The GRAAL2 glass alteration model: initial qualification on a simple chemical system

Abstract We present an upgraded version of the model GRAAL (Glass Reactivity with Allowance for the Alteration Layer model) to predict nuclear glass alteration. GRAAL2 accounts for the formation and diffusion properties of the gel which constitutes a passivating alteration layer at the interface bet...
