N DOCKET NO. 50-312 RANCHO SECO NUCLEAR GENERATING STATION LICENSE NO. DPR-54 SPECIAL REPORT NUMBER 88-01, FIRE BARRIERS BREACHED HORE THAN 7 DAYS

Dear Mr. Martin:

The Sacramento Municipal Utility District hereby submits Special Report No. 88-01 in accordance with Rancho Seco Nuclear Generating Station Technical Specifications 3.14.6.2 and 6.9.5.E.

This report provides an updated list of non-functional fire barriers which have not been restored to functional status within seven days.

The District evaluates each non-functional fire barrier against the requirements of Technical Specification 3.14.6 and ensures the proper fire watch is established.

Since the last Special Report (87-26), 29 reportable breaches have been repaired. An additional 46 breaches were added during this period to support j

ongoing modification activities. On January 1, 1988, there were 45 breaches.

The District is expediting the remaining breach repairs to support restart.

Please contact me if you have any questions. Members of your staff with questions requiring additional information or clarification may contact Mr. Kurt Zimmermann at (916) 452-3211, extension 4627.

Sincerely, 8801280017 880113 g
