Abstract:
1. A method for pretreating a fuel rod cladding tube for material tests, the method comprising: providing an aqueous electrolyte medium; providing an electrochemical three-electrode configuration having an iron-containing working electrode as one of said three electrodes; providing a fuel rod cladding tube; placing said fuel rod cladding tube in said medium; placing said three-electrode configuration having said iron-containing working electrode in the electrolyte medium; producing iron oxide particles in the electrolyte medium by anodic oxidation of the iron-containing working electrode; and at least partially coating the fuel rod cladding tube with an iron oxide layer by immersing the fuel rod cladding tube in the electrolyte medium containing the iron oxide particles said coating being free from anionic contaminations.
