SUPPLEMENTARY INFORMATION:
I.
Introduction Under section 2.106 of title 10 of the Code of Federal Regulations (10 CFR),
Notice of issuance, the U.S. Nuclear Regulatory Commission (NRC or the Commission) is providing notice of the issuance of Construction Permit (CP) No. CPAR-1 to US SFR Owner, LLC (USO) and issuance of the record of decision (ROD) under 10 CFR 51.102, Requirement to provide a record of decision; preparation. The CP, which is immediately effective, authorizes USO to construct a power reactor facility in Lincoln County, Wyoming, as described in the CP application. With respect to the CP application filed by TerraPower, LLC on behalf of USO, the NRC finds that the applicable standards and requirements of the Atomic Energy Act of 1954, as amended, and the Commissions regulations have been met. The NRC finds that any required notifications to other
3 agencies or bodies have been duly made and that, among other things, there is reasonable assurance that the activities authorized by the permit will be conducted in compliance with the rules and regulations of the Commission, that safety questions will be satisfactorily resolved by the completion of construction, and that, taking into consideration siting criteria, the proposed facility can be constructed and operated at the proposed location without undue risk to public health and safety, subject to the conditions listed in the CP. Furthermore, the NRC finds that the licensee, USO, is technically and financially qualified to engage in the activities authorized, and that issuance of the CP will not be inimical to the common defense and security or to the health and safety of the public. Finally, the NRC finds that the findings required by subpart A, National Environmental Policy Act - Regulations Implementing Section 102(2) of 10 CFR part 51, Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions have been made.
Accordingly, the immediately effective CP was issued on March 9, 2026.
II.
Further Information The NRC staff prepared a Safety Evaluation (SE) and Final Environmental Impact Statement (FEIS) that document its evaluation of the CP application and its findings. The Commission also issued its Memorandum and Order documenting its final decision on the uncontested hearing on March 4, 2026, which serves as the ROD in this proceeding. The NRC staff also prepared a summary of the ROD that incorporates by reference the materials contained in the FEIS. In accordance with 10 CFR 2.390, Public inspections, exemptions, requests for withholding, of the NRCs Agency Rules of Practice and Procedure, details with respect to this action, including the SE, FEIS, the summary of the ROD, and accompanying documentation included in the CP package, as well as the Commissions hearing decision, are available online in the ADAMS Public
4 Documents collection at https://www.nrc.gov/reading-rm/adams.html. From this site, persons can access the NRCs ADAMS, which provides text and image files of NRCs public documents.
