llACKGROUND On October 5,1992 the Fire Detection for the Spent Fuel Area was disabled. The smoke and tiame detection in the Spent Fuel Area was disabled to permit work activities to be conducted (welding, cutting and grinding operations) during the modification work under Facility Change Request (FCR) 88-0081. This FCR will accomplish the installation of a new spent fuel c ane.
As specified by Technical Specification 3.3.3.7, Action Statement b, a special report must be issued to i
the Commission pursuant to Technical Specification 6.9.2 if the fire detection system is not restored j
to an OPERABLE status witLin 14 days.

EFFECT ON UNIT OPERATION 1
i On October 5,1992 with both Unit 1 and 2 a: MODE l', the smoke and flame detection system for the Spent Fuel Area was disabled in accordance with our temporary alteration process. The smoke and flame detection in the Spent Fuel Area is listed in Technical Specification 3.3.3.7. Action Statement b, to this Technical Specification requires an hourly fire watch patrol be established to inspect the fire zone. In addition to the hourly fire watch patrol, a continuous tire watch is required j
by Calvert Cliff procedures during welding / cutting / grinding operations in the room. Based on the fact that adequate controls are in place to prevent, detect, and mitigate the effects of potential fires in the Spent Fuel Area, the disabling of the smoke and llame detection has no effect on Unit operation.

FCR 88-0081 is scheduled to be completed by Decembe-1992 and the appropriate actions will c ntinue in accordance with Technical Specification 3.3.3.7 and procedural requirements until the r
fire detection equipment in the area is restored to an operable status.
