Performance-assessment comparisons for a repository containing LWR spent fuel or partitioned/transmuted nuclear waste

This paper describes one component of the total-system performance assessment analyses being performed for a potential geologic repository containing partitioned and/or transmuted waste. An analysis of the releases of radionuclides at the earth`s surface due to human intrusion is presented here. The results are compared with other total-system performance assessments for the potential Yucca Mountain repository containing light-water-reactor spent fuel. Although most of the releases from a repository containing partitioned/transmuted waste are lower than those from a repository containing conventional spent fuel, the maximum releases are not significantly different.
