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 importance of handling the sizable mildly radioactive materials that fusion generates received more attention in recent years. Disposing such sizable radwaste in geologic repositories is not a viable option. We suggest changing what is now a costly waste disposal concern for fusion energy into a valued commodity through the further development of the recycling and clearance approaches. This paper reports the outcome of two recent activities that identified the challenges of handling the radioactive materials of ARIES-ACT-2 power plant along with the required design changes and R&D programs that make the recycling/clearance approach a reality, and the development of a new detritiation code that predicts the efficiency of tritium recovery from metallic materials – an essential process before recycling.
