Abstract

The mechanisms of the basic release processes (diffusion, trapping, bubble formation, re-solution, grain boundary bubble formation and venting) of the fission rare gases Kr and Xe in nuclear reactor fuels are described. The fuels treated are oxides (UO(2), (U,Pu)O(2)) and advanced fuels (U,Pu)C and (U,Pu)N. The behaviour of other volatile fission products (Te, I, Rb, Cs) is also discussed, as well as effects of irradiation and burn-up of the fuel.
