Taishan 1&2 - China

AREVA is constructing two EPR™ reactors at Taishan site,in Guangdong province, China. This contract is the largest international commercial contract signed in civil nuclear history.
This project reaffirms AREVA’s global nuclear leadership and reinforces its presence in one of the most promising markets for the decades to come.

Thanks to the operating experience gained by AREVA’s teams on the two first-of-a-kind EPR™ reactors at Olkiluoto and Flamanville, the project schedule has been shortened by 40 months.

  • Resources

    Resources

    In 2012, more than 1,400 AREVA employees were working on the Taishan project, the majority of them based 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.

  • Licensing

    Licensing

    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.

    AREVA handed the Preliminary Report of Safety to CGNPC on August 22nd, 2008.

    The construction permit was then granted in October 2009 for the First Concrete Dtae (FCD) to proceed.
