Connecticut Yankee Nuclear Power Plant

Connecticut Yankee Nuclear Power Plant (CY) was a nuclear power plant located in Haddam Neck, Connecticut. The power plant is on the Connecticut River near the East Haddam Swing Bridge. The plant was commissioned in 1968, ceased electricity production in 1996, and was decommissioned by 2004. The reason for the closure was because operation of the nuclear power station was no longer cost effective. The plant had a capacity of 582MW. Demolition of the containment dome was completed the week of July 17, 2006.

Kenneth Nichols, the deputy to Leslie Groves on the Manhattan Project, was a consultant for the Connecticut Yankee and Yankee Rowe nuclear power plants. He said that while the plants were considered "experimental" and were not expected to be competitive with coal and oil, they "became competitive because of inflation … and the large increase in price of coal and oil." The Connecticut Yankee plant was estimated to cost $100 million.

All original buildings were removed during decommissioning and the former plant site, according to federal and state environmental authorities, has been fully remediated and ready for any use including farming. Much of this work was completed by the Connecticut based Manafort Brothers Incorporated.

Due to the failure of the US Department of Energy to develop a national nuclear waste storage facility, all of the spent fuel used by the reactor remains at the site in an Independent Spent Fuel Storage Installation (ISFSI). There are a total of 43 dry storage casks, 40 of which contain spent nuclear fuel while the other 3 contain reactor components classified as high-level radioactive waste.
