4724f10301- effects of parameter variations on radionuclide transport aparat

The Federal Office for the Security of Nuclear Disposal in Germany from Europe region had released this tender for 4724f10301- effects of parameter variations on radionuclide transport aparat 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 the migration of radionuclides in host rocks requires the knowledge of numerous flow and transport-relevant parameters that characterize the host stone e g hydraulic permeability porosity molecular diffusiveness mechanical properties and last but not least a deep understanding of the phenomenological fluid 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 the long geological time scales several tau send up to 1 million years the control parameters e g thermal and mole-culture diffusiveness mechanical dispersiveness hydraulic permeability etc must take possible thermomechanical effects on the transport processes Particular attention must therefore be paid to the effects of parameter variations based on the above This FOV provides the input data and numerical workflows which can be used to validate the numerical codes developed by Base The research project is intended to enable the BASE as a regulatory authority not only to assess the scientific and technical results of the BGE mbH with regard to the criteria and requirements mentioned in the StandAG as well as the security examinations but also to assess the selected methodical approaches and their possible influence on the results achieved with tender notice no.
