Welcome To The UK New Nuclear Site

The Westinghouse AP1000® pressurized water reactor has successfully completed review by regulators in the United Kingdom, who concluded their Generic Design Assessment (GDA) by issuing Design Acceptance Confirmation (DAC) and Statement of Design Acceptability ( SoDA) for the Westinghouse technology. The DAC and SoDA were issued on the 31st March 2017 by the Office for Nuclear Regulation (ONR) and the Environment Agency (EA), respectively.

Westinghouse initiated the GDA process, which applies to England and Wales, in 2007. After receiving Interim Design Acceptance Confirmation (iDAC) and Interim Statement of Design Acceptability (iSoDA) in December 2011, the company paused the review process pending selection of the AP1000 plant technology for a project in the U.K. The GDA resumed in 2014 after NuGen announced plans to build three AP1000 units at the Moorside site, and was completed in 2017.
