During a review of abnormal operating proc … During a review of abnormal operating procedure (AOP) 10A, Safe Shutdown-Local Control, by the NRC triennial fire inspection team, it was identified that fire damage to the reactor coolant system (RCS) power-operated relief valve (PORV) and block valve circuits as a result of a fire in the cable spreading room could also result in simultaneous damage to a block valve circuit and spurious actuation of a PORV. While the actions included in abnormal operating procedure (AOP)-10A provide reasonable assurance that positive control of RCS Inventory is maintained, these steps do not ensure that simultaneous failure of the block valve circuit and spurious operation of a PORV will not result in RCS depressurization. Therefore, a postulated fire may potentially remove the ability to fully implement the Safe Shutdown Strategy. Compensatory measures in the form of twice-per-shift fire rounds in the cable spreading room have been implemented.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
