Before the development of Chongqing Water Pump Factory Co. Ltd. and Chinese Guangdong Nuclear Power Group Co., combined with the three generation PWR nuclear power plant in Hualong one technology of nuclear safety grade two medium pressure safety injection pump (referred to as "medium pressure safety injection pump"), the three generation PWR nuclear power plant in Hualong one technology of nuclear safety three emergency pump (referred to as the "emergency boron boron pump"), through the identification of the national nuclear power group of senior experts.

       The expert group, jointly organized by the Federation of Chinese machinery industry and China General Machinery Industry Association Chinese Academy of Engineering Ye Qizhen as a leader, more than 40 domestic nuclear power industry experts agree: emergency boronation pump to fill the gap, at the international advanced level; medium pressure safety injection pump to achieve the international advanced level of similar products.

      At present, the three generation nuclear power "Hualong No. 1" technology is one of the advanced nuclear power technologies with independent intellectual property rights in China. One of the most prominent features is that the safety factor of nuclear power reactor operation safety has been increased.

      The emergency pump boron identification, its main function is to, in the nuclear power plant accident, injection of high concentration of boric acid medium to high pressure reactor system, to reduce the reaction speed, slow reactor heat output reactor, so as to improve the safety of nuclear power plant. The main function of the medium pressure injection pump is to inject cooling water into the safety injection system of the nuclear power plant during the accident of the nuclear power plant, and realize the cooling function of the core system of the nuclear power plant.

     Group of experts believe that the two types of nuclear power unit pump through the identification of China's nuclear power to go abroad to add momentum. Previously, similar equipment has been dependent on imports, the two types of nuclear power plants to achieve domestic, will change this situation, and the price is only about 50% of similar imports.
