| Title | Technical Support Center Habitabilty Impacted Due to Loss of Air Conditioning |
| Event Description | At approximately 1018 EDT on March 17, 2014, during a check of facility equipment, the Technical Support Center (TSC) was found to be degraded due to the loss of the air conditioning (AC) system. Due to the loss of AC, TSC habitability is impacted.
The emergency assessment function can be performed in the control room as addressed in emergency response procedures. This event is reported in accordance with 10 CFR 50.72(b)(3)(xiii). This condition is common to both units. Unrelated to this condition, Unit 3 is currently in the process of shutting down in preparation for a refueling outage. Unit 4 will remain Mode 1, 100% Power. The TSC AC system repairs are in progress. The licensee has notified the NRC Resident Inspector.
The TSC AC system has been repaired and restored to service. The licensee will notify the NRC Resident Inspector. Notified R2DO (O'Donohue). |
