Mr. J.

Subject:

Docket Nos. 50-361 and 50-362 30-Day Report, Inoperable. Fire Doors San Onofre~ Nuclear Generating Station, Units 2 and 3

Reference:

Letter, H.

B. Ray (SCE) to J.

B.

Martin (NRC),

dated October 18, 1983 In accordance with our referenced letter, this submittal provides the-30-day written report, pursuant to Technical Specification 6.9.1.13.b, for fire-rated assemblies (specifically fire doors) found inoperable during routine surveillances.

Fire doors found inoperable during the October routine surveillances are identified in the Attachment and include:

17 latching mechanism

• failures; 37 closure mechanism failures; and 20 doors blocked open typically for construction, startup or maintenance activities.

As each of these deficiencies was identified, compensator'y fire watches, pursuant to Technical Specification 3.7.9, Action Statement

'a',

were established.

Mi As reported previously, Design Change Packages (DCP's)'are being developed to upgrade door' latches and closure mechanisms into heavier duty hardware and to ensure a constant prassure differential across the access doors in the Radwaste and Control Buildings in order to reduce the door closure problems.

Mr. J. B. Martin tbvember 15, 1983 The administrative deficiencies which have permitted fire doors to be blocked open have been investigated.

.To effect control, fire doors impaired for construction or maintenance activities will be included in the Fire Barrier Removal and Reinstallation Request

-(FBRRR) Procedure to ensure proper compensatory measures are in place prior to any work performance.

As long term corrective action, the installation of utility penetrations adjacent to the 7

-doors for the routing of temporary cables, conduits and/or hoses, 1

to avoid blocking open the fire doors is under consideration.

Results of surveillances conducted during November 1983 will be reported by December 15, 1983.

If you require any additional information, please so advise.
