ABSTRACT
The renewed interest in ADSRs originates essentially in the proposals made by Bowman [2] and Rubbia [3]. The first advocated a molten salt thermalneutron subcritical reactor, while the second advocated a solid fuel, lead cooled fast-neutron subcritical reactor. Almost all more recent work on ADSRs elaborates on these two ‘primordial’ proposals. This is why we devote this chapter essentially to them.
