TECHNICAL SUPPORT CENTER OUT OF SERVICE
"An alarm was observed in the Technical Support Center (TSC). Initial investigation revealed the TSC to be warmer than usual and alarm 'TSC Vent Air Handling Unit B001 Disch Low Flow' was annunciated on the local panel. Annunciator response was followed as per 34SO-X75-002-0 with maintenance assistance. Further investigation revealed that the 1X75B001 Air Handling Unit fan belt was broken which made the TSC non-functional. The availability of the alternate TSC was verified as required. Actions are in place to return the TSC to functional status.
"If an emergency condition occurs that requires activation of the TSC, plans are to utilize the TSC as long as habitability conditions allow. 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.
"This event is reportable per 10CFR50.72 (b)(3)(xiii) as described in NUREG-1022, Rev. 2 and TRM T3.10.1 since the facility was rendered non-functional for greater than 30 minutes.
"The TSC was returned to FUNCTIONAL status at 0430 EDT on 6/19/2013."
The licensee notified the NRC Resident Inspector

TECHNICAL SUPPORT CENTER PLANNED MAINTENANCE
"Planned breaker maintenance activities will be performed today (Wednesday, June 19, 2013) which will temporarily remove power to the Quad Cities Station TSC. The maintenance will be completed in approximately 2 hours and is scheduled to be worked continuously to minimize out-of-service time.
"If TSC activation is required during this period, compensatory measures have been established to direct ERO [Emergency Response Organization] members to an alternate location. No other emergency response facilities are impacted by the breaker maintenance. This event is reportable per 10CFR50.72(b)(3)(xiii) since the scheduled maintenance affects an emergency response facility.
"The NRC Resident Inspector has been notified."
