Coupling between GeN-foam multi-physics solver and transuranus fuel performance code

This paper presents the GeN-transFoam solver, which is a coupled code between the GeN-Foam multi-physics solver developed at the Paul Scherrer Institute, and the fuel performance code TRANSURANUS developed at the Joint Research Center-Karlsruhe. It starts with a discussion on the possible coupling schemes between the two codes, which is followed by introducing the coupling scheme selected for the current version of the code. To demonstrate the improvements the TRANSURANUS models bring to the original multi-physics solver, a comparison study is conducted between the original GeN-Foam solver and the new GeN-transFoam solver
