CGN and EDF, through their joint venture company General Nuclear System Limited, commenced the Generic Design Assessment (GDA) process for the UK HPR1000 in January 2017.
General Nuclear System Limited has been established to act on behalf of the three joint requesting parties (CGN, EDF and General Nuclear International) to implement the Generic Design Assessment of the UK HPR1000 reactor; more information on the each of these companies and the structure of General Nuclear System Limited can be found on the about us page. For practical purposes, General Nuclear System Limited is referred to as the ‘UK HPR1000 GDA Requesting Party’.
This website has been set up to publish information on the HPR1000 nuclear reactor design that is currently undergoing assessment by the UK nuclear regulators – the Office for Nuclear Regulation and the Environment Agency. You can find out more information about the process on our GDA process page.
On 13 February 2020, the regulators concluded that the information submitted by General Nuclear System Limited during Step 3 was sufficient to allow the start of Step 4.
As part of the GDA process we invited members of the public and interested parties to comment on the HPR1000 reactor design and the regulatory submissions that have made to the regulators. The comments process is now closed. A summary of some of the common comment themes we received and our responses can be found on our Common Comment Theme page.
As part of Step 4, the Environment Agency consulted on its preliminary conclusion. The consultation ran from 11 January 2021 to 4 April 2021. All consultation documents, assessment reports and the responses to the consultation are available on their website.
Within this site you will find information on the HPR1000 reactor technology, design, safety and environmental features. You can also access the range of technical documents that will be submitted to the regulators throughout the process in our document library.
