Abstract

Abstract: To improve the properties of homemade zircalloy clad tube and safety of reactor, the homemade Zirlo ally was impacted by water jet and investigated after high temperature and high pressure corrosion with dynamic water. The specimens were tested by SEM and AES to research the effect of the impact pressure of water jet on the oxide film. The results reveal that the water jet may cause good and harmful effect on corrosion of the zircalloy. The oxide film decreases by 4.3% when the impact pressure is up to 40 MPa, comparing with the specimen that is not impacted. However, the corrosion of specimens jetted with pressure of 10 and 20 MPa are worse than that of untreated specimens.

Key words: water jet, zircalloy clad tube, corrosion with dynamic water, oxide film
