2026-10-29 (~8:17 AM ET, WNN — world-nuclear-news.org/articles): the Antares–BWXT agreement now carries named fuel specifics — an initial tonne of TRISO fuel for Antares's microreactors, with volumes that could increase as deployment requirements evolve to support the advanced reactor program. Development: fleshes out the Oct 27 multi-year BWXT fabrication arrangement (POWER) with the fuel type and first checkable quantity; still procurement-grade — no deliveries dated, no deployments or offtake named. Watch: delivery schedules, the remaining DOE safety-review stages for the Mark-1, named deployment partners.
2026-10-27 (~10:29 AM ET, POWER Magazine — powermag.com): Antares announced on Oct 27 a multi-year agreement with BWX Technologies for advanced nuclear fuel fabrication, plus initial DOE safety approval for its Mark-1 microreactor — both framed as key requirements for the planned transition from reactor testing to electricity production and military deployments. Development: the fuel-supply layer (Centrus prepaid HALEU contract, Sep 2026) gains a fabrication anchor at BWXT; the DOE step is an initial safety approval, not a licence or full authorization. Watch: remaining DOE review stages, delivery schedules, named deployment partners.
2026-09-18→21 Centrus signed multi-year prepaid HALEU contract with
Antares (deliveries by end of decade — ledgered) and pitched
"unobligated uranium" to microreactor developers. Framatome signed the
first higher-enriched-fuel reload contract. Red Book: resources OK.
