America's First "Large Reactor in a Chemical Plant" Clears the Hurdle: X-energy Xe-100 Ushers in the Conclusion of Safety Review and a Key Springboard to Commercialization
In the global race to industrialize advanced nuclear energy technologies, the high-temperature gas-cooled reactor is reaching a milestone. In late October 2026, the U.S. Nuclear Regulatory Commission (NRC) formally issued the Final Safety Evaluation Report (FSER) for the construction permit application of the Long Mott Generating Station, proposed to be built at Dow Chemical's Seadrift site along the Texas Gulf Coast. This means that the Xe-100 high-temperature gas-cooled reactor, developed by X-energy with an installed capacity of 320 megawatts electric, has successfully passed the most central safety examination at the U.S. nuclear regulatory level, clearing...
