The main assumptions for modeling this group of events were highlighted. To take into account the peculiarities of modeling events with the spill of liquid radioactive media, a mathematical model is proposed, which allows to obtain a dynamic picture of the volumetric concentrations of the radionuclide in the air of the process room and the power release into the environment. The model has demonstrated an acceptable level of conservatism in its validation and verification at real events and is ready for implementation in research activities. Based on the analysis of the means of modeling the consequences of radiation accidents and incidents with the spill of liquid radioactive media, the necessary conditions for the integration of the developed mathematical model into the existing branch DSS are determined.
