Core Viewpoint - The construction of the first unit of the Shandong Zhaoyuan Nuclear Power Project, featuring the "Hualong One" reactor, has officially commenced, marking a significant step in China's nuclear energy development [1][3]. Project Overview - The Zhaoyuan Nuclear Power Project plans to build six "Hualong One" nuclear reactors, with an expected annual electricity generation of 50 billion kilowatt-hours, sufficient to meet the needs of approximately 5 million people [3]. - The project aims to significantly reduce coal consumption by about 15.27 million tons and cut carbon dioxide emissions by approximately 46.2 million tons annually, equivalent to reforesting over 110,000 hectares [3]. Technological Innovations - The project features a high-level natural ventilation cooling tower, standing at 203 meters with a water collection area of 16,800 square meters, which utilizes secondary circulation cooling technology for the first time in "Hualong One" reactors [3][4]. - This cooling system replaces seawater with atmospheric air as the primary cooling source, enhancing water recycling and reducing energy consumption [4]. Safety and Efficiency Enhancements - The cooling tower can maintain continuous operation for at least 2 hours without external water supply, providing a buffer for safe shutdown in extreme conditions [5]. - The project also includes a nuclear-grade mechanical ventilation cooling tower, which can provide cooling for the reactor for at least 30 days without external water supply, further ensuring safety [5]. Construction Techniques - Advanced construction techniques such as electric climbing molds and automated welding are being employed to enhance construction efficiency while ensuring safety [7]. - The project incorporates digital applications for real-time monitoring and quality management, transitioning towards intelligent construction methods [7]. Comprehensive Utilization of Nuclear Energy - The project is also focusing on the comprehensive utilization of nuclear energy, with plans for nuclear heating that can provide up to 1,000 tons of steam per hour, covering an area of over 15 million square meters [8]. - Future expansions may include industrial steam supply, nuclear hydrogen production, and seawater desalination [8].
