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 NRC regulates 31 research and test reactors (RTRs), many of which are located on college or university campuses. Because of the COVID-19 Public Health Emergency, many campuses temporarily closed, also placing the reactor in a secure shutdown mode, some for extended periods of time. However, select facilities continued to operate throughout the pandemic to meet “Critical Infrastructure” needs, as identified by the U.S. Department of Homeland Security. At the start of the pandemic, the Test, Research and Training Reactor (TRTR) organization along with NEI has been hosting routine calls with stakeholders for industry benchmarking, sharing of best practices, and to discuss generic areas where regulatory relief would be needed across the fleet. This panel will discuss the operational and regulatory response from the RTR fleet, as well as the unique transition towards opening campuses for the Fall 2020 semester.
