We are currently assessing one new nuclear reactor design:
The EDF/AREVA's European Pressurised Reactor (EPR) design completed GDA in December 2012. We confirmed that EDF and AREVA's UK EPR reactor design is suitable for construction in the UK, granting design acceptance through formal documents called Design Acceptance Confirmation (DAC) and Statement of Design Acceptability (SoDA).
The Westinghouse AP1000 reactor design completed GDA in March 2017. We confirmed that Westinghouse's AP1000 reactor design is suitable for construction in the UK, granting design acceptance through formal documents, DAC and SoDA.
Hitachi-GE's UK Advanced Boiling Water Reactor (UK ABWR) was granted Design Acceptance Confirmation and a Statement of Design Acceptability in December 2017.
Nuclear new build is a policy matter for the Government, who will determine if any further reactor designs will be considered for construction in the UK, and prioritise those designs for assessment. A formal request for any further assessments will be submitted by Government to ONR and the Environment Agency.
