Holtec SMR-300 picked for revived Utah Green River nuclear project
A newly formed joint venture between Blue Castle Holdings and Fulcrum Point Holdings will deploy Holtec International's SMR-300 pressurized-water reactors at the long-dormant Blue Castle site in Green River, Utah, the partners said in early June, reviving a project that had spent 19 years collecting environmental, seismic, and groundwater data. The plan calls for two to four SMR-300 units producing a combined 600 to 1,200 MW, and Holtec's air-cooling design is well suited to the arid Emery County site where water is scarce. The revival falls under Utah's 'Operation Gigawatt' clean-energy initiative.
