Inspection Items: Radiation Work Permits and Supporting Documentation Inspection Dates: June 4,2019 Inspectors: Ryan Johnson, Utah Division Waste Management and Radiation Control (DWMRC) Personnel Contacted: Garrin Palmer, Radiation Safety Technician (RST) Justin Perkins, RST Carlos Collins, Operations Goveming Documents:o UACR313-15r Radioactive Materials License (RML) UT1900479o Applicable Mill procedures and manuals Openins Meetine Energy Fuels Resources: Justin Perkins (RST) Utah DWMRC: Ryan Johnson (Health Physics lnspector) Madi Poston-Brown (NRC Inspector) During the opening meeting, the inspector discussed the inspection items and documentation to be reviewed during the inspection. The Inspector also explained that the NRC Inspector was doing an accompaniment and an evaluation ofthe Inspector as part ofan Integrated Materials Performance Evaluation Program (IMPEP) audit of the State of Utah's Radiation Program. The Mill was not recovering uranium at the time ofthe inspection but was recovering vanadium from its process liquids that are stored in the tailing impoundments. The Mill staffreminded the inspectors of the safety requirements for the Mill.

The following discussion provides more detail ofthe specific items reviewed. Item l. Documentafion Review: The inspector reviewed radiation work permits (RWPs) from the beginning of2018 to present. The Inspector also reviewed dosimetery records from2018. Observations: The DWMRC inspector observed: r The Mill's RWPs were appropriately filled out and contained the following information: o A unique identification number;o The date the RWP was issued; o A description ofthe work to be done; o The location where the work is to be done; o Identified the persormel working on the job being done and how much time they were working on the specific job assignment; o The estimated time that it would take to do the job; o The personal protective equipment (PPE) requirements for the job; o The radiological and other occupational monitoring requiranents for the job; o The radiation technician observations and surveillance ofthe job (when applicable); ando The RSO's signature indicated that he reviewed everything associated with the work that was done under the RWP. o Other documents attached to the RWPs included: o The Mill's Safe Work permits (SWPs), which document occupational safety concems; o The Mill's Confined Space Work permits (when applicable);o Lock ouVtag out information (whan applicable);o Breathing Zone air sample results (when applicable);o Bioassay results ofpersonnel working on the RWP (when applicable); ando Photographs ofwork being done (i.e. Sequoyah Fuels project). o The Mill's dosimetry documentation for the calendar year of 20 I 8 included: o Quarterly reports from the optically stimulated luminescence (OSL) badges that the Mill used for employee occupational gamma radiation exposure;o The daily RST inspection of the dosimetry boards to identify missing OSL badges; ando The dosimetry logbook that is used to document what happened to the missing OSL badges (i.e. The ernployee took the OSL badge home, left the OSL badge in their offrce or locker, or lost their OSL badge); o Other documentation associated with dosimetry included;o The "Employee Exposure to Airbome Radionuclides" tracking form, the Mill employee's fill out to document which areas of the Mill each employee was working in and how long. (This form is used in correlation with air monitoring to assigrr the appropriate derived air concentration (DAC) values for the use ofcalculating each employee Total Effective Dose Equivalent (TEDE) value.);o The computer spreadsheet that is used to calculate the amual TEDE for each employee; ando An example of the letter that the Mill gives each employee documenting what their occupational exposure was from the previous calendar year. o All forms that were observed were leeible and most were comDlete. 2 of Page 4 CluseNvmjohrson\Downloads\Inspection Repon RADMODRWP 6-4-201 9-pg.docx Deficiencies: A few of the RWPs were missing the respirator technician's initials. Item 2. Employee Interviews: While reviewing the dosimetry logbook, the Inspector noticed that one employee had lost his OSL badge twice. The inspector asked to interview this employee. After the interview with the employee, he Inspector asked follow-up questions with Ganin Palmer, one of the Mill's RSTs. Discussion Points: The DWMRC inspector discussed with the Mill employee: o How the OSL badges were lost; o How employee informed the Mill's radiation staffthat he lost his dosimetry as soon as he noticed it was gone; r The Mill radiation safety staff gave him a new OSL badge after he reported it missing; and . He was told to wear his dosimetry inside his coveralls to reduce the chances oflosing his dosimetry in the future. Discussion Points: The DWMRC inspector discussed with the Mill RST: o The Mill has spare (aka "blank") OSL badges and they assigr Mill personnel who lose their OSL badges a new badge; and/or . Depending on the situation, to account for the lost badge, the Radiation Safety Staffwill assign the Mll personnel who lost their OSL badge the highest dose received by a coworker of the same work crew that they work with. In addition, the lnspector also discussed with the RST how an RWP request is reviewed: o Each RWP request is different but it could take up to 2 hours to review and RWP; o The RWP process begins when a supervisor requests an RWP; o Ths Radiation Safety Staffgoes out to thejob location and determines: o If an RWP is required; o What type ofPPE will be needed; o What type of radiological monitoring is needed; and o What other safety issues are present. o The Radiation and Occupational Safety Staffwill then fill out the necessary paperwork: o The RWP;o The SWP; and when applicable o Confined Entry Permits; and o Lockout/Tag out fotms. o After the RWP is completed the RSO reviews the RWPs for completeness. Deficiencies: None Item 3. Mill Tour: The Inspector walked through the restricted area on a general site tour. The tour included the ore pad, the new decontamination (decon) pad, the mill, the tailing impoundments, solvent the extraction building and the altemate feed circuit. Observations: The DWMRC inspector also observed: o The product yard containing full yellowcake (uranium) and black-flake (vanadium) drums; 3 of Page 4 C:\Users\nnjohnson\Downloads\lnspection Report RADMOD-RWP 6-4-2019-pg docx Alternate feed and ore being stockpiled on the ore pad; OSL badges were appropriately being wom and used by all observed employees at the Mill; OSL badges are properly being stored; Mill personnel were wearing appropriate PPE; The test pad on tailing impoundment #2 had "green" vegetation on it; and The Vanadium Circuit was operating during this inspection.
