On May 28, 2008, at 1730 hours, control roOn May 28, 2008, at 1730 hours, control room operators determined after testing, that the Emergency Service Water (ESW) Division 3 subsystem was inoperable due to a condition that will not allow the subsystem to maintain 'keep-fill' pressure in the event of a loss of offsite power. Technical Specification (TS) Limiting Condition for Operation (LCO) 3.7.2 requires that the High Pressure Core Spray (HPCS) System (a single train safety system) be declared inoperable immediately when the ESW Division 3 Subsystem is inoperable. The plant immediately entered TS LCO 3.5.1 Condition B, HPCS System inoperable. TS LCO 3.5.1, Required Action B.1, verify by administrative means that the Reactor Core Isolation Cooling System is operable within one hour, was completed at 1730 hours. Required Action B.2 requires that the HPCS System be restored to operable status within 14 days. Maintenance/troubleshooting activities are in progress to determine the cause of the ESW Division 3 Subsystem condition.</br>This event is being reported as a condition that could have prevented the safety function of structures or systems required to mitigate the consequences of an accident. The resident inspector has been notified. The resident inspector has been notified.  +
