The significant fuel damaging event and subsequent station damage at the Fukushima Daiichi nuclear power plant in 2011 highlighted the need for Light Water Reactor (LWR) fuels with enhanced tolerance to severe accidents. A worldwide initiative is underway to develop and implement the needed Accident Tolerant Fuel (ATF) concepts. The US Department of Energy has mandated that meltdown-resistant, accident tolerant nuclear fuels that would enhance the safety of present and future generations of LWRs must be demonstrated as soon as possible in commercial US LWRs by the domestic fuel vendors. This seminar will discuss the current status of worldwide ATF research and development, and the plans to meet the ultimate goal for the deployment of accident tolerant fuels and associated technologies in US reactors.


Bill Gassmann is a graduate of Penn State with a BS in Nuclear Engineering and of Georgia Tech with an MS in Nuclear Engineering and is a licensed Professional Engineer in Nuclear Engineering in the state of Pennsylvania. He is currently the lead engineer for implementation of the Light Water Reactor Accident Tolerant Fuel (ATF) program at Exelon Nuclear and is the chairman of several industry ATF committees. Previously at Exelon Nuclear, Bill has managed the fleet Nuclear Fuel Reliability and fleet Reactor Engineering Oversight groups and additionally has been a Reactor Core Design Engineer and a member of the site Reactor Engineering staff at the Limerick Generating Station.
