Graphite Machining for Mark-0 begins at Antares Prime

Jan 12, 2026

The Mark-0 build has officially begun. This graphite article will be a part of our bottom reflector. We’ve also now fabricated our vessel, and we began fabrication of our HALEU TRISO fuel back in October!

Look out for more updates to come on our fuel fabrication progress, our test facility, and our regulatory milestones.

We believe you must build a reactor to design a reactor - so that is exactly what we are doing.
