The following was received from the State of Texas via email:
"On November 6, 2012, the licensee notified the Agency [State of Texas] that at approximately 0820 hrs one of its employees had discovered that a Troxler Model 3411B moisture/density gauge, containing one 8 millicurie cesium-137 source and one 40 millicurie americium-241/beryllium source, had been stolen from the company-owned vehicle while it was parked at his residence in Laredo, Texas, sometime during the preceding weekend. The licensee reported that the employee had left a temporary work site on Friday, November 2, 2012, and gone to his residence due to a family emergency and had failed to return the gauge to the licensed location. While the employee was loading the vehicle to go to a temporary work site this morning, he realized he had left the gauge in the vehicle over the weekend. When he checked the vehicle he found the chains had been cut the and gauge was gone. The license notified local law enforcement. More information will be provided as it is obtained per SA-300.

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.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AIRLINE UNDERGOING RE-ORGANIZATION UNABLE TO LOCATE VARIOUS RADIOACTIVE SOURCES
A representative for Pinnacle Airlines called to report that the company has records of various radioactive sources which cannot be located and are presumed lost. The airline is undergoing bankruptcy reorganization. The individual noted that the sources were previously registered under a company called Mesaba Airlines. Mesaba Airlines was at one time associated with Northwest Airlines. The individual believes that the devices were originally registered with the NRC as general licensed material. The material records indicate that the company was in the possession of 10 "Tritium Light Comparators" of approximately 1 curie each. The company has been able to locate 5 of these sources: In Knoxville TN; Memphis TN; Detroit MI; and Ft. Wayne IN. In addition, the company states that it had five explosive detector sources that are unaccounted for and (10 millicuries Nickel - 63 each) were last stored in Michigan (Esbaneba, Muskegon Kincheloe, and Gwinn MI). There may also be some missing Tritium Exit signs but the licensee has not been able to determine how many or where they were last located.
At this time, the licensee believes that this material is lost and that the responsible reporting agency is the NRC. The sources are registered on the generally licensed source tracking list. The licensee has discussed this information with NRC Region 3 (Reichhold).
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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |

The following was received from the State of Georgia via email:
"The Licensee reported to the Department [state of Georgia] on July 14, 2010 that a patient who received a prostate seed implant procedure on July 6, 2010 resulted in a medical incident. The patient was scheduled to receive a Cs-131 Isoray seed implantation for the prostate with a total planned activity of 194.3 mCi. During the procedure on July 6, 2010 it was noticed that many of the seeds implanted were not visible on ultrasound. Following final implantation of all the seeds, a cystoscopy was performed on the patient where it was revealed that 19 seeds were implanted in the bladder and not the prostate which was the intended implant site. All 19 seeds were removed from the bladder without difficulty. A post plan evaluation was completed the same day of the treatment. The total activity implanted (seeds implanted to the prostate) was determined to be 140 mCi with a difference of -54.3 mCi deviation from the total planned activity. Post plan D90 for the prostate was calculated to be 62.68% with a D90 deviation of 53.28 Gy from the dose prescribed of 85 Gy. An additional procedure was scheduled for the patient on July 12, 2010 where 18 seeds were implanted to bring the combined dose distribution to the prescribed amount.
"The department [Georgia Radioactive Materials] reported the incident to NMED in November 2012."
Georgia Incident Summary: GA-2010-07i

The following was received from the State of Texas via email:
"On November 7, 2012, the Agency [State of Texas] was notified by the licensee that one of its Troxler model 3411B moisture/density gauges had been damaged. The gauge contained one 8 milliCurie cesium-137 source and one 40 milliCurie americium-241/beryllium source. The operator had stepped aside to a nearby wall to get location information. A bulldozer operator assumed that this meant that the test was finished and drove into the area, impacting the gauge. The gauge was not run over, but suffered a bent top and damaged electronics. The licensee performed a survey and determined that the integrity of the sources and shielding were not impacted. The licensee has performed a leak test and will be returning the device to the manufacturer for evaluation. The investigation into this event is ongoing."

"This 60-day telephone notification is being made in accordance with the reporting requirements specified by 10 CFR 50.73(a)(2)(iv)(A) and 10 CFR 50.73(a)(1) to describe an invalid actuation of a general containment isolation signal affecting more than one system.
"On September 13, 2012, Browns Ferry Nuclear Plant (BFN) personnel completed the installation of three metal-oxide varistors (MOVs), MOV1, MOV2, and MOV3, on the governor of the 3C Emergency Diesel Generator (EDG) as part of a design change. On September 17, 2012, at 0312 hours Central Daylight Time (CDT), during post-modification testing of the 3C EDG, the Direct Current (DC) control circuit breaker tripped, causing a loss of governor control power for the 3C EDG. This event resulted in the loss of the 3B Reactor Protection System (RPS) Bus. In addition, Primary Containment Isolation System (PCIS) groups 3, 6, and 8 successfully isolated. The Steam Vault Booster Fan tripped and the 3B Steam Jet Air Ejector isolated. Standby Gas Treatment (SGT) Trains 'A' and 'B' and Control Room Emergency Ventilation Train 'A' initiated. The SGT Train 'C' was already in service for BFN, Unit 3, Reactor Zone Ventilation.
"Plant Conditions which initiate PCIS Group 3 actuations are Reactor Vessel Low Water Level or Reactor Water Cleanup Area High Temperature. The PCIS Group 6 actuations are initiated by Reactor Vessel Low Water Level, High Drywell Pressure, or Reactor Building Ventilation Exhaust High Radiation (Reactor Zone or Refuel Zone). The PCIS Group 8 actuations are initiated by Low Reactor Vessel Water Level or High Drywell Pressure. At the time of the event, these conditions did not exist; therefore, the actuation of the PCIS was invalid.
"The affected equipment responded as designed. On September 17, 2012, at 0335 hours CDT, Operations personnel restored the 3B RPS Bus.
"This condition was the result of MOV1 and MOV3 operating due to induced current in their associated ground cables. This resulted in grounds which tripped the DC control power breaker. To address this condition, MOV1 and MOV3 were permanently removed.
"There were no safety consequences or impact to the health and safety of the public as a result of this event. This event was entered into the Corrective Action Program as Problem Evaluation Report 610091.

"This 60-day telephone notification is being made per the reporting requirements specified by 10 CFR 50.73(a)(2)(iv)(A) and 10 CFR 50.73(a)(1) to describe an invalid actuation of a general containment isolation signal affecting more than one system.
"On September 18, 2012, at 0045 hours Central Daylight Time (CDT), during performance of surveillance procedure 1-SR-3.3.6.2.3(B), Reactor/Refueling Zone Ventilation Radiation Monitor 1-RM-90-141/143 Calibration and Functional Test, a Primary Containment Isolation System (PCIS) partial Group 6 isolation occurred. The partial Group 6 isolation caused the initiation of Standby Gas Treatment (SBGT) subsystems 'A' and 'B' and Control Room Emergency Ventilation (CREV) subsystem 'A', and the isolation of the Unit 1 H2O2 analyzer and the 1-RM-90-256 Continuous Air Monitor (CAM). Due to the isolation of the 1-RM-90-256 CAM, Operations personnel declared the drywall CAM inoperable and entered Technical Specifications (TS) Limiting Condition for Operation (LCO) 3.4.5 Condition B.
"Plant conditions which initiate PCIS Group 6 actuations are Reactor Vessel Low Water Level (Level 3), High Drywall Pressure, and Reactor Building Ventilation Exhaust High Radiation (Reactor Zone or Refuel Zone). At the time of the event, these conditions did not exist, therefore, the partial actuations were invalid.
"The affected equipment responded as designed. On September 18, 2012, at 0123 hours CDT, Operations personnel commenced restoring the affected systems to normal. At 0132 hours CDT, the 1-RM-90-256 CAM was returned to service, the SBGT subsystems 'A' and 'B' were secured, and TS LCO 3.4.5.B was exited. At 0133 hours CDT, the CREV subsystem 'A' was secured and at 0138 hours CDT, the Unit 1 hours analyzer was returned to service.
"This condition was the result of improper test setup during performance of 1-SR-3.3.6.2.3(B). It was determined that a jumper installed during the performance of 1-SR-3.3.6.2.3(B) to prevent an invalid actuation was not installed correctly. When the detector lead was lifted, an isolation signal was received. The surveillance procedure was stopped and the equipment was restored to pre-test condition.
"There were no safety consequences or impact to the health and safety of the public as a result of this event.
"This event was entered into the Corrective Action Program as Problem Evaluation Report 611238.
