Abstract
Since the 1980s, a number of DEMO reactors and fusion power reactors (FPRs) have been proposed by the international fusion community. Unlike fusion experimental reactors (such as ITER), DEMO reactors and FPRs will realize important functions such as the production and extraction of fusion energy as well as tritium self-sufficiency. These types of FPRs are usually characterized by high power, high neutron wall loads (NWLs), and complex structures and geometries, all of which pose great challenges in neutronics design. In this chapter, various concepts of DEMO reactors and FPRs are briefly introduced. Details of the objectives, methods, and principles of their neutronics designs are then discussed by taking FDS-II as an example.
