Abstract
Super-homogenisation (SPH) factors were generated by a modified version of the code DYN3D for PWR fuel assemblies in hot-zero-power states defined in the OECD MOX/UO2 Benchmark. SPH factors averaged for each pin-material type and factors for each individual pin position were produced. The application of the SPH factors improves the accuracy of DYN3D calculations, especially for configurations with control rods inserted.
► We calculate super-homogenisation (SPH) factors for reactor core neutronics. ► SPH factors clearly improve accuracy for PWR states with control rods inserted. ► Pin-type-averaged cross sections and SPH factors are sufficient.
