    "abstract": "This paper deals with the comparison between thermal and Fission Enhanced\nDiffusion (FED) of uranium into zirconia, representative of the inner face of\ncladding tubes. The experiments under irradiation are performed at the Institut\nLaue Langevin (ILL) in Grenoble using the Lohengrin spectrometer. A thin\n$^{235}UO\\_2$ layer in direct contact with an oxidized zirconium foil is\nirradiated in the ILL high flux reactor. The fission product flux is about\n10$^{11}$ ions cm$^{-2}$ s$^{-1}$ and the target temperature is measured by an\nIR pyrometer. A model is proposed to deduce an apparent uranium diffusion\ncoefficient in zirconia from the energy distribution broadening of two selected\nfission products. It is found to be equal to 10$^{-15}$ cm$^2$ s$^{-1}$ at\n480$\\circ$C and compared to uranium thermal diffusion data in ZrO$\\_2$ in the\nsame pressure and temperature conditions. The FED results are analysed in\ncomparison with literature data.",
