Planned maintenance activities are being p … Planned maintenance activities are being performed today (November 8, 2008) on the Hatch Nuclear Plant's 1C 4160V Bus (1R22-S003) Frame 5 under work order number 1041640301. The planned work will remove power from 1R24-SO34 and 1R24-SPO60 which will affect the Unit 1 Service Building and Unit 2 Service Building Annex. This will deenergize power to the Primary Operations Support Center (OSC) rendering the OSC non-functional.

This work activity is planned to be performed expeditiously and will be completed within 10 hours. If an emergency were to occur, it is estimated that power can be restored in approximately 1 hour. If an emergency condition occurs that requires activation of the OSC, the Alternate OSC in the Simulator Building will be used in accordance with plant procedure 73EP-EIP-021-0, Alternate Operations Support center (OSC) Activation, until power is restored.</br>This event is reportable per 10CFR50.72(b)(3)(xiii) as described in NUREG-1022, Rev. 1 since this work activity affects the emergency response facility.</br> </br>The licensee notified the NRC Resident Inspector.</br>* * * UPDATE ON 11/8/2008 AT 1614 FROM EDWIN URQUHART TO MARK ABRAQMOVITZ * * *</br>At 1602 EST, power was restored to the OSC Motor Control Center. </br>Notified the R2DO (Widmann).rol Center.
