Development of Cr Cold-Spray Coated Fuel Cladding with Enhanced Accident Tolerance

Original language description

Accident Tolerant Fuels (ATF) are currently of high interest to researchers in the nuclear industry as well as in governmental and international organizations. One widely studied ATF concept is multi-layer cladding (also known as coated cladding). This concept is based on a traditional Zr-based alloy (Zircaloy-4, M5, E110, ZIRLO etc.) serving as a substrate. Different protective materials are applied to the substrate surface by various techniques, thus enhancing the accident tolerance of the fuel. This study focuses on the results of testing of Zircaloy-4 coated with pure chromium metal using the cold spray technique. In comparison with other deposition methods, e.g. PVD, laser coating or CVD, the cold spray technique is more cost efficient due to lower energy consumption and high deposition rates, making it more suitable for industry-scale production. The Cr-coated samples were tested at different conditions (500°C steam, 1200°C steam, PWR pressurization test), pre-characterized and post-characterized by various techniques such as SEM, EDX or nanoindentation; results are discussed. Results of the steady-state fuel performance simulations using the Bison code predicted the concept’s feasibility. It is concluded that cold-spray Cr-coating has high potential benefits but requires further optimization and out-of-pile and in-pile testing.
