First Assessment Carried Out on Four Designs Submitted for Nuclear Power Stations

Nuclear regulators, the Health and Safety Executive (HSE) and the Environment Agency (EA), today announced that the first step of 'Generic Design Assessment'(GDA) carried out on four designs submitted for new nuclear power stations had found no shortfalls at this stage - in terms of safety, security or the environment - that would prevent any of them from ultimately being constructed on licensed sites in the UK.

These findings are based on the claims made by the vendors for the designs, the basis of which will be assessed during the next steps of GDA.

The nuclear regulators have published a series of reports on their findings sfar, maintaining transparency and openness in the GDA process. The reports can be viewed at

GDA has been set up tensure that the safety, security and environmental aspects of new nuclear power stations are assessed early - at the design stage. The four designs subject tthe initial assessment were:

  • AECL’s ACR 1000;
  • EdF/Areva’s EPR;
  • General Electric-Hitachi’s ESBWR; and
  • Westinghouse’s AP1000.

Dr. Mike Weightman, Head of HSE’s Nuclear Directorate, and HM Chief Inspector of Nuclear Installations said, "Our job, through the Nuclear Installations Inspectorate and the Office for Civil Nuclear Security, is tprotect people and society from the hazards presented by the nuclear industry. As new nuclear power stations are being considered for the UK, it is vital for regulators tget involved with potential designs at the earliest stage - where regulatory assessments can have most influence - sthat we can ensure that the existing high standards of nuclear safety and security in the UK are being maintained and improved.

The GDA process has set out new standards in openness and transparency with the creation of a public involvement process whereby the public can view designs on the web and comment on them, and by our decision tpublish all our assessments reports on the web."

Joe McHugh, Head of Radioactive Substances Regulation at the Environment Agency said, "We demand that any new nuclear power stations meet high standards of safety, security and environment protection. As we begin the detailed assessment step of GDA, the reactor vendors and the regulators have much work tdbefore we will be able tdecide whether these designs can meet those high standards. We hope that the public will continue ttake the opportunity tcontribute tour assessments by providing their comments on the designs."

In the January 2008 Energy White Paper, the Government announced that if necessary it would run a prioritisation exercise tidentify, in conjunction with reactor designers and operators, which of the four designs subject tthe regulators' initial assessment are most likely tbe tbe progressed for licensing and construction.

Currently BERR are awaiting confirmation from all of the design companies that they wish tcontinue tthe next stage of GDA. If BERR ddecide that they need tundertake a prioritisation process, then at the end of that process the Secretary of State for BERR will make recommendations tHSE and the Environment Agency on the designs that should be given the highest priority for progressing through the next stage of the GDA process.

At the end of the GDA process - which is likely ttake around 3.5 years from start tfinish - the regulators will make statements setting out their conclusions about the acceptability of the designs.
