"Make: Agilent Technologies Gas Chromatograph, Model 7890A, SN: CN12421187, Detector: G2397A, Source Model: E&Z NER-004P.

"Source Serial Number: U37072, Original Activity: 13.2 millicuries Ni-63 (May 2020), Current Activity: 13.05 millicuries Ni-63 (as of Discovery Date: January 5, 2022). U37072 Leak test result: 0.0056 microcuries of removable contamination wiped from its inlet/column adapter.

"Source Serial Number: U38668, Original Activity: 13.2 millicuries Ni-63 (May 2021), Current Activity: 13.14 millicuries Ni-63 (as of Discovery Date: January 5, 2022). U38668 Leak test result: 0.0495 microcuries of removable contamination wiped from its inlet/column adapter.

"Immediate corrective actions were performed by the Agreement State Radioactive Materials Licensee, as described in Arkansas State Board of Health Rules for Control of Sources of Ionizing Radiation RH-402.c.5. Corrective actions included immediately suspending operations of device, device was tagged-out and taped shut, and properly posted.

EN Revision Text: AGREEMENT STATE REPORT - STOLEN X-RAY FLUORESCENCE DEVICES
The following information was obtained from the state of New Jersey Radioactive Materials Program (NJ RMP) via email:

"On 2/17/2022, staff [at NJ RMP] was notified via police report that two XRF devices were stolen from the licensee's location in March of 2021. This notification resulted from an investigation initiated by NJ RMP staff to obtain unpaid licensing fees in January 2022. While doing so, staff found that the RSO died in March of 2021 and the licensed storage location was for sale. Staff were able to make contact with the estate lawyer to attempt to locate the devices. On 2/17/2022, the estate lawyer forwarded staff a police report filed on 3/9/2021 reporting the stolen devices and other items. No follow up to find the stolen items was done by the police or family members. No further investigation is expected. The license was revoked on 2/23/2022."

Device 1 was manufactured by RMD Instruments, Inc., model LPA-1, serial number 1183, containing 12 mCi of Co-57.
Device 2 was manufactured by Viken Detection, model Pb200i, serial number 2537, containing 5 mCi of Co-57.

NJ Investigation number: 448354-INV220001

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 - STUCK SHUTTER ON FIXED GAUGE

The following was received from the Tennessee Division of Radiological Health via email:

"An in-line fixed gauge was discovered to have a stuck shutter. Licensee attempted to use penetrating lubricant without success. Licensee has contacted VEGA field technician to attempt to unstick the shutter. If technician is unsuccessful, the plan is to immediately replace the gauge. The following is the technical information on the gauge:

"Manufacturer: Ohmart/Vega
"Model: SHF1
"Gauge SN: (Will be sent with 30-day report)
"Isotope: Cs-137, 20 mCi (1993)
"Source SN: 9274GG
"Source Holder Model: SHF1-45

"Corrective actions will be updated with a report within 30 days."

PART 21 - POPPET SEAL FAILURE

The following information was provided by the licensee via fax or email:

"This is a non-emergency notification required by 10 CFR 21.21(d)(3)(i). A written notification in accordance with 10 CFR 21.21(d)(3)(ii) will be provided within 30 days.

"On June 22, 2021, VC Summer Nuclear Station (VCSNS) received information indicating that a poppet seal failure in the Feedwater Isolation Valve (FWIV) 'B' control block was due to laminations in the Viton material. The failure occurred on May 12, 2021 and was captured in the corrective action program as CR-21-01263.

"VCSNS completed a Substantial Safety Hazard Evaluation and determined that the laminations in VCSNS poppet seal lots 7064051 and 7081558 constituted a substantial safety hazard. The FWIV poppet seals are responsible for retaining and directing pressurized air to each side of the FWIV actuator for repositioning and maintaining FWIV position in both the open and closed positions.

"The NRC Senior Resident Inspector has been notified."
