- Description :
- According to the law on the search and selection of a location for a repository for highly radioactive waste (location selection law-standing), a location is to be determined that offers the best possible security for the construction of a depth bearing for highly radioactive waste for 1 million years.It is required to concentrate the radioactive waste to be stored in a depth warehouse in such a way that at least for this period, the radionuclides (marginal) contained therein can reach the biosphere in only very small quantities. The simulation of migration of radionuclidesIn host rocks, the knowledge of numerous flow and transport-relevant parameters that characterize the host rock (e.g. hydraulic permeability, porosity, molecular diffusiveness, mechanical properties) and last but not least a deep understanding of the phenomenologicalFluid transport processes. In this FOV, the bidders will develop numerical models to examine the groundwater flow and the radionuclide transport in the three potential host stones in the worst case of a radionuclide release from the repository (worst-case scenario). Due to theLong geological time scales (several tau transmitters up to 1 million years) must take into account the control parameters (e.g. thermal and mole-culture diffusiveness, mechanical dispersiveness, hydraulic permeability, etc.) Possible thermomechanical effects on the transport processes. SpecialAttention must therefore be paid to the effects of parameter variations due to the above mentioned the ultimate goal to evaluate the effects of parameter variations (uncertainties) on the migration of RN about geological time and room scales and to what extent indicators as they are currentlyare defined in the EndlsianFV (2020), for which worst-case scenario can be used.
This FOV provides the input data and numerical workflows that are validated by Baseentw ... - Documents :
