tion of an Unusual Event at its Diablo Canyon Power Plant Unit 2 near San Luis Obispo, California. An Unusual Event is declared for an other-than-normal plant related condition that does not require any emergency action by the general public or any government authorities.

An investigation to determine the cause of the fire is underway; at the same time Diablo Canyon personnel are mobilizing to make the necessary repairs to safely return the unit to full power.
There was no release of radioactive material to the environment from this event, as indicated by sensitive plant radiation monitors.
Unit 2 is shut down; Unit 1 continues to operate at 100 percent power.
