B. Martin, Regional Administrator
Dear Sir:
Subject:
Docket Nos. 50-361 and 50-362 Follow-up Report, Inoperable Fire Doors - October 1984 San Onofre Nuclear Generating Station, Units 2 and 3
Reference:
Letter, J. G. Haynes (SCE) to J. B. Martin (NRC),
dated October 15, 1984 In accordance with our referenced letter, this submittal provides the
'ollow-up report of fire-rated assemblies (specifically fire doors) found
- 9 operable during routine surveillances in October 1984.
Fire doors found inoperable during.the October routine surveillances are identified in the Attachment and include: 4 latching mechanism failures; 6 closure mechanism failures; and 5 doors blocked open typically for construction or maintenance activities. An investigation was conducted to determine the person or persons responsible for the blocked open fire doors, however, results were inconclusive. 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 Reinsta11ation Request.
This monthly follow-up report and those sent previously provide updated information associated with an ongoing condition initially reported in 1983. The follow-up report covering inoperable fire doors identified in November 1984 will be submitted by December 20, 1984.
