| UNUSUAL EVENT DECLARED DUE TO UNCONTROLLED BRUSH FIRE THREATENING OFFSITE |
| POWER SUPPLIES |
| |
| The licensee declared an Unusual Event at 1526 PDT due to an uncontrolled |
| brush fire near the site. The licensee was performing a controlled burn of |
| grasses near the site when the fire went out of control. Heavy smoke from |
| the fire caused a fault on the incoming 230kV power line, resulting in a |
| loss of startup electrical power to both units. All six EDGs automatically |
| started, but did not load. The licensee has notified local government |
| agencies, and has requested assistance from the California Department of |
| Forestry. The NRC resident inspector is currently onsite. |
| |
| * * * UPDATE 1913 EDT 4/5/01 FROM SKAGGS TAKEN BY STRANSKY * * * |
| |
| The licensee reported that the fire has been extinguished. Startup power has |
| been restored to the startup transformers, with restoration of power to |
| individual buses still underway. |
| |
| * * * UPDATE 2005 EDT 4/5/01 FROM SKAGGS TAKEN BY STRANSKY * * * |
