UNAVAILABILITY OF TSC VENTILATION SYSTEM DUE TO SCHEDULED MAINTENANCE
"At 0800 EST on Tuesday, January 4, 2011, the Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems were removed from service for scheduled maintenance.
"Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary .
"TSC ventilation system maintenance is scheduled to be completed by 1600 EST on Tuesday, January 4, 2011.
"The licensee has notified the NRC Resident Inspector.
"This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the loss of an emergency response facility,"
* * * UPDATE FROM BUD HINCKLEY TO DONALD NORWOOD AT 1709 EST ON 01/04/2011 * * *
"The TSC ventilation system maintenance was completed satisfactorily and the system was restored to service at 1705 EST."
The licensee will notify the NRC Resident Inspector.

TRITIUM VIAL CRACKED DURING MAINTENANCE OF MORTAR SIGHT UNIT
"On 4 January 2011 at 0900 hrs an Army National Guard employee was performing maintenance on a M64A1 sight unit in an attempt to remove the course elevation deflection scale on the sight unit which contained a 1 curie tritium lamp. The assembly is considered a module which is authorized by the licensee for replacement. During the removal of the scale assembly the tritium lamp was damaged. The worker immediately realized what had happened and called the local RSO to handle the incident. The State RSO was notified of the incident who in turn notified the US Army CECOM health physicist. The device was double bagged by the local RSO and placed in a designated LLRW storage area for future disposal. The local RSO performed contamination wipes of the device and surrounding works areas on Jan 4th. The arms room in the CSMS shop was immediately shut down and had limited access by authorized personnel. Wipe test results were received back from the Army lab on 6 Jan that indicated tritium contamination of 60 K dpm on the device itself and a few thousand dpm of the surrounding work bench. The RSO proceeded to decontaminated the affected contaminated areas and rewiped the work area to release it from radiological control. The second contamination survey (after decon) showed tritium contamination significantly reduced. At the time of this report the licensee does not have the final test results. The maintenance person involved in the incident was required by the licensee to have a tritium bioassay taken. Tritium bioassay results were not available at the time of the report. Investigation by the licensee is being conducted as to determine how the device was damaged during maintenance."
The event occurred at the New York Army National Guard, Combined Support maintenance Shop - Arms Room in Rochester New York.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
