Abstract

This paper presents the latest results from a programme of generic sorption studies undertaken to increase confidence in data underpinning the performance assessment for a potential high-level radioactive waste repository in Japan. The sorption of plutonium onto basalt and sandstone was studied as a function of redox conditions that ranged from strongly reducing to oxidising. Geochemical modelling was used to aid experimental design and the interpretation of results.
