X-energy LLC

X-energy develops Generation IV high-temperature gas-cooled nuclear reactors and advanced TRISO fuel to power them. The Xe-100 reactor design eliminates reliance on active safety systems by using physics-based passive safety through negative temperature coefficients and passive heat dissipation. The company's TRISO-X fuel can withstand extreme temperatures well beyond conventional nuclear fuels, enabling safer, more reliable nuclear power generation. X-energy delivers next-generation carbon-free energy by reinventing nuclear power for a cleaner planet. The company's core competencies in HTGR design and high-temperature fuel design create a unique combination applicable to nuclear thermal propulsion for space exploration. X-energy's reactor technology provides zero-emission base-load power that is scalable, locatable anywhere, and can operate independently or complement renewable energy sources to meet rising global energy demand while significantly reducing carbon emissions.
