This paper evaluates the thermohydraulic aspects of modeling multi-purpose container (MPC-31) with VVER-1000 spent nuclear fuel (SNF) during its long-term storage in HI-STORM container (designed by Holtec International). The paper describes the main approaches and assumptions applied for the development of correspondent ANSYS CFX model, as well as provides the main calculation results for one of the cases of MPC-31 loading with SNF. The results of calculations were used in the regulatory review
