AbstractAbstract
[en] The purpose of modeling of corrosion products mass transfer in circuits of LMFBR with sodium and lead coolant is to evaluate the conditions for effective performance of coolant and structural materials, including the permissible levels of coolant temperature increase and concentration of impurities in coolant as well as to obtain quantitative data on output and accumulation of solid-phase impurities in the elements of hydraulic path of LMFBR circuits. There were developed two types of models for the evaluation of corrosion products mass transfer in sodium-cooled circuits in one-dimensional approximation. The first model takes into account the dissolution and crystallization of impurities being transferred in sodium. The second model takes into account also chemical interaction of impurities in sodium. In both models the elements of the hydraulic part are simulated by round channels. The Lagrange system of coordinates is used in the mathematical description of processes in channels
