BWX Tech. Wins $26M to Expand and Upgrade Triso Nuclear Fuel Manufacturing Line

Idaho National Laboratory has awarded the nuclear operations subsidiary of BWX Technologies a contract to expand and upgrade its Triso nuclear fuel manufacturing line.

The $26m contract will expand BWXT’s capacity for the manufacture of Triso fuel compacts and upgrade existing systems for delivering production-scale quantities of Triso fuel.

Triso refers to a specific design of uranium nuclear reactor fuel.

Triso is a shortened form of the term Tristructural-Isotropic.

Tristructural refers to the layers of coatings surrounding the uranium fuel, and isotropic to the coatings having uniform materials characteristics in all directions so that fission products are essentially retained.
