The Westinghouse AP1000® pressurised water reactor is currently being assessed by the UK’s Nuclear Regulators (the Office for Nuclear Regulation and the Environment Agency) under their Generic Design Assessment (GDA) process.
In December 2011, Westinghouse received an Interim Design Acceptance Certificate and decided to pause the GDA process, pending the selection of the AP1000 plant technology for a project in the U.K. That selection occurred in 2014 when NuGeneration Limited (NuGen) announced plans to build three AP1000 units on the West Cumbrian coast.
In March 2015 Westinghouse announced that U.K. regulators and the company had begun the closeout phase of the GDA. In this next stage in the GDA process, Westinghouse will provide regulators with detailed technical information to address the remaining open issues in their assessment of the AP1000 plant design. Successful resolution of the open items will result in the granting of a Design Acceptance Confirmation (DAC) and Statement of Design Acceptability (SoDA). The target completion is March 2017.
