Sizewell A
Sizewell A Site is located on a 10 hectare site in Suffolk. The site generated 110 terawatt hours of electricity during its 40 years of operation and shut-down in 2006.
The site is in its decommissioning phase and the focus is now firmly on waste management and hazard reduction, with the cooling ponds the current priority.
Two major projects to accelerate demolition work have been completed, removing the cooling water crane and the two off-shore structures.
Building demolition continues with a number of facilities being dismantled and cleared, including the administration building, engineering building and C02 plant. The demolition of the National Grid sub-station is also planned.
