摘要：
The article considers the 3D modeling of a gaseous medium mixing during a NPP severe accident using the STAR-CCM+ commercial code. The mathematical model of a passive hydrogen recombiner is described. The results of calculating a severe accident scenario and its comparison with the results obtained using the KUPOL-M code of lumped parameters are given. An analysis of possible hydrogen combustion and detonation is carried out.
