Title | Loss of Emergency Siren Capability Due to Power Outage |
Event Description | The purpose of this 8 Hour notification is to inform the Nuclear Regulatory Commission of a Loss of Emergency Preparedness Capabilities per NUREG 1022 and 10CFR50.72(b)(3)(xiii). Specifically, at 1455 central standard time on 3/28/05, Point Beach Nuclear Plant was notified that Emergency Plan Sirens, P012, P013, and P014 were out of service. These three sirens constitute 59.32% loss of population coverage.
The time that the emergency sirens went out of service was 1343 CST, 3/28/05. These sirens are fed from Two Rivers Water/Light (WIPPI). Point Beach Nuclear Plant has contacted Manitowoc County Dispatch at 1517 of the loss of population coverage, and subsequent power restoration. Two Rivers Municipal Utilities has restored power to the Emergency Plan Sirens at 1533 on 3/28/05. The licensee informed the NRC Resident Inspector.
The licensee faxed the following update: The purpose of this update is to provide additional clarification to EN#41538. At 1343 CST, Emergency Plan Siren P012 went out of service due to a power outage. The loss of P012 represents a 3.38% loss in population coverage in and of itself. At 1502 CST, Emergency Plan Sirens P013, and P014 went out of service due to a power outage. When all three sirens are out, as they were from 1502 to 1533 CST, the loss of coverage to the population is 59.32%. Power was restored to Emergency Plan Sirens P012, P013, and P014, and they were returned to service at 1533 CST. The remainder of EN#41538 remains accurate as written. The licensee informed the NRC Resident Inspector. Notified the R3DO( Riemer). |
