- Antares Nuclear's Mark-0 advanced reactor completed a zero-power fueled criticality demonstration at Idaho National Laboratory.
- This test confirms the reactor's safe operation and paves the way for electricity production by 2027.
- The Mark-0 is the first of multiple advanced reactors to meet President Trump's July 4, 2026 deadline.
- It marks the first privately developed non-light-water reactor to reach criticality in the U.S. in over 40 years.
- The demonstration validates safety and performance, informing future commercial reactor designs and licensing.
- Microreactors like the Mark-0 are anticipated for terrestrial, space, and military applications.
- The Reactor Pilot Program accelerated development, leading to the establishment of the Nuclear Energy Launch Pad.
