Horizon Nuclear Power today welcomed the announcement that the UK ABWR has been approved for use in the UK, paving the way for the technology to be built at Horizon’s planned developments on the Isle of Anglesey and in Oldbury-on-Severn.

These projects will create tens of thousands of jobs and ultimately provide more than 5.4GW of clean, secure and affordable electricity, enough to power some 10 million homes.

Approval marks the conclusion of the Generic Design Assessment (GDA), a rigorous technology assessment by the UK regulators. This milestone has been achieved on time, thanks to the proven quality of the ABWR and the close collaboration of the Hitachi-GE, Horizon and GE-Hitachi team

This is another achievement for the ABWR (Advanced Boiling Water Reactor), four of which have been successfully built and operated – to time and budget – and the design has now achieved approvals under four different regulatory regimes worldwide.

Duncan Hawthorne, Horizon CEO, said:

“This is a huge milestone for Horizon and a major leap forward for us in bringing much-needed new nuclear power to the UK. Nuclear can deliver high volumes of stable low carbon energy, which makes it a vital part of the country’s electricity mix and once up and running, both Wylfa Newydd and our Oldbury site will supply clean, reliable power to the UK for decades to come.

“It’s testament to the strength of the combined team, and the proven nature of the technology, that the GDA process has been completed and delivered on time.”

Tadashi Kume, President & Representative Director of Hitachi-GE, said:

“Meeting the famously high standards of the UK regulators  and completing GDA within our five year target further demonstrates the strength of this project, and capability of the team delivering it. GDA is a thorough and rigorous assessment, and receiving approval on schedule is a credit to the outstanding design of the UK ABWR.

“Since 2012, we have been the subject of extensive assessment and scrutiny by the regulators. Throughout this process, their expertise and professionalism has been second to none. We now look forward to supporting Horizon’s ramp-up of site-specific licensing for Wylfa Newydd.”

The GDA approval of the UK ABWR comes on top of steady progress being made by Horizon with the Wylfa Newydd project. This includes the submission of the Site Licence Application, and successful completion of a third public consultation. 

The news has also been welcomed more widely: 

  • Albert Owen MP, Member of Parliament for Ynys Môn, said: “I welcome today’s news that the Generic Design Assessment for the UK Advanced Boiling Water Reactor has been completed. The four years of hard work and dedication is admirable. This is a significant milestone and I am pleased that the UK ABWR has met the very high standards of safety required by UK regulators. I look forward to continued engagement with the Wylfa Newydd project team and its onward development.”
  • Dennis Evans, Chair of the independent Wylfa Newydd Project Liaison Group, said: “I’m very pleased to note this significant milestone in the project’s development. Completion of the rigorous four-year assessment of the UK Advanced Boiling Water Reactor to the satisfaction of the UK Regulators, and within the timescale set by Hitachi-GE is notable and commendable. I look forward to seeing the final detailed proposals for the Wylfa Newydd development in due course, and congratulate the team in bringing the Generic Design Assessment to a satisfactory close.”
  • Guto Bebb MP, Parliamentary Under Secretary of State at the Wales Office, said: “New nuclear has a central role to play in our energy future, delivering secure, low carbon power and supporting jobs and economic growth. Helping to put Wales at the forefront of future technologies and clean growth projects are core objectives of our Industrial Strategy. We must however be absolutely sure that any nuclear reactor used in this country meets our rigorous safety standards. Today’s announcement is an important step forward for the Horizon Nuclear Power project at Wylfa Newydd on Anglesey which will bring thousands of jobs for the local area and new nuclear power to millions of homes across the UK.”
  • Ian Price, Director of CBI Wales, said: “Wylfa Newydd will bring huge business benefits across Wales and we therefore warmly welcome today’s announcement. Businesses on Anglesey and across North Wales are already hard at work on the project and today’s news is a big step towards even more opportunities for Welsh companies.”
  • Ken Skates AM, Cabinet Secretary for Economy and Transport, Welsh Government, said: “I am delighted that the Hitachi-GE UK ABWR technology has today successfully concluded Step 4 of the ONR’s Generic Design Assessment process. The completion of this final step to the original timetable is a significant achievement and I congratulate all involved in making this happen. We look forward to the Wylfa Newydd project making further significant strides in 2018”
  • Cllr Llinos Medi, Leader of the Isle of Anglesey County Council, said: “This is a key milestone for Hitachi-GE, Horizon Nuclear Power, and another important step forward in the Wylfa Newydd journey. The Office for Nuclear Regulation (ONR) is renowned as the most stringent regulator in the world and its approval following a comprehensive GDA assessment gives us confidence in the safety and security of the technology provided by Hitachi-GE. The Isle of Anglesey County Council will continue to engage with Horizon Nuclear Power. We are committed to working in partnership to ensure that the project benefits Anglesey and wider North Wales region.”
  • Rebecca Long Bailey MP, Shadow Secretary of State for Business, Energy and Industrial Strategy, said: “I welcome the announcement by Horizon Nuclear Power that they have completed the GDA process and move one step closer to delivery of this project. Nuclear is an important part of a balanced energy strategy to decarbonise the economy. Wylfa Newydd will be a key component of this energy strategy while creating thousands of highly skilled well paid jobs in parts of the country that sorely need them.”
  • Richard Harrington MP, Energy Minister at the Department for Business, Energy and Industrial Strategy, said: “Today’s announcement is a major milestone for the development of new innovative nuclear plants in the UK. As we set out in our Industrial Strategy, we are putting the UK at the forefront of future technologies which have the potential to create value and jobs across the UK. Horizon Nuclear Power’s nuclear technology is one example of this.”
  • Sarah Beacock, Chief Executive of the Nuclear Institute, said: “This is an important achievement for Hitachi-GE and all those that have worked on this exciting project. In completing the Generic Design Assessment (GDA) for the UK Advanced Boiling Water Reactor (ABWR) it further displays to the public, the high standards and behaviours of nuclear professionals working in the industry.” 
  • Tom Greatrex, Chief Executive of the Nuclear Industry Association, said: “The design approval of the UK ABWR is good news for the UK’s new nuclear programme and signals the conclusion of a thorough, rigorous and detailed process by the UK’s independent regulators, widely acknowledged as world class. With two thirds of UK power stations closing between 2010 and 2030, this is an important step in providing secure, reliable and low carbon nuclear power for the future, to homes, businesses and public services. The nuclear sector already accounts for £400 million of Welsh GDP. Future projects will build on this, creating highly skilled jobs and further economic benefit to the communities in which it will be built.”

Notes to editors:

  • The UK ABWR underwent a rigorous four-step Generic Design Assessment (GDA) by the Office for Nuclear Regulation (ONR), the Environment Agency (EA) and Natural Resources Wales (NRW) to scrutinise its suitability for use in the UK. The ONR has granted the UK ABWR a Design Acceptance Confirmation (DAC), whilst the EA and NRW granted a Statement of Design Acceptability (SODA).
  • GDA is the process by which the UK nuclear regulators assess the potential suitability of a design for development at an unspecified location in the UK, examining safety, environmental protection and security. Issue of a DAC and SoDA mark the successful completion of this process.
  • GDA of the UK ABWR began in April 2013. The process entailed detailed assessments and submissions across 20 topic workstreams, entailing a peak-team of well over 300 from Hitachi-GE and Horizon.
  • Horizon has worked closely with their reactor supplier Hitachi-GE throughout GDA, and is the site license applicant for the proposed developments. GDA does not in itself give permission to construct, and Horizon now begins a process of site specific safety and environmental applications – in parallel to that for their nuclear site license. Once all these permissions are achieved, Horizon can move to construction of Wylfa Newydd.
  • The regulators today published the DAC; SoDA; Assessment Reports for each topic (GDA Step 4); ONR Summary Assessment Report and EA & NRW Summary Decision Document. They have also completed publication of all RIs & ROs with resolution plans & closure letters at onr.org.uk/new-reactors/uk-abwr/index.htm
