‘Linglong One’ (ACP100) is the world’s first small modular pressurized water reactor to pass the International Atomic Energy Agency (IAEA) safety review. Independently developed by China National Nuclear Corporation (CNNC), it recently completed its non-nuclear tests at the global demonstration project site in Changjiang, Hainan Province. This milestone confirms that all primary and auxiliary systems function as designed—without nuclear fuel—paving the way for subsequent fuel loading and grid connection.Non-nuclear testing is a critical phase in nuclear power plant construction, verifying the performance of key systems such as the reactor coolant system, instrumentation and control systems, and safety protection mechanisms under simulated operating conditions. The successful completion of these tests not only validates the reliability and safety of Linglong One’s design but also highlights China’s growing innovation capabilities in advanced small modular reactor (SMR) technology.Designed for multiple applications—including urban heating, seawater desalination, and power supply for remote islands—Linglong One offers flexibility, shorter construction timelines, and enhanced safety features. Its progress represents a promising low-carbon energy solution for both China and the global community, supporting efforts to achieve carbon peak and carbon neutrality goals.
“玲龙一号”（ACP100）是全球首个通过国际原子能机构（IAEA）安全审查的小型模块化压水堆，由中国核工业集团有限公司自主研发。近日，“玲龙一号”全球首堆——位于海南昌江的示范工程顺利完成非核试验，标志着该反应堆系统在不使用核燃料的情况下，已全面验证其主系统和辅助系统的功能与性能，为后续装料和并网发电奠定了坚实基础。非核试验是核电站建设过程中的关键节点，主要测试反应堆冷却剂系统、仪控系统、安全保护系统等在模拟运行工况下的响应能力。此次试验的成功，不仅验证了“玲龙一号”设计的可靠性与安全性，也体现了中国在先进小型堆技术领域的自主创新能力。作为多用途小型堆，“玲龙一号”可应用于城市供热、海水淡化、海岛供电等多种场景，具有部署灵活、建设周期短、安全性高等优势。“玲龙一号”的顺利推进，将为中国乃至全球提供一种新型低碳能源解决方案，助力实现碳达峰与碳中和目标。
