X-energy gets green light to build its first small modular nuclear reactors

Good news!

"... The Nuclear Regulatory Commission (NRC) approved the construction permit application for four of X-energy’s Xe-100 reactors at a Dow chemical plant in Texas. Each reactor will be capable of generating 80 megawatts of electricity and 200 megawatts of heat. X-energy says the approval is the first for an advanced nuclear reactor at an industrial site in the United States. ..."

"... X-energy’s Xe-100 is an 80 MWe/200 MWt high-temperature gas-cooled reactor designed to ensure safety through the passive physics of its advanced TRISO-X coated particle fuel, as well as traditional defense-in-depth systems. TRISO fuel encompasses, in one component, many barriers to the release of radionuclides, and has been described by the DOE as, “the most robust nuclear fuel on earth.” This safety profile is expected to support a 400-meter emergency planning zone, compared to 10 miles for conventional light-water reactors, enabling new generation to be safely sited closer to the point of need. ..."
