First reactor in Trump pilot program hits milestone to ramp up nuclear nationwide
The first small modular nuclear reactor in the Trump administration’s pilot program to develop advanced nuclear energy has hit a crucial milestone toward deploying more nuclear power across the country.

TL;DR
- The Antares Nuclear Mark-0 reactor achieved criticality, a crucial milestone for advanced nuclear energy development in the U.S.
- This zero-power fueled demonstration confirmed the reactor's safety and self-sustaining chain reaction capabilities.
- The achievement is part of the Trump administration's initiative to boost nuclear energy deployment and could lead to commercial generation by 2027.
- Small modular reactors (SMRs) offer a smaller footprint and faster deployment compared to traditional nuclear facilities.
- While criticality doesn't mean immediate electricity production, it validates the technology for future licensing and deployment, including at military installations.
