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.

Three recent experimental campaigns at Los Alamos National Laboratory have required unique application of traditional machining techniques to manufacture the components. For pRad experiments at Los Alamos Neutron Science Center (LANCE), unique planar targets with varying profiles required unique fixturing: a custom programming software to create concentric rings with a 2-deg taper that had five different sine waves machined across the face. Also, experiments using P8 modulated capsules for Asymmetric Burn Experiment (ABEX) experiments at Omega made use of a water-soluble ultraviolet-curable glue, which was used for holding and locating purposes during machining operations to produce an indicating datum, as well as a custom fixturing system, which allowed the ability to apply the impression gum from behind. Finally, for the milling of a 125-m-thick silica aerogel for dense-plasma equation-of-state experiments, we used an ultraprecision milling machine with a high-speed spindle and precise positional accuracy that permits micrometer depth of cuts at higher feed rates, which allowed for a reduction in machining time.
