CGN POWER(SZ:003816) Zhong Guo Zheng Quan Bao·2025-11-18 22:14Core Viewpoint - The successful completion of the first concrete pouring for the nuclear island of the "Hualong One" nuclear power unit at the Shandong Zhaoyuan Nuclear Power Project marks the full launch of the project's first phase, which is crucial for integrating clean energy in Shandong's energy development plan [1][2]. Group 1: Project Overview - The Zhaoyuan Nuclear Power Project plans to build six "Hualong One" units, with the notable innovation of incorporating a cooling tower for the first time [2]. - Once all units are operational, the project is expected to generate an annual electricity output of 50 billion kilowatt-hours, sufficient to meet the annual electricity needs of approximately 5 million people, while reducing standard coal consumption by about 15.27 million tons and cutting carbon dioxide emissions by around 46.2 million tons each year [1][2]. Group 2: Cooling Technology - The project features a high-level water collection natural ventilation cooling tower, standing at 203 meters with a water collection area of 16,800 square meters, which utilizes secondary circulation cooling technology [2][3]. - This cooling system allows the nuclear power plant to use atmospheric heat for cooling, significantly reducing water consumption and energy use while ensuring cooling source safety [2][3]. Group 3: Safety Measures - The high-level water collection cooling tower can maintain continuous operation of the unit for at least 2 hours without external water supply, providing a buffer for safe shutdown in extreme conditions [3]. - Additionally, a nuclear-grade mechanical ventilation cooling tower is included, capable of providing cooling for the reactor for at least 30 days without external water supply, enhancing cooling safety for the nuclear island [3]. Group 4: Construction and Digitalization - The construction of the cooling tower employs advanced techniques such as electric climbing molds and mechanized construction to enhance efficiency while ensuring safety [4]. - The project integrates 36 advanced construction technology solutions, including automated welding and digital applications for real-time monitoring, significantly improving construction quality and efficiency [4]. Group 5: Comprehensive Utilization of Nuclear Energy - The project is also focused on the comprehensive utilization of nuclear energy, contributing to clean heating initiatives in the Shandong Peninsula and improving ecological conditions [5][6]. - Each unit can provide up to 1,000 tons of steam per hour for heating, covering an area of over 15 million square meters, with plans to expand into industrial steam, nuclear hydrogen production, and seawater desalination [6].
