C CT YANKEE NUCLEAR POWER PLANT
DECOMMISSIONING & DEMOLITION
The Connecticut Yankee Nuclear Power Plant in Haddam Neck,
Connecticut, was among the first Nuclear Power Generating
Facilities in the United States to undergo decommissioning
and demolition. The facility, a 619 MW Pressurized Water
Reactor (PWR), was commissioned in 1968 and operated until
1996, when it was shut down for economic reasons. Manafort
was contracted by the Connecticut Yankee Atomic Power
Company to handle the decommissioning, which was completed
successfully in 2007. The project involved extensive work,
including commodity removal, contaminated groundwater
management, and the removal and packaging of approximately
30,000 CY of contaminated soil.
Manafort's scope of work also included the decontamination and demolition of various structures to achieve License Termination. These structures ranged from the Diesel Generator Building and the Administration Building to the Reactor Containment Building and the Spent Fuel Building. The project also encompassed the removal of power and telephone duct banks, chemical storage facilities, and various other operational and support buildings associated with the plant's function. Each phase of the project required careful planning and execution to ensure compliance with safety and environmental regulations.
As one of the first decommissionings of its kind, the project presented unique challenges. Manafort was tasked with developing innovative and safe methodologies for decontaminating and demolishing the facility's structures. The company leveraged its extensive demolition and construction experience, alongside a team of industry experts, to complete the project within the three-year schedule and budget. Close coordination with the Connecticut Yankee Atomic Power Company was crucial in achieving a successful and safe project outcome.
