LOSS OF EMERGENCY ASSESSMENT CAPABILITY
"At 1748 EDT on September 12, 2020, Unit 2 emergency core cooling system (ECCS) leakage outside containment was determined to exceed the long-term habitability dose analysis for the Catawba Nuclear Station Technical Support Center (TSC) under bounding conditions. Repair options to arrest the leakage and restore functionality of the TSC are currently being evaluated.
"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 is no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
This same condition was reported under EN #54887.
