EN Revision Text: AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA DELIVERED TO WRONG ADDRESS

The following is a synopsis of information received via E-mail:

The Louisiana Department of Environmental Quality (LDEQ) was notified by the QSA Global Radiation Safety Officer (RSO) concerning an industrial radiography camera that had been shipped, but did not reach its intended destination on October 26, 2021. This notification was made via the LDEQ Radiation Hotline at approximately 1215 CDT on October 27, 2021. According to the QSA Global RSO, the common carrier said the package had been delivered on October 26, 2021 at 1550 CDT and signed for by an individual. The RSO for Ohmstede, the intended recipient, said the package had not been delivered. The package with the industrial radiography camera, a QSA Global model 880 Delta (s/n D11151) with 105 Ci of Ir-192 (s/n 34970M), was mistakenly delivered to an address on Hwy 75 instead of the correct address on Highway 30, St. Gabriel, LA. On October 27, 2021, the common carrier driver picked up the package from the incorrect address and delivered it to the correct location around 1300 CDT on October 27, 2021. No further action required.

Louisiana Event Report ID No.: LA 20210009

THIS MATERIAL EVENT CONTAINS A 'Category 2' LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

EN Revision Text: AGREEMENT STATE REPORT - FOUND Ge-68 SOURCE

The following information was received via E-mail:

"The Illinois Emergency Management Agency (the Agency / IEMA) was notified on 10/27/21 by Siemens Medical Solutions that a PET phantom source had been identified at a scrap recycling facility in Gilberts, Illinois. IEMA staff should be on site at approximately 1500 CDT today (10/27/21) to impound the source and assess for contamination. Updates will be provided as they become available.

"The radiation safety officer for Siemens Medical Solutions contacted the Agency to advise that a cylindrical PET phantom source (Ge-68, typically around 4 mCi) had been identified at Elgin Recycling. The Elgin Recycling facility is located in Gilberts, Illinois. Reportedly, the facility identified a shielded container (pig) and surveyed it prior to processing. Their handheld meter identified radioactivity and they contacted the manufacturer listed on the container (Siemens). Siemens advised the facility to secure the source away from the public and await pickup (likely late next week). Rather than have an unlicensed facility responsible for security, shielding and accountability of a licensed source; IEMA staff will facilitate pickup today and transfer the source over to Siemens staff when they are available next week.

"Preliminary information indicates the source was returned from India and sent to Hegele Logistics in Wood Dale, Illinois. Hegele Logistics failed to identify the source and sent the material for recycling. Agency staff have previously responded to Hegele Logistics in August of 2019. Siemens is researching the shipment to determine if additional sources could be present.

"Safety Assessment: Agency staff will retrieve information on the source and actions taken by Elgin Recycling staff which will facilitate a characterization of exposures, if any. Assuming the source has not decayed at all (271 day half-life), a 4 mCi Ge-68 source would have an exposure rate of approximately 2.3 mR/hour at one meter. The sources are typically a sealed, cylindrical epoxy not lending itself to removable contamination. Updates to this assessment will be provided."

Illinois Item Number: IL210034

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.

HIGH PRESSURE COOLANT INJECTION INOPERABLE DUE TO LOW LEVEL INSTRUMENTATION

"At 0241 [EDT] on June 3, 2021, during performance of a High Pressure Coolant Injection (HPCI) Condensate Storage Tank (CST) level functional surveillance, the HPCI torus suction inboard isolation valve was slow to open during swap of suction from the CST to the Torus. On June 9, 2021, it was determined that as a result of the June 3, 2021, slow swap condition, TS 3.3.5.1 Required Action D.1 to declare HPCI inoperable within 1 hour was applicable due to inoperable CST low level instrumentation channels. At 1817 [EDT] on June 3, 2021, HPCI suction was swapped to the torus, making TS Required Action D.1 no longer applicable. Reactor Core Isolation Cooling (RCIC) was available throughout this condition.

"At 0900 [EDT] on November 3, 2021, it was determined that an NRC event report due to HPCI inoperability should have been made. This event is being reported as a late 8-hour non-emergency notification pursuant to 10CFR50.72(b)(3)(v)(D) based on an unplanned HPCI inoperability.

"The cause of the slow valve opening was later determined to be corrosion products on contacts of a relay in the CST low level instrumentation logic. On June 4, 2021 at 1451 [EDT], the HPCI CST Level Functional Test was completed Satisfactorily, restoring HPCI Instrumentation to Operable.

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."

INCORRECT LOCAL LEAK RATE

"On 11/03/2021 Columbia Generating Station concluded the results for refueling outage 24 (R24) and 25 (R25) Local Leak Rate Testing as-found data was incorrect.

At 1231 PDT on November 3rd, 2021 Columbia Generating Station determined the local leak rate tests (LLRT) for the X- 25B containment penetration did not meet Technical Specification requirements for LLRT acceptance criteria. The incorrect LLRT data identified for residual heat removal (RHR) B Suppression Pool Spray containment isolation valve (RHR-V-27B) was from the previous two refueling outages (R24 on 5/22/2019 & R25 on 6/512021) at which time primary containment was not required to be operable. The corrected leakage assigned to the X-25 penetration also resulted in total Type B and C leakage summation exceeding the maximum allowable leakage rate for the primary containment (1.0 La) for R24 and exceeding 0.6La in R25.

The valve was flushed and retested satisfactory prior to entering the mode of applicability. This event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(ii)(A).

There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
