Heat Transfer Modeling and Computational Experiment for Uranium Dioxide Fuel Fragment Surrounded by Concrete
Authors: , ,
Abstract: The problem is of interest for nuclear power safety and some other fields. Non-stationary twodimensional boundary task for non-linear heat flow process in cylindrical rod of dioxide uranium surrounded by cylindrical concrete layer is considered with account of the real physical properties of materials depending on temperature, as well as accounting an internal heat generation of radioactive material. The mathematical model of a heat transfer process is realized as computer program for the FLEX PDE platform. Based on the model the computational experiments have been performed and their analysis was made. The results obtained maybe useful by performing the nuclear safety analysis, as well as by model calculations in constructing the passive protection systems against severe accidents at the nuclear power plants.
