  • Resources

    Resources

    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.

  • 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.

    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.
