Abstract
n the paper, the specification of a new neutronics benchmark for a large Sodium cooled Fast Reactor
(SFR) core and results of modelling by different participants are presented. The neutronics benchmark describes
the core of the French sodium cooled reactor Superphénix at its startup configuration, which in particular was
used for experimental measurement of reactivity characteristics. The benchmark consists of the detailed
heterogeneous core specification for neutronic analysis and results of the reference solution. Different core
geometries and thermal conditions from cold “as fabricated” up to full power were considered. The reference
Monte Carlo solution of Serpent 2 includes data on multiplication factor, power distribution, axial and radial
reaction rates distribution, reactivity coefficients and safety characteristics, control rods worth, kinetic data.
The results of modelling with seven other solutions using deterministic and Monte Carlo methods are also
presented and compared to the reference solution. The comparisons results demonstrate appropriate
agreement of evaluated characteristics. The neutronics results will be used in the second phase of the
benchmark for evaluation of transient behaviour of the core.
