Dear Sir:

Subject:

Docket Nos. 50-361 and 50-362 Follow-up Report, Inoperable Fire Doors:- July 1984 San _0nofre Nuclear Generating Station, Units 2'and 3

Reference:

Letter, J. G. Haynes (SCE) to J. B. Martin (NRC),

dated July 19, 1984 In accordance with our referenced letter, this submittal provides the follow-up report of fire-rated assemblies (specifically fire doors) found inoperable during routine surveillances in July 1984.

Fire doors found inoperable during the July routine surveillances are identified in the Attachment and include: 5 latching mechanism failures; 10 closure mechanism failures; and 7 doors blocked open typically for construction or maintenance activities. As each of these deficiencies was identified, compensatory fire watches, pursuant to Technical Specification 3.7.9, Action Statement 'a', were established.

We are continuing the corrective actions to upgrade door latches and closure mechanisms. A disciplinary action policy was implemented August 15, 1984, by Station Management, in order to eliminate occurrences of blocked open fire

. doors without the-required Fire Barrier Removal and Reinstallation Request.

This monthly follow-up report and those sent previously ' provide updated information associated with an or. going condition initially reported in 1983.

The follow up report covering inoperable fire doors identified in August 1984 will be submitted by September 20, 1984.
