1 System lines: 50% of the gas and liquid temperature probes in each system line used for i

the test (ifnumber ofsensors is odd, round to lower whole number,i.e. S sensors totalin l

one line means one is required).

In Tab!c 6.1 a subset of the required instruments are identified as " top priority measurennents".

Time history plots of these top priority measurements are to be included in the Test File (see Section 7.S) and the Apparent Test Results (ATR) Report (see Secdon 10). In addition to the top priority measurements identified in Tabic 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 data processing, and 2) some temperature measurements. The top priority temperature measurements are: RPV steam dome temperature measurement, highest and lowest temperaturc measurement location in cach drywell, highest and lowest temperature measurement location in the gas space of each wetwell, highest liquid temperature rncasurement location in each wetwell, and one temperature measurement in the GDCS drain line and in each of the three PCC vent lines.

DATA RECORDING. PROCFMING 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 sampics per minute. During the rest of the test (after the peak drywell pressure is reached) the data will be recorded at 1 sampic per minute. It is necessary that the data sampling rate be suflicient 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 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 cengruency checks including zero checks as possible to verify that the instrumentation and data acquisition system are working correctly.

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 time history plots of system flows, differential pressure, vessel pressures, air 1

SRAKFDOWN TFSTS 8.1 Purpose The purposes of the shakedown tests are to:

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

- confirm adequacy of data acquisition system

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

. confirm the adequacy of the test procedures.

't 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 the PANDA Transient Integral System Test Procedures for Tests MS and M4 (AI.PHA-520) and Test M7 (ALPHA-521).

8.2 Description Test SDM41 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 condidons,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.

TFST 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 AI.PHA-521. The following summarizes the test procedure.

The drywells, wetwells, CDCS 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 9.3, 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 vahes in the RPV to drywell steamlines, within a period of approximately 5 minutes.

Then, the following sequence should be performed as quickly as possib!c:

1)

Open the valves in both RPV to drywell steamlines 2) a) For M3, MBA, MSB & M4 place RPV heater controls in automatic operation to follow the time dependent heater powerdetermined from the specification in Table 9.2.

b) For M7 establish RPV heater power operation for a value of 1.13 MW From this point on the only operator action regarding test facility configuration or conditions will be as follows:

For Test M3 & M7 there are no further required operator actions.

For Test MSA and MSB the only operator actions will be the mainterance of the PCC poollevels.
