Introduction to the session reactor models

In this series of slides it is shown how the reactor model is a key issue for fuel cycle simulation. The purpose of a reactor model is to predict first, the fuel quantity needed for the loading of this type or reactors and secondly, the spent fuel composition. It may be difficult to anticipate isotopic compositions in case of multi-recycling. Another issue is that reliable reactor models are also indispensable for studying reactor synergies when the deployment or the renewal of a fleet of reactors is considered.
