Since 2015, the U.S. nuclear industry has been rapidly developing nuclear fuel technology to improve the safety and flexibility of the nuclear fleet. In only four years, three nuclear units have installed ten different fuel technologies for testing including coated claddings, ferritic steel cladding, chrome-doped uranium dioxide pellets, and uranium silicide pellets. Efforts are now underway to utilize the improvements of these technologies to extend the burnup limits and increase the five weight-percent enrichment limit. This can allow plants to lower fuel costs or extend fuel cycle length from 18 to 24 months. This presentation will look at the technologies being developed and how the industry intends to move forward with the implementation of these new fuels and the benefits they provide.


John B. Williams is the Nuclear Fuel and Analysis Director for Southern Nuclear Operating Company. In this role, he is responsible for nuclear fuel, safety analysis, and risk-informed engineering for the Southern Nuclear fleet of generating plants. John has more than 20 years of experience in nuclear fuel, specifically reactor core design and licensing, dry storage of spent nuclear fuel, nuclear fuel procurement, and reactor engineering. He joined Southern Nuclear as an engineer at the Southern Nuclear Corporate Headquarters in 2005. Prior to joining Southern Nuclear, he was a nuclear engineer for the Tennessee Valley Authority. John serves on the Department of Energy Industry Advisory Board for the Advanced Fuels Campaign and is the Utility Lead for the Nuclear Energy Institute ATF Working Group Safety Benefits Task Force. John is a graduate of the Nuclear Engineering program at Georgia Institute of Technology. He lives in Birmingham, AL with his wife, Carol.
