| Abstract Scope |
Development of accident-tolerant claddings for the current reactor fleet focuses on surface coatings acting as corrosion and diffusion barriers to protect the tube. These coatings are only protective as long as they are adherent and continuous and must be hardy enough to accommodate large strains. With a variety of manufacturing techniques and processing parameters, it is difficult to predict which coating method yields ideal properties for insertion into a reactor. We propose a method for coating evaluation on tubes using a gaugeless ring pull test combined with digital image correlation. By relating visible coating failures with localized strain measurements, this technique provides a simple and quick method for assessment of coating adherence on cladding tubes and can enable screening for coating methods that yield undesirable mechanical properties. We demonstrate this technique on Cr-coated tubes of Zircaloy-4 manufactured via two different methods with a variety of processing parameters. |
