- 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.
- A safer nuclear fuel is gaining steam — but cost remains a hurdle
The U.S. is seeking to revive its nuclear industry by advancing TRISO fuel, a safer and more stable alternative to traditional fuel rods. However, the technology faces challenges due to high costs.
