Columbia Generating Station has declared an unusual event ([EAL] 9-3.U.1) due to an unintentional vehicle crash into the Radwaste Building (Safe-Shutdown Bldg) roll-up door during the normal course of plant activities. Damage to the door has prevented normal closure of the door. Efforts to close the door are on-going.
Terminated the event @ 1655 [PDT] due to determination that an unusual event did not exist.
A plant employee was using a plant-owned vehicle to move a sea-land container into the Radwaste Building when he struck the bottom of the roll-up door. There were no injuries to plant personnel and no other damage to plant equipment.
The licensee has notified the NRC Resident Inspector.
The following retraction was obtained from the licensee via facsimile (licensee text in quotes):
At 1912 EDT on April 5, 2005, NRC was notified of an Unusual Event at Columbia Generating Station (EN #41565). This notification also informed the NRC that the event was terminated at 1955 EDT (1655 PDT) on April 5, 2005.
This is a follow-up to inform the NRC that Columbia Generating Station is retracting its Unusual Event Declaration due to the following reason. Columbia Generating Station Procedure 13.1.1A requires entry into Unusual Event EAL 9.3.U.1 if 'the impact is of such force that damage to structures or equipment inside a Safe Shutdown Building may have occurred.' Upon further evaluation, the impact was not of sufficient force to have caused damage to structures or equipment inside a Safe Shutdown Building. Based on this information, the Unusual Event criteria was not met.
The licensee notified the NRC Resident Inspector and local, State, and other Government Agencies of this update.
