Fusion
Published in William J. Nuttall, Nuclear Renaissance, 2022
Fission/fusion hybrid technology would also raise the possibility of benefit in the area of fission nuclear waste management. Such a technology has the potential for application in the transmutation of nuclear wastes and surplus radioactive materials (cf. Chapter 8). There would inevitably be elements of competition between the MCF community and those advocating accelerator-driven systems (ADS) for sub-critical fission power reactors if there were to be a major policy push towards partitioning and transmutation development. As things stand the Accelerator-Driven Subcritical Reactor (ADSR) community are further ahead, but the prospect of a fusion/fission hybrid for P&T remains a real possibility. Synergies between ADS physics and fusion engineering are further discussed in Section IV.9.10 in the context of materials irradiation tests to be undertaken by a separate facility in parallel with ongoing fusion research as part of an accelerated fast-track.

The accelerator-driven subcritical reactor (ADS) is one of the advanced reactor types with a high potential for the development of new-generation nuclear energy because of its good inherent safety, wide neutron spectrum, and high neutron balance.1,2 This system mainly aims to transmute long-lived radioactive waste, such as the minor actinides (MAs). The traditional ADS system3–5 consists of three main parts, namely, an accelerator for generating primary protons, a spallation target where the high energy of protons produces free neutrons in spallation reactions, and a subcritical core that is loaded with MAs or other nuclear fuel (Fig. 1).
