| event text = At 0624 EDT on 04/02/2012 the control room was notified by a plant operator that there was a fire in the plant vital battery room area on Unit 2. The fire was located in the lower compartment of inverter 2KUI. This equipment supplies power to 120V AC non-safety related components. The fire brigade captain was dispatched along with the site fire brigade. When the fire brigade captain arrived the operator was staged near the inverter with a CO2 [carbon dioxide] fire extinguisher. The fire brigade captain instructed the NLO [non-licensed operator] to extinguish the fire with the extinguisher. The fire was immediately extinguished once the CO2 was applied from the extinguisher. At 0633 EDT the fire brigade captain reported to the control room that the fire was extinguished. Upon further investigation it appears that transformer in the lower compartment of the inverter had caught fire. The fire was confined to the lower compartment of the inverter and did not affect any other components in the area. Due to the loss of the inverter the loads automatically swapped to the alternate AC source as designed and no indications or equipment were lost due to the loss of the inverter. | | event text = At 0624 EDT on 04/02/2012 the control room was notified by a plant operator that there was a fire in the plant vital battery room area on Unit 2.

At the time of this event Unit 1 was at 100% power and Unit 2 was shutdown in Mode 6 with reactor coolant system drained to 8% level with 2B Residual Heat Removal pump supplying core cooling. There was no impact to either unit as a result of this event. All equipment required to maintain core cooling, AC and DC power, and reactor coolant inventory on Unit 2 was maintained during this event. | At the time of this event Unit 1 was at 100% power and Unit 2 was shutdown in Mode 6 with reactor coolant system drained to 8% level with 2B Residual Heat Removal pump supplying core cooling.
