TECHNICAL SUPPORT CENTER VENTILATION SYSTEM OUT OF SERVICE
"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 (December 26, 2012) to the Technical Support Center (TSC) HVAC. The work entails removing power to the system fan and dampers to perform required preventative maintenance (PM) rendering the TSC HVAC non-functional during the performance of this work activity. This work activity is planned to be performed and completed expeditiously within about 16 hours including establishing and removing the clearance and performing post maintenance testing.
"If an emergency condition occurs that requires activation of the TSC, plans are to utilize the TSC concurrent with this work activity as long as habitability conditions allow. Additionally, plans are in place to expedite the return of the system should an emergency condition occur. The Emergency Response Organization duty team members will be relocated to alternate locations if required by habitability conditions in accordance with emergency implementing procedures.
"The licensee notified the NRC Resident Inspector."
* * * UPDATE FROM MARKO MALINEN TO CHARLES TEAL ON 12/27/12 AT 0810 EST * * *
As of 2100 EST on 12/26/12 the TSC has been satisfactorily tested and returned to service.
The NRC Resident Inspector has been informed.

RADIATION MONITOR USED FOR ASSESSMENT AND RESPONSE INOPERABLE DUE TO PRE-PLANNED MAINTENANCE
"At 0922 on 12/26/2012, R-16, Service Water System Effluent Line Radiation Monitor (for Containment Fan Cooling service water) was removed from service for scheduled maintenance. R-16 is used for Emergency Action Level (EAL) classifications of an unplanned release of liquid radioactivity to the environment that exceeds the requirements of the Offsite Dose Calculation Manual for an Unusual Event and an Alert, and is therefore being conservatively reported under 10 CFR 50.72(b)(3)(xiii) as a loss of emergency assessment capability. The maintenance was completed and R-16 restored at 1308 on 12/26/2012.
"R-16 is also scheduled to be removed from service for calibration on 12/27/2012 from 0800 -1400 CST."
The licensee has notified the NRC Resident Inspector.
