Control Room Emergency Ventilation System Inoperable
On April 14, 2020 at 1645 CDT, the Control Room Emergency Ventilation Air Conditioning (CREV AC) system was declared inoperable when the electrical feed breaker to the Refrigeration Compressor Unit (RCU) was found in a tripped condition. As a result, both units entered Technical Specification 3.7.5 Condition A. Investigation is in progress to determine the cause and corrective actions of the RCU feed breaker trip.
The CREV AC 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) because the CREV system is a single train system, and loss of the CREV AC could impact the plant's ability to mitigate the consequences of an accident.
