Event Text
LOSS OF SAFETY FUNCTION 

"At 13:00 [EDT] on Saturday, August 23, 2014, both trains of the Peach Bottom Atomic Power Station (PBAPS) Emergency Service Water (ESW) System were declared inoperable on Unit 2 and Unit 3, due to a pin-hole, through wall piping leak. In accordance with 10CFR 50.72(b)(3)(v), this event is being reported as an event or condition that could have prevented the fulfillment of the safety function of systems that are needed to shut down the reactor and maintain it in a safe shutdown condition, remove residual heat and mitigate the consequences of an accident. 

"At 19:22 [EDT], the station received verbal approval of a Notice of Enforcement Discretion (NOED) request. Simultaneously, the station is preparing an evaluation to support an emergent-relief request.
