PLANNED CORRECTIVE MAINTENANCE ON THE TECHNICAL SUPPORT CENTER (TSC) HVAC POWER SUPPLY
"This ENS [report] is being issued in advance of planned corrective maintenance on a TSC HVAC power supply.
"On 1/6/13 at 2000 [EST], the Technical Support Center Emergency Ventilation system will be removed from service to perform corrective maintenance on the load center that supplies power to the TSC HVAC system. The emergency ventilation system will not be available and cannot be restored within the time period required to staff and activate the Emergency Response Organization (ERO). The work is scheduled to complete on Friday 1/11/13 at 1500 [EST].
"If an emergency is declared and the TSC activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological or other conditions. The Station Emergency Director would assess habitability in accordance with station procedures. TSC relocation of personnel would be directed as required until such time that the TSC ventilation system is returned to service.
"An update will be sent upon TSC HVAC restoration."
The licensee has notified the NRC Resident Inspector.
