Research project: Assessment of Sorbent Materials for the Remediation of Radionuclide Contaminated Groundwater

Currently Active: 
Yes

Decades of leaks have contaminated parts of the Separation Area at Sellafield with a mixture of anthropogenic radionuclides. The more mobile of these radionuclides (HTO, Sr and Tc) have polluted the groundwater aquifer under the site and are migrating towards the Irish Sea. In many non-nuclear sites in-situ sorbent materials in the form of permeable reactive barriers (PRBs) have been successfully used to treat polluted groundwater. PRBs provide an engineered zone that immobilises contaminants from groundwater flowing through it.

Project Aims

  • measure the sorption capacity and distribution coefficient (KD) of PRB materials taking into account relevant physicochemical characteristics (e.g. pH, Eh, complexants, colloids and competing ion effects)
  • determine the uptake kinetics and sorption mechanism of those materials
  • characterise physical and chemical changes that may affect their long term performance
  • investigate the impact of using simulant and site groundwaters on radionuclide uptake
