LOSS OF TECHNICAL SUPPORT CENTER VENTILATION SYSTEM DUE TO PLANNED MAINTENANCE: 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 planned maintenance affects the functionality of an emergency response facility. Planned maintenance activities are being performed on 09/28/20 to the Peach Bottom Atomic Power Station (PBAPS) Technical Support Center (TSC) HVAC. The work includes replacement of supply fan and roof-top unit. Work is scheduled to complete on 10/11/20. If an emergency is declared requiring PBAPS TSC activation during this period, the PBAPS TSC will be staffed and activated using existing Emergency Preparedness (EP) procedures. If the PBAPS TS becomes uninhabitable due to radiological, or other conditions, the TSC Station Emergency Director will relocate the TSC staff to an alternate location in accordance with EP procedures. The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency. The NRC Resident Inspector will be notified by the licensee.
