Work Package 1

Aim To define the processes which control transport of key radioactive contaminants in natural and engineered environments.

Objectives

To define the chemical speciation of critical radionuclides, a key control on behaviour, defining oxidation states and complex form in the solution and solid states and at interfaces;
To develop a quantitative, mechanistic understanding of radionuclide retardation both theoretically and experimentally.
To explore the role of biological processes in radionuclide mobility and the potential for in situ remediation.
To define key processes in generic waste repository which dictate a source term for radionuclide release into the far-field.
To develop and apply environmental transport models for radionuclides over a range of spatial scales from nanometers to tens of meters, including integration and up scaling of models.
