A joint venture

China General Nuclear Power Corporation (CGN) and EDF have created a joint venture company, called General Nuclear System Limited (GNS), to undertake the Generic Design Assessment (GDA) process for the UK HPR1000 nuclear reactor technology.

In October 2016, we wrote to the Department for Business, Energy and Industrial Strategy (BEIS) requesting entry to the GDA process for the UK HPR1000 reactor design. The request was accompanied by a report providing evidence of our readiness and, in January 2017, we formally entered Step 1 of the GDA process.

CGN and EDF have been working together for more than 30 years on a range of projects, including nuclear development and construction in China. We formed an industrial partnership in the UK to build the Hinkley Point C nuclear power station in Somerset and to develop Sizewell C (Suffolk) and Bradwell B (Essex).

Together we bring a wealth of experience in developing nuclear power stations across the world, as well as proven safety and security records. This long-standing cooperation and extensive capability in the nuclear industry will bring numerous benefits to the UK.

GNS acts on behalf of the three joint requesting parties: China General Nuclear (CGN), EDF and General Nuclear International (GNI). For practical purposes GNS is referred to as the ‘UK HPR1000 GDA Requesting Party’.

The CGN Group is the owner and operator of both nuclear power and renewable energy plants. As a holding company, China General Nuclear Power Corporation, has 41  subsidiaries with over 35,000 employees worldwide, providing customers with professional integrated energy solutions, including nuclear power plant design, construction, operation, maintenance and nuclear fuel supply. CGN is the largest nuclear power operator in China and the largest nuclear power constructor worldwide.

CGN currently has 20 units in operation with a capacity of 21.47 GW. There are nine units currently under construction by CGN with a capacity of 10.24 GW. Its NPP new build projects account for about 17% of the worldwide volume.

As a global leader in low-carbon energy, the EDF Group covers every sector of expertise, from generation to trading and transmission grids. EDF builds on the expertise of its people, its R&D and engineering skills, its experience as a leading industry operator and the attentive support of its customers to deliver competitive solutions that successfully reconcile economic growth with climate protection.

As the world’s largest nuclear power generator, with a global installed capacity of 72.9GW, EDF Group has extensive experience of building and running nuclear power stations. EDF Group has also built up a large nuclear power generation capacity in France, where the company’s 58 plants have a total installed capacity of 63.1GW. France is now the second largest generator of nuclear power in the world, after the United States.

In the UK, EDF Energy is the largest producer of low-carbon electricity, and produces around one-fifth of the country’s electricity from its nuclear power stations, wind farms, coal- and gas-powered stations, and combined heat and power plants. The company currently operates 15 nuclear reactors in the UK, with a total installed capacity of just under 8.8GW.

EDF Energy is committed to helping secure our energy supplies for the future by investing in an energy mix that balances the needs of low-carbon emissions, security of supply, and affordability.
