RE: Health Physics Inspection RADMOD-PEM-0I
Radioactive Material License Number UT 1900479
Dear Ms. Weinel:
On October 20,2015, an inspection was conducted at your facility by representatives of the Division of
Waste Management and Radiation Control. Observations from the inspection were discussed at the
closeout meeting with White Mesa Uranium Mill staff.
The inspection was an examination of the activities conducted at your facility as they relate to
compliance with the Utah Radiation Control Rules, the license conditions of the RML No. UTI900479
and federal regulations. The inspection consisted of an examination of representative records,
interviews of personnel and observations by the inspector.
Enclosed is the inspection report for your records. The Division considers this inspection closed. The
Division would like to thank the Mill staff for their cooperation during this inspection.
If you have any questions, please call Ryan Johnson at [phone]-
Sincerely,
Scott T. Anderson, Director

During the opening meeting the inspectors discussed the inspection items fq-r the inspection. The
inspectors also discussed an incident involving a roll-offcontainer that was released from the Mill and an
upcoming site tour for an NRC training course. The Mill was not in operation during the inspection except
for the alternate feed circuit. The Mill saffreminded the inspector of the safety requircments for the Mill.
Insnection Summan
The inspection consisted of:o Observing radiological postings around the Mill;o Observing Mill personnel perform exit surveys:
r Reviewing documentation of:o Weekly Alpha surveys;o Monthly Beta-Gamma surveys;o Daily Efficiency meter checks; ando Taking dose rate measurements and large area swipes 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:
The lnspector also observed that the postings were placed in visible areas and they were legible. However,
the inspector did observe that many of the postings were starting to fade.
Deficiencies: None
Item 2. Exit Suneys: The Inspector observed four employees survey themselves out of the resfficted area
and checked the alpha meters used.
Observations: While observing the employees suwey themselves out of the area the Inspector observed
that they surveyed themselves too fast. The lnspector also checked the settings of the survey instruments
and found that they were set properly. The inspector also reviewed the Daily Effrciency check form and
found not deficiencies.
Deficiencies: None
Item 3. Alpha and Gamma Suneys: During the Mill tour the Inspector observed general dose rates
around the Mill site and collected swipe samples.

During the closeout meeting the inspector discussed with the RSO and Mill Manager that:l. Some of the postings were starting to fade;2. The Millemployees wene surveying themselves to fast; and3. The inspector measured 200 dpm/|00 cm2 offa table in the control room. The Inspector noted that
it was not violation because it was found in an area not used for eating but reminded the RSO and
Mill Manager that it is a good ALARA practice to keep the contamination levels down inside the
Mill.
