- INSWAREB proposes partnership with U.S. universities on irradiated construction materials
INSWAREB proposes a partnership with U.S. universities to research irradiated construction materials. The institute seeks access to Idaho National Laboratory’s test reactor to validate concrete made from fly ash and rice husk ash.
- Antares reaches reactor criticality under Trump pilot program, marking major nuclear milestone
Antares Nuclear's Mark-0 microreactor achieved criticality at Idaho National Laboratory under the U.S. Department of Energy's Reactor Pilot Program, established via President Trump's 2025 executive order. This marks the first advanced reactor to reach criticality under the program and the first privately developed non-light-water reactor in the U.S. in over four decades.
- Small modular nuclear reactor reaches criticality in first test
A small modular nuclear reactor developed by startup Antares reached criticality at the Idaho National Laboratory, marking the first new reactor design to achieve this milestone. The Trump Administration's executive order aimed to have three reactor designs reach criticality within a year, and Antares' design uses a TRISO fuel system with advanced safety features.
