Sizewell A is located near Leiston in Suffolk and is a twin reactor site. The site became fully operational in 1966, and shut down on 31 December 2006. Over 40 years of safe, compliant generation the site produced 110 TWh of electricity. The site has now completed defuelling with the final flask of spent fuel leaving site on Wednesday 6 August 2014.
Current phase: C&M Preparations
Key near term activities
The key activity for the site has been working steadily towards completion of defuelling which was achieved in 2015. The site is currently focusing on enabling demolition work in preparation for care and maintenance preparations.
It is also undertaking project works to enable its transition into decommissioning such as the electrical and control and instrumentation overlay projects. The site will also continue its ongoing efforts to ensure that systems and structures remain fit-for-purpose and use a process called “configuration control” to create opportunities for future deplanting and demolition work as resources and funding are available.
- The site completed defuelling well ahead of schedule and a month before the target date set by the Department of Energy and Climate Change.
- As a result, the site has safely and successfully removed over 99 per cent of of the radiological hazard.
