As a result of the power loss, the 1H Emergency Diesel Generator and the 2J Emergency Diesel Generator automatically started as designed and restored power to the associated emergency bus. During this event, the Unit 2 'A' Charging Pump, 2-CH-P-1A, automatically started as designed due to the loss of power event. "The valid actuation of these ESF [Engineered Safety Feature] components due to the loss of electrical power is reportable per 10 CFR 50.72 (b)(3)(iv)(A). "The Unit 1 'H' Emergency Bus off-site power source was restored to service and the 1H Emergency Diesel Generator was secured and returned to automatic. The Unit 1 Action Statement of Technical Specification 3.8.1 was cleared at 2115 hours on 5-15-2014. The Unit 2 'J' Emergency Bus power feed continues to be from the 2J Emergency Diesel Generator and this line-up will remain until the off-site power source can be restored to operable status. The Unit 2 'A' Charging Pump has been secured and returned to automatic. "Both Units are in a stable condition. An investigation is underway to determine the cause of the 34.5 kV Bus 5 loss of power." Power was returned to the Unit 1 'H' Emergency Bus via the Unit 1 'B' Reserve Station Service Transformer. The licensee will be notifying local Louisa County officials and has notified the NRC Resident Inspector.
