Sizewell nuclear power stations, Nuclear power stations in Suffolk, England
Sizewell is a nuclear power station site on the Suffolk coast in England, where reactors sit on a flat strip of land between farmland and the North Sea. The complex includes a decommissioned Magnox reactor and an active pressurized water reactor, separated by fencing and security zones.
The first unit arose in the early 1960s as part of Britain's early nuclear programme and operated for over three decades. The second reactor followed in the mid-1990s with a different design based on American technology.
The station draws seawater from the North Sea to cool its reactors, a process visible through large pipe systems running toward the shore. Visitors often notice the distinctive white dome that has become part of the Suffolk landscape, visible from miles along the coastal paths.
The site sits beside the coastal road between Aldeburgh and Southwold, with beach parking available nearby. Walkers on the Suffolk Coast Path can view the buildings from a distance, but access to the grounds requires permission.
The older reactor used graphite as a moderator and was cooled with carbon dioxide, a method no longer employed in new plants. Its decommissioning takes many years as radioactive components must be carefully removed and packaged.
