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.

Five years have passed since the Broader Approach (BA) activities launched in 2007 under the framework of collaboration between Japan and EURATOM. In the International Fusion Materials Irradiation Facility (IFMIF) Engineering Validation and Engineering Design Activities (EVEDA) project, commissioning of the prototype lithium test loop was completed in March 2011, and a lithium flow of 25 mm thick at 15 m/s was obtained in July 2012. Components of the prototype accelerator are being fabricated. Injector will be delivered in Rokkasho in March 2013 followed by the validation test of the accelerator. In the International Fusion Energy Research Center (IFERC) project, five R&Ds mainly on DEMO blanket are being carried out at a newly constructed DEMO R&D facility. A high performance supercomputer with a LINPAC performance of 1.27 Pflops is now operational for the fusion simulation. In the Satellite Tokamak Program (STP) project, JT-60 torus disassembly is almost completed, and manufacture of tokamak components such as PF coils, vacuum vessel, cryostat are being fabricated on schedule. JT-60SA construction will start in Dec.2012. Present status and recent achievements of these BA activities are summarized.
