description: By ANSYS Fluent software package version 19.R3, a numerical model was built and a study was made of the temperature state of the spent nuclear fuel (SNF) of the BN-800 reactor under conditions of an out of project accident caused by instant complete drying of spent fuel pools. Stationary temperature field calculations in the spent fuel pool (SP) compartment were performed by numerically solving the conservation equations taking into account natural turbulent convection and thermal radiation for various values of SNF residual heat release. Two scenarios of the accident were considered: with forced and natural ventilation of the spent fuel compartment, i.e. in conditions of complete power loss of SP. For all considered cases of out of project accident stationary temperature fields in the compartment of SP, cask for SFAs and single SFA were obtained. For each set of considered initial data, it was concluded if the specified maximum allowable temperature of fuel claddings of 800 C was reached or not reached. Recommendations for some proper ways of cooling SFAs under accident conditions are given.
