Stainless steel was exposed to highly saline brines under anoxic and elevated temperature conditions. Samples were analyzed by various techniques in order to identify the nature of the secondary phases present in the corrosion layer forming at the steel–brine interface. Outcomes suggest that the corrosion layer has duplex structure, with an inner layer mostly of chromium (hydr)oxides and an outer layer made of iron- and nickel-based spinel compounds with admixed nickel (hydr)oxides.

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.

Short summary
The present contribution provides an overview on the collaborative project iCROSS and reports selected results. The impact of considering complex coupled processes in repository subsystems for the assessment of the integrity of a given (generic) repository arrangement will be discussed. The interdisciplinary team combines experimental work in the lab, in the underground rock laboratory and environmental simulations in order to achieve process understanding across variable scales.

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
Our contribution focuses on the release of fission gases during the dissolution process of two different types of spent nuclear fuel, i.e. UOX and (U, Pu)OX mixed-oxide fuels, in order to identify and quantify the role of fission gas release rates as an indicator of radionuclide source terms. Within our work, it is shown that, independent of the type of spent nuclear fuel, a comparable, fast initial release of fission gases is evident in all experiments.
