EPRI is leading a demonstration project that will instrument a dry cask system to collect data on the behavior of high burnup used fuel during loading and storage. With no clear path for ultimate disposition, spent fuel will continue to be stored in dry storage for an extended period. To better understand the long-term storage and transportation behavior of high burnup used fuel (＞45 GWd/MTU), EPRI is conducting a full-scale demonstration of an instrumented storage cask loaded with high burnup fuel. Nuclear plants have been shifting from lower burnup to higher burnup fuels in recent years, and continued research is needed to better understand the impacts, if any, of storage, transportation and used fuel management on high burnup fuels.
