Аннотация

The approaches used in the SAFR/V1 module modeling the thermal destruction of fuel pins in fast reactors for calculating in integrated code EVKLID/V2 the melting of fuel pins and solidification of the formed melt are described. The enthalpy formulation of the heat-conduction equation is used. The numerical scheme used for the heat-conduction equation in performing the calculations is presented. The realized boundary conditions as well as a model of the gas gap in a fuel pin are described. The module’s capability of modeling heat propagation, including in the presence of a phase transition, is verified on the basis of analytical tests.
