Scope of supply
Scope of supply
Taishan Unit 2 - NI preparation works
A global agreement is signed with CGNPC, it encompasses actually four contracts signed in the framework of the Taishan Unit 1&2:
- Nuclear Island Engineering and Procurement,
- Fuel cores supply and
- the related technological transfers.
AREVA is responsible for the Nuclear Island design and procurement, and is leader of a consortium with two subsidiaries of CGNPC for procurement (CNPEC) and design (CNPDC), including the:
- Nuclear Island Engineering & Procurement (NI EP), Nuclear Steam Supply System (NSSS), and Balance of Nuclear Island (BNI)
- Design by a Joint Design Organization (JDO) including AREVA and CNPDC engineers, under AREVA's responsibility
- Procurement and delivery shared by AREVA and CNPEC including some localization in China for some specific components
- Digital control system:
> Safety Instrumentation and Control (I&C) and electrical system, engineering, and manufacturing
> Operational I&C, engineering, and manufacturing
- Supply of the two first fuel cores and seventeen reloads
- Supply fuel and enriched uranium during 15 years
TSNPC leads following activities:
- Overall project coordination, integration of the complete plant including Balance-of-plant systems and turbine island
- Setting-up and commissioning
- Civil works for the complete nuclear island and turbine island (with technical assistance by AREVA)
AREVA supply chain
Globally qualified industrial supply chain and pool of subcontractors: around 120 suppliers will be working for the consortium AREVA/CNPEC/CNPDC on the TSN 1&2 project.

End 2010, more than 1,500 AREVA employees and suppliers were working for the Taishan Project (835 in France, 385 in Germany and 315 in China). In the framework of the Nuclear Island Engineering contract, 25% of the global engineering workload is realized with a customer’s (CNPDC) subsidiary in China. As a result, a Joint Design Organization (JDO) is set-up in Shenzhen for the Taishan 1&2 project, gathering AREVA and CNPDC’s engineers under AREVA responsibility.
In 2011, more than 300 engineers are in charge of the detailed design work, mainly for piping and electrical activities.
In December 2009, AREVA and CGNPC created WECAN, a company responsible for engineering and procurement for the nuclear islands of the new plants to be built in China.
The EPR™ design is proceeding through a licensing process. This licensing process is being conducted in parallel with project execution (in particular on the basis of the nuclear island inputs from AREVA) under the TNPJVC’s responsibility, interfacing with the Chinese Regulatory Body, NNSA.
The PSAR (Preliminary Safety Analysis Report) was completed in August 2008, and then assessed by the safety body .
The construction permit was then granted in October 2009 for the First Concrete Dtae (FCD) to proceed.
