Home — TRISO-X: TRISO Fuel

X-energy

X-energy is a nuclear reactor & fuel design engineering company. We develop Generation IV high-temp gas cooled nuclear reactors & the TRISO-X fuel to power them.

Our Technology

Xe-100

Our Reactors

Our reactors do not rely on any active systems, electrical power or human actions to ensure safety i.e., the reactor will shut down using passive means (negative temperature coefficient) and heat can be dissipated through passive means (as a result of the low power density).

TRISO-X

Our Fuel

Advanced Reactors should provide simple, safe operation and at no additional cost. Our TRISO-X Fuel does just that. It can withstand temperatures about four times greater than conventional nuclear fuel, and it cannot melt
