A key component of a system that would deliver fusion energy in the U.S. has arrived at Commonwealth Fusion Systems’ (CFS) campus in Devens, Massachusetts. The company on October 28 said the first half of the vacuum vessel at the heart of SPARC, the group’s tokamak machine, is now on-site. The company on Tuesday said the “48-ton half-donut-shaped steel construction is instrumental to SPARC’s mission to demonstrate the core technology for our ARC fusion power plant,” adding, “We already have installed SPARC’s cryostat base in place, the foundation fusion machine called a tokamak, but the vacuum vessel gives a much better idea of SPARC’s final form and how it’ll carry us toward large-scale commercial fusion energy.” Brandon Sorbom, the company’s chief science officer and co-founder, said, “This is a really exciting time because we’re starting to really see the pieces come together for SPARC.” The company is now set to begin a new phase of SPARC assembly, as CFS crews working on the floor of Tokamak Hall are preparing the vacuum vessel for use by first adding diagnostic equipment, and then components made of heat-tolerant tungsten metal.
