| Event Text AGREEMENT STATE REPORT - SOURCE RECEIVED WITH EXTERNAL CONTAMINATION
The State reported that QSA Global received a radioactive source shipment that had external contamination on the source (but internal to the shipping container) and evidence of leakage. The source originated from Westex Company of Oxnard, California. The source was an old Amersham source Model T-2-T, S/N C778 containing an estimated 7.1 curies of Cobalt-60. The source was sent to QSA for disposal. It had been in long-term storage at the Westex facility.
When the shipment arrived at QSA, it was receipt inspected and found to be clean on the outside of the Type B shipping package. When the package was opened and interior swipes taken, surface contamination was discovered on the source exterior. The highest swiped reading obtained was about 1.17 microCuries of Co-60.
QSA does not believe that any contamination ever existed exterior to the package during transport or preparation of shipment at the originator's site. The source has been stored in the container at Westex without use or removal from the container for decades. QSA Global has been in contact with Westex about the contamination and Westex confirmed no contamination at their facility.
QSA plans on disposing of the source. |

| Event Text AGREEMENT STATE REPORT - NUCLEAR DENSITY GAUGE DAMAGED WHEN STRUCK BY VEHICLE
The following information was received via facsimile:
"A nuclear gauge, Troxler Laboratories 4640 Thin Lift density gauge, Serial No. 1997, Nuclide CS-137, GBq 0.296, mCi 8, was damaged in a construction zone hit-and-run accident. The RSO for a construction company was carrying the thin lift gauge to his truck when he was struck by a female driver in a grey sedan. The RSO, who was approximately 10 feet inside the coned area of the construction control zone, was able to move his body at the last minute and did not sustain major injuries. The gauge was destroyed but the source remained intact in the damaged housing. The RSO and the Nevada Highway Patrol [NHP] conducted radiation surveys.
"NHP contacted Radiation Control Program 30 minutes after notified. The licensee reported to RCP within 3 hours.
"The damaged gauge has been leak tested and is stored at the licensee's facility pending instruction from Troxler on shipping for disposal."
The State of Nevada has not yet assigned a state event number. |

"Technical Support Center (TSC) HVAC unit [was] taken out of service for maintenance on [the] unit. The maintenance to be performed includes replacing the evaporator coil, the fan and the expansion valve. This work will be performed with high priority around the clock until the work is completed. Equipment unavailability hours will be reported to and tracked by the TSC HVAC System Engineer. Compensatory measures for performing essential TSC functions during this maintenance period have been established. These measures include the relocation of the TSC staff in the event of a declared emergency if the Emergency Director deems the TSC uninhabitable. The maintenance period is scheduled to last 13 to 16 hours, at which point the TSC HVAC [unit] will be restored to operable status."

"At 2132 [EDT] on 9/22/2010, [the licensee] received a breaker tripout associated with the intertie transformer. Switching was ongoing in the switchyard at the time. At 2135 [EDT], the MCR [Main Control Room] was notified that flames were present on the A intertie transformer. NOUE was declared at 2154 [EDT]. The state of Tennessee was notified at 2200 [EDT]. There have been no observable effects on other plant equipment or structures at this time. This occurrence does not affect safety related equipment.
"Flames were extinguished at 2154" [EDT].
The intertie transformer converts power between the 500 kV and 161 kV power lines. The transformer spilled an unknown quantity of oil into the gravel sump surrounding the transformer. The fire was extinguished by the onsite fire brigade and no offsite assistance was required.
The licensee notified the NRC Resident Inspector.
