| ENS 42179 | 30 November 2005 21:54:00 | On November 30, 2005, at 1500 hours, the Control Room Emergency Ventilation Air Conditioning (CREV AC) system was declared inoperable due to failure of the associated air conditioning compressor. As a result, Technical Specification 3.7.5 Condition A was entered. 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. The licensee informed the NRC Resident Inspector. |
