Dear Mr. Tucker:
RDiggs ASLAB We have completed our review of the Oconee Nuclear Station Standby Shutdown Facility (SSF) described in your letters dated March 28, 1980, February 16 and March 31, 1981, April 13, September 20 and December 23, 1982. The SSF design was to resgive the safe shutdown requirementsvforJ fire protection (Appendix R to 10 CFR 50, Sections III.G.3 and ILL),
the turbine building flooding issue and physical security requirements.
Our Safety Evaluation (SE) is enclosed.
- .,,*'find your SSF design meets the appropriate requirements with the exception of process monitoring instruments fo rjsource range flux moniltoring and steam generator pressure indication. It is our under standing that Duke 41 iWjer Company desires to appeal this staff require ment on the McGuire, Unit No. 2 and Oconee dockets. We believe that a uniform approach should be taken for all of your units. An appeal meeting for all units, as requested by your March 31, 1983 letter on the McGuire docket will be scheduled in the near future.
While the exception noted above is being resolved, we request that your staff continue their work on the Technical Specifications needed to insure th operability of the SSF components agrees with fire,.flooding and security assumptions used in the design. We request such Technical Specifications be proposed about 90 days before the final acceptance of the SSF for Oconee, Unit No. 1.
Our interpretation of Appendix R to 10 CFR 50 is that all necessary repairs will be made and cold shutdown achieved in a 72-hour period. Your previous commitment is.
to be prepared to make all necessary repairs for cold shutdown and depressurization. We acknowledge that your commitment was submitted prior to issuance of Appendix R. In recent discussions with Mr. R. Gill of your sitaff, we have learned that Duke Power Company if willing to review the previous commitment on the 72-hour requirement of Appendix R,Section III.L.5 and modify their position or request an exemption from this specific regulation. A mutually agreed upon schedule for this review and submittal of the above res y1ts has been determined to be congruent with the requested Technical Specifications.
