"Guohe 1", also known as CAP1400, is an advanced large pressurized water reactor with independent intellectual property rights developed based on the introduction, digestion, and absorption of internationally advanced third-generation nuclear power technologies, and supported by the national key projects for PWR power plants. It features high safety factors and superior economic performance. The development of "Guohe 1" has established an internationally advanced independent innovation system and industrial chain supply system for third-generation nuclear reactors. It has filled several technological and process gaps in China's nuclear power industry and driven the upgrading and transformation of China's nuclear power industry and technology. In line with national strategies, Harbin Electric Corporation actively developed and manufactured key equipment for the "Guohe 1" reactor, including the main canned motor pump motor, steam generator, passive residual heat removal heat exchanger, turbine generator set, high-pressure heater, and deaerator.
