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.

This panel will provide an update on the status of the Versatile Test Reactor (VTR) project. The VTR is a sodium-cooled fast test reactor being developed with support from the DOE-NE and could become critical as early as 2026. It will provide accelerated irradiation testing capabilities to the entire advanced reactor community through allowing flexible testing under a multitude of environments. During this panel, multiple stakeholders will share their perspectives on the project, including views from the DOE, NRC, GEH, and national laboratories. This panel will also offer an opportunity for attendees to ask their questions.
