Page 1 November 23, 1987 1.01 SCOPE-This test plan describes the requirements, procedures, and acceptance criteria for thermal endurance testing of ASCO NP 8323 i'
A20E solenoid valves for use as MSIV pilot valves at the Perry Nuclear Power Plant'(PNPP). This environmental test is required per reference 3.1, page 4, item 1.
~
2.0 PURPOSE The purpose of this program is to demonstrate that the solenoid valves vill perform their safety function at a variety of elevated temperatures for a specific length of time in a corinuously ener-gized state. The ASCO pilot valve's safety function is to vent air pressure and close'off supply air from the two-way and four-vay Norgren air control valves which causes the 20-inch air cylinder to extend and.thus close the MSIV.

9' Task 3, solenoid valve Page 2 November 23, 1987 The valves shall be supplied by The Cleveland Electric Illuminating Company (CEI) complete with pipe fittings installed in the solenoid housing conduit connection and a conduit seal of Bisco sealant. The pipe fittings and conduit seal shall be representative of the valves installed on the MSIVs at PNPP.
l l
4.2 Test Specimen Marking and Labeling l
At receipt inspection, each specimen vill be labeled with an aluminum or stainless steel tag indicating specimen number. The test lab shall also keep records of the valve serial number versus specimen number.
4.3 Air Supply The compressed air used for this testing shall be clean, dry, and free of hydrocarbons as follows: maximum particle size, 40 micron; dev point,-40 degrees Fahrenheit: and hydrocarbon content, less than 1 parts per million. A 50 micron filter shall be installed up-stream of the test specimens. The compressed air shall be sampled O
for dev point and hydrocarbons prior to testing.
4.4 Power Supply The specimens shall be supplied with 120 + 5 - 0 VAC uninterruptable power.
4.5 Instrumentation All test equipment and instrumentation to be used in the performance of this test program must be calibrated in accordance with the test facility!s OA program vhich conform.s to, ANSI N45.2,.10CFR50/ Appendix B, 10CFR21, and Military Standard MIL-C-45662A. Standards used in performing all calibrations shall be traceable to the National Bureau of Standards.

5.0 ' ACCEPTANCE CRITERIA The valves shall operate upon demand without sticking or binding.
When de-energized, the valves shall vent'the 27-cubic-inch air tank from 90 to 30 psig in 2.0 seconds or less. Otherwise, the data collected vill be analyzed by CEI personnel in accordance with the requirement for the MSIV to fast close within 5 seconds.
1 6.0 TEST PROGRAM 6.1 Test Sequence Testing shall be conducted in the following sequence:
Baseline Tests Thermal Endurance Test Post-thermal Test Disassembly and Inspection 6.2 Baseline Tests 6.2.1 Visual Inspection The valves shall be visually inspected and photographed. Any dan ge shall be noted and reported to the CEI representative.
Verify specimens are properly tagged.
6.2.2 Punctional Tests Configure the specimens as shown in Figures 1, 2, and 3, except do not heat the oven. Clean and blow out all air system components prior to test to reduce the risk of contam-ination entering the specimens. Consult Appendix I for installation requirements. Energize both solenoid coils for each specimen, allowing the air tanks to pressurize to 90 to 100 psig. Measure the voltage, in-rush current, and the steady-state current for each solenoid. Allow the specimens to remain energized four hours in order to stabilize their temperatures. Record the specimen and ambient temperatures (Figure 2) hourly. Measure leakage at the vent in accordance with paragraph 6.2.2.1.
De-energize both solenoids together and plot the tank's pressure decay curve versus solenoid switch signal. The tank should be exhausted in 2 to 4 seconds. Time shall be measured to within 0.05 seconds and pressure shall be accurate to 1 3 psi.

MSIV EQ Validation Task 3, Solenoid Valve Page 4 November 23, 1987 Immediately following the initial de-energization, repeat the above process twice in the following sequence:
1.
Energize both solenoids. Measure voltage,.in-rush current, and steady-state current for each solenoid.
2.
Perform leakage measurement at vent per paragraph 6.2.2.1.
3.
At 30 minutes after energization (step 1),
de-energize both solenoids. Plot pressure decay vetsus solenoid switch signal.
If a specimen exhibits leakage greater than I cc per minute, that specimen must be repaired or replaced and the baseline test repeated.
6.2.2.1 Leakage Measurement Leakage measurements are performed as an indicator of specimen degradation.
Leakage measurements shall be performed using an inverted graduated' cylinder as shown in Figure 4.
Leakage shall be measured in ml per minute (cc/ min) of air and shall be of five-minute duration. Leakage measurements are for information only; therefore, calibrated equipment for leakage measurements is not required.
6.3 Thermal Endurance Test The six test specimens shall be tested in three groups of two specimens each per Table 1.
Each set of two specimens vill be placed in a separate oven. The oven temperature vill be maintained continuously for 92 days.
Specimen and oven temperatures (Figure 2) shall be recorded hourly. The air pressurt to the specimens shall be maintained at 90 to 100 psig during.the entire 92-day test. The solenoids vill remain energized at 120 4 5 - 0 VAC during the entire 92-day test except for de-energization during cycle tests. The odd-numbered specimens will be cycled (de-energized / energized) every 30 days to simulate the monthly surveillance tests being conducted at PNPP. Specimen 4 vill be cycled (de-energized / energized) at 42 days and once every seven days thereafter.
Specimens 2 and 6 vill not be cycled (de-energized / energized) until after the 92nd day.
O
Task 3, Solenoid Valve Page 5 November 23, 1987 Air tank pressure decay plots vill be generated for each de-energization as described in paragraph 6.2.2.
Perform a leakage test per paragraph 6.2.2.1 on each specimen each working day (Monday through Friday) and after each de-energization/energization cycle. At the end of the 92 days, notify CEI for approval to proceed to paragraph 6.4, Post-thermal Functional Test.
If a specimen fails to operate upon demand or otherwise exhibits anomalous behavior, contact the CEI representative for disposition.
6.4 Post-thermal Functional Test At "he conclusion of the testing specified in paragraph 6.3, turn off the ovens, open the oven doors, allow the ovens to cool to room ambient conditions, and repeat the baseline tests specified in paragraph 6.2.
6.5 Test Documentation A test log and data sheets shall be maintained to provide a complete
,_(')
history of testing.
Each log sheet and data sheet shall be identi-fled by the project number and shall be signed and dated by the person making the measurements.
Interim test results vill be provided to CEI biveekly. CEI must approve the data sheets prior to testing.
A final report vill be issued providing a complete description of the requirements, procedures. and results associated with the test program.
7.0 POST-TEST INSPECTION At the conclusion of testing, the test specimens vill be disassembled, inspected, and photographed. In addition to overall specimen photos, closeup photos of the EPDM discs and seals and their mating metal parts will be made. The use of oil, lubricant, or any potential contaminant is prohibited during the disassembly and inspection. All personnel handling the valve parts shall year clean rubber gloves. Individual valve parts vill be labeled and stored in plastic bags. All specimens are to be returned to CEI for possible further chemical and physical analysis.
8.0 OUALITY ASSURANCE The test program vill be conducted in accordance with the test facility's OA program which shall meet the requirements of ANSI N45.2, 10CFR50/ Appendix B, and 10CFR21.
