AGREEMENT STATE REPORT - FIXED GAUGE INADVERTENTLY DISCARDED

The following report was received from the state of Kentucky via email:

"A Berthold fixed gauging device containing 16 milli-Curies of Cs-137 was out of service and scheduled for replacement when it was inappropriately removed from a belt line by a maintenance worker and thrown in a scrap metal hopper for later recycling on May 13, 2022. The licensee conducted scheduled 6 month physical inventory on June 1, 2022 and discovered a gauge was missing from the belt line where it had been installed. Carmeuse personnel conducted a search of the premises and discovered the gauge in scrap metal hopper under additional scrap metal and approximately 10 inches of gravel. The licensee reported the material contained in the hopper is placed there using equipment (e.g. forklifts, etc.). The licensee removed the device from scrap the metal bin and conducted radiation surveys. Reported exposure rates approximately were 30 mR/hr on contact. The gauge was placed in a steel cabinet for storage with reported exposure rates of less-than 1 mR/hr on exterior. All was work performed without notification to or consultation with [Radiation Health Branch] RHB. The licensee indicated the metal cabinet is located in a warehouse on premises, but made no mention of security, access control, posting, relationship to occupied spaces, etc. The licensee reported to RHB in written response that 'device was rusted and shutter was not reliable' which was itself reportable. No mention was made of lock out/tag out, position of shutter mechanism, condition of labels, presence of posting, training of worker who performed removal work, etc. A reactive inspection planned for June 8, 2022."

EN Revision Text: PARTIAL LOSS OF POWER TO RPS DURING MAINTENANCE

The following information was provided by the licensee via email:

"During thermography of a reactor protection system (RPS) distribution panel, a circuit breaker (RPS-CB-7B) was inadvertently opened. This resulted in a partial loss of power to RPS Division B, which caused containment isolations to occur in multiple systems (Reactor Water Clean Up, Equipment Drains Radioactive, Floor Drains Radioactive, Reactor Recirculation, and Traversing lncore Probe). Specifically, RWCU-V-1, FDR-V-3, EDR-V-19, RRC-V-19, and TIP-V-15 all closed. All actuations occurred as designed upon the partial loss of RPS power.

"This event is being reported pursuant to 10 CFR 50.72(b)(3)(iv)(A) due to an unplanned valid actuation of a system pursuant to 10 CFR 50.72(b)(3)(iv)(B)(2). Additionally, this is being reported pursuant to 10 CFR 50.72 (b)(3)(xiii) for a major loss of emergency assessment capability due to the inability to assess primary containment identified and unidentified leakage rates.

"Emergency assessment capability was restored at 1008 PDT upon system restoration."

The NRC resident was notified by the licensee.
