| Title | Emergency Offsite Facility/Technical Support Center Ventilation Maintenance |
| Event Description | This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the work activity affects the functionality of an emergency response facility.
Planned maintenance activities are being performed today to the Emergency Offsite Facility (EOF)/Technical Support Center (TSC) HVAC. The work entails replacement of a pressure switch. The filtration portion of the system will not be affected by this work. This work activity is planned to be performed and completed expeditiously within about 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> including establishing and removing the clearances and performing post maintenance testing; however, restoration time required during the maintenance could exceed the time required to activate the TSC. If an emergency condition occurs that requires activation of the EOF and TSC, plans are to utilize the EOF and TSC during the time this work activity is being performed as long as habitability conditions allow. The Emergency Response Organization team members will be relocated to alternate locations if required by habitability conditions in accordance with emergency implementing procedures. Alternate emergency response facilities will remain available in the event that relocation is necessary." The licensee has notified the NRC Resident Inspector. Licensee has also notified state and local agencies.
The maintenance work was completed. The TSC and EOF were declared operable as of 1025 EDT. The licensee will notify the NRC Resident Inspector. Notified R2DO (Lesser). |
