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 ITER actively cooled tokamak is the next-generation fusion device that will allow study of the burning plasma over hundreds of seconds. ITER plasma-facing component (PFC) real-time protection will be mandatory to minimize operational risks as water leaks and critical heat flux lead to degradation of PFCs. The protection systems routinely used on Tore Supra (TS) or JET are based on infrared (IR) imaging systems controlling and monitoring the power load on the PFCs through surface temperature measurements. Thanks to TS expertise in actively cooled tokamak and long-pulse operation, three urgent research and development domains are discussed in this paper addressing the feasibility and the performance of the PFC protection function for the new and harsh environment of ITER: (a) the understanding of IR signals in a reflective environment using a physics-based light model simulation; (b) a PFC protection data processing architecture for event detection and identification; and (c) the feasibility, performance, and prototyping of the first optical component of the imaging systems - actively cooled, facing the plasma - which will impact the image quality and therefore PFC protection performance.
