MISSING PO-210 SOURCE
A 50 µCi Po-210 source has been discovered missing. The source was leased from a vendor under a general license. The caller stated that the source had been used in a science fair project, and then inadvertently discarded into the trash. The university is currently attempting to determine whether the trash from this residence was taken to a sanitary landfill or an incinerator.

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 * * *
The Unusual Event was terminated at 1700 PDT. Startup power has been restored to all individual buses. Notified R4(Brockman), NRR (Grimes), FEMA (DePuy).
