✦ Synopsis

The surface structure of UO 2 at different cross-section average burn-ups was studied with fractal analysis methods. Micrographs of the surface, subjected to both ''as-polished'' and ''as-etched'' treatments, with a magnification of 1250β€’ have been used to this end. It was shown that the fractal properties of the surface strongly depend on the radiation damage of the material. Some evidences for existence of self-organization processes in UO 2 at high average burn-ups were obtained.

We propose a new approach, based on the cellular automata, for processing and modeling the structure dynamics of UO 2 at different cross-section averaged burn-ups. Micrographs of the material surface, subjected to both ''as-polished'' and ''as-etched'' treatments, with a magnification of 1250Γ‚ have

High burn-up nuclear fuel elements have been intensively studied for prolonged lifetime of existing reactors and for next-generation advanced reactors. This paper presents an improved lumped-differential formulation for one-dimensional transient heat conduction in a heat generating cylinder with tem
