OECD/NEA Benchmark for Neutronic Analysis of Sodium-cooled Fast Reactor Cores with Various Fuel Types and Core Sizes

    OECD/NEA released a set of benchmarks for sodium-cooled fast reactor cores in 2016. A set of four numerical benchmark cases was initially developed with different core sizes and fuel types in order to perform neutronic characterization, evaluation of the feedback coefficients and transient calculations. Two “large” SFR core designs were proposed by CEA: those generate 3600 MWth and employ oxide and carbide fuel technologies. Two “medium” SFR core designs proposed by ANL complete the set. These medium SFR cores generate 1000 MWth and employ oxide and metallic fuel technologies.

    For a reasonable comparison, select the results from benchmark report these used the same evaluation database as SARAX.
