The approaches used in the EUCLID/V2 integrated code to calculate the core neutronics of a sodium-cooled fast reactor at the core destruction stage are described. Information is offered about the features of the operational algorithms of the SAFR severe accident module and the DN3D neutronics module. The ability of the integrated code to correctly calculate the processes involving core destruction is shown for an LOC accident.
