Connecticut Yankee Atomic Power Company

Connecticut Yankee Atomic Power Company, Connecticut’s first nuclear power plant, began commercial operation, in Haddam Neck, on January 1, 1968. High operational costs led to its closing in 1996. In 2004, the plant was decommissioned, a process that included dismantling the plant and constructing a facility for the long-term storage of spent nuclear fuel and high-level radioactive waste. This project was completed in 2007.
