Abstract

Near-surface disposal facility is intended for the disposal of low-level nuclear wastes. The reliability analysis of this facility is carried out to estimate the efficiency of the system in containing the nuclear wastes. Subset simulation, an advanced simulation technique, is used for the reliability analysis of the system, and the bootstrap method of resampling is used to quantify uncertainties in sampling. Further, Sobol indices are used for sensitivity analysis. In the present analysis, radionuclide diffusion model is used assuming diffusion of radionuclides through the multibarrier system to reach the aquifer, and in the aquifer, the contaminant transport model is used for determining the radionuclide concentration at different distances from the source.
