Objetivo
The impact of humic substances on the lengthen safety of nuclear waste disposal is quantified. Results are tailored for implementation in PA. Natural humic colloids have been shown to migrate like ideal tracers over long distances and time-spans. It has also been unarobiguously shown that there is a large potential impact by humic colloid mediated radionuclide migration. However, due to discrepancies between the behaviour of radionuclides from laboratory studies and natural chemical analogues, presently no final conclusion is possible on this issue.
This can only be resolved by development of adequate process understanding. The project takes a necessary broad approach, including development of model humic substances, generation of missing data and development of models and transport codes. The impact on PA is visualized by migration case studies. The long-term safety relevant actinide ions and iodine are studied.
