NEUP CINR-21-23989: New advances in engineered backfill materials: phosphates as a potentially important add-on to the existing bentonite concept.

This project will assess contamination risk, when waters accidentally breach through EBS and interact with SNF heated by radioactive decay. Experiments on growth of phosphate minerals will be conducted at controlled redox conditions at 25-300 degrees C. We will quantify iodide, iodate, U(IV), and U(VI) uptake by phosphates. Quantitative understanding of nuclides entrapment mechanisms will permit to optimize the composition of a new backfill mixture of improved efficiency.
