| Title | Unusual Event Due to Range Brush Fire Near Plant |
| Event Description | The licensee declared an unusual event due to a range brush fire primarily involving tumbleweeds that is several hundred yards outside of the protected area. The basis for the declaration is EAL 9.4.U.3 for a fire near the plant that threatens to reduce the level of safety. The fire currently is not threatening anything (such as offsite power lines or buildings). The plant is not in any major limiting conditions of operation (LCO). The Hanford Fire Department has responded. The criteria for termination of the UE is when the fire is extinguished.
The licensee has notified State and local authorities and the NRC Resident Inspector.
At 1640 PST on March 28, 2006, Columbia Generating Station exited Unusual Event status due to the Emergency Action Level condition no longer being valid. The range fire reported earlier no longer has the potential to reduce the level of safety. The range fire is under control after burning approximately 0.4 acres approximately 150 yards southeast of the protected area boundary. Two engines from the Hanford Fire Dept. responded. No offsite power sources were affected or threatened. No press release is planned. The licensee notified the NRC Resident Inspector. R4DO(Powers), NRR EO(Gillespie), IRD(Wilson), DHS(Hill), and FEMA(Liggett) notified.
Event Notification 42450 has the statement 'The plant is not in any major limiting conditions of operation (LCO).' This statement should read 'The plant is not in any major Technical Specification Action Statements due to this event.' Unrelated to the declaration of the Unusual Event, the plant had a 125 V dc battery pilot cell that was inoperable per the requirements of TS 3.8.6. Applicable TS Action Statements were entered. At the time of the NOUE, plant personnel were in the process of restoring the battery to operability. The operability of the battery was restored at 1547 on 03/28/06. The licensee will notify the NRC Resident Inspector. R4DO (Powers) notified. |
