我国首个配置冷却塔的“华龙一号”核电机组全面启动建设

Core Points - The first "Hualong One" nuclear power unit with a cooling tower in China has successfully completed the first concrete pouring for the nuclear island, marking the full launch of the Shandong Zhaoyuan nuclear power project [1] - The project is located in Zhaoyuan City, Shandong Province, and is the tenth nuclear power base established by China General Nuclear Power Group, planning to build six "Hualong One" units [1] - Once all units are completed, the project is expected to generate an annual electricity output of 50 billion kilowatt-hours, meeting the annual electricity needs of approximately 5 million people, while significantly reducing coal consumption and carbon dioxide emissions [1] Project Features - 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 is the first application of secondary circulation cooling technology in the "Hualong One" units [1] - This design changes the direct cooling source from the sea to the atmosphere, utilizing atmospheric heat to dissipate excess heat from the conventional island, with seawater serving only as a supplementary water source [1] - The cooling tower allows for the recycling of cooling water, significantly reducing water head and energy consumption, and minimizing water loss, thereby enhancing cooling source safety [1] Safety Measures - The high-level water collection natural ventilation cooling tower can ensure the unit operates continuously for at least 2 hours without external water supply, providing a "buffer zone" for safe and stable shutdown under extreme conditions [2] - Additionally, the project is the first to equip the "Hualong One" with a nuclear-grade mechanical ventilation cooling tower, which has a large capacity water pool that can provide cooling for the reactor for at least 30 days in the absence of supplementary water [2]
