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 International Energy Agency (IEA) has been promoting the IEA Environment, Safety and Economic Aspects of Fusion Power program for many years. Among the tasks of this program, one task in particular deals with radioactive waste management in order to analyze the issue of the final destination of fusion activated and tritiated materials after their use in a fusion power reactor. A collaborative study on these aspects has been carried out in recent years. An optimized waste management strategy is proposed, with the goals of avoiding underground disposal as much as possible, maximizing recycling of activated materials within the nuclear industry, and/or clearance and release to commercial markets if materials contain only slight traces of radioactivity. Some technological problems and recent research advances in this field are summarized.
