Abstract

The Superphénix SFR has been modelled using the new MERLIN flux solver module of the WIMS reactor physics code. The reactor was simulated for a range of calculation cases which investigated the neutronic effects of different temperatures and control rod insertions, for the purposes of validation against experimental data and verification against a Serpent benchmark. The WIMS results were found to be in good agreement with the experimental data and the Serpent results. Two different MERLIN models were constructed: a detailed hexagonal-Z geometry in 172 groups, and a hybrid method which used a simplified RZ model to condense the data used in the calculation into fewer groups before using the full hexagonal-Z geometry. This hybrid method was found to decrease the time taken for the calculations by a factor of five while retaining a good level of accuracy.
