| Title | Rain Causes Overflow of Rwst Water Basin |
| Event Description | The following voluntary report is being made as a result of the Industry Ground Water Protection Initiative NEI-07-07. During a heavy rain downfall on 7/11/2007, the U1 Refueling Water Storage Tank (RWST) water basin overflowed. This overflow was slightly contaminated due to prior contamination of insulation which surrounds the RWST. The rainfall is believed to [have leached] the contamination from the insulation to the basin. In accordance with NEI-07-07 guidance, a voluntary communication has been made to the appropriate State/Local officials. Thus the purpose of this notification is to inform NRC of this voluntary notification to State/Local agency. The release was less than regulatory (ODCM or 10 CFR 20 Appendix B) limits.
The licensee notified the NRC Resident Inspector. |
