Annular type metallic fuels have been proposed for ultra-high burn-up fast reactor applications. Traditional fission gas behaviors models rely on gas bubble swelling mechanisms which is sensitive to the hydrostatic stress induced by the early contact between the fuel and the cladding. It is perceived that such high sensitivity may not be suitable for the analysis of annular type metallic fuels. As a result, a mechanistic void swelling model has been applied to a fuel performance analysis of an annular metallic U-10Zr fuel. The characteristic performance calculation results are compared to experimental data from the AFC irradiation tests.
