The phenomena involved in the corrosion enhancement of Zr alloys under irradiation are analyzed. Among the basic mechanisms concerned, some are related to changes in microstructure of the alloy due to irradiation (precipitate evolution under irradiation and amorphous transformation), others to the transformation of the oxide layer (ZrO2) induced by neutron damage (irradiation-induced phase transformation of the zirconia). The effect of water chemistry and of the ionizing γ photons on the insulating zirconia will also be discussed. The original paper was published by ASTM International in STP 1423, Zirconium in the Nuclear Industry: Thirteenth International Symposium, 2002, pp. 20–29.
