Abstract
The current version of the EVKLID/V2 code allows simulating the behavior of fast neutron reactors with liquid-metal coolants in steady state and transient operation modes, as well as in various design accidents, by carrying out associated neutron-physical, thermomechanical and thermal-hydraulic calculations. To calculate severe accidents in a fast reactor, the SAFR/V1 module has been developed. The module can work as a stand-alone module simulating the melting of a single fuel element and as a part of the EVKLID/V2 code, which allows calculating the destruction of the entire core, taking into account the melt ejection in the coolant, transferring the components of the broken fuel element to the upper mixing chamber, formation of blockages of the fuel bundle. Approaches used to calculate such processes are presented in this paper.
