On New Year’s Eve, Holtec International submitted Part 1 of a construction permit application to the Nuclear Regulatory Commission seeking a limited work authorization (LWA) to begin construction of a two-unit SMR-300 plant at the company’s site in Covert, Mich.

Named Pioneer-1 and -2, the twin 340-MWe pressurized water reactors would join the 777-MWe Palisades PWR that began operating in 1971, shut down in 2022, and is expected to reconnect to the grid—slightly delayed—early this year. According to Holtec’s application documents, Part 2 of its construction permit will be filed no later than mid-2027.
