Unit 2 of the Taishan nuclear power plant will enter into commercial operation on Saturday the 7th of September 2019, following statutory functional test of continuous operation at full power for 168 hours, which started on Saturday the 30th of August at 17:15 local time. This step marks the achievement of all prerequisite conditions for the second reactor’s safe operation just nine months after Unit 1 was commissioned.
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 led by TNPJVC, a joint-venture founded by CGN (51%), EDF (30%) and the Chinese utility Guangdong Energy Group (19%). The EDF Group and its subsidiary Framatome supplied the EPR technology for the plant. The project capitalised on 35 years of strategic cooperation between EDF and CGN, as well as operating experience from the Flamanville 3 EPR and the complementarity between the French and Chinese nuclear sectors.
Experience acquired through the commissioning of the first reactor on 13 December 2018 allowed to reduce by 3 months the period between the fuel loading and the plant’s entry into commercial operation, whilst sustaining identical safety conditions. This performance demonstrates the potential to optimise future EPR construction sites. Since it was commissioned, reactor No.1 has achieved excellent operational results.
The Taishan project 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.
Jean-Bernard Lévy, the EDF Chairman and CEO stated: “Start-up of the world’s second EPR at the Taishan site, combined with the excellent operational performances achieved at Unit 1, are testament to the quality of the reactor design and confirm the industrial feasibility of projects undergoing development. The success of the Taishan project is the result of a long and fruitful cooperation between EDF and CGN and more widely in the French and Chinese nuclear sectors. Safe and competitive, EPR technology is an increasingly important asset to make the global energy mix totally carbon free.”

Key figures for the Taishan Nuclear Power Plant:
2 1750-MW EPR reactors, the most powerful in the world
The plant will be able to generate up to 24TWh of electricity per year, tantamount to the power consumed by 5 million Chinese users
The plant will prevent the emission of around 21 million tonnes of CO2 per year.
More than 200 French engineers were involved throughout the project’s duration
More than 15 000 workers were mobilised during the busiest periods of the construction phase
Nearly 800 people will be required to operate both reactors
Nearly 40 French companies were involved in the construction of the reactor. Revenue generated for the French sector is estimated at around €2.4 billion.
The site covers a surface area of 400 hectares.
