DPR-54 SPECI A'. REPORT NUMBER 86-04, FIRE BARRIERS The Sacramento Municipal Utility District hereby submits Special Report 86-04 in accordance with Rancho Seco Nuclear Generating Station Technical Specifica-tions, Section 3.14.6.2 and 6.9.5E.
This report provides an updated list (attached) of non-functional fire barriers reported in our March 4,1986 Special Report 86-03, and identifies any non-functional fire barriers detected or created since that report which were not restored to functional status within seven (7) days.
The District has evaluwd'aach non-functional fire barrier against the require-ments of Technical Specification 3.14.6 and has verified that the proper fire watch has been established.
As stated in the March 4,1986 report, the District is developing the canabil-ity to include in this report of breached barriers the plan and schedule for restoring each fire barrier penetration to its functional status.
It is intended that the additional inform'.thn will be used in the establishment of a programnatic plan which will significantly reduce the number of fire barriers being non-functional for a period greater than seven (7) days. The upgraded report is expected to be available by April 15, 1986.
An updated status for each penetration program discipline is niven in the following paragraphs:
1.
Electrical Penetrations - The fire tests for the conduit penetration seals have been completed and the results are being incorporated into the District's calculations.
The incorporation of the fire test results into the calculations is expected to result in the approval of all of the con-duit seals that are designated by "C" in the consnents column of the attached list. Breaches identified as surveillance items which were identified in Special Report 85-14 remain scheduled for a March 31, 1986 completion.
2.
Mechanical Penetrations - The expansion joint remains as the only item from the originally identified scope of work.
The other mechanical pene-trations listed in the attachment have resulted from ongoina plant work and surveillance testing recently completed.
