| Title | Offsite Notification Due to Fish Kill |
| Event Description | At 1249 CDT on 06/23/09, it was discovered that a fish kill took place in LaSalle County Nuclear Station's cooling lake, due to increased temperature. As summer air temperatures increased, the cooling lake temperature increased above 93?F, the threshold at which species susceptible to increased temperature begin to perish. It was communicated to the Illinois Department of Natural Resources (IDNR), that a fish kill has occurred. Efforts are under way to contact the IDNR district fish biologist to quantify the mortality.
This notification is made in accordance with Exelon Reportability manual SAF 1.9, ENV 3.26, LaSalle County Station Facility Operating License Appendix B Section 4.1 'Unusual or Important Environmental Events', and 10CFR50.72(b)(2)(xi). The licensee notified the NRC Resident Inspector. |
