On September 11th, the first AP1000 shielded motor main pump jointly produced by Shenyang Blower Group Nuclear Power Pump Co., Ltd. and Harbin Electric Power Equipment Co., Ltd. (hereinafter referred to as Harbin Electric Power Equipment Co., Ltd.) successfully completed all products in Shengu Nuclear Power. After the test and the test, the test data shows that the performance parameters of the main pump meet the requirements of the main pump design specification. The overall demolition inspection indicators meet the relevant requirements. The success of the main pump test marks the domestic enterprise. It has fully equipped the localized manufacturing capability of the AP1000 shielded motor main pump, which provides a strong guarantee for the domestic supply of the main pump of the CAP series power station.
The main pump is one of the key equipments of the nuclear power plant and plays an important role in the safe and reliable operation of the nuclear power plant reactor system. The AP1000 reactor coolant main pump uses a high power shielded pump with a high moment of inertia flywheel, due to its design, analysis and calculation, manufacturing, The inspection and test technology is difficult and demanding. The whole process of the main pump from technology transfer negotiation, introduction of technology, digestion and absorption to localized manufacturing has been highly concerned by the industry.
Under the support of the national large-scale nuclear voltage water reactor, the submerged nuclear power plant and Harbin Electric Power installed on the basis of introducing, digesting and absorbing AP1000 shielded motor main pump technology, and carried out localization of a number of key manufacturing technologies. ASME forensics, process validation, key component manufacturing and other milestone mission nodes, the final completion of the main pump manufacturing, assembly, testing and dismantling work.
