The ISFSI for Susquehanna began accepting SNF for storage in 1998 pursuant to a general license. The ISFSI is located outside the plant’s security perimeter but within its own security fence approximately 490 feet west of the cooling towers. The ISFSI consist of three rows of storage modules: one consisting of 21 modules; a second consisting of 42 modules in a 2 by 21 array; and the third has 10 modules also in a 2 by 5 array. As of the December 2010, there were 3,783 SNF assemblies stored in 66 dry casks. The cask manufacturer is Transnuclear — the NUHOMS cask system. There are two different canister types in use: the older 52B canister type (27 casks containing 1,404 SNF assemblies), which is no longer being used; and the newer 61BT canister type (39 casks containing 2,379 SNF assemblies), which is the current canister being used. As of the end of 2010, there were 5,850 metric tons of SNF stored at the five nuclear power plant sites located in the State of Pennsylvania — Beaver Valley, Limerick, Peach Bottom, Susquehanna and Three Mile Island.
