1 PublicationSuper-homogenisation factors in pinwise calculations by the reactor dynamics code DYN3D
Grundmann, U.; Mittag, S.
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.
Keywords: LWR; reactor core model; multigroup; simplified P3 approximation (SP3); pinwise; super-homogenisation (SPH)
