现场一声令下,

中核集团旗下中国核电(股票代码:601985)投资控股中核海南多用途模块式小型堆科技示范工程
玲龙一号反应堆核心模块

被高高吊起,向着核岛方向移动。

吊装成功!

压力容器、蒸发器等关键设备一步到位

玲龙一号全球首堆的安装工作步入高峰期

这是玲龙一号核岛设备安装关键路径上的第一个里程碑节点,是核反应堆模块化制造和安装的一次“首秀”,代表全球核能小型化迈出了历史性一步,标志着我国在模块式小型堆建造上走在了世界前列,也是中核集团把主题教育与重大工程建设结合起来,扎实推进主题教育在以学铸魂、以学增智、以学正风、以学促干方面走深走实、见行见效的生动实践。

为确保工程质量全面可控,项目团队统筹谋划设备验收、出厂、转运、接收、吊装工作,在监管当局全程严格监督下,海监、设备厂商、现场建设团队通力配合,有效克服了天气复杂多变、设备稳定性要求高、首堆经验缺乏等多种困难,终于达成了“充分准备,一次成功”的目标。

玲龙一号是中核集团积极贯彻落实习近平总书记和党中央关于加快建设科技强国、实现科技自立自强的重要指示和决策部署的重要成果,是中核集团积极践行国家创新驱动发展战略的重要实践,是继华龙一号后我国核电自主创新的重大成果,填补了国内空白,具有广阔的全球市场前景,成为又一张靓丽的“国家名片”。
此次吊装的玲龙一号反应堆核心模块也被称作“玲龙之心”,是玲龙一号的核心部件,由中核集团中国核动力研究设计院自主设计和采购,中国第一重型机械股份公司承制,是100%的“中国制造”,集成了压力容器、蒸发器、主泵接管,并取消了主管道。其中,蒸汽发生器是内置在反应堆压力容器里的,吊装前,蒸汽发生器就已经在工厂与反应堆压力容器完成了组焊,是制造难度最高、最具代表性的“工厂化预制、模块化制造”核电主设备,其设计创新既提高了核电站安全性和可靠性,又极大地缩短了工期,提高了经济性。
小型堆因其安全性、部署灵活性及多用途等方面的独特优势,在新一轮核能技术变革和国际产业竞争中的作用日益凸显。据国际原子能机构(IAEA)统计,全球范围内正在开发的小型堆技术有超过80种,美、俄、英、日、韩等核电大国均将小型堆技术列入国家战略。玲龙一号是中核集团在成熟压水堆核电站和核电技术的基础上开发的具有自主知识产权的创新型核反应堆,是全球首个通过IAEA通用安全审查的小型模块化压水反应堆。同时,中核集团积极响应IAEA的小堆倡议,参与了IAEA首个小堆用户需求文件编制工作,为模块化小型堆发展贡献中国智慧。
今年9月,小堆技术发展和应用及用户需求和发展跨地区研讨会将在海南举办,届时玲龙一号将面向全球进行展示。


自设计之初,玲龙一号就不止于发电,还具有热电联供、水电联供、城市区域供热、海水淡化、工业工艺供热、自备电厂等多用途。作为高安全的分布式清洁能源,可类似常规燃煤热电厂,靠近城镇及工业园区部署,让核能“贴近城市、靠近用户”成为可能。
海南核电多用途模块式小型堆科技示范工程于2021年7月13日在海南开工建设,由中国核电工程公司总承包,中核二二负责土建施工,中核五公司负责设备安装,是全球首个建造的陆上商用模块化小型压水堆。建成投运后,预计每年发电量可达10亿度,可满足海南52.6万户家庭用电需求。同时,每年可减少二氧化碳排放量约88万吨,相当于一年植树750万棵。不仅将以稳定可靠的清洁能源助力国家“双碳”目标实现和海南“清洁能源岛”建设,更将以先进反应堆技术的示范效应,推动世界核能的发展。



World's first! 

"The Heart of Linglong One" in place

On August 10th, the core module of the Linglong One reactor, a multi-purpose modular small reactor in Hainan, a subsidiary of China National Nuclear Corporation (CNNC), was lifted and moved towards the nuclear island. Pressure vessel, evaporator and other key equipment were installed in one step, marking the peak phase of Linglong One’s installation.

This is the first milestone of the installation of Linglong One nuclear island. It marks the debut of modular manufacturing and installation of nuclear reactor modules, representing a historic step of global nuclear miniaturization and highlighting China's leading position in the modular manufacturing of small pressurized reactor units.

The core module, also known as "the heart of Linglong One", is Linglong One’s core components. It integrates pressure vessel, evaporator, and primary pump receiver, and removes the main pipeline. The steam generator is inside the reactor pressure vessel. Before the lifting, the steam generator already undergone joint welding with the reactor pressure vessel at the factory, effectively integrating the "lungs" and "heart" of the nuclear power plant. It is the most challenging and representative nuclear power main equipment featuring "factory prefabrication and modular manufacturing" processes. The design and construction of Linglong One are revolutionary and groundbreaking. Modular construction is its most prominent feature. Through standardized design, single module production, and mass production, it shortens the construction period and reduces costs while improving safety. The modular small reactor has a simplified system and small size, which is convenient for transportation and operation. It allows flexible adjustments and construction according to users' requirements, resulting in significant economic benefits.

The Hainan Nuclear Power Multi-purpose Modular Small Reactor Technology Demonstration Project is the world's first commercial land-based small modular pressurized water reactor. Upon its operation, it is expected to generate one billion kilowatt-hours of electricity per year, which could meet the needs of 526,000 households and is equivalent to reducing around 880,000 tons of CO2 emissions or planting 7.5 million trees. With its stable and reliable clean energy supply, it will contribute to China’s carbon peaking and carbon neutrality goals and the construction of a "clean energy island" in Hainan, and drive the development of nuclear energy worldwide.
