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.

The realization of power from Magnetic Confinement Fusion is presently following a plan that will span several decades. The mainstream route is via ITER, combined with, or followed by, materials development on a Fusion Neutron Science Facility, then a DEMO reactor, which, as presently visualised, is considerably larger than ITER. We consider smaller-scale alternatives and developments which may make more rapid progress towards the much needed goal of economic, safe, clean fusion power, but still based on the tokamak.
