OPENING MEETING May 1, 2025@ 0945 with Thomas Brown and Curtis Kirk ofEnergySolutions. Inspector(s) discussed the aspects of the inspection and requested access to dosimetry records. ES staff agreed to accommodate the inspection. MANAGEMENT ACTIVITES: During the inspection, routine site activities were being conducted at the Clive facility. Activities included waste placement at LLRW and CWF, container receipt and unloading, container decontamination, Mixed Waste Treatment, thermal desorption, laboratory, unloading activities at both East and West railcar Rotary Facilities and various other site compliance and maintenance activities. NARRATIVE: The Inspector(s) reviewed various personnel files filed in the Health Physics Office at the Clive Administration Building. With the help of the Assistant Radiation Safety Officer (ARSO), personnel records were chosen: five (5) workers employed less than one (1) year at Clive, five (5) workers employed greater than five (5) years at Clive and fifteen (15) workers chosen randomly. Records were reviewed for the inclusion of Previous Radiation History Form, CL-RS- PR-210-F2, Hazardous Screening Certification Form, CL-RS-PR-210-F7, and Bioassay Submittal per Bioassay Monitoring Form, CL-RS-PR-221-Fl. Records were also reviewed for completion of special in-vitro bioassay monitoring required by ES procedures. The ARSO was interviewed as to any lost dosimetry incidents and any assigned dose based on bioassay results. One incident of lost dosimetry occurred during this calendar year and an assigned dose based on bioassay results. Reviewed records were complete and compliant with ES Procedures and Utah Rules. Records were also reviewed for who had exceeded the 100 mR procedural dose limit for the first half of 2024. All Semiannual TEDE Exceedance Investigation Forms, CL-RS-PR-210-F5 have been completed for these employees. The Inspector also observed the ARSO perform a lung count (in-vivo bioassay) at the site's Canberra Model 2280 Accuscan II Lung Counter. Records were reviewed pertaining to the operator's (ARSO) qualifications, calibration, daily and weekly background counts and quarterly surveillance. Field observations were made by the Inspector for proper personnel dosimetry use and proper storage of dosimetry badges. ISSUES: No discrepancies were noted during this inspection. All records were readily available and found to be complete and accurate. The lung counter and bioassay programs were administered in accordance with site procedures and state rules. CLOSEOUT MEETING: May 20, 2025 @ 1100 with Dale Thorn, Thomas Brown and Curtis Kirk ofEnergySolutions and Kevin Carney, Inva Braha and Bryan Woolf of WMRC. The inspector(s) discussed the results of the inspection with ES staff. The inspector(s) informed ES staff that there were no discrepancies found during the inspection and thanked them for their cooperation. ES staff had no comments.
