Specification and characterization of dense fuels for liquid metal cooled fast breeder reactors

Abstract The specifications of a given nuclear fuel depend on the general requirements of the fuel cycle and especially on the pin design and the reactor operation conditions. For the dense LMFBR fuels these requirements have changed several times in the course of the development of the LMFBRs since 1950. By following the course of this development it is shown how one arrived at the fuel specifications and pin design which are in agreement with the current fuel cycle requirements.
