Vacancy No. 15-2019/INE

PhD Position: Modelling of coupled reactive transport processes occurring at interfaces of geo-engineered barriers in the near-field of a generic nuclear waste repository

Job description

The Institute of Nuclear Waste Disposal - Karlsruhe Institute of Technology (INE-KIT) announces the opening of a PhD position in the field of modelling of coupled reactive transport processes occurring at interfaces of geo-engineered barriers in the near-field of a generic nuclear waste repository. The study is part of a research project of the Helmholtz Association of German Research Centres (HGF) and includes numerical simulations and data interpretation in a highly interdisciplinary team. The successful candidate has the opportunity to work closely with teams of scientists from various HGF research centres in order to significantly broaden her / his area of expertise.

The research of this PhD position deals with the application and the enhancements of coupled reactive transport modelling approaches for deep geological repositories of nuclear waste. The successful candidate will contribute to the development of a cross-scale numerical simulation concept, which covers various spatial scales, from the nanoscopic scale of chemical reactions of radionuclide species with minerals to modelling of the macroscopic radionuclide behaviour in the near-field and adjacent far-field. The specific task of this PhD position is to model coupled thermo-hydraulic-chemical processes at near-field interfaces such as the bentonite – concrete subsystem or the concrete - host rock subsystem, respectively. These numerical simulations will be based on a discretization of the studied sub-systems by means of Finite Element Methods (FEM) and modelling of the relevant chemical and transport processes, e.g. by using the “Retraso – Code Bright” programme package.

The candidate will be expected to communicate her or his research in the form of journal publications and presentation at scientific conferences and project workshops. 

Personal qualification

The ideal candidate should hold a graduate degree (M.Sc.) in a relevant field such as chemical engineering, chemistry, geochemistry, hydrogeology, mathematics or a related discipline. Experience and knowledge in numerical modelling based on Finite Element and Finite Difference Methods is required. Experience in programming or scripting languages (e.g. knowledge in Phyton) is advantageous. Candidates should have high motivation for creative research, the willingness to work in a team, and the ability for independent thinking and self-learning. Candidates are expected to be fluent in English language.
