Overview

Commonwealth Fusion Systems (CFS) is collaborating with Massachusetts Institute of Technology’s Plasma Science and Fusion Center to build SPARC, a commercially relevant, net-energy device that will demonstrate that fusion can work as a power source for the first time in history. SPARC is on track for a 2025 completion, and will pave the way for carbon-free, safe, limitless, commercial power. Thornton Tomasetti is performing structural engineering, and mass concrete thermal modeling as a consultant to HDR and contractor support services for Bond, the General Contractor.

Highlights

  • As CFS prepares to scale quickly to bring fusion power to market, it is building a 47-acre campus with a 170,000-square-foot research facility.
  • The site also includes the company’s corporate offices and an advanced manufacturing facility.
  • SPARC is a compact, high-field tokamak built with high temperature superconducting (HTS) magnets.
  • SPARC is an important step to accelerate the development of commercial fusion energy.
