Deaerator in Place for Unit 1 Conventional Island of Huaneng Shidao Bay Nuclear Power Expansion Project

Recently, the deaerator for Unit 1 conventional island of Phase I Expansion Project of Huaneng Shidao Bay Nuclear Power Station, undertaken by PowerChina Nuclear Engineering Company, was successfully hoisted and placed into position, marking a key milestone in the installation of conventional island equipment for the unit and creating conditions for subsequent turbine equipment installation, piping layout, and system commissioning. The Huaneng Shidao Bay Nuclear Power Base currently hosts a high-temperature gas-cooled reactor demonstration project, the world's first fourth-generation nuclear power plant to achieve commercial operation. The Phase I Expansion Project plans to build two Hualong One units, third-generation nuclear power units independently developed by China, each with a capacity of 1.225 million kilowatts. Upon completion, the project is expected to provide approximately 20 billion kilowatt-hours of clean electricity annually, reduce standard coal consumption by 5.78 million tons, and cut carbon dioxide emissions by 14 million tons.
