| Title | Loss of Power to Emergency Sirens Due to Severe Weather |
| Event Description | On August 7, 2013, at 0345 [CDT], Kewaunee Power Station was notified that a loss of alert sirens impacting greater than 50% of the Emergency Planning Zone population are non-functional due to a loss of power. The sirens are used to provide a public prompt notification. The sirens lost are those that Point Beach Nuclear Power Plant takes primary responsibility. Power was lost to them during a severe thunderstorm and the expected out of service time is unknown at this time.
This condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that results in a major loss of emergency assessment capability. The NRC Resident Inspector has been notified. See related EN#49246
Most emergency sirens have been returned to service such that the lost coverage is now only 24%. The licensee notified the NRC Resident Inspector. Notified R3DO (Lara). |
