FitzPatrick Nuclear Power Plant Docket No. 50-333 NUREG-0737 Item II.K.3.3 Safety and Relief Valve Failures and Challenges
Dear Sir:
NUREG-0737 Item II.K.3.3 requires that challenges to safety and relief valves (SRVs) be reported on an annual basis. to this letter provides a report of challenges occurring between January 1, 1983 and December 31, 1983. provides a report of challenges occurring between January 1, 1982 and December 31, 1982.
This report was inadvertently not transmitted previously.
If you have any further questions, please do not hesitate to contact us.
Very truly yours, g

- Subsequent test at Wyle Laboratory did not reveal any problem.
)9/03/83 02-RV-71H None Yes
- Valve serial No. 1053
- Setpoint 1140 (
1%) psig
- Valve solenoid failed to operate from remote SRV panel during surveillance test due to a ground fault in the DC control circuit.
Valve, however, was fully operable from the control room, from ADS logic circuits and with respect to reactor pressure demand.
Operated normally from remote SRV panel following correction of ground fault.

- Failure Remarks 10/18/82 02-RV-71D None Yes
- Valve serial No 1080
- Set point 1140 (i 1%) psig
- Test at Wyle Laboratory revealed lift pressure of 1204 psig.
It was found that there was gross pilot leakage and pilot disc and seat were steam cut.
Valve was refurbished and retested with satisfactory results with a setpoint of 1105 (f l% ) psig.
