Monte Carlo simulation of radionuclide migration in fractured rock for the performance assessment of radioactive waste repositories
Abstract
The estimation of radionuclide migration within a fractured medium is a fundamental task in any performance assessment aimed at verifying the protection offered by radioactive waste repositories. In this paper, we present a novel application of a dual-permeability, Monte Carlo simulation approach based on Kolmogorov-Dmitriev (KD) theory of branching stochastic processes. The Monte Carlo simulation scheme allows to easily handle the high degree of complexity of the problem, accounting for non-homogeneities both in space and time. Particular attention is devoted here to the inclusion of time-dependencies. An illustration is given with reference to a realistic case study of 239Pu migration.
