Uncertainty analysis for performance assessments of radioactive waste disposal systems

The prediction of the long-term performance of radioactive waste disposal systems may be improved by using uncertainty analysis techniques. Such analysises provide both quantitative and qualitative information on predictions made using computer models, thereby indicating the level of confidence in the results. These proceedings present the findings of a workshop organized by the NEA and US Department of Energy to develop a better understanding of the available methods for carrying out uncertainty analysises and to formulate general recommendations on their use, based on experience to date
