Abstract

This paper describes the most recent work in a programme of generic experimental and modelling sorption studies undertaken to increase confidence in the performance assessment for a potential high-level radioactive waste repository in Japan. The sorption of plutonium onto three rock samples was studied as a function of carbonate concentration under reducing conditions. Geochemical modelling was used to assist with experimental design and interpretation of results.
