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 U.S. Department of Energy – Nuclear Energy supports student research through direct support of research and development (R&D) programs across the United States as part of the Nuclear Energy University Program (NEUP). Additionally, the Integrated University Program (IUP) works concurrently to attract qualified nuclear science and engineering students (NS&E) to nuclear energy professions by providing undergraduate-level scholarships and graduate-level fellowships. The scholarships and fellowships are focused on two-, four-year, and graduate programs in science and engineering disciplines related to nuclear energy such as nuclear engineering, mechanical engineering, electrical engineering, chemistry, health physics, nuclear materials science, radiochemistry, applied nuclear physics, nuclear policy, radiation protection technology, nuclear power technology, nuclear maintenance technology, and nuclear engineering technology. The papers in this session are outcomes made possible by this support.
