Re: Follow-up to Discussion Regarding Licensee-to-Licensee Transfer of Source Material at
Energy Fuels Resources (USA) Inc.'s ("EFRI's") White Mesa Mill, State of Utah
Radioactive Materials License No. UT1900479
Dear Mr. Anderson:
This letter is a follow-up to discussions between EFRI and the Division of Waste Management and
Radiation Control ("DWMRC") regarding EFRI's intent to receive yellowcake slurry from Energy
Fuels' Nichols Ranch In-Situ Recovery ("ISR") Project ("Nichols Ranch") located in Wyoming (U.S.
Nuclear Regulatory Commission ("NRC") License No. SUA-1597 held by EFRI's affiliate Uranerz
Energy Corporation) for final processing at the White Mesa Mill (the "Mill"). Under the intended
activity, yellowcake slurry will be transferred from Nichols Ranch to the Mill pursuant to 10 CFR
40.51 and the Mill's License as a licensee-to-licensee transfer of source material. The purpose of this
letter is to advise DWMRC of this activity and to provide details on the mode of transportation, receipt
and processing at the Mill, and disposal of 1 le.(2) byproduct material, as described below.
Transportation
The Nichols Ranch processing facility is located in the Pumpkin Buttes Mining District of the Powder
River Basin in Johnson and Campbell Counties, which is approximately 700 miles by road to the Mill.
Yellowcake slurry will be transported from Nichols Ranch to the Mill by truck and trailer using a
Uranium Slurry Hauling System (U.S. Pat. No. 4,395,052). The trucks will travel on State roads and
interstate highways, using the same or similar routes as the trucks that currently transport 1 le.(2)
byproduct material from Nichols Ranch for disposal at the Mill under the Mill's existing License
condition 10.5.

Each shipment of yellowcake slurry is expected to contain approximately 20,000 to 24,000 pounds of
yellowcake (as uranium oxide or U3O8 equivalent). As part of the intended activity, the Mill would
receive approximately 15 to 25 shipments of yellowcake slurry per year, which is equivalent to
approximately 300,000 to 600,000 pounds of dried, packaged yellowcake (as U308 equivalent) per
year.
The Mill is currently licensed to produce up to 4380 tons (approximately 8,000,000 pounds) of
yellowcake per year. An average truck shipment of dried yellowcake from the Mill, typically contains
40 drums or up to 19 tons of yellowcake (as U3O8 equivalent). At full operation, the Mill will ship
approximately 210 truckloads of dried yellowcake product to the conversion facility per year. At
recent operation levels of approximately one million pounds of yellowcake (as U3O8 equivalent) per
year, the Mill has shipped approximately 26 truckloads of dried yellowcake per year.
The number of trucks (15 to 25 per year) associated with transporting the yellowcake slurry will be
much less (approximately 85 times less) than the number of trucks required to transport the quantity of
ore needed to produce the same mass of yellowcake slurry. Further, the number of trucks (8 to 16 per
year) required to transport the dried, packaged yellowcake from the Mill would be the same as
required to transport dried yellowcake produced from processing natural ores or any other feed
material from the Mill.
Existing regulations (e.g., 10 CFR 71 and 49 CFR 171-189) regulate the shipment of source material,
including the shipment of yellowcake slurry between Nichols Ranch and the Mill. The NRC has
concluded that "The effects of accidents involving wet yellowcake would be considerably less than
those involving yellowcake dust.... because the material would be incapable of becoming airborne as
dry dust.... Sufficient statistical data are not available for a quantitative analysis of the consequences
of such an accident. However, the consequences would likely be considerably lower than those
estimated for the shipment of dry concentrate." NUREG-1508, Final Environmental Impact Statement
to Construct and Operate the Crownpoint Uranium Solution Mining Project, Crownpoint, New
Mexico page 4-70 (see also NUREG-0706, Final Generic Environmental Impact Statement on
Uranium Mining page 7-11, and NUREG-6733, A Baseline Risk-Informed, Performance-Based
Approach for In Situ Leach Uranium Extraction Licensees pages 4-55 and 5-6, for similar statements
by the NRC).
As the number of slurry trucks (15 to 25 per year) combined with the number of additional yellowcake
product trucks (8 to 16 per year for a total of 23 to 41 per year) required to transport the produced
yellowcake product to the conversion facility, combined with the current operations of approximately
26 truckloads of dried yellowcake per year, will be well within the number of yellowcake product
trucks contemplated for the Mill at full operation of approximately 210, the transportation of
yellowcake slurry to the Mill and resulting yellowcake product from the Mill will fall well within the
safety and environmental review envelope previously analyzed for the Mill.

Receipt
The first paragraph and Conditions 6, 7, and 8 of the Mill License allow EFRI to "transfer, receive,
possess and use" "Natural Uranium" in "Any" form with an "Unlimited" quantity at any one time.
Receipt of yellowcake slurry would be a licensee-to-licensee transfer of source material to the Mill
under 10 CFR 40.51(5) because the Mill is "authorized to receive such source or byproduct material"
under terms of the Mill License, which is "a specific license or a general license or their equivalents
issued by the Commission or an Agreement State;" as required by that regulation.
Processing
Upon receipt, EFRI plans to feed yellowcake slurry directly into the Mill at the Precipitation and
Thickening stage of the process circuit. Should the yellowcake slurry need to be stored at the Mill
prior to processing, it would remain in the shipment containers (i.e., slurry tanks) and be stored on the
Ore Storage Pad. Once the yellowcake slurry is added to the process circuit, final processing will not
result in any changes from the process conditions or configurations that are already in use at the Mill.
Further, the processing of yellowcake slurry from Nichols Ranch, which will result in a maximum
production amount of approximately 600,000 pounds of yellowcake per year, will not cause the Mill
to exceed the License production limit of 4380 tons (approximately 8,000,000 pounds) of yellowcake
per year.
Disposal
As the yellowcake slurry will be transferred and received at the Mill as a licensee-to-licensee transfer
of source material for further processing into dried, packaged yellowcake, the wastes associated with
processing of the yellowcake slurry are considered 1 le.(2) byproduct material and will be disposed of
in the Mill's tailings cells. The NRC has concluded that source material may be transferred from one
licensee to another as part of the uranium milling process and that the wastes generated at each
licensed facility qualify as 1 le.(2) byproduct material.1 .
1 The NRC has concluded that drying and packaging yellowcake in these types of circumstances is uranium
milling and that the resulting wastes are 1 le.(2) byproduct material. In Staff Requirements - SECY—02—0095
- Applicability of Section lle.(2) of the Atomic Energy Act to Material at the Sequoyah Fuels Corporation
Uranium Conversion Facility, a copy of which has been provided to DRC in the past, NRC concluded that
wastes generated at the front end of the Sequoyah Fuels Corporation conversion facility ("SFC") that resulted
from the further concentration and purification of yellowcake that it had received from uranium mills can be
classified as 1 le.(2) byproduct material. In that decision, the Commission accepted NRC Staff's position that
"The staff has not found it necessary to label the feed for each step of the milling process as "ore" as the basis
for classifying the waste from that step as 1 le.(2) byproduct material. When yellowcake underwent additional
concentration at the front end of SFC, it was a continuation of uranium milling, i.e., another step of the milling
process. Thus, that part of the processing at a conversion facility fulfills the "extraction or concentration" terms
of lle.(2) byproduct material" (see Policy Issue (Notation Vote) SECY-02-0095, page 3). The Nichols Ranch
facility does not have a drying and packaging circuit, and therefore must send its yellowcake slurry to the Mill
or to another licensed facility to perform this final stage of uranium milling. As indicated by NRC Staff, and

Conclusions
The yellowcake slurry can be received at the Mill as a licensee-to-licensee transfer of source material
under 10 CFR 40.51(5) and the existing Mill License. The yellowcake slurry can be fed directly into
the Mill's process circuit and processed utilizing existing equipment into dried, packaged yellowcake
with no changes to the Mill's process conditions or configurations needed. All wastes generated from
the processing of yellowcake slurry can be disposed of in the Mill's tailings cells as 1 le.(2) byproduct
material. As the processing of yellowcake slurry does not conflict with any requirements in the Mill
License and is consistent with the safety and environmental review envelope previously analyzed for
the Mill, an amendment to the License is not required.
Please let me know if you have any questions or require any further information regarding the
foregoing. You can reach me at 303-389-4132 or Kathy Weinel at 303-389-4134.

adopted by the Commission, "[the Office of the General Counsel] has advised the staff that the definitions of
uranium milling and 1 le.(2) byproduct material are process-related definitions and not restricted to a particular
location of activity nor the physical characteristic of a material" (see Policy Issue (Notation Vote) SECY-02-
0095, footnote 2). In fact, NRC Staff noted a number of circumstances where uranium mills in the past each
performed a part only of the uranium milling process and then shipped the resulting produced material or
concentrates to another licensed facility for further milling. NRC Staff noted that "[e]ach of these mills and
several others accomplished only a portion of the milling process at dispersed locations but were all licensed
operations at one time" (see Policy Issue (Notation Vote) SECY-02-0095, Attachment 5: Uranium Milling
Activities at Sequoyah Fuels Corporation, page 2). Drying and packaging the Nichols Ranch yellowcake slurry
at the Mill is therefore another step of the uranium milling process, and all wastes associated with such milling
are classified as 1 le.(2) byproduct material and can be disposed of in the Mill's tailings cells.
Sincerely,
