NUCLEAR REGULATORY COMMISSION
[Docket No. 70-7004; NRC-2024-0145]
American Centrifuge Operating, LLC; American Centrifuge Plant;
Environmental Assessment and Finding of No Significant Impact
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering an
amendment of Special Nuclear Material (SNM) License No. SNM-2011,
issued on April 13, 2007, to American Centrifuge Operating, LLC (ACO)
for the operation of the American Centrifuge Plant (ACP). This proposed
amendment would increase ACO's licensed material possession limits
under the high-assay, low-enriched uranium (HALEU) demonstration and
operations program to support production of approximately 1,400
kilograms (kg) of HALEU in the form of uranium hexafluoride
(UF6). For this proposed action, the NRC staff is issuing an
environmental assessment (EA) and finding of no significant impact
(FONSI).
DATES: The EA and FONSI referenced in this document are available on
September 19, 2024.

SUPPLEMENTARY INFORMATION:
I. Introduction
The NRC is considering an amendment of ACO's Special Nuclear
Materials License No. SNM-2011, which authorized the operation of the
HALEU cascade at the ACP in Pike County, Ohio in June 2021. If
approved, the amendment would increase ACO's licensed material
possession limits to support the production of HALEU UF6
from 600 kg to approximately 1,400 kg and would allow ACO to store
approximately 1,400 kg of HALEU UF6 at the ACP. As required
in section 51.21 of title 10 of the Code of Federal Regulations (10
CFR), ``Environmental Protection Regulations for Domestic Licensing and
Related Regulatory Functions,'' the NRC developed an EA for the
proposed license amendment to increase the possession limits for
licensed material at the ACP. Based on the results of the EA summarized
in this notice, the NRC has determined not to prepare an environmental
impact statement (EIS) for the amendment and is issuing a FONSI.
ACO is producing HALEU for the U.S. Department of Energy (DOE).
HALEU is uranium that has been enriched so that the concentration of
the fissile isotope U-235 is between 5 and 20 percent of the mass of
the uranium. The DOE established a 3-phase contract with ACO to deploy
a cascade of 16 operating centrifuges and two spare centrifuges to
demonstrate the capability to enrich uranium to the higher level. The
NRC approved the license amendment for the operation of this HALEU
cascade in June 2021. The expiration date of the current phase (phase
2) of the contract that DOE has funded is December 31, 2024. Phase 3,
involving up to three, 3-year periods of operation of the HALEU
cascade, would need Congressional appropriations and the approval of
the NRC to move forward.
II. Summary of Environmental Assessment
Description of the Proposed Action
The proposed action would increase the authorized limits for
possession of licensed material for the purpose of producing
approximately 1,400 kg of HALEU UF6 from the current HALEU
UF6 production amount of 600 kg. This amendment would be
effective until DOE's contract with ACO expires on December 31, 2024.
If ACO requests an extension of the HALEU cascade program beyond
December 31, 2024, the NRC would need to conduct a separate licensing
and environmental review for that extension.
ACO operates the HALEU cascade in a building that previously housed
the former Lead Cascade Facility, which was decommissioned in 2018. ACO
does not propose to construct new buildings, conduct ground-disturbing
activities, ship HALEU offsite, or make changes to the HALEU centrifuge
cascade design that the NRC approved in 2021.
The proposed action is in accordance with the licensee's
application dated February 13, 2023, as supplemented by letters dated
June 29, 2023, February 15, 2024, and March 7, 2024.
Need for the Proposed Action
The proposed amendment would allow ACO to continue demonstrating
the capability to enrich uranium-235 up to a level necessary to produce
HALEU. ACO is under contract with DOE to enrich uranium and produce
HALEU using the 16-centrifuge enrichment cascade constructed for this
purpose.
Environmental Impacts of the Proposed Action
The NRC staff assessed the potential environmental impacts from the
increase in possession limits on land use; historic and cultural
resources; visual and scenic resources; climatology, meteorology and
air quality; geology and soils; water resources; ecological resources;
socioeconomics; noise; traffic and transportation; public and
occupational health and safety; and waste management. The NRC staff
determined that the proposed action would not affect most resource
areas and would not have significant impacts on air quality,
transportation, occupational health and safety, and waste management.
ACO would not make changes to the enrichment processes or to the
outside portions of buildings. All HALEU produced would be stored
onsite. All enrichment activities would continue to take place indoors,
resulting in no changes to noise levels. Because operations would
continue entirely inside buildings, including storage of additional
enriched UF6 depleted UF6, and wastes, and
because the current rate of HALEU production would not change, there
would be no change to potential impacts on public health and safety.
Because additional employees would not be required for the proposed
action, there would be no change to socioeconomic impacts already
assessed. The NRC staff further concluded in the EA that the potential
impacts on air quality, occupational health and safety, waste
management, and transportation are bounded by the impacts assessed in
previous NRC environmental assessments, as documented in the NRC's 2021
EA for the approval of the HALEU demonstration program.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Under the no-action alternative, the NRC would deny ACO's request and
ACO's HALEU production level would remain at 600 kg. The no-action
alternative would not permit ACO to meet the terms of DOE's contract
with ACO. The potential environmental impacts of denying the request
would be unchanged from the impacts as assessed in the NRC's 2021 EA
for the approval of the HALEU demonstration program.
Agencies and Persons Consulted
In accordance with NRC policy, on June 27, 2024, the staff
consulted with the Ohio Emergency Management Agency, Ohio Environmental
Protection Agency, and Ohio Department of Health regarding the EA and
FONSI. On July 5, 2024, the staff consulted with U.S. Environmental
Protection Agency (EPA) Region 5 regarding the EA and FONSI. In
addition, on July 5, 2024, the staff provided a courtesy notification
of the proposed action to the Ohio State Historic Preservation Office.
The NRC received no comments on the EA.
III. Finding of No Significant Impact
Based on its review of the proposed license amendment request, in
accordance with the requirements of 10 CFR part 51, the NRC staff has
determined that approving the requested license amendment to increase
the possession limits of licensed material for the HALEU
[[Page 76873]]
demonstration and operations program would not significantly affect the
quality of human environment. No significant radiological or non-
radiological impacts are expected from the proposed action. Therefore,
the NRC staff has determined that, pursuant to 10 CFR 51.31,
``Determinations based on environmental assessment,'' preparation of an
EIS is not required for the proposed action, and pursuant to 10 CFR
51.32, ``Finding of no significant impact,'' a FONSI is appropriate. In
accordance with 10 CFR 51.32(a)(4), this FONSI incorporates the EA
summarized in this notice by reference.
