1.0 INTRODUCTION

I i

l The AP600 is a pressurized water reactor (PWR) that uses an automatic depressurization system l (ADS) to ensure that the reactor coolant system (RCS) is depressurized, thereby initiating and maintaining long-term gravity injection. He AP600 ADS consists of two independent piping I flowpaths from the top of the pressurizer, each going to a quenching device or sparger that is submerged in a water-filled portion of the reactor containment structure. Each of these two piping flowpaths is made up of a 14-in. pipe from the pressurizer, which connects to three parallel paths (4.,8 , and 8-in.). These three parallel paths each have two normally closed valves in series. The three parallel paths connect to a single 16-in. discharge line that ends at a submerged sparger. When the ADS is operated, the closed valves are sequentially opened to provide a staged, controlled depressurization of the RCS from operating conditions at 2250 psia /650 F to saturated conditions at

~25 psia. He AP600 ADS operation for each stage consists of first opening the upstream (isolation) valve, followed by the opening of the downstream (flow control) valve.m he ADS phase B test is a full-sized simulation of one of the two AP600 ADS flowpaths from upstream of the ADS valves to the sparger and is intended to duplicate or conservatively bound the operating conditions of the AP600 ADS valves and sparger. The ADS phase B test has been performed at ENEA's VAPORE test facility in Casaccia, Italy, where the phase A portion of the ADS test was also performed. This phase B test program is subdivided into two portions, B1 and B2. The B1 tests were the overall system performance tests and were performed with the ADS valves (or simulated valves) fully opened. Flow initiation in this El portion of the test was accomplished by valves upstream of the actual ADS piping ring. The B2 portion of the ADS test was performed separately to demonstrate ADS valve operability. Both the B1 and B2 portions of the test included blowdowns through a prototypic sparger, submerged in a quench tank; with either saturated steam from the top of the VAPORE steam / water supply tank or with saturated water from the bottom of the supply tank (see Figure 1-1).

This test specification provides the requirements for the B1 portion of the ADS phase B testing program,i.e., overall system performance verification. The B2 portion of the test program, valve

, operability verification, will be discussed separately.

-- 2.0 L PHASE B1 TEST PROGRAM OBJECTIVES

' The test objectives of the B1 portion o'fthe ADS test are:

1 Collect thermal-hydraulic performance data with both single-phase steam and two-phase  !

steam / water flow to support development and verification of the analytical model of the ADS e- to be used in safety analyses evaluations of events for which the ADS is actuated.

l

• Verify the design and proper operation of the ADS sparger over a range of single-phase steam and two-phase stetm/ water flow rates.  ;

l

• Obtain additional quench tank pressure impulse data to verify the analytical model used to establish the in-contaimnent refueling water storage tank (IRWST) structural design over a

- range of single-phase steam and two-phase steam / water flow rates.

• Simulate the AP600 plant piping (including elbows, tees, etc.) and ADS valves to identify / characterize the flow conditions that occur during full flow ADS operation over a range of single-phase steam and two-phase steam / water flow rates.

l 3.0 PHASE B1 FACILITY REQUIREMENTS The test facility for phase B (see Figures 1-1 and 5-1) of the automatic depressurization test shall have the following capabilities:

Provide an isolable scurce of saturated steam at pressures and tetpratures typical of the AP600

+

reactor conditions to achieve prototypic volumetric flow rates expnted during ADS operation.

Figure 3-1 provides the saturated steam mass flowrate anticipated to initially occur when the ADS valves on the AP600 pressurizer are opened at 2250 psia.

Provide an isolable source of saturated water at pressures and temperatures typical of the AP600 reactor conditions so as to achieve (or conservatively bound) prototypic volumetric and mass flowrates through the ADS. In the AP600 plant, the initial steam flow from the pressurizer will be followed by low c.aality steam or saturated water that flashes. Figure 3-2 shows a conservative ant:cipated mar aow (unthrottled) through each individual ADS valve and through combined valves, which have a choked flow of saturated water through fully open ADS valves.

• Provide a tank that contains water in which the sparger can be mounted in order to simulate the AP600 quench tank. (See Section 4.0 for additional information.)

Provide acceptable thermal and dynamic stresses of piping and valve during ADS testing. For example: Figure 1-1 shows piping connections to preheat the piping upstream of the ADS valves.

'Ihe common discharge piping to the sparger may require expansion bellows and position adjustment devices.

Provide purging of air from the discharge piping using steam so that sparger air clearing loads are minimized when and if test full-flow conditions are initiated over a shorter than prototypic time.

Provide adequate space for the ADS valves, piping, and required supports and instrumentation such that the test can be constmeted and operated with efficiency and safety.

Provide an isolable source of pressurized, saturated steam and water at 2500 psia (172 bar) to

, achieve flow conditions (pressure, temperature, steam quality) at the ADS valve / piping ring that simulate the AP600 ADS.

Provide slow-operating motor-driven actuators that use 120 volt de electrical current provided by batteries. (Note: Motor-diven actuators for the test valves will be fast-operating (~15 sec.) and will use 380 volt,50 HZ, three-phase electrical power supply.)

Provide an appropriate instrumentation and data acquisition system (DAS) that can sample data at

-1000 samples per second to record pressure pulses that have dominant frequencies as high as 100 HZ.

4.0 PHASE B1 TEST ARTICLES Sparger A full-size sparger tested in the ADS phase \ testaa53 shall be used in this ADS phase Bl test. He mechanical force and moments on the sparger arms are to be measured during sparger operation using >

o strain gauges and pressure measurements inside the sparger. Movie or video recordings of sparger and quench tank operation are to be made. Note that the sparger inlet connection is 14-in., Schedule 80 as opposed to the current AP600 design,in which the sparger inlet is 16-in. diameter pipe (see Figures 5-1 and 5-2).

Quench Tank (Simulated IRWST)

The quench tank containing the sparger shall be cylindrical in shape and have rigid walls. Tank requirements are provided below.

= Minimum tank wall height - 28 ft. (8.53 m).

Minimum tank dimneter - 23 ft. (7.0 m).

. Open top for unrestricted venting.

. - Provision for heating the contained water and capable of testing at saturated conditions

(~212'F)/(100*C).

• Capability to withstand cyclic pressure loads generated by the sparger.*

• Capability to mount required instmmentation for pressure and temperature measurements in the contained water as shown in Figure 5-3.

4 Sparger Pedestal An 8.5-ft. (2.6-m) long sparger pedestal shall be provided by Westinghouse.5) His pedestal will be used to raise the sparger in the quench tanks so that it is submerged 9.5 ft. (2.9 m) below the water surface (the same depth as in the AP600 plant) when the quench tank water level is 24 ft. (7.3 m).

De pedestal shall be instrumented with strain gauges to verify that forces imposed on the pedestal during sparger operation are acceptable.

l Valves

. Note that only one of two valves in series for each stage of AP600 ADS will be included in the phase Bl test. Rese valves will not be operated (opened or closed) with the piping pressurized or mAmp600%o986V)986w.non

5.2 Valve Instrumentation In addit'on to the above process instrumentation, ITI MOVATS has been contracted to install

. additional instrumentation on the installed valves. MOVATS will also provide two 16-channel data acquisition systems (DASs) to monitor the baseline (initial) operation of the installed valves provided by Westinghouse for the BI' portion of this test (i.e.,4-in. globe, two 8-in. gates, and two 12-in. gate valves); and to monitor the operation of the 12-in. gate valves during the B1 tests.

The MOVATS valves monitoring service shall include:S

=

.. Baseline measurements (performed on all valves prior to any tests with flow and AP, and on 12-in. gate valves after tests are completed) stem thrust and totgue during open and close strokes (includes seating and unseating) motor power (current and voltage neasured) spring pack displacements continuous valve position versus time Measurements during test operations (performed for 12-in. gate valves only) stem thrust and torque during open/close strokes motor power spring pack displacements valve position versus time open and close limit switch actuations upstream and downstream pressure

'Ihe MOVATS valve DAS must interconnect with the process DAS for some valve signals, including the valve limit switches actuations and pressure measurements. The MOVATS DAS data shall be transmitted to Westinghouse AP600 test engineering by the Westinghouse site engineer.

5.3 Other Instrumentation o

Eight strain gauges are to be mounted on sparger arms A and B at four positions, each corresponding to 0,90,180, and 270 degrees from vertical, in line with the arm axis, as was done in the phase A test.m Four strain gauges (XE-1 thru XE-4) are to be mounted on the sparger pedestal with a vertically and horizontally oriented gauge placed at a 90 degree circumferential spacing.

Sixteen strain gauges are to be placed on the ADS valve / piping ring. The locations of the above strain gauges are shown in Figure 5-2, as specified by Ansaldo.

6.0 DATA ACQUISITION SYSTEM A data acquisition system (DAS) shall be provided that includes the equipment necessary to monitor and transmit the output signals generated by the various instruments used both in the control and monitoring of the test loop.

DAS Components The DAS is taken to include those signal amplifiers, signal conditioners, signal transmitters, signal conveners (analog-to-digital and others that may be used), switch panels, interface electronics, computers, power supplies, displays (CRT, strip chart recorders, gages, etc.,), power suppliec, and interconnected wiring, as needed to accomplish the test.

Input Channels The DAS shall rece.ive analog signals from various temperature an 1 pressure sensors, flow meters, accelerometers, valve position indicators, and other instrumentation used for test operation and monitoring, and record them in a digital form. Shielded wiring shall be used for all signal input leads to minimize the pickup of noise in the signal. High-frequency filters may also be used, where shown to be appropriate and agreed to by the tett sponsor.

The test performer shall be responsible for ensuring that the DAS is capable of accepting and processing the range of output signals that can be generated by the various instniments that may be used during the course of testing.

Sampling Rates The sampling rate of the instniments by the DAS shall be set by the physical phenomena being monitored and the response time of the instrument itself. To monitor rapidly changing or oscillating phenomena, rapid scanning rates are desired, while fewer scanning rates are acceptable for slower phenomena or slow response instnaments. Thus, to provide for the efficient collection, storage, and handling of meaningful and useful data, the DAS may sample different instruments at different rates

, during the course of a test. He sampling rate required for the piping, sparger, and quench tank pressure transducers is to be 1000 samples per second.

Online Data Storage The DAS shall have sufficient storage capacity to capture and store all digital data collected from a given test. He maximum duration of a test is not expected to exceed 10 minutes.

mhp60009860986w.non:Its031495 61

~

i i

- The data shall be stored by the DAS in engineering units (pounds per square inch or pounds per second or 'F). The conversion from the actual instrument outputs (millivolts, milliamps, etc.,) to engineering units shall be documented. ,

Online Display The DAS shall provide for the continuous online display of selected instruments or calculated test parameters before (pretest), during, and fol!owing (post-test) each test performed. In general, the-

- information displayed shall be sufficient to allow the test loop operators to assess the following:

• Initial test loop conditions meet those specified

+ No uncxpected test events that might negate the test have occurred 'l All data displayed'online sball be in the appropriate engineering units; temperature, pressure, flow, and  ;

quality, as applicable.  ;

The online display shall be by CRT, and an echo to a print file for inclusion in day-of-test reports is desirable.~

Test Raviese The DAS shall have the ability to perform a post-test data review on the test performed. The purpose of the check will be to determine quickly whether a test needs to be re-run. A more detailed test acceptance check shall be performed later by the test sponsor. In general, a successful test shall satisfy the following three criteria: l

• Sufficient instrumentation must be operable and recorded by the DAS to permit average mass flow and steam quality to be calculated for the facility.  ;

• Sufficient instrumentation must be operable and recorded by the DAS to ensure that the data needs addressed by the test are satisfied. .

i

• Test conditions should reasonably match those called for in the test matrix. For example,

[ ,

l '

initial pressurizer pressure should be 5 percent of the specified pressure, motor-operated  :

valve opening times should be 20 percent of specified values.

To guide in determining test success, the " check list" shown in Table 6-1 shall be used. The check lists' and associated plots shall be printed post-test, along with a summary of other instrument outputs that are determined to be critical to a successful test or that demonstrate deviations or unusual behavior, for review by the cognizant test engineer in assessing test validity.

m:\np600098610986w.non:Ib-031495 6-2

Data Transmittal ~

Following post-test data review, the test data shall be provided to the Westinghouse Electric Corporation on 'an optical CD. As a minimum, the data tape is to contain the following information:

4

• Test run file header, containing the test nm ID, date, and other pertinent information.

Channel assignment table, associating instruments with specific DAS channels and identifying other information pertinent to instrument identification.

Calibration file, containing all information necessary to secount for shifts in zero settings and

- convert raw instrument outputs from volts to engineering units.

• All the data from one channel, presented one channel at a time.

Test Acceptance

'Ihe data from each test shall be assessed by the test sponsor to determine test acceptability. Tests that do not meet the acceptance criteria may be re-tun, as requested by the test sponsor. The acceptance

- criteria are:

Mass flowrate shall be able to be calculated based upon pressurizer mass / level measurement (saturated water blowdowns only). +

+ _ Redundant pressurizer mass / level measurements shall agree within ten percent (saturated water blowdowns only).

Achieved mass flow and steam quality shall be in close agreement with the test intent. The basis for this criterion will be the relationships ofintended and achieved conditions to predicted AP600 plant conditions, as shown on mass flowrate/ quality " maps" (saturated water blowdowns only).

~ Mass flowrate shall be able to be calculated with uncertainty less than 10 percent, based on

, venture; flowmeter differential pressure measurement (steam blowdowns only).

• Critical instruments shall function properly.

'Ihe PROSIG and IBM DASs shall record data properly,i.e., for the eritire transient.

. Initial pressurizer pressure shall be within i 5 percent of the specified pressure.

Initial quench tank temperature shall be less than or equal to 140*F (except " hot quench tank i

, tests).

7.0 TFST OPERATION -

. The operation of the test facility shall be established and documented in test operating procedures.

These last operating procedures are to be provided by ENEA, the testing organization, and submitted

to Westinghouse for review and approval with the exception of the cold pre-operational valve baseline test described below (see Section 9.0, Quality Assurance Requirements). Operating procedures shall be prepared for but not limited to the following tests

7.1 Cold Pre-Operational Tests

. Valve Baseline Tests Each of the valves installed in the ADS test piping for the phase B test program shall be stroked open and stroked closed at least three times each. These initial valve open/close strokes shall be performed at ambient pressure and temperature conditions (no AP scross the valve seats), after the valves have

. been instrumented.

Baseline valve stroke data shall be obtained for these valves:

• 12-in. Edwards gate valve

• 12-in. Atwood & Morrill gate vr.tve

. 4-in. Anchor-Darling globe valve

. 8-in. Anchor-Darling gate valve

= 8-in. Westinghouse gate valve Note: Valve instrumentation and measurement devices shall be installed on each valve by ITI MOVATS (a Westinghouse subsidiary). ITI MOVATS shall record and report the thrust / torque measurements as well as other pertinent valve information.* Also, ITI MOVATS shall

. supervise / perform these baseline valve tests, therefore ENEA procedures are not required.

- Atwood & Morrill Valve Resistance Data As described in Section 7.3 below, the Atwood & Morrill (A&M) 12-in. gate valve shall be set at a

-- partially open position during blowdown tests in which saturated water is taken from the bottom of the steam / water supply tank. 'In order to document the valve resistance at partially open positions, a cold water, low pressure flow test shall be performed at the following A&M valve flow areas:

0.7 in.2,1.4 in.2, 2.1 in.2, 3.5 in.2, 5.25 in.2, 7.0 in.2,12.5 in.2,14.0 in.2,17.5 in.2, 21.0 in.',

28.0 in.8 These resistance tests shall be run at low pressure ,<29 psig (2 bar,) in the steam / water supply tank.

ENEA shallinstall a temporary AP instmment across the A&M gate valve for these tests. The m:\ap60009860986w.non:Ib.031495 7-1 ll , ._

1 flowrate through the valve shall be determined by measuring the change in the steam / water supply tank water level versus time. De actual valve disk position shall be measured and recorded by inserting a boroscope into each side of the valve body.

~

Note: The boroscope observations shall include measurement of any " free play" between the valve stem and the valve disks. Also, an accurate method of physically verifying the actual valve stem position shall be provided.

i These tests shall be conhted by filling the steam / water supply tank with cold water, thus compressing air to provide the driving pressure. Flow shall be initiated by opening the 12-in. Edwards gate valve. Water / steam supply tank level versus time and pressure versus time data shall be recorded for at least one minute. Flow shall be terminated by closing either the 12-in. Edwards gate valve or A&M gate valve.

7.2 Facility Acceptance Tests Ansaldo has modified the VAPORE facility for ENEA to perform the ADS phase B test under a separate contract with ENEA. Ansaldo shall perform acceptance tests to document contract completion. These tests shall be specif: I by Ansaldo/ENEA. For information only, the anticipated acceptance test includes:

• Facility hydrotest(s).

• Piping and support thermal response tests with both slow and fast heatup rates.

• Modcrate energy saturated water blowdown tests with high mass flowrates at 200,350, and 500 psig supply tank pressures.

Note: Leakage through the 12-in. valves shall be measured prior to and after each test.

• ADS valve opening at high pressure that can be performed after installation of the 8-in. .

ADS control valves (after completion of the B1 system performance tests).

7.3 ADS Performance (BI) Tests The ADS performance tests shall be performed with the 4-in. and 8-in. ADS valves fully open or fully closed in order to simulate a portion of the AP600 plant ADS operation. For example:

• ADS stage 1 operation shall be simulated with the 4-in, globe valve open and the two 8-in.

gate valves closed m:W8@986w. mon:lb-031495 72

i ADS stage 1 and 2 operations shall be simulated with the 4-in. globe valve open and one of two 8-in. gate valves closed

• - ADS stage 1,2, and 3 operations shall be simulated with the 4-in. globe and the two 8-in.

gate valves open U

In addition, three different test facility arrangements shall be used:

Blowdowns with saturated water from the bottom of the steam / water supply tank to the ADS valve / piping ring (with no orifices to simulate the 4-in. gate or 8-in. globe valves) shall be performed to obtain bounding maximum mass flowrates at low fluid quality.

. . Blowdowns with saturated water from the bottom of the steam / water supply tank to the ADS valve / piping ring (with orifices simulating the minimum area of a 4-in. gate or 8-in. globe valve) shall be performed simulating maximum valve resistances through the ADS and at expected flow rates and fluid qualities associated with ADS operation.

'

• Blowdowns with saturated steam from the top of the steam / water supply tank to the ADS valve / piping ring shall be performed with orifices simulating the minimum area of a 4-in. gate or 8-in. globe valve. These test runs shall provide the bounding minimum mass flowrates at

. high fluid quality.

The above described ADS simulations and facility arrangements are incorporated into Table 7-1, which specifies the ADS B1 test matrix. The test matrix has been developed from NOTRUMP predictions of the test facility behavior. The supply tank pressures and A&M valve flow areas have been selected to achieve the mass flow / steam quality conditions shown in Figures 7-1 to 7-4. These conditions are intended to bound or replicate the expected AP600 plant operating conditions as shown. The detailed

intent for each test is listed in Table 7-2.

lhe following major steps are to be incorporated into the test runs using saturated water from the bottom of the steam / water supply tank (test runs B-1 through B-22).

The Edwards and A&M 12-in. gate valves are closed to isolate the steam / water supply tanks from the downstream piping.

• . The A&M 12-in. gate valve is opened to the desired flow area. The distance from the bottom edge of the A&M valve seat ring to the bottom edge of the valve disks (both upstream and downstream) is to be verified using a boroscope.

. Note: The stem position determined above should be recorded during the cold preoperational tests described in Section 7.1 above, so that boroscope inspections with the steam / water supply tank at hot / pressurized conditions are minimized / eliminated.

m:W8@0986w. mon:lb.031495 7-3

• 1he steam / water supply tank shall be filled with ~16 metric tons of water and heated to the desired pressure noted in Table 7-1.

. . The A&M valve shall then be opened to the desired flow area noted in Table 7-1.

. Note: The desired flow area shall be established based on the flow area vs. stem travel data. The actual distance from the bottom inside edge of the valve seat ring to the bottom, outside edge of the .:

valve disks (both upstream and downstream disks) shall be verified using a boroscope. 'Ihis

. verification and the stem position shall be made as part of the cold pre-operational tests described in Section 7.1 above, in order to minimize the need for boroscope inspections when the steam / water

. supply tank is hot and pressurized.

• The 4-in. and two 8-in. ADS valves are to be closed, and the piping from the Edwards valve to the ADS valves is to be heated-up using steam from the supply tank. Periodic draining of the piping will be required to remove condensed steam.

• When the piping has been heated-up, the piping will be drained and depressurized to s I bar

- (14.5 psig) and then the desired ADS valves will be opened to the ADS flowpaths specified in Table 7-1.

• 'lhe test mn is to be initiated by opening the Edwards 12-in. gate valve. This valve is to go to its full open position.

• The test run is to be terminated by closing the 12-in. A&M valve from its partially open position. The test is to be terminated so that the final supply tank water level is 25 percent of span.

• The Edwards 12-in. valve is then to be reclosed to complete isolation of the supply tank.

The test runs using saturated steam from the top of the steam / water supply tank (test runs B-23 through B-26) shall be conducted in a manner similar to the tests performed in the ADS phase A test.

However, the 4-in, and 8-in. ADS valves can be closed to facilitate heatup of the steam supply piping. ,

However, this piping is to be drained and depressurized before the desired ADS valves are opened.

After the ADS valves are fully opened, the test can be initiated using the ENEA steam isolation and

control valves. *{

7.4 Post-Operational Tests ,

On completion' of the performance tests (Section 7.3) the following tests shall be carried out:

• Leakage tests of 12-in. A&M gate valve

. Repeat of valve baseline tests (Section 7.1) on 12-in. Edwards and A&M gate valves
