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.

Manager, Radioisotope Power Systems Program
NASA Glenn Research Center
Mr. Carl E. Sandifer II currently serves as the Program Manager and Division Chief for the Radioisotope Power Systems Program at the NASA Glenn Research Center. In this role, he leads the development of power systems to enable NASA missions given a high priority by the scientific community to visit some of the harshest, darkest, and coldest locations in the solar system. Prior to this role, he served as the Deputy Chief of the Space Science Project Office at Glenn, and managed the science portfolio at the Center, which includes the development of new technologies, instruments, and systems to enable planetary science missions. Mr. Sandifer has a wealth of program and project management experience, along with a background in space mission design and systems analysis.
Carl graduated with a Bachelor of Science in Applied Mathematics degree from Bowling Green State University, studied Aerospace Engineering at Case Western Reserve University and earned his Master of Business Administration from Indiana Wesleyan University.
