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.

Electron cyclotron heating (ECH) power modulation experiments in the GAMMA 10 tandem mirror have been started in order to generate and control the high heat flux and to make the ELM (edge localized mode) like intermittent heat load pattern for divertor simulation studies. ECH for potential formation at the plug region (P-ECH) produces the electron flow with high energy along the magnetic filed line. The peak heat-flux of more than 10 MW/m2 was obtained during the ECH injection within the available power of ECH. It is found that arbitrary intermittent heat flux is possible by modulating the ECH power. 0.05 MJ/m2 heat pulse has been obtained with 380 kW 5ms ECH pulse, which indicates possibility of 0.5 MJ/m2 level with multi-MW ECH power.
