TRISO stands for TRi-structural ISOtropic particle fuel. Each TRISO particle is made up of a uranium, carbon and oxygen fuel kernel. The kernel is encapsulated by three layers of carbon- and ceramic-based materials that prevent the release of radioactive fission products.

0.845 mm TRISO fuel particle which has been cracked, showing multiple layers that are coating the spherical kernel. Tristructural-isotropic (TRISO) fuel is a type of micro-particle fuel.

Mar 1, 2021 · Tristructural isotropic (TRISO) particle fuel has long been used in high-temperature gas-cooled nuclear reactors, but it is seeing a resurgence as a result of other applications.

WHAT IS TRISO FUEL? TRISO stands for TRi-structural ISOtropic particle fuel. Each TRISO particle is made up of a uranium, carbon and oxygen fuel kernel. The kernel is encapsulated by three layers of carbon- and ceramic-based materials which prevent the release of radioactive fission products.

TRISO-X fuel is a proprietary version of tri-structural isotropic (TRISO) particle fuel developed by X-energy. It is a robust fuel designed to withstand high temperatures without melting and offers enhanced safety features for advanced nuclear reactors .

Nov 16, 2009 · The AGR-1 test specimens contain TRISO (Tristructural Isotropic) particle fuel with uranium oxycarbide (UCO) fuel kernels each surrounded by three coating layers that serve as mini-containment vessels to hold in radioactive fission products.

A TRi-structural ISOtropic (TRISO) particle is a Uranium bearing sphere, the size of a poppyseed, coated with special ceramic layers designed like tiny pressure vessels. The layers contain fission products inside and ensure mechanical and chemical …

TRISO Fuel Quality and Performance • Main goal: Retain fission products in fuel • Limit coating layer failure • Minimize radionuclide transport through intact coatings • Coatings are engineered to contain fission gas pressure and limit SiC fracture • PyC and SiC layers allow negligible transport of nearly all fission products

Mar 1, 2021 · TRISO fuels are structurally more resistant to neutron irradiation, corrosion, oxidation, and high temperatures (the factors that most impact fuel performance) than traditional reactor fuels," the agency said.

Aug 4, 2020 · Tristructural isotropic (TRISO) coated particle fuel is a ro- bust, microencapsulated fuel form developed originally for use in high-temperature gas-cooled reactors (HTGRs).
