The following information was received from the State of Georgia via email:
"Valmet was recently notified by one of their customers [WestRock MWV, LLC, Evadale, TX] regarding a leaking Kr-85 source in one of their general licensed [GL] devices that Valmet had supplied them a year or so ago. [Valmet personnel] retrieved the source and found that it was a slow leaker, and that it needed to be returned to the manufacturer. Valmet exchanged the source in the device and brought the faulty source back to Valmet's office to be returned to the manufacturer. The mill began to suspect a leaking source because of the operating parameters of the equipment. Valmet believes there were no exposures or ingestions of radioactive material, and will have the source returned to the manufacturer soon after the holidays when people are back to work. We expect them to let [the Georgia Radioactive Materials Program] know what the cause of the leak might be."

The following information was received via facsimile:
"On December 29, 2016, the Office of Radiological Health (ORH) was notified that radiation had been detected on a local law enforcement officer's personal radiation detector at the intersection of Route 123 and the I-95 southbound exit ramp in Woodbridge, Virginia. The Prince William County HazMat unit responded and identified the source as cesium-137 using a radioisotope identifier. The source was present in the grassy knoll in the median of the interchange. ORH and other agencies, including the Virginia State Police, Virginia Department of Emergency Management and FBI, participated in the initial investigation. The Virginia Department of Transportation, which had representatives at the location, has responsibility for this area and has been requested to arrange for mitigation of the source through the services of a radiation consulting company. Radiation levels were measured at about 10 mR/hr at 1.5 feet above the apparent location of the source and between 30 mR/hr and 50 mR/hr at ground level. Based on the radiation levels and the source location, no radiation exposure occurred to members of the public. The source is apparently below ground and will remain isolated and undisturbed until the Virginia Department of Transportation can arrange for the consultant to remove the item, analyze it, and arrange for its disposal. The consultant is enroute and expected to begin mitigation and disposal efforts late this afternoon. ORH is continuing its investigation and will update this notification when additional information is obtained."

The following update was received from the Virginia Radioactive Materials Program via facsimile:
"On December 29, 2016, the Office of Radiological Health (ORR) was notified that radiation had been detected at the intersection of Route 123 and the I-95 southbound exit ramp near Woodbridge, Virginia. The Virginia Department of Transportation (VDOT) took mitigation action. VDOT contacted a radiation safety consulting firm which arrived at the scene that evening. A metallic pellet was found after removal of about one inch of soil. The pellet was confirmed to be a cesium-137 source with an activity of about 8 millicuries and a contact exposure rate of 900 milliRoentgen per hour. It was approximately 7 millimeters in diameter and approximately 15 millimeters long. A field leak test of the source and surveys of the area after removal of the source indicated no contamination. The source was placed in a lead shield inside a DOT 7A Type A steel drum overpack. It was sent to the consulting firm's facility for temporary storage pending disposition. This notification will be updated if additional information becomes available."

The following information was received via facsimile:
"At approximately 1355 PST on Friday, 12/30/2016, Seattle Cancer Care Alliance called the Washington State Radioactive Materials Section to report a medical event. The event had occurred on Friday, 12/23/2016 but the date that the event was discovered was not provided. The summary of the event is as follows: An Ir-192 source was incorrectly positioned during an HDR procedure, resulting in a reduced dose to the treatment volume and an unintended dose to the surrounding healthy tissue. Limited information was provided by the licensee because they are still investigating the misadministration, but additional information will be provided in a follow-up conversation on Tuesday, 1/3/2017."

"During a routine inspection on December 6, 2016, Tennessee Valley Authority (TVA) found the Unit 2 Reactor Building Containment Vertical Tendon V281 rock anchor/tendon anchor coupling had failed. The anchor coupling appears to have sheared in the threaded portion allowing the anchor head for the vertical tendon and the anchor head for the rock anchor tendon to separate. TVA had inspected the failed tendon coupling on October 19, 2016, and identified no signs of component specific damage or improper installation creating the potential for an unknown common mode failure.
"Cause of Deficiency: At this time, the cause for the failure of the V281 rock anchor/tendon anchor coupling is unknown.
"Safety Significance: As noted previously, the cause for the failure of the V281 rock anchor/tendon anchor coupling is unknown. As a result, the extent of condition can not be determined at this time. If multiple containment tendons are found to be losing the capability to carry tendon design force, and this condition was left uncorrected, it could reduce the capability of the containment structure to perform its design function. TVA had previously completed an analysis of containment structure integrity considering a single tendon coupler failure as a result of a similar failure of a Unit 1 Reactor Building Containment Vertical Tendon V9 in 2009 and determined that the containment structure is maintaining its design capability.
"Interim Action: Upon discovery on December 6, 2016, the following actions were taken by BLN [Bellefonte] personnel:
Access to the Unit 2 tendon gallery was restricted. The area of the V281 tendon failure was subsequently cleaned. Grease samples were obtained and sent to TVA Central Labs for analysis. The couplings from both the rock anchor and tendon anchor locations were removed and sent to TVA Central Labs for metallurgical analysis. Grease samples were also collected from adjacent tendons (V272 through V290) to evaluate if conditions are similar to tendon V281 samples. The failure was entered into the BLN Corrective Action Program (Condition Report 1239343).
"Update Schedule: TVA plans to provide an update to this report by May 25, 2017 following the completion of the metallurgical and grease analysis."

| Event Text PART 21 - SEIZURE OF FUEL INJECTOR ON EMERGENCY DIESEL GENERATOR
The follow is a summary of the Part 21 report that was received via fax:
"Engine Systems Inc. (ESI) began a 10CFR21 evaluation on November 12, 2016, following the seizure of a fuel injector at Entergy Operations Inc. - Arkansas Nuclear One (ANO). ANO had completed installation of new fuel injectors on both of their EMD emergency diesel generator sets. During post-maintenance surveillance testing the fuel injector installed in the #7 cylinder of unit K4A seized (injector S/N 16C2 3186). During an attempt to shut down the unit, operators were unable to reduce the engine's load because of the seized injector/fuel rack.
"The seized fuel injector was then returned to ESI for failure analysis where it was received on November 16. The failure investigation determined that foreign material within the injector was the cause of the seizure. The report (8002768-FA) was completed on December 8, 2016, and submitted to the customer for review.
"The root cause of the failure was determined to be foreign material which likely entered the fuel injector during manufacture/assembly. Once the injector was installed on the engine, it was during engine surveillance (run) testing that this foreign material migrated into the plunger and bushing assembly. This decreased the running clearance between the components which ultimately lead to seizure.
"Component: EMD Fuel Injector, Part Number 40084720.
"Entergy Operations Inc.- Arkansas Nuclear One is the only customer to whom ESI has supplied suspect fuel Injectors." | |
