The article describes the technology of creating three-dimensional fuel rod geometric models (fuel elements) of WWER-type power reactors for performing finite element calculations (physical and strain-stress computation) using software MSC.MARC and ABAQUS. For three-dimensional modeling the container type fuel rods used in these reactors represent a complex structure; that is why it is difficult to create models. The offered approach uses special programs in the PYTHON language, and for the user the modeling work is reduced to specifying the geometric parameters of the fuel rod structure. At the final stage, the component fragment assembling is made. It is possible to take into account in modeling the defects arising in fuel rods during their manufacture and operation (chips and cracks in tablets, misalignment of the tablets, ellipticity of the fuel cladding, etc.).
