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 paper introduces a new implementation using virtual engineering approaches in support of the design and development of a compact pilot plant. Developing a compact pilot plant is a costly and high-risk approach. Risk and resource investments can be optimized by using commercially based virtual engineering, integrated simulation, and virtual prototyping environments in the design and development of a compact pilot plant. This paper identifies both the users of the virtual engineering environment as well as where in the system lifecycle it can be implemented. The environment will use and extend existing multiphysics models and simulation of products and characteristics through the development of system-level models and an investigation of virtual prototypes of component elements. The second level involves knowledge sharing across phases of the lifecycle of products, including all contributors and stakeholders in the virtual environment.
