General description of the activity

SETRI group is involved in the development of scientific bases of waste management. Its studies are focused on the spent nuclear fuel behaviour under repository conditions as well as on the chemistry of actinides and fission products. Models are also being developed to predict radionuclide release proceeding from the interactions between spent fuel and groundwater.

The group also investigates reactive transport of pollutants in geological systems. Understanding the mineral-water interface is the main objective of these studies. Experimental techniques such as X-Ray Photoelectron Spectroscopy, X-Ray Absorption Spectroscopies (EXAFS, XANES), Scanning Electron Microscopy as well as powerful reactive transport models are used to characterize and understand the interactions between mineral surfaces and pollutants.

Another research line is the applications of nano- and meso-structured media in advanced water treatments and development of fundamental approaches to the theoretical and experimental studies of transfer phenomena in such media.
