$ SMUD SACRAMENTO MUNICIPAL UTIUTY DISTRICT E3 62o1 S street, P.o. Box 15830, Sacramento CA 95852-1830,(916) 452 3211 AN ELECT RIC SYSTEM SERVING THE HEART OF CALITOHNIA RJR 86-91 March 4, 1986 J B MARTIN REGIONAL ADMINISTRATOR REGION V 0FFICE OF INSPECTION AND ENFORCEMENT ATTENTION DOCUMENT CONTROL DESK U S NUCLEAR REGULATORY COMMISSION WASHINGTON DC 20555 D0CKET NO. 50-312 LICENSE N0. DPR-54 SPECIAL REPORT NUMBER 86-03, FIRE BARRIERS The Sacramento Municipal Utility District hereby submits Special Report 86-03 in accordance with Rancho Seco Nuclear Generating Station Technical Specifi-cations, Section 3.14.6.2 and 6.9.5E.
This report provides an updated list (attached) of non-functional fire barriers reported in our January 30, 1986 Special Report 86-02, and identifies any non-functional fire barriers detec-ted or created since that report which were not restored to functional status within seven (7) days.
The District has evaluated each non-functional fire barrier against the re-quirements of Technical Specification 3.14.6 and has verified that the proper fire watch has been established.
The District is currently developing the capability to include in the list of breac. Sed barriers the plan and schedule for restoring each fire barrier penetration to its functional status.
It is intended that the additional in-formation will be used in the establishment of a programmatic plan which will significantly reduce the number of fire barriers being non-functional for a period greater than seven (7) days. Tne upgraded report is expected to be available by April 15, 1986.
An updated status for each penetration program discipline is given 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 comments column of the attached list.
Breaches identified as surveillance ite.is remain scheduled for a March 31, 1986, completion.
2.
Mechanical Penetrations - The expansien 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 ongoing plant work and surveillance testing recently completed.
