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.

Research and test reactors at national laboratories and universities are a cornerstone of nuclear engineering research and education since the first reactors were deployed at Oak Ridge and North Carolina State University. The population of university reactors grew to a high of almost 80 in 1970 but has dropped to 24 operating today. Only five remain at national laboratories. The US Department of Energy – Office of Nuclear Energy supports the remaining reactors through fuel and infrastructure funding. Beyond basic support, the fleet is innovating at existing reactors and proposing new designs, adding new capabilities for testing fuel, structural materials, and instrumentation and nuclear data.
