| Abstract Scope |
In response to the Fukushima accident in Japan in 2011, Westinghouse’s EnCore® accident tolerant fuel (ATF) program is developing and commercializing advanced fuel products with the main goals of improving safety and economic performance through more flexible operation and longer material use. The program includes a near-term ATF product which is comprised of chromium-coated zirconium-alloy fuel cladding and doped fuel pellets. Chromium coatings are applied via cold spray additive manufacturing technology and have been tested in the designed operating regimes in several nuclear power plants, providing real-world performance data on the coating. Post-irradiation examination (PIE) data and results from recent work on cold spray parameter optimization and coating performance testing will be presented and discussed. Results from hydrothermal corrosion testing performed at Westinghouse indicate coating quality has significant dependence on feedstock material. |
