Title | Technical Support Center Non-Functional Due to Tsc Ventilation Equipment Issue |
Event Description | The Technical Support Center (TSC) at the Point Beach Nuclear Plant (PBNP) is non-functional as a result of conservatively securing an exhaust fan that exhibited an abnormal noise in the TSC Ventilation system. The fan is currently in service and being monitored as part of the troubleshooting, with maintenance repair plans being conducted in parallel.
Functional alternate locations described in the emergency plan procedures for events resulting in radiological conditions affecting habitability will be used and are currently available. The Control Room or EOF will be selected as the alternate facility. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using the procedure and functional facilities selected. This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to the loss of an Emergency Response Facility (ERF). An update will be provided once the TSC ventilation system has been restored to normal operation. The licensee has notified the NRC Resident Inspector.
At 1737 on 9/14/12, maintenance activities are complete on the TSC ventilation system. The TSC ventilation has been restored to normal operation and the TSC [has been] returned to fully functional. The licensee has notified the NRC Resident Inspector. Notified R3DO (Kunowski). |
