METHOD FOR THE PRE-TREATMENT OF A FUEL ROD CLADDING TUBE FOR MATERIAL TESTING

摘要

The method involves partially coating a fuel rod cladding tube (4) with a ferrous oxide layer (6) by a coating device (2) by immersing an aqueous electrolyte medium (8) containing ferrous oxide particles. The ferrous oxide particles are produced by anodic oxidation of a ferrous working electrode (10). The electrolyte medium is heated such that the electrolyte medium is provided in a region of subcritical boiling during deposition of the ferrous oxide particles on the fuel rod cladding tube in a boiling condition. The fuel rod cladding tube is heated by a heating device (34).
