SUPPLEMENTARY INFORMATION:
I. Introduction
Under section 2.106 of title 10 of the
Code of Federal Regulations
(10 CFR), “Notice of issuance,” the NRC is providing notice of the issuance of CP No. CPAR-3 to LME. The CP, which is immediately effective, authorizes LME to construct a power reactor facility in Calhoun County, Texas, as described in the CP application. With respect to the CP application filed by LME, the NRC found that the applicable standards and requirements of the Atomic Energy Act of 1954, as amended, and the Commission's regulations have been met. The NRC found that any required notifications to other 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 found that the licensee, LME, is technically and financially qualified to construct the facility, 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 found that issuance of the CP was in accordance with 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,” and that all applicable requirements had been satisfied.
Accordingly, the immediately effective CP was issued on November 9, 2026.
II. Further Information

In accordance with 10 CFR 2.390, “Public inspections, exemptions, requests for withholding,” of the NRC's “Agency Rules of Practice and Procedure,” details with respect to this action, including the SE and EA, and accompanying documentation included in the CP package, are available online in the ADAMS Public Documents collection at
