Project Details


Beamtime at the core EXAFS beamline (B18) at Diamond Light Source, funded through Diamond Light Source.

Abstract of research proposal:
This proposal is the fifth beam time application that is crucial to delivering the experimental programme of the NERC Biogeochemical Gradients and Radionuclide Transport (BIGRAD) consortium (award number NE/H007768/1; BIGRAD focuses on radionuclide, rock, mineral, and microbiological reactions in a representative Chemically Disturbed Zone (CDZ) surrounding a Geological Disposal Facility (GDF) for radioactive wastes. Building on our previous work, this AP-14 beamtime application will be critical to permit XAS analysis on our final work on uranium (U) and technetium (Tc) fate in: (i) model iron oxide and carbonate mineral phases; (ii) biogeochemical cycling systems; and (iii) aged mineral incorporation systems that are critical to understanding the evolution of the CDZ and its impact on radionuclide mobility.
