About

Located in Haddam Neck, Connecticut, the Connecticut Yankee (CY) nuclear power plant began commercial operation in 1968 and produced more than 110 billion kilowatt-hours of electricity during its 28-year operating history.

In 1996, the CY Board of Directors voted to permanently close and decommission the power plant. After two years of planning and preparation, actual decommissioning began in 1998 and was completed in 2007.

Decommissioning reduces the amount of plant related radioactivity on the site, which allows the site to be released for future use. Decommissioning is a step-by-step, methodical deconstruction process that involves removing and disposing ofall radioactive materials to a licensed facility. These materials include piping, tanks, valves, pumps and components. Decommissioning also reduces radioactivity and hazardous materials that may remain in buildings and on the site after radioactive materials are removed. [1]
