Abstract [en]

The first part of this paper reviews the different temporal coupling methodologies that are currentlyemployed for the transient simulation of LWR cores. The second part shows preliminary resultsfrom the implementation of some suggested coupling improvements, including high-ordercorrections to the exchanged coupling fields and a dynamic time step control technique, for thesimulation of an exemplary reactivity insertion transient analysed using the European NURESIMLWR simulation platform.
