Neutronics Scoping Studies for Experimental Fusion Devices

A new Affordable Robust Compact (ARC) Fusion Reactor, which meets its goal in a cheaper, smaller but even more powerful, faster way to achieve Fusion Energy, with new high-field, high-temperature superconducting (HTS) magnets, has been designed in the US. SPARC will be the research tokamak aimed at the development of many ARC technologies. Ignitor is a proposed compact high-field tokamak that share with SPARC and ARC some design concepts, showing the convenience of this tokamak design development line. Neutronics and radiation damage scoping studies have been carried out for both designs. A general-purpose macroscopic model, set up by some of the authors in previous studies, has been used to estimate the radiation damage on selected machine components for the two cases. Solutions to solve the problem of radiation damage of the Toroidal and Poloidal Field Coils materials have been explored.
