The following information was received from the State of Texas via email:
"On August 3, 2015, the licensee reported to the Agency [Texas Department of State Health Services] that one of its technicians had run over and damaged a Humboldt 5001 EZ moisture/density gauge at a temporary job site in Belton, Texas. The gauge contained a 10 millicurie cesium-137 source and a 40 millicurie americium-241/beryllium source. The technician had started the test and the cesium source was extended four inches into the ground. The technician decided to move his pickup and while doing so he backed over the gauge and then pulled forward over it again. The source rod handle broke completely off of the gauge. A boundary around the gauge was marked and the licensee's radiation safety officer called a licensed service company. The service company responded and reported that the source was inside the gauge and not down in the hole, that it had apparently been pulled back into the gauge when it was run over. The service technician performed surveys and found no contamination. No member of the public received any exposure as a result of this event. No elevated exposures are anticipated for the technicians. An investigation into this event is ongoing. More information will be provided as it is obtain in accordance with SA-300."

The following information was provided by the State of California via email:
"RHB [ California Radiation Heath Branch] personnel noted irregularities in the way brachytherapy was being performed by an authorized user and investigated all facilities where he is authorized to perform brachytherapy.
"On August 3, 2015, after reviewing files and consulting with the RSO of the facility, it was determined that there had been two medical events that had gone unreported. Both events were prostate Pd-103 implants performed in 2013 and 2014. One treatment resulted in a dose of only 37.6 percent of the target dose to the prostate (139.5 mCi Pd-103) and the second resulted in a dose of 66.9 percent of the target dose to the prostate (189.1 mCi Pd-103). The licensee will submit a follow up report within 15 days."

On 7/31/2015, a patient was undergoing a single treatment for liver cancer using Y-90 microspheres (SIR-Spheres) with a prescribed dose from the physicians written directive of 29.43 milliCi. On 8/4/2015, it was discovered that the patient actually received 38.2 milliCi dose due a calculation error based on the physician's initial written directive when the physician had decided on a final dose reduction prior to treatment. The physician has been notified and believes that there will be no adverse effects to the patient. The patient will be notified on 8/5/2015.

"At approximately 2332 EDT on August 10, 2015, the Ginna Control Room was notified of an inadvertent siren activation by the Monroe County Emergency Center. It is unclear at this time why the siren inadvertently activated. Company personnel are addressing the issue with the siren.
"The licensee notified the NRC Resident Inspector."
The siren activated for approximately 1 minute. The licensee will remove the siren from service until the cause of the inadvertent actuation can be corrected. The licensee has a sufficient number of sirens to allow this siren to be removed from service. |

"Reactor trip caused by turbine trip. Turbine tripped immediately following the trip of one of four 345KV offsite lines. The reason for protective relaying not preventing the grid disturbance from tripping the turbine generator is not known at this time. All normal offsite and onsite power sources are available.
"Auxiliary Feedwater actuated as expected on low steam generator level following the trip from 100% power. All systems functioned as expected in response to the trip.
"The NRC Senior Resident Inspector has been notified."
An electrical fault on a 345 kV line 2 miles from the site caused the bus to strip and reclose, which cleared the fault. All control rods fully inserted and the plant is in its normal shutdown electrical lineup. |

| Event Text PART-21 NOTIFICATION - MICRO SWITCH INTERMITTENT VARIATION IN RESISTANCE
The following report was received via fax:
"On June 4, 2015, Rotork Controls Inc. opened a formal Part 21 [10 CFR 21.21] investigation into a self-identified anomaly relating to a basic micro switch - Pt No N69-921, description 'V12'. The anomaly is intermittent variation in electrical contact resistance and was first observed during the factory acceptance test of a Rotork safety related NA Range Electric Actuator; also referred to as an electric Valve Operator.
"Rotork and the switch manufacturer are currently characterizing switch population contact resistance to establish whether an unsafe condition could exist as defined under 10 CFR 21." | |
