WATER FOUND IN CONTROL ROOM EMERGENCY VENTILATION AIR FILTRATION UNIT
"On October 27, 2019, at 1605 CDT, the Control Room Emergency Ventilation (CREV) was declared inoperable due to finding water in the system's Air Filtration Unit (AFU) filter enclosure. Technical Specification 3.7.4, Condition A, was entered which requires the CREV system to be restored to an operable status in seven days. No other systems were out of service at the time this was declared inoperable.
"The CREV system maintains a habitable control room environment and ensures the operability of components in the control room emergency zone during accident conditions.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(v)(D), "Event or Condition That Could Have Prevented Fulfillment of a Safety Function," because the CREV system is a single train system required to mitigate the consequences of an accident.
"The licensee has notified the NRC Resident Inspector."
