Background
Connecticut Yankee was a 560 MW pressurized water reactor on the shores of the Connecticut River. It began commercial operations in 1968 and ran for 28 years until 1996. The plant was permanently shut down in 1997 for economic reasons.
Decommissioning
Plant decommissioning commenced in 1998. In 2005, all spent fuel had been transferred to on-site dry storage. Plant decommissioning was completed in 2007. That year the federal license for the site was also reduced to the Stand-Alone Independent Spent Fuel Storage Installation (ISFSI) site. The NRC license will be terminated after the ISFSI is decommissioned. The plant owners have made no decisions regarding the disposition of the former plant site property and have established no timetable for making such a decision. Additional information may be found at the Connecticut Yankee website.
Socioeconomics
Connecticut Yankee is located in Middlesex County, Connecticut. As of 2016:
- Population: 160,000
- Per Capita Annual Income: $63,000
- Unemployment rate (not seasonally adjusted): 1%
Prior to ceasing operations in 1996, Connecticut Yankee accounted for 60 percent of the tax base for the Town of Haddam, paying $5M of the town’s $10.5M budget in 1991. With the assessed property valued at $43M (2015$) the plant is the largest property tax payer to Haddam’s tax base. Today, in steady state ISFSI operations, the property taxes are approximately $1.4M annually.
