UNITEDSTATES NUCLEAR REGUI ATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION INTRODUCTION By letters dated April 5, 1985 and November 13, 1985, Florida Power'nd Light Company requested approval to update the requirements for system pressure tests to the 1980 Edition through Winter 1981 Addenda of Section XI of the ASME Boiler and Pressure Vessel
- Code, and to extend the 10-year inspection interval for the St. Lucie Plant, Unit No. 1, because of a continuous outage of over 1 year for repair of the core support barrel.
E EVALUATION The St. Lucie Plant, Unit Nos.
1 and 2 are now being examined in accordance with the requirements of 1974 Edition through Summer 1975 addenda of Section XI of the ASHE Code.
The Regulations, 10 CFR 50.55a(g)(4)(iv), allow the use of requirements in later editions and addenda of Section XI that have been approved by the Commission and incorporated in paragraph (b) of 10 CFR 50.55a.
Portions of editions and addenda may be used provided that all related requirements of the respective editions or addenda a'e met.
Paragraph (b) presently cites the 1980 Edition through Winter 1981 Addenda as the l,atest approved edition and addenda.
Section XI of the ASME Code, IWA-2400(c) allows the extension of the inspection interval for power units that are out of ser vice continuously for 6 months or more.
The inspection interval during which the outage occurs may be extended for a period equivalent to the outage.
Because of extensive core barrel repairs, the St. Lucie Unit 1 was. continuously out of service from February 26, 1983 to April 16, 1984.
The current inspection interval will end on December 21, 1986.
The licensee has requested approval of an extension of the 10-year inspection interval completion to February 11, 1988.
CONCLUSION Based on the above evaluation, the request for the update of pressure test
.requirements to the later'dition of the Code is within the provisions of the Regulations, and therefore, is approved.
Further, the staff has also concluded that the request for extending the completion date for the first 10-year inspection interval for Unit 1 is within the requirements of the Regulations and, therefore, is approved.
Approval of the update of the pressure test requirements and the extension of the 10-year inspection interval is authorized. by law, and will not endanger life or property, or the common defense and security, and is otherwise in the public interest.
