1/5 TRISO particles
TRISO particle fuel is structurally more resistant to neutron irradiation, corrosion, oxidation and high temperatures than traditional reactor fuels.

2/5 TRISO particles
TRISO particles have a fuel kernel made up of a mixture of uranium and oxygen or uranium oxycarbide that is then coated with three layers: (1) an inside layer of high-strength pyrolytic carbon, (2) silicon carbide, and (3) an outer layer of pyrolytic carbon.

Each particle acts as its own containment system thanks to its triple-coated layers. This allows them to retain fission products under all reactor conditions.

TRISO particles can be fabricated into cylindrical pellets for use in either high-temperature gas or molten salt-cooled reactors.

TRISO particles can also be fabricated into billiard ball-sized spheres called “pebbles” for use in either high-temperature gas or molten salt-cooled reactors.
