I. Discussion

On December 31, 2025, SMR, LLC, on behalf of Palisades SMR, LLC, a wholly-owned subsidiary of Holtec International (collectively, Holtec), filed with the NRC, the first part (Part 1) of a phased construction permit application for a utilization facility 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.” Part 1 of the application includes a LWA request pursuant to 10 CFR 50.10(d), “Request for limited work authorization”; three exemption requests; and a comprehensive environmental report (ER). In its LWA request, Holtec seeks NRC approval to conduct certain early construction activities of a dual-unit SMR-300 plant at the PEC in Covert, Michigan. Holtec also states that the comprehensive ER addresses the environmental impacts associated with LWA activities (including the requested exemptions), the remainder of construction to complete the plant, and plant operations. Holtec submitted Part 1 of its application as part of a phased application approach for a construction permit for a utilization facility, as described in 10 CFR 2.101(a)(9) and 10 CFR 2.600(d).

On February 27, 2026, the NRC issued a Federal Register notice (91 FR 9892) stating that the NRC staff accepted Part 1 of the phased construction permit application for docketing and will perform a detailed technical review. These weekly notices of receipt and availability of the application are being provided in accordance with the requirements in 10 CFR 50.43(a)(3).
