| Abstract Scope |
Accident Tolerant Fuels (ATFs) have the potential to enhance the safety of nuclear power plants by offering better performance during normal operation, transient conditions, and accident scenarios. The development of ATF such as Cr-coated Zircalloy relies on the implementation and success of advanced coating technologies. This work investigates the surface characteristics of ATF cladding tubes of Chromium coated Zircaloy-4 manufactured using different coating techniques, Physical Vapor Deposition and Cold Spray. A comparison of their surface characteristics with current fuel cladding Zircaloy will be presented. After Cr-coating, the contact angle decreased, changing the surface wetting characteristics of the bare substrate. Various roughness parameters and chromium thicknesses have been assessed by advanced materials examination techniques such as Profilometry, AFM, SEM, and FIB. Besides, the hardness and adhesion of the coatings have been measured using micro-indentation and adhesion pull-off testing, respectively. |
