The first of two EPR reactors at China’s Taishan nuclear power plant enters into commercial operation
On Friday 14th of December 2018, CGN and EDF announced, at a joint press conference in Beijing, that unit 1 of Taishan nuclear power plant had become the world’s first EPR to enter into commercial operation. This last milestone was reached on Thursday 13th of December 2018 after the final statutory functional test of continuous operation at full power for 168 hours. The successful outcome of this test marks the achievement of all prerequisite conditions for the reactor’s safe operation.
Comprising two 1750-MW EPR reactors, Taishan nuclear power plant is the biggest cooperation project to have taken place between China and France in the energy sector. Taishan’s two reactors are capable of supplying the Chinese power grid with up to 24 TWh of CO2-free electricity a year, tantamount to the annual electricity consumption of 5 million Chinese users, whilst at the same time preventing the emission of 21 million tons of CO2 a year.
The Taishan project is being led by TNPJVC, a joint venture founded by CGN (51%), EDF (30%) and a regional Chinese utility called Yuedian (19%). The EDF Group and its Framatome subsidiary supplied the third-generation EPR technology, which meets the highest international safety standards. EDF also contributed operating experience from the construction of its Flamanville-3 EPR. The use of this operating experience was a crucial factor in successfully completing the initial phases of the Taishan 1 construction project. CGN, which oversaw the construction phase of the project, capitalised on more than 30 years of experience in the construction of nuclear power plants.
Taishan 1 has benefited from 35 years of strategic cooperation between EDF and CGN, which started with the construction of China’s very first commercial nuclear power plant at Daya Bay. Both companies also took advantage of the complementary relationship between the French and Chinese nuclear industries, thereby increasing their knowledge base and offering new business opportunities.
Taishan 1 is providing EPR reactors around the world with its experience in project management and technological expertise. The first reactors to benefit from this experience are the two Hinkley Point C units currently being built in the UK. The two companies are also partners in the Sizewell C EPR project, as well as in the Bradwell B project which is based on Hualong technology.
He Yu, Chairman of China General Nuclear Power Group: “Taishan 1’s entry into operation marks the accomplishment of the task set by the Chinese and French heads of state. As the world’s first EPR project, Taishan offers valuable lessons and solutions for the construction of similar reactors worldwide and it will play a demonstrative and supportive role in the joint construction of the Hinkley Point C project in the UK by CGN and EDF.”
Jean-Bernard Lévy, EDF Chairman and Chief Executive Officer: "The commissioning of Taishan 1, the world’s first EPR to enter into commercial operation, is a key achievement for the entire French nuclear industry as it demonstrates its capacity to develop this third-generation nuclear technology in line with the highest safety and quality standards. EPR is a major asset in addressing the challenge facing many countries: reconciling the growth of electricity demand with the need to reduce carbon dioxide emissions. The Taishan project also illustrates our approach to developing EPRs worldwide, in cooperation with valued partners such as CGN.”
