X-energy to irradiate TRISO-X fuel with MIT

29 May 2020

X-energy has reached an agreement with the Massachusetts Institute of Technology (MIT) for the Institute's Nuclear Reactor Laboratory to use its research reactor to irradiate X-energy's TRISO-X fuel. The irradiation process will provide data in support of licensing X-energy's Xe-100 and other TRISO-based reactors.

X-energy's reactors all use tri-structural isotropic (TRISO) particle fuel, a robust nuclear fuel particle. For over three years, X-energy has manufactured a proprietary version, TRISO-X, which seals uranium particles in a protective coating, eliminating the meltdown risk associated with traditional nuclear plants.

The irradiation is scheduled to occur later this year.

Currently, X-energy is the only U.S. company actively producing TRISO fuel. The company is currently engaging with the Department of Energy to further develop and design its TRISO-X fuel.
