METHOD OF TEST
2.0 DESCRIPTION
OF TEST SPECIMEN
- 1) Purge Containment Isolation Valve Assembly, with Vespel SP-1 (DuPont Trademark) polyimide seat ring.
18 inch ANSI 150 Class Valdisk, similar to Serial No.
34753/2-48.
- 2) Two additional seat rings, identical to the one installed in the valve assembly.
These two seat rings were subjected to accelerated thermal aging and radiation exposure to simulate 2.63 and 4 years normal life (see sections 3.4.1 and 3.4.3).
The additional seat rings were also to be subjected to the accident radiation dosage (see section 3.4.6).
This was not accomplished since the rings were lost in transit during the Normal Dosage Radiation Exposure.
The purpose for including these seat rings in the test was to provide back-up seats with which to continue the test in the event the original seat ring failed during testing.
Prior to the initiation of the test program the valve was functionally tested, by Valtek personnel, in
\\
accordance with the following:
3.0 METHOD OF TEST Testing was accomplished in accordance with the following procedures.
NOTE: The Margin of Safety requirements, specified by IEEE-323-1974, were taken into consideration in American Environments Qualification Test Procedure Number STR-33186-1, Revision A.

Functional Test 3.2 TEST SET-UP The valve assembly was installed in the Test Fixture and connected as shown in Figure 1, Appendix A. Testing was performed on the valve described in paragraph 2.0.
All test set ups simulated typical in-service installation and orientation.
All testing outlined herein was performed with the valve assembly mounted in the vertical position.
3.3 PRE AND POST QUALIFICATION TESTS 3.3.1 Visual Inspections Prior to and following each test outlined herein, the valve was visually inspected in order to determine any physical damage which may have occurred.
3.3.2 Functional Tests.
The specimen was functionally tested in order to determine its' ability to maintain seat leak within the specified limit.
The valve was installed in the functional set-up shown in Figure 1.
The valve was energized to the open position utilizing a supply voltage of 130 volts (DC) and an actuator pneumatic pressure of 70 psig.
After opening the valve the DC voltage was reduced to 0 in
~
order to close the valve.
Seat leakage was measured as outlined below:
l
. Step 1) The containment (inlet) port of the valve was pressurized to 54 psig'r(48.4 + 10%) utilizing l
air, filtered to 10 mic ons, as a test media.

METHOD OF TEST 3.3 PRE AND POST QUALIFICATION T'ESTS (Continued) 3.3.2 Functional Tests.(Continued)
Step 2) After pressurization, the system was isolated by closing a hand valve, located upstream from the valve.
Step 3) Following a, leakage, as evidenced by a decay in five (5) minute stabilization period, any inlet pressure was noted.
Step'4) In the event of pressure decay in Step 3, the leakage rate was measured utilizing a flowmeter located downstream from the valve.
During portions of the test when large leakage rates were noted the leakage was measured utilizing a graduated cylinder / water bubble set-up (See Figure 1, Appendix A).
The maximum allowable leakage was as follows.
New Valve: 34 Std. cc/ min with air at 54 psig End of Life: 1) 1330 Std. cc/ min with air at 54 psig, or
- 2) 4.5 cc/ min water. (LOCA testing only)
(
During the LOCA test the seat leakage test was performed as follows:
During the performance of the initial transient of LOCA testing the specimen was visually monitored for gross leakage.
During the remaining portions of LOCA testing all fluid condensate exiting from the specimen outlet port was collected and the leakage rate (if any) measured and noted.
3.4 QUALIFICATION TEST METHODS 3.4.1 Accelerated Thermal Aging The valve assembly was installed in an eqrico.Tental chamber capable of simulating the required elevated thermal condition.
