II. Discussion
By letter dated March 28, 2024 (ADAMS Package Accession No.
ML24088A059), TerraPower, LLC (TerraPower) on behalf of US SFR Owner, LLC, a
wholly owned subsidiary of TerraPower, submitted to the NRC pursuant to Section 103
of the Atomic Energy Act and part 50 of title 10 of the Code of Federal Regulations (10

CFR), “Domestic Licensing of Production and Utilization Facilities,” an application for a
CP to construct a Natrium Reactor Plant, Kemmerer Power Station Unit 1, in Lincoln
County, Wyoming as part of participation in the U.S. Department of Energy’s Advanced
Reactor Demonstration Program. The Natrium Reactor Plant is an 840 megawatts
thermal, pool type, sodium-cooled fast reactor that contains a compact and simple safety
envelope and a molten salt energy storage system. This submission initiated the NRC’s
proposed action of determining whether to grant the CP. The application was
supplemented on May 2, 2024 (ADAMS Accession Nos. ML24123A242, ML24123A243)
and May 9, 2024 (ADAMS Accession No. ML24130A181). A notice of receipt and
availability of the application, was published in the Federal Register (FR) on
May 14, 2024 (89 FR 42004).
The NRC staff determined that TerraPower submitted an application in
accordance with 10 CFR part 50, and that the application is acceptable for docketing
under Docket No. 50-0613. The NRC sent a letter of acceptance and docketing to
TerraPower on May 21, 2024 (ADAMS Accession No. ML24135A109). A notice of
acceptance for docketing of the application and notice of hearing were published in the
FR on June 4, 2024 (89 FR 47997). These notices are available on the Federal
rulemaking website (https://www.regulations.gov) by searching for Docket ID NRC-20240078.
III. Request for Comment
This notice informs the public of the NRC’s intent to conduct environmental
scoping and prepare an EIS related to the CP application for Kemmerer Power Station
Unit 1 and to provide the public an opportunity to participate in the environmental
scoping process, in accordance with 10 CFR 51.29 “Scoping-environmental impact
statement and supplement to environmental impact statement,” and 10 CFR 51.116
“Notice of intent.”
The regulations in 36 CFR 800.8, “Coordination with the National Environmental
Policy Act,” allow agencies to use their National Environmental Policy Act of 1969

(42 U.S.C. 4321, et seq.) (NEPA) process to fulfill the requirements of Section 106 of the
National Historic Preservation Act of 1966 (54 U.S.C. 300101, et seq.) (NHPA).
Therefore, pursuant to 36 CFR 800.8(c), the NRC intends to use its process and
documentation required for the preparation of the EIS on the proposed action to comply
with Section 106 of the NHPA in lieu of the procedures set forth at 36 CFR 800.3
through 800.6.
In accordance with 10 CFR 51.50(a), TerraPower submitted an ER as part of the
CP application. The ER was prepared pursuant to 10 CFR part 51 and is publicly
available at ADAMS Accession No. ML24088A072. The ER will also be available for
viewing at https://www.nrc.gov/reactors/new-reactors/advanced/who-were-workingwith/applicant-projects/terrapower.html. In addition, the ER is available for public review
at the Lincoln County Library, 519 Emerald Street, Kemmerer, WY 83101.
The NRC intends to gather the information necessary to prepare an EIS related
to the CP application for the Kemmerer Power Station Unit 1. The NRC is required by
10 CFR 51.20(b) to prepare an EIS in connection with the issuance of a CP for a power
reactor. This notice is being published in accordance with NEPA and the NRC’s
regulations at 10 CFR part 51.
The EIS will evaluate the environmental impacts of construction, operation, and
decommissioning of the Kemmerer Power Station Unit 1, and reasonable alternatives
thereto. Possible alternatives to the proposed action include the no action alternative
and alternative sites.
As part of its environmental review, the NRC will first conduct a scoping process
and, as soon as practicable thereafter, will prepare a draft EIS for public comment.
Participation in this scoping process by members of the public and local, State, Tribal,
and Federal government agencies is encouraged. The scoping process for the draft EIS
will be used to accomplish the following:

a.

Define the proposed action that is to be the subject of the EIS;

b.

Determine the scope of the EIS and identify the significant issues to be

analyzed in depth;
c.

Identify and eliminate from detailed study those issues that are peripheral

or are not significant or that have been covered by prior environmental review;
d.

Identify any environmental assessments and other ElSs that are being or

will be prepared that are related to, but are not part of, the scope of the EIS under
consideration;
e.

Identify other environmental review and consultation requirements related

to the proposed action;
f.

Indicate the relationship between the timing of the preparation of the

environmental analyses and the NRC’s tentative planning and decision-making schedule;
g.

Identify any cooperating agencies and, as appropriate, allocate

assignments for preparation and schedules for completing the EIS to the NRC and any
cooperating agencies; and
h.

Describe how the EIS will be prepared, including any contractor

assistance to be used.
The NRC invites the following entities to participate in scoping:

a.

The applicant, US SFR Owner, LLC.;

b.

Any Federal agency that has jurisdiction by law or special expertise with

respect to any environmental impact involved or that is authorized to develop and enforce
relevant environmental standards;
c.

Affected State and local government agencies, including those authorized

to develop and enforce relevant environmental standards;
d.

Any affected Indian Tribe;

e.

Any person who requests or has requested an opportunity to participate in

the scoping process; and

f.

Any person who has petitioned or intends to petition for leave to intervene

under 10 CFR 2.309.
IV. Public Scoping Meeting
In accordance with 10 CFR 51.26(b), the scoping process for an EIS may include
a public scoping meeting to help identify significant issues related to the proposed action
and to determine the scope of issues to be addressed in the EIS.
The NRC is planning to conduct a public scoping meeting for the Kemmerer
Power Station Unit 1 EIS. The meeting is currently expected to be held on July 16, 2024.
Meeting details will be available by June 25, 2024, at https://www.nrc.gov/reactors/newreactors/advanced/who-were-working-with/applicant-projects/terrapower.html or at the
NRC’s Public Meeting Schedule website at https://www.nrc.gov/pmns/mtg. A court
reporter will transcribe all comments received during the public meeting. To be
considered, comments must be provided either at the transcribed public meeting or in
writing, as discussed in the “ADDRESSES” section of this document. Please contact
Patricia Vokoun no later than July 6, 2024, if accommodations or special equipment is
needed to participate or to provide comments, so that the NRC staff can determine
whether the request can be accommodated.
The public scoping meeting will include: (1) an overview by the NRC staff of the
safety and environmental review processes, the proposed scope of the EIS, and the
proposed review schedule; and (2) the opportunity for interested government agencies,
organizations, and individuals to submit comments or suggestions on environmental
issues or the proposed scope of the Kemmerer Power Station Unit 1 EIS.
Participation in the scoping process for the Kemmerer Power Station Unit 1 EIS
does not entitle participants to become parties to the proceeding to which the EIS

relates. Matters related to participation in any hearing are outside the scope of matters to
be discussed at this public meeting.
