| ENS 56292 | 3 January 2023 12:47:00 | The following information was provided by the licensee via email: A Framatome employee preparing an area for painting experienced a hand injury when a heavy object fell on his hand. The worker was surveyed out of the area and confirmed to be free from radioactive contamination above free release limits and was transported to the local hospital (Kadlec Regional Medical Center) for treatment. The Washington State Department of Labor and Industry (WSDLI) was notified of this injury on 01/02/2023 at 1628 (PST). The work area has been quarantined pending investigation by WSDLI. This report is being made per the requirements of 10CFR70 Appendix A (c) concurrent reports because the nature of injury required reporting to WSDLI. |
| ENS 56290 | 30 December 2022 14:56:00 | The following information was provided by Kansas Radiation Control Program via email: Kansas Radiation Control Program was notified, at 1016 CST on December 30, 2022, that six tritium exit signs were disposed of inappropriately. A total of 17 tritium exit signs were removed from a church located in Topeka, Kansas, six signs were reported improperly disposed of with 11 remaining in the possession of the owner and later disposed of properly. The church had contracted with EMCOR to dispose of the signs and replace them with LED exit signs. The sub contractor, Mid-West Signs, reported they unintentionally disposed of six of the signs in the trash. Before this error was realized the trash was collected and the signs were determined unrecoverable. The signs were uninstalled on November 3, 2022; however it is unclear at this time when the signs might have been placed in the trash. This is an initial report and the incident is still open pending an investigation and management review. 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.

| ENS 56166 | 17 October 2022 13:27:00 | The following information was provided by the State of Ohio via email: On 10/12/2022, during routine maintenance and source exchange on an Elekta Flexitron HDR (High Dose Rate) unit the source became stuck in an unshielded position. The Elekta engineer immediately vacated the room and notified the medical physics staff and RSO (Radiation Safety Officer). The area was secured by the RSO, and measurements taken outside of the secured area were at background. Licensee security was posted outside of the area to prevent entry until Elekta personnel could secure the source. Additional Elekta staff arrived and secured the source on 10/13/2022, and it was shipped back to the vendor on 10/14/2022. Ohio Item number: OH220010 |
| ENS 56169 | 19 October 2022 15:09:00 | The following information was provided by the Minnesota Department of Health (MDH) via email: The Minnesota Department of Health was notified on 9/27/2022 of a lost localization seed (I-125, 0.188 mCi) that went missing on 6/30/2022. The seed was not identified as missing until 9/22/2022 during an audit. The specimen, with the seed, was transported to pathology and kept with the tissue during the processing of the sample. The pathologist believed the seed was non-radioactive due to the proper paperwork not being present with the seed (the licensee uses radioactive and magnetic seeds). The tissue specimen and seed were disposed of in the biohazard waste stream. Minnesota Event Number: MN220006 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.

| ENS 56202 | 3 November 2022 14:05:00 | The following information was provided by the licensee via email: This 60-day telephonic notification is being made in lieu of a licensee event report submittal as allowed by 10 CFR 50.73(a)(1). This notification is made pursuant to 10 CFR 50.73(a)(2)(iv)(A) to provide information pertaining to an invalid engineered safety feature actuation signal. On September 6, 2022, at Waterford 3, while performing a plant protection system (PPS) power supply check, technicians observed an abnormally high voltage output. When the technicians opened the PPS bay cabinet door to adjust the voltage, they then observed low voltage indications. The direct cause of this issue is believed to be vibration induced relay chattering or an intermittent connection issue when opening the rear doors of PPS cabinets. This resulted in half the logic being met for the Engineered Safety Feature Actuation Signal (ESFAS) signals to fully actuate. The ESFAS signal opened the following valves: EFW-228A (EFW to SG 1 Primary Isolation), EFW-229A (EFW to SG 1 Backup Isolation), EFW-228B (EFW to SG 2 Primary Isolation) and EFW-229B (EFW to SG 2 Backup Isolation). This was a partial actuation of ESFAS. Affected plant systems functioned successfully. The inadvertent actuation was caused by a spurious signal and was not a valid signal resulting from actual parameter inputs. The 1992 Statements of Consideration define an invalid signal to include spurious signals including jarring of a cabinet door. In accordance with 10 CFR 50.73(a)(1) a telephone notification is being made in lieu of submitting a written licensee event report. The NRC Senior Resident Inspector has been notified. These events did not result in any adverse impact to the health and safety of the public. |
