Abstract

The general objective of Task 2 in work package “Assessment of Chemical Evolution of ILW and HLW Disposal Cells”, short ACED, is to provide geochemical and coupled reactive transport models for assessing the geochemical evolution at steel/clay material and steel/cement material interfaces in terms of corrosion rates, geochemical alterations and physical alterations. Task 2.1 focusses on the steel-clay interface and follows a combined modeling-experimental approach in order to increased confidence and decreased uncertainty of model simulations. Existing experiments to be modelled include the long-term in-situ experiments FEBEX and MaCoTe as well as new lab experiments performed at ÚJV and the Fe/Bentonite interface cells experiments (FBexperiments) run by CIEMAT. New laboratory experiments are looking at the effect of Fe(II) on smectite of Uni Bern and on steel interaction with claystone of MTA. The deliverable is summing the activities performed in the first period of the project.
