On 10/4/2010, at 2200 CDT, Wolf Creek Gene … On 10/4/2010, at 2200 CDT, Wolf Creek Generating Station (WCGS) commenced a plant shutdown due to inoperability of the 'A' Train of Essential Service Water (ESW). On 10/2/2010, at 0642 CDT, 'A' Train ESW was declared inoperable due to indications of a leak on the buried ESW supply line. Technical Specification 3.7.8, Essential Service Water (ESW) System, Condition A, allows 72 hours to restore an inoperable ESW train. Location of the leak was identified using Ground Penetrating Radar and confirmed by excavation. Work is underway to evaluate and repair the leak. Since this work is expected to take longer than the allowed completion time (72 hours), it was decided to commence plant shutdown prior to expiration of the allowed 72 hours (10/5/2010 at 0642 CDT). Plant shutdown is required by Technical Specification 3.7.8, Condition B. Current plan is for the plant to be in Mode 3 (Hot Standby) by 0700 CDT on 10/5/2010. Plant cool down to Mode 5 will commence following shutdown and continue until such time as the leak has been repaired and the train restored to operable or until Mode 5 is reached.</br>The leak has been quantified as approximately 11.5 gpm. </br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
