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 prediction of electromagnetic loads on blanket module 1 of the ITER device during a plasma disruption event is considered. This analysis is performed for a number of design variations (of the blanket module) and different disruption events.The key features of the analysis procedure will be presented including the geometric description of the blanket module composed of a first wall, shield block, and vacuum vessel. The modeling of the plasma current will also be described.The electromagnetic analyses are performed using the Opera-3d software. The transient eddy currents are first calculated, from which the electromagnetic loads are determined. Once these loads have been calculated they can also be exported for additional post-processing to assess the mechanical loading effects.
