Short summary
Decisions associated with radioactive waste management are made in the presence of irreducible and reducible uncertainties. Here, the identification of such uncertainties (namely numerical ones), their ranking according to relevance, their categorization, the elucidation of internal dependencies and cross-interactions is addressed. Suitable methodologies to analyse and illustrate complex uncertainty patterns are discussed.

Short summary
In the last few years, we have studied the immobilization of the long-lived fission product technetium-99 (99Tc) by various Fe(II) minerals. Those minerals enable the reduction of Tc(VII) to Tc(IV), which is crucial to decrease the migration of technetium in the environment. In the future, we want to analyze Tc immobilization strategies under more complex systems that could, in a more realistic way, improve environmental conditions.

The immobilization of trivalent actinides (Am, Cm) and their less toxic homologue (Eu) in feldspar, a very common mineral in our earth crust, was studied by sorption experiments and spectroscopic studies. The speciation was identified and used to gain thermodynamic parameters to develop a surface complexation model. To sum up, feldspar, a main component of crystalline rock, is suitable for retaining radionuclides in a deep radioactive waste repository.

Capturing the state of knowledge in radioactive waste management is a very important activity for supporting member states with the implementation of their national programmes towards the safe and effective management of waste. This requires the involvement of experts sharing their expertise and knowledge with the wider community. During the past 3 years, we have gained valuable insights into the procedures of involving experts and knowledge sharing, and the lessons learnt are shown here.

Short summary
The Repository Site Selection Act explicitly emphasises that targeting the disposal of high-level radioactive waste is a so-called learning process. We are of the opinion that the procedure and the available data should be combined with geoscientific knowledge to support the identification of siting regions. We propose this workshop and invite all experts who have dealt with the search for a repository site from a geoscientific perspective.

The talk presents highlights from the generic identification and evaluation of processes for co-disposal of high-level radioactive waste and low- and intermediate-level radioactive waste in clay rock, crystalline rock and salt rock in the context of the German site-selection process for a deep geological repository for high-level radioactive waste on behalf of the Federal Office for the Safety of Nuclear Waste Management (BASE).

Short summary
It has been recently recognized that the availability of liquid water may be a controlling factor for metal corrosion in a storage facility for radioactive waste. Since water is an educt for anaerobe corrosion, the reaction may be suspended or suppressed by the scarcity of water near the corroding surfaces. Gas pressure build-up through hydrogen generation may limit further water ingress. Our model focuses on the close coupling between gas generation through iron corrosion and water availability.

Short summary
An overview on the recent advances in the field of high temperature studies of radionuclides in aqueous solutions will be given. Besides summarizing information on key technical aspects relevant for high temperature studies, the effect of increased temperatures on the complexation of trivalent actinides with chloride will be discussed in more detail, to illustrate newly derived in-depth understanding of the impact of increased temperatures on the (geo)chemical behaviour of trivalent actinides.
Short summary
THEREDA represents a web-based system of programs enabling access to thermodynamic reference data for the needs of the final disposal of radioactive waste in Germany. It is the only polythermal database worldwide that covers the entire system of oceanic salts, including acids, bases and carbonates. THEREDA aims at calculation of solubilities in high-saline solutions and uses the Pitzer approach.
