Event Text
TECHNICAL SUPPORT CENTER VENTILATION SYSTEM NON-FUNCTIONAL
The following information was provided by the licensee via email and phone:
"On July 12, 2024, at 1337 EDT, operations discovered that the technical support center (TSC) ventilation system was non-functional, which resulted in an unplanned loss of the TSC that could not be restored within seventy-five minutes.
"If an emergency had been declared requiring TSC activation during this period, the TSC would have been staffed and activated using existing emergency planning procedures. If relocation of the TSC had been necessary, the emergency coordinator would have relocated the TSC staff to an alternate location in accordance with applicable site procedures.
"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 loss of the TSC ventilation system affected 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."
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
The TSC ventilation system remains out-of-service at the time of the notification. In the event of an emergency, the licensee will use the alternate TSC facility per applicable site procedures until the ventilation system is restored. Repair of the ventilation system is being worked around-the-clock.
