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.

A new approach for simulation of the interaction of space and lunar dust with the surface of spacecrafts has been proposed. The approach is based on creating a dusty plasma cloud when the substance imitating the space or lunar dust is treated with high-power pulsed microwave radiation in the developed experimental facility. The facility consists of a high-power gyrotron (75 GHz, 0.8 MW); a plasma-chemical reactor; and a diagnostic complex, which includes optical emission spectrometers and a high-speed camera. The approach has been tested using the substance of the Tsarev meteorite, which represents a typical substance of meteorites. It was found that the substance mainly keeps the phase composition; however, the particles change their morphology due to rapid heating and melting.
