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.

Anthropogenic CO2 is a major cause of climate change, according to scientific consensus. Energy derived from fossil fuels is one of the main sources of atmospheric CO2. This session will address means for reducing energy-related CO2 emissions with emphasis on economic aspects. This panel session will feature the following speakers: 1) Keynote speech by William Magwood, Director General of OECD’s Nuclear Energy Agency : Costs of Decarbonization -- The Role of Nuclear Energy in the Energy Transition ; 2) Luc van den Durpel, President of Nuclear 21 : Energizing Sustainability -- Nuclear’s Unique Contribution; 3) Bill Sacks, co-author with Gregory Meyerson of forthcoming book entitled “Dyseconomies of Scale: Capitalism, the Green New Deal, and Nuclear Power” : Wind and Solar Energy Cannot Scale: The Importance of EROI ; 4) Yoon Chang, Argonne Distinguished Fellow, Argonne National Laboratory : Improving Fuel Recycling Economics to Enable Large-Scale Nuclear Power Deployment
