Joseph M. Farley Units 1 & 2 are located in Columbia, Alabama approximately 18 miles south of Dothan, Alabama. The Westinghouse PWRs are operated by Southern Nuclear Operating Co. and owned by Alabama Power Company, a wholly owned subsidiary of Southern Co. Unit 1 is licensed to operate until June 25, 2037, and its spent fuel pool can accommodate 1,358 assemblies. Unit 2 is licensed to operate until March 31, 2041 and its spent fuel pool can accommodate 1,386 assemblies. However, at all times each pool keeps a minimum of 287 assembly places unoccupied for new fuel and a full core offload capability.
The ISFSI at Farley began accepting SNF from Unit 1 in 2005 and from Unit 2 in 2010 pursuant to a general license. The ISFSI consists of three concrete storage pads each capable of holding 12 casks in a 2×6 array. As of the end of 2011, 480 assemblies were stored in 15 dry casks. The casks are manufactured by Holtec — the Hi-Storm cask system and the MPC-32 canister type. As of the end of 2010, 2,990 metric tons of SNF was stored at the two nuclear power plant sites located in the State of Alabama — Browns Ferry and Farley.
