These web pages are joint regulator pages for both the Office for Nuclear Regulation (ONR) and Environment Agency. The regulators are working together to ensure that any new nuclear power stations built in the UK meet high standards of safety, security, environmental protection and waste management, through a process called Generic Design Assessment (GDA).
Before a new nuclear power station can be built and operated in the UK, in addition to the reactor design going through the GDA process, the proposed operator must obtain permission from regulators and Government in the form of:
BEIS has today published its GDA Entry Guidance and opened the Generic Design Assessment to Advanced Nuclear Technologies.
The new Entry Guidance reflects that the work the nuclear regulators have completed to modernise GDA.
We updated our joint GDA guidance in preparation for this last year, and wait to be invited by government to start regulatory activity.
This report provides details of learning to come out of the Sciencewise supported project.
You can make a comment about a design via the reactor designer’s website. The reactor designer will respond to the comments and issues raised.
