Antares achieves zero-power criticality at INL
Leveraging more than $140 million in private capital fundraising, over 322,000 square feet of operational manufacturing space, and multifaceted partnerships with the Departments of Energy and Defense, reactor start-up Antares has become the first company involved in the Reactor Pilot Program to achieve zero-power fueled criticality—a full month ahead of the July 4 deadline set by President Trump’s Executive Order 14301.
This milestone, announced yesterday, was achieved with the company’s Mark-0: a sodium heat-pipe-cooled, TRISO-fueled microreactor. The Mark-0 is a forerunner to the company’s flagship design, which it calls the R1. For Antares, this development represents a key validation of its reactor physics, control systems, and supply chain.

Space Nuclear Power and Propulsion is beneficial because of the efficient energy that can be produced from small amounts of fuel. Both the National Aeronautics and Space Administration (NASA) and the Defense Advanced Research Projects Agency (DARPA) are planning exciting new missions that will be discussed on the opening day of the Nuclear and Emerging Technologies for Space conference. Join us to the learn the latest news and future plans for these missions.
