EN Revision Text: AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following was received from the California, Department of Health, Radiologic Health Branch (RHB Brea) via email:

"On July 11, 2022, at approximately 1100 PDT, [redacted], the radiation safety officer (RSO) of Premier Testing & Inspection, Inc., Radioactive Materials License #7988-33, contacted RHB Brea to report the theft of a moisture/density gauge: CPN, MC-1, serial #MD40507409 (Cs-137, 0.370 Giga-Becquerels, Am-241, 1.85 Giga-Becquerels). The gauge had been in the back of a sport-utility-vehicle (SUV) (Subaru Crosstrek) parked in the front of an apartment building in Woodland Hills, CA, in the early morning hours prior to leaving for the temporary work site. The vehicle had been broken into by breaking the left rear window and removing the radioactive gauge from the vehicle. The Authorized User who discovered the missing radioactive gauge at approximately 0730 PDT on July 11, 2022, [redacted], notified the RSO and then notified the Los Angeles Police Department, who completed a police theft report. A copy of the theft report has been forwarded to the RHB Brea office to be included as part of this report. The RSO will contact local newspapers in an attempt to retrieve the stolen radioactive gauge, as well as notifying local servicing vendors of radioactive gauges to be alert for the serial number of the stolen gauge in case it turns up for service. The investigation will continue to determine if the radioactive gauge can be recovered."

CA 5010 Number 071122

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.

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following information was provided via email:

"On July 12, 2022, the licensee notified the Agency that around 1230 pm, a Humboldt 5001EZ Moisture Density Gauge containing a 40 milliCurie Americium-241 source and a 10 milliCurie Cesium-137 source was stolen out of the back of a company truck. The licensee reported that the technician returned to the site office, he unlocked the moisture density gauge transit case. He then got distracted and went into the office. When he went back outside the case was still chained to the truck but when he opened the case the gauge was missing. The gauge was unlocked. LLE [Local Law Enforcement] was notified. Additional information will be provided as it is received in accordance with SA-300."

PART 21 REPORT - POTENTIAL PREMATURE FAILURES OF VALCOR COIL SHELL ASSEMBLIES

The following is a synopsis of information received via facsimile:

Valcor Engineering Corporation (VEC) was notified via a letter dated 5/19/2022 that Catawba Nuclear Station (CNS) discovered two failed Coil Shell Assemblies, part number V52653-6040-7, which were removed from V70900-39-3-1 Solenoid Valves and returned to VEC for evaluation. VEC has not concluded this is a reportable condition in accordance with 10 CFR 21.22(d) and requires additional time to complete testing and evaluation.

VEC is submitting this 60-day Interim Report Notification per 10 CFR 21.21(a)(2).

VEC will complete the evaluation and provide a determination of reportability in accordance with Part 21 no later than 09/12/2022.

Currently, Catawba Nuclear Station is the only affected facility.
