Radioactive isotopes management in the reactive transport code HYTEC

Résumé

The use of isotopes has considerably improved our understanding of geology. Isotope analysis is traditionally used for rock dating and paleoclimatology, but it is also helping us to better understand elemental cycles, biogeochemical processes in different geological zones, the growth and stability of secondary minerals and the degradation of contaminants. In fact, advanced analytical methods have made it possible to highlight biogeochemical processes in which multiple reaction scenarios are possible. Introducing isotopes into reactive transport models is therefore of great importance in furthering our understanding of underground environments. While chemical isotope fractionation is already well taken into account in reactive transport solvers, the management of radioactive decay chains is generally not fully modeled in reactive transport problems. In this context, a new approach to radioactive decay chain management has been developed in the HYTEC reactive transport solver.
