EN Revision Text: AGREEMENT STATE REPORT - LOST GAUGE LOCATED IN OKLAHOMA

The following information was provided by the Illinois Emergency Management Agency (IEMA, The Agency) via email:

"On 05/17/22, a shipment of scrap metal being hauled from Sallisaw, OK to Rogers, AR tripped a portal monitor at the receiving recycling company. It was returned to Oklahoma under DOT-SP AR-OK-22-007. The load was surveyed once returned to Oklahoma and a Thermo Measure Tech model 5201 fixed gauge containing 50 mCi of Cs-137 (s/n B4473) was identified.

"The gauge has since been isolated in a drum and secured in a shed at the Oklahoma recycling facility. Efforts to identify the owner resulted in a call from Oklahoma Department of Environmental Quality (OK DEQ) to the Illinois program on 5/27/22. IEMA staff were able to identify Mid America Dredging in Good Hope, IL as the owner. Mid America Dredging is registered with the Agency under #9223884 and last reported the gauge as present on 2/15/22.

"Agency staff requested the licensee confirm the gauge was on site and send pictures. Apparently, the `device' the registrant has been exercising control over since 2015 was the outer housing for the gauge which may have a secondary label according to the Sealed Source and Device (SSD) sheet. The licensee suspects the gauge was inadvertently disposed of or abandoned during work in Sallisaw, OK in or around 2015.

"IEMA will address noncompliance with the registrant. This device is generally licensed and registered under 32 Ill. Adm. Code 330.220(a)(4). Due to the activity involved, any loss, theft or diversion is immediately reportable under 32 Ill. Adm. Code 340.1210(a). The registrant did not report, nor was seemingly aware of the loss.

"OK DEQ notified the Headquarters Operations Officer on 5/18/22, and provided an update on 5/27/22. This NMED entry is made to document IEMA actions and track until the gauge is properly returned and/or disposed of. Updates will be provided as they become available."

Reference Event Number 55900 for the initial notification from OK DEQ to the NRC.

AGREEMENT STATE REPORT - DOSE TO EMBRYO/FETUS

The following was received from the Illinois Emergency Management Agency (IEMA) via email:

"The RSO [(Radiation Safety Officer)] for the licensee contacted IEMA to report that on March 2, 2022, a patient was administered a 100 mCi I-131 dose. A pregnancy test was performed in advance of the administration and indicated negative (not pregnant). On April 13, 2022, the RSO received a call notifying him the patient was determined to be 7 days pregnant when the administration occurred. The patient was informed and returned to the hospital to do a whole-body count as a means to estimate biological half-life. The licensee has calculated upwards of 20 microCi of I-131 was retained by week eleven of the pregnancy and 75 percent was taken up by the fetus. Dose prior to eleven weeks was reportedly estimated as that to the maternal uterus (ICRP 88 states this is accurate to 8 weeks). It is unclear if the calculation methodology used was consistent with RG 8.36 (NUREG/CR-5631) or ICRP 88 but will be reviewed when staff investigate.

"The licensee is estimating the dose to the fetus through 12 weeks of development as 266 mGy (26.6 rads)."

Illinois Item Number: IL220018

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following was received from the California Department of Public Health via email:

"On May 31, 2022, the RSO of Alta California Geotechnical, Inc. (Alta), contacted the Brea office of the California Department of Public Health to report a stolen moisture density gauge. The gauge was a CPN model MC-3 S/N M3811862 (10 mCi Cs-137, 50 mCi Am-241:Be). On May 27, at approximately 1700 PDT, the gauge was placed in a locked Mobile Mini (temporary storage) container in a fenced (also locked) area of the construction site in Jurupa Valley, California. The theft occurred sometime between Friday, May 27 and Tuesday, May 31. When Alta personnel arrived at the construction site at approximately 0500 PDT Tuesday morning, they discovered that the storage container lock (a hidden shank/"hockey puck" style) was drilled through and the locked transportation case containing the gauge was removed, along with other equipment. Alta personnel searched the surrounding area until approximately 0630 PDT and then contacted the Riverside County Sheriff to report the theft. The licensee's investigation into this event is ongoing and will be reviewed further by the California Department of Public Health."

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.

EN Revision Text: AGREEMENT STATE REPORT - DELIVERED SOURCE NOT SECURED

The following licensee provided information was forwarded from the Mississippi State Department of Health via email:

"A replacement Ir-192 source [(100 Ci)] was ordered from QSA Global on 3-24-22. QSA sent an `Advanced Shipping Notice' email after hours at 1800 CDT on 5-26-22. The source arrived the following day, Friday, 5-27-22. The source was delivered to the Shipping/Receiving dock (building 9145), operated by S3 [(Syncom Space Services)]. (Note: the standard practice is for the source to be delivered directly to the building where S3 licensed sources are secured.) The Receiving worker signed for the shipment at 1000 CDT on 5-27-22. The Receiving worker is not a radiation safety qualified employee. The RSO [(Radiation Safety Officer)], nor any other radiation safety qualified personnel were contacted upon delivery of source. The RSO was not at work on Friday, and unaware the source was being delivered that day. The source was in the Shipping/Receiving building (locked when personnel are not on site) until Tuesday morning, 5-31-22. Upon arrival to work at 0600 CDT Tuesday morning, the RSO read the email from QSA Global and checked the tracking information. At that time, he realized the source had been delivered. The RSO identified which Receiving worker signed for the source. Their shift starts at 0700 CDT. Upon their arrival, the RSO verified that the source was at the Shipping/Receiving building. The RSO immediately picked up the source and brought it to the secure vault. Management was then notified, and the investigation began.

The S3 Heath Physics Coordinator and RSO (with concurrence from NASA HP [(Health Physicist)]) concluded that no employee was exposed to an unallowable amount of radiation based on where the source was placed and its proximity to employees in the area. The investigation is ongoing to identify the process failures that lead to this incident. NASA has been notified and the incident has been entered into a formal tracking system."

UF6 LEAKAGE INSIDE AUTOCLAVE

The following information was provided by the licensee via email:

"The plant is in a safe configuration. On June 3, 2022, isolated pressure fall (IPF) and isolated pressure rise (IPR) tests were completed satisfactory on manifold 1. A satisfactory Item Relied on For Safety [IROFS] surveillance was completed for manifold 1 and 1003 Autoclave was placed in service. On June 7, 2022 during the disconnect of 1003 Autoclave, an Operator noticed a white/yellowish film on the hex nut of the manifold and the upper portion of the cylinder valve. The Operator surveyed the film and found 4,000 to 6,000 dpm alpha and beta contamination. Prior to opening the door of 1003 Autoclave, the internal atmosphere was sampled for hydrogen fluoride (HF). No HF was detected by HF monitor. 1003 Autoclave has been taken out of service. Autoclave sampling manifold 1 has been isolated and IROFS 28 declared INOPERABLE."

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
No employee exposures occurred. The leakage was contained inside the autoclave.
