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.

This paper reports the main results of the activation analysis of the ARIES-ACT1 power plant and its attractive environmental characteristics. The approach aims at examining several activation-related effects that influence the neutron-induced radioactivity, decay heat, waste classification, recyclability, and clearability of radioactive materials. Detailed studies are presented and provide information about the interdependence of material choices and activation response functions. It is also shown how the activation analysis can help address the inboard decay heat problem, one of the most important safety-related issues for tokamaks, and point the way to proper solutions through redefining the radial build to meet the design needs. Furthermore, the study suggests an integral management strategy to change what is now a costly waste disposal concern for fusion into a valued commodity via the further development of the recycling and clearance approaches.
