TECHNICAL SUPPORT CENTER HVAC OUT OF SERVICE
"Due to unsatisfactory performance of TSC HVAC operation, the system is removed from service for corrective maintenance under Operating Permit 1ÀOP-11-1X75-00211.
"The TSC HVAC is considered non-functional during the performance of this corrective work activity. If an emergency condition occurs during the time these work activities are being performed, which requires activation of the TSC, the contingency plan calls for utilization of the TSC, as long as radiological conditions allow for habitability of the facility. Procedure 73EP-EIP-063-0, Technical Support Center Activation, provides instructions to direct TSC management to the Control Room and TSC support personnel to the Simulator Building to continue TSC activities if it is necessary to relocate from the primary TSC so that TSC functions can be continued.
"This event is reportable per 10CFR50.72 (b)(3)(xiii) as described in NUREG-1022, Rev. 1 since this activity affects the functionality of the TSC emergency response facility for the duration of the evolution."
The NRC Resident Inspector has been notified.
* * * UPDATE FROM FRANK GORLEY TO PETE SNYDER AT 2041 EDT ON 7/31/11 * * *
The TSC HVAC system is back in service as of 1700 EDT on 7/31/11 following compressor replacement.
The licensee notified the NRC Resident Inspector.
