CGN POWER(SZ:003816) Mei Ri Jing Ji Xin Wen·2025-11-18 09:21Core Viewpoint - The successful completion of the first concrete pouring for the nuclear island of the Shandong Zhaoyuan Nuclear Power Project marks the full launch of the first phase of construction for China's first "Hualong One" nuclear power unit equipped with a cooling tower [1]. Group 1: Project Overview - The Shandong Zhaoyuan Nuclear Power Project is the tenth nuclear power base established by China General Nuclear Power Group (CGN) in the country, with plans to build six "Hualong One" nuclear units [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 carbon dioxide emissions by approximately 46.2 million tons [1]. Group 2: Technological Innovations - The project features a high-level natural ventilation cooling tower, standing at 203 meters with a splash area of 16,800 square meters, which is a first for the "Hualong One" units [2]. - The cooling tower replaces the conventional cooling source from the sea to the atmosphere, allowing for the recycling of cooling water and significantly reducing water head and energy consumption, thereby ensuring the safety of the cooling source [2]. - The innovative secondary circulation cooling technology allows the cooling tower to maintain continuous operation of the unit for at least 2 hours under special conditions without external water supply, providing a buffer for safe and stable shutdown in extreme situations [2]. - Additionally, the project includes a nuclear-grade mechanical ventilation cooling tower, which can provide cooling for the reactor for no less than 30 days in the absence of supplementary water, further enhancing the cooling assurance for the nuclear island [2].
