1285464 Reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 23 July 1970 [8 Aug 1969] 39924/69 Heading G6C A reactor core formed from an array of fuel members and with at least inner and outer core zones has the fuel members constituting the inner zone longer and more widely spaced than those constituting the outer zone, the fissile content of the fuel and the fuel member crosssection being constant across the whole core, whereby the variation of power output across the core is reduced. This core configuration enables a high mean coolant outlet temperature to be achieved without the need for coolant flow variation across the core. A specific example is described, applied to a fast breeder reactor cooled by liquid metal.
