Development and verification of a multigroup SP3 method for reactor calculations
Beckert, C.; Grundmann, U.;
A nodal approach for the multigroup SP3 equations was developed and integrated in the DYN3D code. The method is verified by pinwise multigroup calculations for a steady state of the OECD/NEA and U.S. NRC PWR MOX/UO2 Core Transient Benchmark. The results of different approaches including diffusion theory are compared with the reference transport solutions of the code DeCART. Different approaches of the diffusion coefficient used in the SP3 equations are investigated. The SP3 results obtained with the transport cross section of multigroup diffusion theory show a good agreement with the DeCART transport solutions.
