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.

The National Ignition Facility (NIF) is a high-energy-density-physics, experimental user facility that focuses up to 1.8 MJ of UV light in 192 laser beams onto a mm-sized target at the center of a target chamber. This paper describes how we conduct experimental shots on the NIF. We review processes and tools used to facilitate experiment planning and operations. Safety and radiological aspects of NIF’s operations are discussed. We also describe efforts to continuously improve operational efficiency and further increase shot rate.
