| Title | Technical Support Center (Tsc) and Emergency Operations Facility (Eof) Ventilation System Out of Service |
| Event Description | This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) as the discovered condition affects the functionality of an emergency response facility.
A deficiency with the TSC and EOF ventilation system was discovered on October 29, 2016 at 1032 [EDT]. The deficiency involved a fire alarm unable to be reset impeding the ability to place the TSC and EOF in recirculation mode in the event of a radiological release. The fire alarm was reset at 1204 [EDT] on October 29, 2016, restoring capability to perform full emergency assessment to the TSC and EOF. If an emergency had been declared while the fire alarm was unable to be reset requiring TSC or EOF activation during this period, the TSC and EOF would be staffed and activated using existing emergency planning procedures unless the TSC or EOF became uninhabitable due to ambient temperature. radiological, or other conditions. If relocation of the TSC or EOF became necessary, the Emergency Response Manager would relocate the TSC and/or EOF staff to an alternate location in accordance with applicable site procedures. This condition had no impact on the health and safety of the public. The NRC Resident Inspector has been notified. A malfunctioning smoke detector was removed from the system. Compensatory measures are being employed. |
