Abstract

This paper summarises the general approach to the modelling of the corrosion of Zircaloy fuel cladding in PWRs. It discusses the problems arising from the present approach and presents evidence for why the current models break down. An alternative model based on recent experimental evidence on the mechanism of the irradiation and LiOH effects on Zircaloy corrosion is proposed, and it is shown that it can give oxidation curves of the observed form. Not all the evidence necessary for a complete description of this approach is yet available.
