Monte Carlo simulation of radionuclide transport through fractured media

Abstract: The presence of fractures within the host matrix may strongly affect the radionuclide mobility in the far-field of the current proposed solutions for underground radioactive waste repositories. In this paper a Monte Carlo simulation approach, based on analogies with neutron transport, has been developed for describing radionuclide transport in fractured media. The Monte Carlo approach here adopted is verified by means of comparison with analytic and numerical solutions for two different case studies. An application to a more complex and realistic case is also reported to show the potential of the proposed approach. [Copyright &y& Elsevier]
