On Wednesday, July 17, 2013 at 1054 hours … On Wednesday, July 17, 2013 at 1054 hours EDT, with the reactor at 100% core thermal power (CTP) the Pilgrim Nuclear Power Station (PNPS) entered a 24-hour shutdown Limiting Condition for Operation (LCO) for Salt Service Water (SSW) inlet temperature exceeding the Technical Specification (TS) limit in TS 3.5.B.4. The LCO was subsequently exited at 1625 hours when the temperature of SSW trended to below the TS limit.</br>Under certain accident conditions the SSW system is required to provide cooling water to the Reactor Building Closed Cooling Water (RBCCW) system heat exchanger. When the inlet temperature to this supplied load exceeds the 75 (degrees) F limit established in the TS, the SSW system is declared inoperable until the temperature trends below this value. This condition existed for approximately 5-1/2 hours and the SSW system was declared operable and the LCO exited. A maximum temperature of 75.5 (degrees) F was recorded during this period.</br>At 1230 hours a power reduction was conducted to improve secondary plant parameters and Rx power is currently 85%. </br>The SSW temperature is being closely monitored and trended on a continuous basis.</br>This event has no impact on the health and safety of the public.</br>The licensee has notified the NRC Senior Resident Inspector."
