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.

Hosted by the Manhattan National Historical Park team at Los Alamos National Laboratory (LANL), this tour will give you the opportunity to travel "behind the fence" on Laboratory property. You’ll visit Pajarito Laboratory, now called Technical Area 18, and discover everything from Los Alamos’ incredible prehistory to the beginning of the modern Laboratory – and, of course, the Manhattan Project. We’ll view the Pond Cabin, where Emilio Segrè’s Radioactivity Group made the pivotal discovery that the "Thin Man" plutonium bomb design would not work. You'll also see a battleship bunker used to protect equipment and staff during implosion design explosives testing and visit the site of Louis Slotin’s criticality accident.
