Abstract
Abstract A fast breeder reactor consists of a core, an inner blanket consisting of a single ring of blanket elements surrounding the core, an outer blanket surrounding the inner blanket and a partition containing a moderating material and, preferably, a material which absorbs thermal neutrons separating the inner blanket from the outer blanket. Lithium can be used as both the moderating and absorbing material, tritium being formed therein as a useful byproduct.
