Four US companies have achieved a significant milestone by reaching criticality in their prototype nuclear reactors, meeting a goal set by the Trump administration. This technical achievement, demonstrating a sustained nuclear chain reaction, was met by Antares Nuclear, Valar Atomics, Deployable Energy, and Aalo Atomics. While this marks progress for emerging nuclear technologies aimed at increasing emissions-free electricity supply, these reactors are still in the zero-power phase and must overcome substantial engineering challenges, such as adding cooling systems, to eventually produce electricity for the grid. The companies project aggressive timelines for commercial deployment, but regulatory hurdles with the Nuclear Regulatory Commission could impact their progress. AI
