Document Control Desk United States Nuclear Regulatory Commission Washington, DC 20555 SHEARON HARRIS NUCLEAR POWER PLANT DOCKET NO. 50-400 LICENSE NO. NPF-63 Gentlemen:
Pursuant to Technical Specification 6.9.1.2c for the Shearon Harris Nuclear Power Plant, Unit No. 1, Carolina Power
& Light Company herewith submits a report of challenges to the pressurizer power-operated relief valves (PORVs) and safety valves which occurred in 1986.
Technical Specification 6.9.1.2c does not require an Annual Report for 1986 since initial criticality was not achieved until January 3,
1987.
- However, the attached information is being provided in lieu of submitting the data in the Annual Report for 1987.

CHALLENGES TO THE PORV's AND SAFETY VALVES A.
On December 3,
- 1986, a low-temperature, over-pressure event occurred while conducting filland venting operations of the Reactor Coolant System.
The cause of the event was due to personnel error aggravated by a procedural deficiency and equipment problems.
The pressurizer Power Operated Relief Valve lifted at its appropriate setpoint to control Reactor Coolant System pressure.
(Special Report dated January 2,
1987)
B.
On December 8,
- 1986, a low-temperature, over-pressure event occurred while the Reactor Coolant System was being operated under solid water conditions.
The cause of the event was due to a failed capacitor in the power supply card for the pressure transmitter for.
the letdown system's pressure control valve (PCV-145).
The pressurizer Power Operated Relief Valve lifted at its appropriate setpoint to control Reactor Coolant System pressure.
(Special Report dated January 2,
1987)
C.
On December 29,
- 1986, a over-pressure event occurred during preparation for Power Ascension Test "Rod Drop Test No Flow Condition".
The cause of the event was due to a pressure transient caused by starting an idle Reactor Coolant Pump.
The pressurizer Power Operated Relief Valve lifted at its appropriate setpoint to control Reactor Coolant System pressure.
