Antares Nuclear's Mark-0 reactor has successfully completed its zero-power fueled criticality demonstration at the Idaho National Laboratory, marking the first private non-light-water reactor to achieve this milestone in over 40 years. This achievement supports the DOE's Reactor Pilot Program aimed at advancing nuclear technology.
- 01The Mark-0 reactor reached criticality on Thursday, a significant milestone for private nuclear development in the U.S.
- 02This achievement is part of the DOE's Reactor Pilot Program, initiated in 2025, to fast-track next-generation nuclear technologies.
- 03The reactor's success validates the government's streamlined regulatory process for nuclear projects.
- 04Data from this test will inform the design of future commercial reactors expected to produce electricity by 2027.
- 05The Mark-0 project aims to support various applications, including military energy resilience and space exploration.

Antares Nuclear's Mark-0 advanced reactor has achieved a significant milestone by completing its zero-power fueled criticality demonstration at the Idaho National Laboratory, marking the first time in over four decades that a privately developed, non-light-water reactor has reached criticality in the United States. This achievement, part of the Department of Energy's (DOE) Reactor Pilot Program launched in 2025, underscores the potential of innovative nuclear technologies. US Energy Secretary Chris Wright hailed the event as a historic moment for American nuclear energy, emphasizing the importance of the Mark-0's design for future commercial deployments. The data gathered will guide the design and licensing of subsequent reactors, expected to begin electricity production in 2027. The Mark-0 is anticipated to play a crucial role in diverse applications, including military energy resilience and future space missions, thus catalyzing a transformative shift in the national energy landscape.
