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.

With the goal of reducing the radiation damage and radioactive waste that will occur in a tokamak reactor using the deuterium-tritium cycle, this paper proposes a new magnetic scheme capable of confining hot and dense deuterium–helium3 plasmas. It consists of two 200-m-long cylindrical plasmas connected by semicircular sections to form a racetrack configuration. The reactor should be capable of producing from 7.8 to 13 GW of fusion power when operating at electron densities of 2 × 1020 m−3, temperature 40 keV, and density ratios of the two reactants from 1:2 to 2:1.
