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.

Planar polymer targets are a fundamental component of high-energy-density (HED) laser experiments in which ion acceleration by high-intensity short-pulse lasers is being investigated. HED physics experimenters at Los Alamos National Laboratory (LANL) have pioneered the development of laser-driven proton, deuteron, and carbon ion acceleration; progressive experiments have required targets of controlled composition, thickness, and density. Here, we describe recent progress made in the production of ultrathin planar CH2 and CD2 targets of varying density for these experiments, fielded at LANL's Trident laser facility.
