Finding

Title

LICENSEE-IDENTIFIED Violation

Description

Technical Requirements Manual (TRM) section 6.2.1 requires that fire detection instrumentation for each fire detection zone shall be operable and if the required detection system is inoperable an hourly fire watch must be established. Contrary to this, on February 9, 2011 the licensee identified that fire detection instrumentation for fire zone 2-12 had been left in the non-audible alarm for the main control room on the fire computer when the limiting condition for operations was cleared on December 8, 2010 when zone was returned to operable status. The control room supervisor on February 9, 2011, discovered this condition when entering a fire-limiting condition for operation for the division 1 diesel generator room to allow welding. The licensee determined that it had been in non-audible status from December 8, 2010, through February 9, 2011. This issue was documented in the licensees corrective action program in condition report CR-GGN-2011-00851. The senior reactor analyst from region IV performed a bounding evaluation of the change in risk caused by this condition. According to the Grand Gulf Updated Final Safety Analysis Report, Fire Zone 2-12 only contains Division I equipment. A fire that consumed the equipment in the area could not result in a loss of offsite power or other unplanned transient. Given the ignition frequency of the area, the 60-day exposure period, and the conditional core damage probability with the loss of the Division I emergency diesel generator, the analyst calculated that the change in risk was significantly less than 1E-6. Therefore, this finding was of very low safety significance (Green).
