description: This work is devoted to modeling the velocity and temperature fields in the SNF storage element in case of an out-of-design accident associated with sudden complete drainage of the SNF holding basin. Tasks that were solved during the research: 1. Development and debugging of a three-dimensional computational model in the ANSYS Fluent software package for studying the thermal state of one case with SNFA, taking into account heat exchange by convection inside the pencil case and the uneven distribution of residual SNF heat release in height. 2. Investigation of the stationary thermal state of SNFA in a dehydrated case for various values of residual SNF heat release and various boundary conditions. 3. Analysis of the results obtained and their comparison with data from works performed by other authors. In the work, a three-dimensional numerical model of a case from the BN-800 reactor was built in the ANSYS Fluent software package version 23.R2. Calculations of stationary temperature fields are performed by numerically solving conservation equations taking into account natural convection and thermal radiation for various values of residual SNF heat release. The conclusion is made about the influence of natural convection and radiant heat transfer on the thermal state of SNF.
