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.

Production of high plasmas in anchor-cell is necessary for MHD stabilization on the tandem mirror GAMMA10. Plasma heating in anchor-cell has been carried out by ICRF system (RF1) with both east and west Type-III antennas installed in the central-cell. By using an additional ICRF system (RF3) with a bar-type antenna installed in the east anchor-cell, more effective anchor heating has been confirmed. East Type-III and the bar-type antennas are driven with the same frequency and phase difference between two antennas can be controlled in the experiment. Plasma parameters depend on the phase difference between both antennas. Increase of the line density and the soft X-ray signal are observed in the opposite phase. Stable plasma production with only east RF1 and east RF3 are also confirmed.
