The Modelling of Migration of Radionuclides in Fractured Rock

Popis výsledku v původním jazyce

The weakest point in the nuclear energy production chain is a safe storage and remediation of burnt highly radioactive fuel. This contribution deals with a suggestion of mathematical model, which describes the percolation of groundwater in the fracturedsolid rock, the medium considered as feasible repository of dangerous nuclear waste. In general, there are three main possible approaches in modelling of fracture flow. When only a large-scale model is required and if there is no need to know flow details and transport behaviour in any site subarea, it is possible to use equivalent porous medium models. More complex than single continuum models are double porosity models. As a third and most accurate possibility, we can simulate the flow and transport in a statistically generated fracture network. Nowadays, due to their high computational requirements, it is possible to solve just local problems by using stochastic discrete fracture network models. For more complex description of th
