High level radioactive waste (HLW) requires a great level of isolation from environment to assure long term storage. Isolation of the HLW in deep geological repositories (DGR), through a multi-barrier concept, is currently the most accepted approach adopted by Governments to ensure long-term safety.
We have developed a new optical sensor based on the incorporation of Eu3+ in a high charge clay for tracking the long-term physical-chemical behavior of high-level radioactive waste (HLW) contaminants in DRG under mild hydrothermal conditions.
The aim of this project is the synthesis of a new family of 2D-engineered nanoclays (ENCs) with novel electrostatic layer features for improving their dual functionality, as optical sensor and as engineered barrier in DGR.
