FZR activities on in-vessel melt retention

Altstadt, E.; Willschütz, H.-G.

An overview of the modelling activities of FZR in the field of in-vessel corium melt retention (IVR) is given. The thermal and mechanical models and their application to various IVR scenarios are described. The thermo-chemical interaction between molten corium and reactor vessel steel is considered in the calculations.

Keywords: In-vessel melt retention; Finite element model; corrosion; VVER-1000; FOREVER experiments
