In February 1970, the Brussels Study Group of the Gas Breeder Reactor Association was given the task of performing a design study of a helium-cooled breeder reactor of 1000MWe output. The fuel specification was to be based on mixed oxides of plutonium and uranium fabricated in the form of stainless steel clad fuel pins.
The dimensional and mechanical stability of these fuel pins depends on fuel and clad properties which may be affected by a helium-cooled fast reactor environment. In order to make a choice of materials and to set down their properties for design purposes, the following items have received consideration: fuel swelling, fuel melting, fission gas release, fuel and gap conductivity, clad resistance to deformation, ductility, irradiation-induced swelling of stainless steel, corrosion by helium or by fuel.
