Idaho National Laboratory is partnering with NVIDIA as part of the DOE-backed Genesis Mission to integrate AI and accelerated computing into reactor design, licensing, and operations, leveraging national supercomputing infrastructure to support digital twins, advanced simulation, and deployment acceleration...
Radiant has received DOE approval of its Preliminary Documented Safety Analysis for the Kaleidos reactor, marking the first full-power test approved under the DOE’s new authorization pathway and paving the way for final startup authorization at INL’s DOME facility...
During a visit to Idaho National Lab, Energy Secretary Chris Wright underscored the administration’s push for a nuclear “renaissance,” with Radiant’s microreactor slated for testing in the INL DOME ahead of a July 2026 milestone.
The U.S. Army is progressing with Project Janus to deploy a transportable microreactor by 2028, with Radiant already participating through the ANPI program; the effort supports defense energy needs while commercial use will still depend on NRC licensing...
Forbes spotlights Aalo Atomics, a Nucleation portfolio company, as part of a new wave of U.S. advanced-nuclear companies moving from concepts to manufacturing, with progress at its Austin factory, a 2026 criticality target at INL, and growing investor support.
Radiant has submitted its safety analysis to the Department of Energy, triggering a 45-day review that keeps the company on track to start up its first Kaleidos reactor at INL’s DOME facility next year...
The U.S. Army’s Janus Program will deploy nuclear microreactors by 2028, with Radiant’s Kaleidos design featured among the advanced systems supporting base energy resilience.
Radiant has selected Oak Ridge, Tennessee, for its first microreactor manufacturing facility after regulatory hurdles in Wyoming blocked plans for temporary fuel storage...
Growing Energy demand provided demand pull for both traditional and next-generation reactors throughout Q3 of 2025. Yet further boosting momentum was the announcement by the DOE that they had selected ten ventures for accelerated design review of a test unit. This has lit a fire under those and other ventures already making progress to try to get the DOE to allow them to build something by July 4, 2026.
DOE has named 10 advanced reactor teams—including Aalo and Radiant—for accelerated licensing reviews as part of a pilot program to get three test reactors running...
