CGN POWER(SZ:003816) Zhong Guo Zheng Quan Bao·2025-11-18 15:37Core Viewpoint - The construction of the first "Hualong One" nuclear power unit with a cooling tower in China has officially commenced, marking a significant step in the Shandong energy development plan and contributing to the region's green and low-carbon transformation [1][2]. Group 1: Project Overview - The Shandong Zhaoyuan Nuclear Power Project's Unit 1 has successfully completed the first concrete pouring for the nuclear island, indicating the full launch of the project's first phase [1]. - 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]. Group 2: Innovative Features - The project features a 203-meter high natural ventilation cooling tower with a water collection area of 16,800 square meters, marking the first application of secondary circulation cooling technology in the "Hualong One" units [2]. - This design shifts the primary cooling source from seawater to atmospheric air, allowing for the recycling of cooling water and significantly reducing energy consumption and water loss, thereby enhancing cooling source safety [2]. Group 3: Safety Measures - The high-level water collection natural ventilation cooling tower can ensure continuous operation of the unit for at least 2 hours even under conditions of lost external water supply, providing a buffer for safe shutdown in extreme situations [2]. - Additionally, the project incorporates a nuclear-grade mechanical ventilation cooling tower, which can maintain cooling for the reactor for at least 30 days without external water supply, further strengthening the cooling assurance for the nuclear island [2]. Group 4: Comprehensive Utilization of Nuclear Energy - The project is also focused on the comprehensive utilization of nuclear energy, aiming to integrate into the clean heating network of the Jiaodong Peninsula in Shandong Province, thereby supporting clean heating and ecological improvement in northern regions [3]. - 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 in the future [3].
