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.

Theoretical analysis and interpretation of experimental measurements indicate the need to extend the fluid theory used in the tokamak plasma edge to include ion orbit loss of thermalized ions and to retain (mainly) electromagnetic pinch forces in the momentum balance in order to derive transport equations which conserve particles, energy, and momentum. The features of such an extended steady-state fluid theory have been derived from first principles in several papers and are summarized herein.
