Paul Flynn – 2015 Parliamentary Question to the Department for Energy and Climate Change

The below Parliamentary question was asked by Paul Flynn on 2015-10-22.

To ask the Secretary of State for Energy and Climate Change, what proportion of the safety issues identified in the Generic Design Assessment for the European Pressurised Reactor that EDF Energy plans to build at Hinkley Point C have still not been resolved to the satisfaction of the Office for Nuclear Regulation.

Andrea Leadsom

The Office for Nuclear Regulation (ONR) has advised me that safety issues remaining at the end of Step 4 of Generic Design Assessment (GDA) of the European Pressurised Reactor were captured either as GDA Issues or Assessment Findings. GDA Issues are items that ONR requires to be addressed before a Design Acceptance Confirmation can be issued, successfully ending the GDA process, or before nuclear safety related construction can commence on site. All of the GDA Issues were addressed and closed by ONR in 2012. These Issues, the resolution plans to address them and information on their closure are published on ONR’s website:


Assessment findings are addressed throughout the post GDA phase through routine regulation under the nuclear site licence.
