Status and Prospects for Development of Groundwater Flow and Transport Modeling Techniques to Address the Long-Term Radiation Safety Issues

Abstract

The paper is focused on the problem of groundwater flow and transport modeling applied to safety assessment of nuclear facilities and development of relevant computational codes. The classification of typical tasks of the nuclear industry is provided, and specific features typical of different classes of simulated objects are analyzed, including their near and far fields. The most radioecologically relevant radionuclides are identified for each class. GeRa computational code is used as an example to analyze current trends of the development of hydrogeological modeling software.
