What happened
On day two of NECX 2026, Aalo Atomics, Antares Nuclear, and Deployable Energy discussed efforts to reach criticality by Executive Order 14301's 4 July target. The conference record also says officials from Kentucky, New York, and Utah outlined plans to expand nuclear activity in their states.
The discussion sits alongside a related narrative of early-stage reactor validation. That record notes Westinghouse's eVinci completed zero-power criticality testing, while the three companies above reported criticality progress around the same target.
Why it matters
Taken together, the conference claims point to a cluster of criticality-related milestones and state-level expansion planning. For observers of advanced and microreactor programmes, the combination is relevant because it joins technical progress claims with policy and deployment intentions.
However, the available record does not establish how far any individual programme has advanced beyond the reported milestone discussions, nor does it provide detailed state plans. The conference opened on 26 August, according to the supplied record.
What to watch
The next useful receipt would be programme-specific evidence of criticality results from Aalo Atomics, Antares Nuclear, and Deployable Energy, along with more detailed public plans from Kentucky, New York, and Utah. Such material would help distinguish conference statements from independently documented progress.
Watch for programme-specific criticality evidence and detailed public nuclear-expansion plans from the three states.
