Horizon Nuclear Power (HNP), owned by Hitachi Ltd (Hitachi), is planning to construct the Wylfa Newydd nuclear power station project, formerly known as Wylfa B in North Wales, the UK.

The project involves the construction of a 2,700MW nuclear power plant with four Advanced Boiling Water Reactors (ABWRs) on 254ha of land.

The project includes the construction of a powerhouse, a substation, steam generators and reactor coolant pumps, a marine off-loading facility (MOLF), cooling water intake and outfall tunnels, electricity transmission infrastructure, interim waste storage facilities, access roads, administration offices and related facilities.

In July 2010, Frazer-Nash has been awarded a five-year framework contract for the provision of regulatory and licensing services.

Two reactor designs, UK-EPR designed by Areva and EDF, and AP1000 designed by Nuclear Power Delivery UK, a consortium of Westinghouse, Laing O'Rourke, Shaw Group and Toshiba, were assessed.

In August 2010, HNP signed contracts with Areva and Nuclear Power Delivery UK consortium for preparatory design studies, however, later contract was canceled.

HNP had planned to submit a planning application to the Infrastructure Planning Commission (IPC) in 2012 after the completion of public consultation. However, in March 2012, the project was put on hold due to the financial issues.

In March 2012, HNP joint venture was then put up for sale. Three consortia showed interest in acquiring the joint venture. The three consortia were as follows: a consortium of Areva and China Guangdong Nuclear Power Holding Co (CGNPC); Westinghouse and China’s State Nuclear Power Technology Corporation (SNPTC) consortium; GE Hitachi consortium.

In October 2012, Hitachi Ltd bought HNP joint venture. Hitachi completed the acquisition of HNP in November 2012 and in early 2013, Hitachi applied for a license to develop the project.

In May 2013, Hitachi and GE signed agreements with the Office for Nuclear Regulation and the Environment Agency for the generic assessment of Hitachi's ABWR reactor design.

On May 15, 2013, FEED contract was awarded to Hitachi-GE. Hitachi-GE supports in the site development work, assess the construction timetable, public consultations and support the supply chain development strategy.

On December 4, 2013, AMEC, Atkins, Cavendish Nuclear signed a contract to provide engineering and related technical services.

On December 17, 2013, Jacobs Engineering Group Inc was awarded a contract by HNP. Under the terms of the contract, Jacobs will provide development and planning, engineering, environmental permitting and waste management, and project management support.

In January 2014, Hitachi-GE submitted ABWR design for Generic Design Assessment (GDA).

In March 2014, Structural Soils Ltd has been appointed as the site investigation contractor to undertake the study of ground conditions, which will help in the more detailed planning of the preferred site layout.

In March 2014, HNP had initiated detailed ground investigation studies.

In July 2014, DECC has provisionally approved the planned reactor from Hitachi-GE for the project and a public consultation on the decision was invited till October 2014.

In January 2015, the project secured technology permit.

SP Energy Networks (SPEN) a part of Scottish Power group will install 6km of 132,000-volt underground cable to divert the existing circuits and make way for the nuclear power station.

In October 2015, Office for Nuclear Regulation (ONR) has completed Step 3 of the GDA.

In May 2016, Menter Newydd, a joint venture formed by Hitachi Nuclear Energy Europe, Bechtel Corporation, and JGC Corporation has been appointed as EPC contractor.

On July 7, 2016, the Japan Atomic Power Company (JAPC) was appointed as a technical consultant.

On August 31, 2016, HNP commenced second public consultations and completed on October 25, 2016.

On December 12, 2016, Environment Agency and Natural Resources Wales commenced design consultations on their assessment of power station design from Hitachi-GE, part of GDA process and lasts until March 3, 2017.

HNP will submit a planning consent application in 2018 and will commence the site preparatory works by the end of 2017. The main construction works are scheduled to commence in 2019, the first reactor commercial operation is scheduled in the third quarter of 2020 and the entire project is expected to complete in 2025.

Final stage GDA process is underway and scheduled for completion in December 2017. Hitachi-GE's ABWR reactors also need to be approved by the Office for Nuclear Regulation.
