DPR-54 SPECIAL REPORT NUMBER 86-20, FIRE BARRIERS BREACHED MORE THAN 7 DAYS The Sacramento Municipal Utility District hereby submits Special Report No. 86-20 in accordance with Rancho Seco Nuclear Generating Station Technical Specifications, Section 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 (7) days. The District has evaluated each non-functional fire barrier against the requirements of Technical Specification 3.14.6 and has verified that the proper fire watch has been established. Those breaches listed with "ENG EVALUATION" or "NEW ECN" in the

     " PLAN TO REPAIR" column, require additional design or engineering work. The forecasted completion dates provided for these breaches reflect only the completion of the engineering work.

Once the engineering work has been completed, the implementation of the design will be scheduled. Since the last Special Report (86-19), 20 breaches have been repaired. Of those completed, 9 were completed behind schedule. Currently, there are 71 breaches still open and past the forecasted closo date. An additional 18 breaches were added during this period. Progress has slowed in oosling breaches due to the nature of the remaining problems and continued heavy activity in support of the restart outage. 0610200470 061017 PDR ADOCK 05000312 S PDR
