TECHNICAL SUPPORT CENTER (TSC) OUTAGE FOR PLANNED MAINTENANCE
"Planned preventive maintenance activities are being performed today (July 23, 2007) on the Hatch Nuclear Plant's Alternate Supply Breaker (5C) to the Diesel Generator Building Motor Control Center (MCC) (MPL # 1R24-S026). This MCC feeds the Technical Support Center (TSC) 480V AC distribution panel (MPL# 1R25-S102) which supplies power to the TSC HVAC. The work activities affecting the TSC are planned to be performed and completed expeditiously within one work shift (less than or equal to 6 hours). During this work activity the TSC HVAC system will be removed from service.
"If an emergency condition occurs that requires activation of the Technical Support Center during the time these work activities are being performed, it will take no more than three hours to return the equipment back to functional status, dependent on the stage of the work activity at the time the emergency occurs. Plans are to utilize the TSC for any declared emergency during the time these work activities are being performed, as long as radiological 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 1 since this work activity affects an emergency response facility for the duration of the evolution."
The licensee informed the NRC Resident Inspector.

"Update: On 07/23/07 at 1935 EDT, the HVAC System for the TSC was returned to functional status following the replacement of the alternate supply breaker to MCC 1R24S026. 1R24S026 was energized restoring power to the TSC HVAC System." R2DO (M. Lesser) notified.
The NRC Resident Inspector was notified of this event by the licensee.

MARYLAND AGREEMENT STATE REPORT - STOLEN TROXLER
At 1000 EDT on 07/23/07, the licensee notified the State of Maryland of a Troxler moisture density gauge that was stolen from a trailer at a temporary job site located at 11540 Berry Road, Waldorf, MD. The gauge is a Model 3430, serial # 22355, with an 8 millicurie Cs-137 source and a 40 millicurie Am-241:Be source. While the gauge was in storage, the source rod was locked, the gauge case was locked, and the gauge was stored in a locked trailer on the temporary job site. The local police have been notified and are investigating. The State of Maryland will issue a press release on 07/24/07 if the gauge is not recovered.
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.

AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA STUCK CONTROL ASSEMBLY
The State provided the following information via facsimile:
"During a routine maintenance inspection it was noted that the control assembly [of the radiography camera] would not project or retract the drive cable. After an investigation, it was found that 2 of 4 'small gear housing' screws were interfering with the gear teeth of the large gear.
"The two screws that interfere with the operation of the large gear only interfere when they are loose in the housing. Since the outside of the small housing is where the handle for the controls is kept, the screws inevitably come loose over time and use. Since the screws are applied in the housing there is no way to tighten the small housing screws with out disassembling the control arm assembly.
"A small design change is needed on these 4 small housing screws to prevent a source from stuck out in the shielded position."
Equipment involved: SPEC 150, (no serial number provided), Source: Ir-192 (no source strength provided), Control assembly: SPEC 'Red-Red' conduit control.
