May 12,1981 Mr. Boyce H. Grier. Director Docket No. $ % 317 Office of Irispection & Enforcement License No. DPR-33 U. 5. Nuclear Regulatory Commission Region 1 631 Park Avenue King of Prussia, Pennsylvania 19406 5UBJECT: Docket No. 30-317/3 % 318: LER 81-31 (U-1)
Deer Mr. Griert This report is to confirm our verbal notification to your \1r. Ralph E. Architzel as required by T.S. 6.9.1.8.6 (Prompt Notification with Written Follow.up) of an inoperable fire protection hose station which was required to be in servlee according to T.S. 3.7.11.'4 At 1945 with Unit I and Unit 2 at f ull power. it was dlscovered that less than the required number of hooe stations were operable on the -10 f oot elevation in the Auxiliary Building. At approximately 1310, portions of the Auxiliary Building fire protection Detailed plans system were placed out of service to f acilitate tying in new sprinkler systemt,.
were prepared by the Fire Protection Inspector to ensure that all technical specification required hooe stations remained operable. However, due to an error in instructions provided to the operators and the operators' unf amillarity with new fire systema leolation valves, both -10 f oot hose stations (H5 f-)l0 - 27 and HS f-)l0 A M were isolated and neither hoea station was provided with a water Supply f rom an nperable home 5t'atinn as required. Upon discovery..both hose stations were immediately returned to.se.rvice and were verified operable at 2010. During this event, because of maintenance being performed in the -10 foot elevation, a continuous fire watch with an additional fire extinguisher had been provided even though one was not required.
A complete description of the cause and corrective action will be included in the follow-up report.
Very truly yours, 8I %
