| event text = Explosion occurred in a non-safety related transformer at 1908 EST 0n 01/13/04. The transformer became deenergized as a result of the explosion. Licensee declared an Unusual Event at 1921 EST on 01/13/04 due to an explosion resulting in visible damage to a non-safety related transformer in the Turbine Enclosure building. There was no fire or injured personnel, and the site did not require any off site assistance. The transformer explosion resulted in the loss of power to some 480 VAC non-safety related loads (most significant was a non-safeguard DC battery charger). The explosion has not severely impacted Unit 1 operations. The transformer has been inspected, and it appears that the explosion was internal to the transformer and due to an electrical malfunction. Security personnel conducted thorough walk downs of all areas and had no concerns. | | event text = Explosion occurred in a non-safety related transformer at 1908 EST 0n 01/13/04.
