Behavior of carbon 14 in used fuel claddings

Objectives :

Study of the 14C mobility in used fuel claddings (Zr and ZrO2).

Approach :

Density functional approach (DFT) is used to identify the possible interstitial sites and to calculate activation energies between them, to finally estimate the diffusivity properties of 14C in Zr and ZrO2 which are the main components of the fuel claddings.
