Rankings of Nuclide Importance in Spent Fuel for Shielding Applications

摘要

This paper describes the relative importances of various actinide, fissionproduct and light element isotopes with respect to storage and transportation shielding applications for spent fuel. Using simple computational models, the relative contributions of many isotopes can be individually analyzed and ranked. This ranking of importances is useful for both validation and understanding of the underlying importances of the many nuclides that can contribute to various waste handling issues such as dose rate analysis, criticality safety, decay, heat generation and residual activity levels.
