UNPLANNED TECHNICAL SUPPORT CENTER VENTILATION MAINTENANCE
"At 2100 on June 21, 2020, a condition was discovered which will require corrective maintenance activities to be performed on the Technical Support Center (TSC) HVAC. The work will include repair of the Condensing Unit system. The estimated duration of repair is unknown at this time.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to the alternate facility.
"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the discovered condition of the TSC affects the functionality of an emergency response facility.
"There was no impact on the health and safety of the public or plant personnel.
"The NRC Resident Inspector has been notified."
