项目概况
PROJECT PROFILE
大亚湾核电站（Daya Bay Nuclear Power Plant）由广东核电投资有限公司和香港核电投资有限公司合资建设与运营，隶属中国广核集团管辖，拥有两台百万千瓦级压水堆机组，所生产电力80%供应香港，20%供应广东。电站于1987年开工建设，1994年2月，1号机组投入商业运行；同年5月，2号机组投入商业运行。 此后，在大亚湾核电站之侧又建设了岭澳核电站，两者共同组成一个大型核电基地。大亚湾核电站是中国大陆第一座大型商用核电站，也是中国大陆首座使用国外技术和资金建设的核电站。2016年11月，大亚湾公司获得第十六届全国质量奖。截至2024年6月30日，大亚湾核电基地六台机组累计上网电量9597亿度。 2024年2月1日，中广核集团表示，大亚湾核电站安全投运30年，为香港供电累计达3104亿度。2025年4月29日，中广核广东大亚湾核电基地六台机组累计上网电量突破1万亿千瓦时。
The Daya Bay Nuclear Power Plant is a joint venture between Guangdong Nuclear Power Investment Co., Ltd. and Hong Kong Nuclear Power Investment Co., Ltd., and is under the jurisdiction of China General Nuclear Power Group (CGN). It has two 1,000 MW pressurized water reactor units, supplying 80% of its electricity to Hong Kong and 20% to Guangdong. Construction began in 1987, and Unit 1 commenced commercial operation in February 1994; Unit 2 followed in May of the same year. Subsequently, the Ling Ao Nuclear Power Plant was built adjacent to the Daya Bay plant, forming a large nuclear power base. The Daya Bay plant was the first large-scale commercial nuclear power plant in mainland China and also the first nuclear power plant in mainland China to utilize foreign technology and funding. In November 2016, Daya Bay Company received the 16th National Quality Award. As of June 30, 2024, the six units at the Daya Bay nuclear power base had generated a cumulative 959.7 billion kWh of electricity. On February 1, 2024, CGN (China General Nuclear Power Group) announced that the Daya Bay Nuclear Power Plant had been operating safely for 30 years, supplying Hong Kong with a cumulative total of 310.4 billion kilowatt-hours of electricity. On April 29, 2025, the six units at CGN's Guangdong Daya Bay Nuclear Power Base had cumulatively generated over 1 trillion kilowatt-hours of electricity.

施工范围
SCOPE OF CONSTRUCTION
大亚湾核电站共6台机组在运，包含大亚湾核电站1/2号机组、岭澳核电站1/2号机组、岭东核电站3/4号机组。在6台机组中有65台冷制冷机组，其中包含水冷机和风冷机；6台机组包含空调约2000台，其中有水冷空调机约20台、多联机组约25套、分体挂机分体柜机约1450台、风机盘管约260台。目前上述的制冷机、空调、风机盘管均在维护保养范围内，工作内容大体分为以下四种：
1、制冷机/空调设备状态的巡检、运行状态核实、运行参数核实；
2、制冷机/空调的预防性季度、半年、年度、四/五年检查；
3、设备突发新增缺陷的纠正性检查处理；
4、计划规划性的空调更换、新增安装。
The Daya Bay Nuclear Power Plant has six operating units, including Daya Bay Units 1 and 2, Ling'ao Units 1 and 2, and Lingdong Units 3 and 4. These six units comprise 65 refrigeration units, including water-cooled and air-cooled units; and approximately 2,000 air conditioning units, including about 20 water-cooled air conditioners, about 25 multi-split air conditioning units, about 1,450 split-type wall-mounted units and split-type cabinet units, and about 260 fan coil units. Currently, all of the aforementioned refrigeration units, air conditioners, and fan coil units are under maintenance. The work mainly falls into the following four categories:
1. Inspection of the status of refrigeration/air conditioning equipment, verification of operating status, and verification of operating parameters;
2. Preventive quarterly, semi-annual, annual, and four/five-year inspections of refrigeration/air conditioning units;
3. Corrective inspection and handling of newly discovered equipment defects;
4. Planned replacement and installation of new air conditioning units.
