Antares executes agreement with DOE to take reactor critical by July 2026

Sep 22, 2025

This week we executed our agreement with the U.S. Department of Energy (DOE) to take an advanced reactor critical on American soil by July 4, 2026.

This criticality test will validate our core physics and models, paving the way for our first power-producing reactor demonstration in 2027.

We are proud to partner with DOE to prove our hardware and advance U.S. nuclear development!
