The US Nuclear Regulatory Commission (NRC) has received the first part of a construction permit application for Texas-based Holtec’s proposed project to deploy two SMR-300 small modular reactor (SMR) units at the Palisades nuclear site in Michigan.
The NRC said in a statement that the application was submitted on 31 December 2025 by SMR LLC, a subsidiary of Holtec International, for the dual-unit SMR station, called Pioneer. The submission is now available for public inspection.
