    Abstract

    In the framework of the McSAFE European Union project, Monte-Carlo-based multiphysics tools are being developed and optimized, with the objective of enabling the solution of full-core pin-by-pin depletion and transient problems in Light Water Reactors. In this context, an advanced and flexible Serpent2-SUBCHANFLOW coupling was developed for further use in pin-by-pin calculations. The implementation is based on an object-oriented methodology, in which each code is restructured as a solver class with a well-defined interface and the coupling is specified in a supervisor program. For verification purposes, problem 6 of CASL’s VERA benchmark, consisting of a single PWR fuel assembly at nominal operating conditions, was solved and the results were compared with published values.
