Abstract

Fuel assembly arrangement for use in a nuclear reactor core, characterized in that it comprises a plurality of spaced fuel elements containing a first nuclear fuel, a member in said fuel assembly containing burnable toxicant, and a second nuclear fuel in per at least the portions of said fuel elements within a neutron diffusion length of said burnable toxicant, said second nuclear fuel having a greater fission cross-section than said first nuclear fuel.
