In the context of high-level nuclear waste repository safety calculations, the modeling of radionuclide migration is of first importance. Three dimensional radionuclide transport calculations in geological repository need to describe objects of the meter scale embedded in geologic layer formations of kilometer extension. A complete and refined spatial description would end up with at least mesh...

Carbon steel and compacted bentonite have been proposed as candidate materials for the overpack buffer, respectively, of multi-barrier system a geological high-level radioactive waste repository. corrosion may impair properties. The interactions products are analyzed with laboratory tests. Here coupled thermo-hydro-chemical-mechanical (THCM) models two types heating hydration tests performed on...

Geoaesthetics is the project of making aesthetic sense of nature through geological phenomena. The aesthetic appreciation of nature has recently become urgent because of the serious influence of the natural environment on human beings. The author’s geoaesthetical research is categorized into three problems: art in geology or geology in the arts as the close relationship between art and geology,...

Direct disposal of spent nuclear fuel in underground repositories stable geological formations is an alternative option for the reprocessing Japan. Upon breakdown barriers between waste storage containers and environment a deep repository, release radioactive nuclei from into will occur via groundwater. The be dependent on dissolution rate at fuel/groundwater interface. surface UO2 oxidized for...
