Xe-100
Xe-100 is X-energy's 80 MWe high-temperature gas-cooled pebble-bed reactor using TRISO fuel particles.
Each Xe-100 unit uses helium coolant at 750°C outlet temperature and helium Brayton cycle power conversion. Plants scale to 960 MWe with 12 units. X-energy has DOE ARDP funding and Amazon PPA for three units.
Why it matters now
Xe-100 advances SMR commercialization with data center hyperscaler contracts like Amazon's 2024 PPA. TRISO fuel qualification and HALEU de-risking support 2028+ deployments amid licensing reviews.
