The machines being built, in order, and what each one proves.
1 MW liquid-fueled molten salt reactor on the Abilene Christian University campus. The NRC issued a construction permit in September 2024 and DOE approved the Nuclear Safety Design Agreement on 21 Jul 2026 under an Other Transaction Agreement, moving it into the pilot program. A university research and demonstration unit that produces no electricity, so commercial power conversion does not apply to this machine.
The 100 MWe commercial unit, targeted for Texas by 2029 and likely at Texas A&M RELLIS, with substantial design carryover from MSR-1. Because MSR-1 is a 1 MW campus research reactor that produces no electricity, MSR-100 is the first full-scale power-producing Natura machine - the full-scale demo and the product are the same article, as with Last Energy.
