作为国家重点能源项目，田湾核电7、8号机组肩负着优化国家能源结构的重任。两台机组预计分别于2026年、2027年投运，每年可提供清洁电力超过700亿千瓦时，相当于每年减少二氧化碳排放5740万吨，对构建清洁低碳、安全高效的现代能源体系，实现“双碳”目标具有重要作用。

田湾核电7、8号机组共用一座除盐水厂房。除盐水生产系统的功能是将生产水经超滤、反渗透膜及离子交换处理后，向核岛、常规岛和BOP等用户提供符合水质和水量要求的除盐水。在系统安装调试阶段，青岛双瑞积极协调解决设计、施工、调试等领域遇到的难题，助力工程有序推进，整体工期低于同行业水平30%，最终实现了水质稳定、供水充足的目标，为机组的长期稳定运行奠定了坚实基础，打造了行业标杆。

公司自2008年开始进入海水淡化行业，目前全面掌握国际领先的膜法海水淡化系统的设计、制造、安装、调试和运行技术，具备海水淡化工程总承包的能力，能够为客户提供一站式解决方案。凭借优异的全产业链资源整合能力、强大的现场执行能力和国际标准的项目管理体系，公司受到了国内核电客户长期的信赖，目前共拥有60余台核电机组的供货工程业绩。

As a national key energy project, Tianwan Nuclear Power Unit 7 and 8 shoulder the heavy responsibility of optimizing the national energy structure. The two units are expected to be put into operation in 2026 and 2027, respectively, and can provide more than 70 billion KWH of clean electricity per year, equivalent to reducing carbon dioxide emissions by 57.4 million tons per year, which plays an important role in building a clean, low-carbon, safe and efficient modern energy system and realizing the "double carbon" goal.

Tianwan Nuclear Power Plant Unit 7 and 8 share a desalinized water plant. The function of the demineralized water production system is to provide demineralized water that meets the water quality and quantity requirements to users such as nuclear Island, conventional Island and BOP after the production water is treated by ultrafiltration, reverse osmosis membrane and ion exchange. In the system installation and commissioning stage, Qingdao Shuangrui actively coordinated to solve the problems encountered in the design, construction, commissioning and other fields, to help the orderly progress of the project, the overall construction period is 30% lower than the industry level, and finally achieved the goal of stable water quality and adequate water supply, laying a solid foundation for the long-term stable operation of the unit and creating an industry benchmark.

Since 2008, the company has entered the desalination industry. At present, it has fully mastered the design, manufacturing, installation, commissioning and operation technology of the internationally leading membrane desalination system, and has the capacity of general contracting of desalination projects, so as to provide customers with one-stop solutions. With excellent resource integration ability of the whole industrial chain, strong on-site execution ability and international standard project management system, the company has been trusted by domestic nuclear power customers for a long time, and has a total of more than 60 nuclear power units supply engineering performance.
