Abstract/
Summary |
This paper deals with a structure and organization to handle nuclear reactor models and all the simulations. The phenomena involving in nuclear reactors are complex and often dependant to each other. However, the simulation of these phenomena requires a high precision in order to control the condition of irradiation. Frequently, physicists use different tools with several approximations at each interface. We propose a multi-physics data model describing geometries and materials, called Technological Entity data model. This approach permits a parametric description of a study, independent of the code used to perform the simulation. Technological Entity data model is able to delete, insert and deform only one part of the geometry. Since the model is a parametric one, different releases of the geometry can be stored. An application for an experimental device simulation in an experimental reactor demonstrates the feasibility of the proposed method. It consists in solving a time dependant neutronic/fuel behavior coupling problem on fuel rods. |
