Tesis doctoral de Qingchun Yang
This dissertation presents numerical models for in situ and lab diffusion experiments involved in the migration of radionuclides in the near and far fields of a deep geological repository for high level radioactive waste in clay. Numerical models have been performed for: 1) the design and interpretation of a long-term, natural-scale in situ diffusion (dr) experiment performed in a packed section into a borehole drilled vertically in the opalinus clay at mont terri in underground research laboratory in switzerland; 2) scoping calculations and interpretation of a mock-up lab experiment in bentonite-granite interface; 3) the interpretation of large-scale solid source diffusion experiments in callovo-oxfordian clay at bure site (france); and 4) the estimation of transport and retention parameters for dir (diffusion of inert and reactive tracers) in situ diffusion experiments performed on callovo-oxfordian clay at bure. A method to identify which parameters can be estimated and a method to study parameter identifiability of sorption and diffusion parameters are proposed.
