    Recently, China's first AP1000 third-generation nuclear power plant in the last main pump durability test, the impeller appeared slightly cracked
    .
    At present, the US side is issuing a report
    on the rift.

    The AP1000 nuclear power main pump, designed and manufactured by EMD in the United States, began the third engineering and endurance test on February 25, 2015, and successfully completed the test on May 20, which lasted 85 days
    .
    626 starts and stops under various working conditions
    .
    After the test, EMD disassembled and tested
    the components of the main pump.
    The main pump design and manufacturing technology is one of the main contents of the technical transfer of
    AP1000 by the American EMD company.
    Relevant people confirmed that "in the main pump test, there was a slight crack in the position of the impeller, about 10 mm to 12 mm
    in length.
    The main pump is not a nuclear safety device and does not address the safety
    of future nuclear power plant operations.

    When asked how the cracks will be handled, the person said, "Usually a new impeller is used or the problem impeller is
    repaired.
    The use of new impellers requires a long procurement time
    .

    It is understood that according to the original plan, if the test is successful, the main pump will be transported to Zhejiang Sanmen Nuclear Power Plant for pre-installation preparation and testing
    .
