Multi-dimensional approaches for severe accident modelling of LWRs


Congress title :International Workshop on New Horizons in Nuclear Reactor Thermal Hydraulics 
Congress town :Mumbai
Congress date :07/01/2008

Summary

Severe accidents in PWRs are characterized by a continuously changing geometry of the core due to chemical reactions, melting and mechanical failure of the rods and other structures. These local variations of the porosity and other parameters lead to multi-dimensional flows and heat transfers. In this paper, a comprehensive set of multi-dimensional models describing heat transfers, thermal-hydraulics and melt relocation in a reactor vessel is presented. Those models are suitable for the core description during a severe accident transient. A series of applications at the reactor scale shows the benefits of using such model.
