Spent fuel pools (SFP) are storage pools (or "ponds" in the United Kingdom) for spent fuel from nuclear reactors. They are typically 40 or more feet (12 m) deep, with the bottom 14 feet (4.3 m) equipped with storage racks designed to hold fuel assemblies removed from reactors. A reactor's local pool is specially designed for the reactor in which the fuel was used and is situated at the react… Webreactors). Nearly all the SNF is stored at four locations: the Hanford Site in Washington State, the Idaho National Laboratory (INL) in Idaho, the Savanah River Site (SRS) in South Carolina, and the Fort St. Vrain Independent Spent Fuel Storage Installation (ISFSI) in Colorado (see the Board’s 3fact sheet on DOE-Managed Spent Nuclear Fuel). photographer jack shear
