SUBJECT:
Docket Nos. 50-317 and 50-318; LER 81-08 (U-1)
Dear Mr. Grier:
This letter is to confinn our verbal notification of your Mr. Ralph Architzel of the inoperability on February 3,1981 of a number of fire hose stations in the Auxiliary Building and in the Unit 2 Con-tainment Building without backup hose stations as required by T.S.
3.7.11.4.
At 1800 on February 3,1981, the Shift Supervisor discovered that the Unit 2 Containment Building fire hose stations and a number of the Auxiliary Building fire hose stations had been isolated since about 0800 without the required routing of backup fire hoses. Backup fire hoses were rigged for all affected hose stations by 2150 on February 3.
Fire watches had been stationed at various locations in the Auxili-ary Buildi 1 and in the Unit 2 Containment Building during this event.
A complete description of the cause and corrective action will be in-cluded in the follow-up report.
