Abstract: Commercial nuclear power plants in the U.S. are responsible for providing their own interim storage for excess spent fuel. A facility located onsite, acting as a buffer between in-pool storage and ultimate geologic disposal, is classified as an Independent Spent Fuel Storage Installation (ISFSI) and provides a viable alternative for supplementing in-pool storage capacity. The excess spent fuel is stored in NRC-approved dry-storage technologies (DSTs), which provide confinement against extreme environmental phenomena and sabotage. In conjunction with the DSTs, the ISFSI may vary from a sophisticated structure to a simple concrete slab on grade. It ensures that onsite and offsite exposures remain ALARA and has minimal impact on construction, plant operations, and future decommissioning costs.
