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.

Some technological problems of radioactive fusion materials management are being addressed in the paper. These problems are being studied in the frame of the International Energy Agency (IEA) collaborative study on fusion radioactive waste. These studies address the management procedures for radioactive materials following the changeout of replaceable components and decommissioning of fusion facilities. Key issues include clearance levels, hands-on and remote recycling procedures, fusion permanent waste hazard assessment, and detritiation of activated materials.
