# BWXT Supplies Antares TRISO Fuel

BWXT Advanced Fuels and Antares Nuclear have signed a multi-year agreement for BWXT to manufacture TRISO fuel for Antares reactors, beginning with an allocation of one metric ton of uranium. The agreement runs through the end of the decade, while later task orders will establish delivery volumes, schedules, and specifications. BWXT will use a production line also used for the federal Project Pele program; Antares’ electricity-producing Mark-1 reactor is planned for 2027. No government buyer, contract value, or solicitation number is disclosed.

- The agreement signals commercial demand for TRISO fuel and could support additional production if Antares expands reactor deployments.
- Contractors and suppliers serving advanced nuclear programs should account for the shared production line when assessing manufacturing capacity and delivery schedules.
- Because volumes and specifications will be set in later task orders, the initial agreement does not establish the full scale or timing of future fuel requirements.
