@ME Carolina Power 8 Light Company OCT 32 1992 SERIAL: NLS 288 United States Nuclear Regulatory Commission ATTENTION: Document Control Desk Washington, DC 20555 SHEARON HARRIS NUCLEAR POWER PLANT DOCKET NO. 50-400/LICENSE NO. NPF-63 NUREG-0737, Item II.K.3.17; REPORT ON OUTAGES OF ECCS SYSTEMS Gentlemen:
NUREG-0737, "Post TMI-Requirements," Item II.K.3.17 "Report on Outages of Emergency Core-Cooling Systems Licensee Report and Proposed Technical Specification Changes" dated October 31, 1980, requires licensees and applicants to submit an Emergency Core Cooling System (ECCS) outage history for a five year period.
The attached data represents a summary of the Shearon Harris Nuclear Power Plant (SHNPP) ECCS outage times (component and system). The data covers the five year period commencing with the issuance of the low power operating license on October 24, 1986 and ending October 23, 1991. It includes required maintenance and surveillance testing and was obtained from Equipment Inoperable Records and the Surveillance Test Scheduling System (STSS). The data obtained from STSS for duration is estimated based on average performance time.
Attachment 1 provides the: a) Outage dates and durations (in hours) b) Cause of each outage c) ECC System or components involved d) Corrective actions, as applicable Attachment 2 is a glossary of terms and abbreviations used in Attachment l.
Safety system availability is tracked and reported monthly to the Institute of Nuclear Power Operations (INPO) in accordance with the guidance provided by INPO. Improvements have been accomplished in recent years by scheduling testing and maintenance outages concurrently. Carolina Power & Light Company (CP&L) is committed to ensure the highest safety system availability and performance possible, given the necessary preventive maintenance, corrective maintenance, and required surveillance test:s.
Carolina Power & Light Company has reviewed the availability of ECCS systems and components and concludes that no Technical Specification changes are warranted.
