On September 11, all product tests and the post-test overhauling of the first AP1000 canned motor main pump jointly produced by Shenyang Blower Works Group Nuclear Pump Co., Ltd. and Harbin Electric Power Equipment Co., Ltd. were successfully completed.

The test data shows that all the performance parameters of the main pump meet the requirements of the main pump design specification, and the overall overhauling indicators meet the relevant requirements.

The success of this main pump test indicates that domestic enterprises have been fully equipped with the capability of manufacturing localized AP1000 canned motor main pumps, which provides strong guarantee for the supply of the localized main pumps of CAP series power plants.

Main pump is one of the key equipments of NPPs and plays an important role in the safe and reliable operation of NPPs reactor system.

State Nuclear Power Technology Corporation (SNPTC) is in charge of the introduction and assimilation of AP1000 technology. So far, four AP1000 units (Sanmen No. 1 and No. 2 units, Haiyang No. 1 and No. 2 units) of the self-reliant program of Gen III NP have all entered into the nuclear operation state. Sanmen No. 1 unit is expected to achieve commercial operation in the near future.
