On April 25, 2013 at 1759 CDT, with Unit 2 in Mode 6 during a refueling outage, power was interrupted to all Unit 2 vent stack radiation monitors as part of a pre-planned activity to connect the radiation monitors to an alternate temporary power supply to support de-energizing the normal power source for preventative maintenance. The connection to the alternate supply was completed and power was restored to the vent stack radiation monitors at 1845 CDT. While the radiation monitors were without power, pre-planned compensatory measures were implemented to monitor vent stack discharge and to minimize activities that posed a potential for release. | On April 25, 2013 at 1759 CDT, with Unit 2 in Mode 6 during a refueling outage, power was interrupted to all Unit 2 vent stack radiation monitors as part of a pre-planned activity to connect the radiation monitors to an alternate temporary power supply to support de-energizing the normal power source for preventative maintenance.
