Description
X-ray Absorption Spectroscopy beamtime awarded by Diamond Light Source (STFC) at equivalent funding value of £95,940.
Abstract of funded proposal:
In the proposed experiments we aim to develop the scientific case to underpin the use of novel colloidal silica grouts for radioactive waste containment. We aim to use the X-ray absorption spectroscopy (XAS) capabilities of the Core-XAS beamline (B18) to investigate the speciation of strontium and caesium (present in radwastes as radioactive fission products) adsorbed to solid matrices at legacy radioactive waste sites and, vitally, to determine the effects of colloidal silica grouts on the adsorption, geochemistry and speciation of Sr and Cs.
