Abstract Scope |
Accident-tolerant fuel (ATF) cladding materials are designed to improve nuclear reactor safety by serving as a potential alternative to zirconium alloy cladding. One approach to improving the corrosion resistance of Zircaloy-4 cladding involves the application of a chromium (Cr) coating, which acts as a protective layer. Cr-coated Zircaloy-4 prepared by two different coating deposition methods, cold spray and physical vapor deposition, have been investigated under simulated incident scenario conditions. The samples were heated to three target temperatures (up to ~1200°C) using induction heating which allows for high heating rates. After a set time, the samples were quenched with water. Experiments were conducted in both dry air and steam environments. By examining the surface characteristics and microstructure of the Cr-coated Zircaloy-4 under these conditions, this research aims to improve understanding of the practicality of using Cr-coated Zircaloy-4 as an ATF cladding material and compare the performance of the two manufacturing methods. |
