[en] A simple model is presented which allows the easy computation of ΔGO2 and ΔHO2, at any temperature and oxygen and plutonium content for UPuOsub(2+-x). Some implications on the nature of the defects are drawn, values for their energy of formation are given and their concentrations may be computed. (Auth.)

[en] Performance assessment is faced to a number of uncertainties inducing discrepancies in modelling results. Sedimentary rocks and fractured media have to be considered separately. As uncertainties lowers the confidence level, regulators demand the waste management organizations to provide proof of their ability to deal with the dispersion of the parameters. Several techniques have been developed using geo-statistics, fractals, stochastic direct or indirect modelling, and applied both to sedimentary and fractured media. (R.P.)
