January 2, 1988 GCA 87-912 U. S. Nuclear Regulatory Commission Attn: J. B. Martin, Regional Administrator Region V, Office of Inspection and Enforcement 1450 Maria Lane, Suite 210 Walnut Creek, CA 94596 DOCKET NO. 50-312 RANCHO SECO NUCLEAR GENERATING STATION LICENSE NO. DPR-54 i FIRE PROTECTION SYSTEM ENHANCEMENT PLAN

Dear Mr. Martin:

I In accordance with commitments aride in LER 87-29, and the exit meeting with the Commission on November 19, 1987, the enclosed documents detail the District's efforts to ensure fire protection and detection systems meet NFPA requirements.

District report ERPT M-0049 evaluated the current fire protection program for compliance with NFPA 12, 13, 14 (except containment),

15, 20, 24, and 72D. An evaluation of the manual firefighting capabilities in containment is currently underway and will be completed prior to restart. One condition involving testing of unsupervised circuits, as reported in LER 87-29, was identified as a violation of Technical Specifications. Compensatory measures were implemented and modifications installed and tested to correct this deficiency. None of the identified conditions degraded the station's ability to achieve and maintain safe shutdown. The deviations from the NFPA code and options for corrective actions to eliminate these deviations are identified in Attachment I, Table 3-1 from ERPT M-0049. This table also includes modification options for the fire detection and alarm systems. Attachment II contains a detailed evaluation of the proposed alarm system modifications. The forecast completion dates in Table 3-1 are tentative; a firm date for each item will be discussed with the NRC in the first quarter of 1988, when the Long Range Schedule Process is finalized.

~J.-B. Martin away 2, M88 GCA 87-912 Acceptance testing of the fire pumps as required to provide baseline data for future testing is scheduled for completion.by May 31, 1988. This satisfies the District's commitment made in our letter dated December 15, 1987, "Resolution of Fire Pump Open Items."

In summary, - the ' above evaluations verified the adequacy of the current fire- protection systems to ensure safe shutdown capability is maintained. Additionally, in order to improve reliability of the systems and meet applicable NFPA requirements, modifications have been identified and scheduled through the Long Range Schedule Process.

Please contact me if you have any questions. Members of your staff requiring further information or clarification may contact Steve Crunk or Dave Swank of my Licensing Staff at extension 4913.
