Abstract
In this paper, previously implemented steady state coupling of Monte Carlo code Serpent, subchannel code SUBCHANLOW and fuel behaviour solver SuperFINIX is extended for transient simulations. The coupling is done within VTT’s reactor analysis framework Kraken using the multi-physics driver Cerberus. Differences between steady state and transient simulations in the coupling of thermal-hydraulics and fuel behaviour solutions are highlighted and the additional implementation required for the transient simulations is described. As an initial test case for the coupling, a control rod ejection accident in a single depleted fuel assembly is modelled. Finally, future work related to improving the capability of the code system to model coupled transients is briefly discussed.
