Underpinning the safety case for the use of colloidal silica based grout for waste containment

Project: ResearchEquipment Only

Description

X-ray Computed Tomography 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 based grouts for radioactive waste containment. We aim to use the element specific capabilities of synchrotron based X-ray CT at beamline I13-2 to investigate the effects of the grout injection on the geochemistry of Sr, Cs and U. We will also utilize the time resolved capabilities to determine the influence of complex solid matrices on the (injection) behaviour of the silica grouts.
