RMINSPECTION REPORT
Inspection Module: RADMOD-PEM: Surveys/Posting/Exit Monitoring Inspection Location: Energy Fuels - White Mesa Uranium Mill, Blanding Utah.
Inspection Items: Radiological Postings, Routine Surveys, Employee Exit Monitoring and General License
Inspection Date: September 19 & 20, 2022 Inspectors: Ryan Johnson, Utah Division of Waste Management and Radiation Control (DWMRC) Tim Butler, DWMRC Personnel Contacted: Garrin Palmer, Radiation Safety Officer (RSO)
Governing Documents:
• UAC R313-15
• Radioactive Materials License (RML) UT1900479
• Applicable Mill procedures and manuals Opening Meeting Energy Fuels Resources: Garrin Palmer (RSO) Utah DWMRC: Ryan Johnson (Health Physics Inspector) Tim Butler (Health Physics Inspector)
During the opening meeting, the inspectors discussed the inspection items for the inspection. The Mill staff reminded the inspector of the safety requirements for the Mill. Mill is processing Calcine alternate feed material. DWMRC Meters Used Model Serial Number Calibration Due Date Dose Rate Fluke 451P 988 11/20/2022
Inspection Summary The inspection consisted of:
• Observing radiological postings around the Mill;
• Observing Mill personnel perform exit surveys:
• Reviewing documentation of: o Weekly Alpha surveys;
o Exit Monitoring; and
• Taking dose rate measurements around the Mill.
The following discussion provides more detail of each inspection items. Item 1. Radiological Postings:

Observations: During the Mill Tour the inspector observed the following posted areas:
Posting Locations Observed Postings Observed Dose Rates Yellowcake Storage Area Caution Radiation Area 75µR Laboratory Caution Radioactive Materials 27 µR
Laboratory Sample Storage (aka Balance) Room Caution Radiation Area 79 µR
Doors leading to the restricted area from the Administration

South Dryer Caution Radiation Area Caution Airborne Area 180-250 µR
North Dryer Caution Radiation Area Caution Airborne Area 130 µR
Silmet Storage Location Caution Radiation Area 700-2,000 µR
Tank #5 Caution Radiation Area 2,500 µR
CCD Fixed Gauges Caution Radioactive Materials 80-256 µR
Perimeter fence Caution Radiation Area Not Measured
Perimeter gates Any Area within this Mill May

Ore Pad No Posting 35-500 µR
Solvent Extraction Building No Posting 27 µR
Note: Due to no uranium production at the time of the inspection there are fewer posted areas in the Mill.
Deficiencies: None Item 2. Exit Surveys: The Inspector observed employees survey themselves out of the restricted area and checked the alpha meter used.
Observations: The Mill uses Alpha scintillators for exit surveys. The Inspector checked the settings of the survey instruments and found that they were set properly. Meters are calibrated annually. The Mill
personnel that were observed performing exit surveys, did the surveys appropriately. The Mill’s RSTs also perform random checks on exit surveys.

Item 3. Radiological Surveys and Monitoring: The Inspector reviewed the weekly surveys done around the Mill.
Observations: The Inspector reviewed the radiological monitoring documentation performed at the Mill site. The documentation indicated that:
• All areas of the Mill are being survey for radiological conditions;
• Surveys indicate that the Mill is being maintained within regulatory radiological parameters
• Documentation is legible, complete and using appropriate units; and
• “Clean” areas are being maintained.

Tim Butler did a General License inspection on Energy Fuels General License #G3-250. Energy Fuels has eleven fixed gauges at the Mill. During this inspection the following was observed:
• A total of 9 of the 11 gauges were checked during this inspection;
• Labels were intact and legible;
• Leak Tests were being done at the proper frequency;
• Shutter checks were being done at the proper frequency;
• Gauges appeared to be in good condition;
• Radiological dose rates near the gauges were within regulatory limits; and
• All of the gauges are in the restricted area of the Mill and are secure.
