As part of the GDA process for the UK HPR1000 reactor technology, we have made available information on the reactor design as well as the technical documents that we submit to the UK regulators at each step of the process (see GDA process page for more information).
Step 4 commenced on 13 February 2020 and we have published the following draft documents:
- Pre‐Construction Safety Report (PCSR) V1
- Pre-Construction Environmental Report (PCER) V1
- Generic Security Report (GSR) V1
In addition, we published the following documents in January 2021:
- Pre-Construction Environmental Report (PCER) V1.1
- Pre-Construction Safety Report (PCSR) V1 Amendment Report
They can be accessed via the Step 4 page.
We invited the public to provide views or questions on the reactor design, safety and environmental aspects. All relevant comments we considered and responded to within 30 days. We will shared all comments received, along with our responses, with the regulators.
Please note that the GDA process does not cover the principles of nuclear policy or the siting of potential power stations.
The GDA is a continuous process and all comments received up until around four months before the end of the GDA were considered by General Nuclear System Limited and the regulators.
We have summarised some of the key themes we have received as part of the GDA comments process and the responses to these comments, which can be viewed on our Common Comment Themes page.
