On December 11, Moon Environment Technology Co., Ltd. (000811) responded to investor inquiries, stating that recent signals indicate accelerated national nuclear power construction. In this field, the company focuses on core scenarios such as nuclear island cooling and nuclear heating, developing a series of innovative technologies including nuclear island cooling, waste heat recovery, passive air coolers inside containment vessels, simultaneous water-heat production and delivery, and large-temperature-difference long-distance nuclear heating. These advancements provide robust technical support and solutions for the safe and stable operation of nuclear power plants and the efficient utilization of clean energy.
Domestically, the company has served nuclear power plants in Hongyanhe, Ningde, Yangjiang, Fangchenggang, Haiyang, Xudapu, San'ao, Lufeng, Taipingling, Cangnan, Shidao, and Bailong. Its heat exchange technology subsidiary, leveraging expertise in fluid dynamics, innovatively developed passive air coolers for containment vessel shielding cooling water systems, supplying the world's first commercial fourth-generation high-temperature gas-cooled reactor.
Dunham-Bush, another subsidiary, is a global nuclear island chiller service provider with over 20 years of experience in the nuclear sector. It is the primary drafting unit for China’s National Energy Administration standard "Nuclear Air and Gas Treatment: Ventilation, Air Conditioning, and Air Purification—Part 18: Refrigeration Equipment." As the only domestic manufacturer with comprehensive nuclear island chiller applications across all zones, it boasts extensive domestic and international project experience. Recently, it secured a contract for cooling systems in floating small modular reactors (SMRs), aligning with China’s emerging distributed energy development in SMRs.
Additionally, Huayuan Taimeng, another subsidiary, built upon its absorption heat exchange technology—awarded China’s Second Prize for National Technological Invention—collaborated with Tsinghua University to develop simultaneous water-heat production and delivery (applied in nuclear-powered seawater desalination) and large-temperature-difference long-distance nuclear heating. These technologies have been implemented in State Power Investment Corporation’s "Warm Nuclear No. 1" heating project, which was featured by national media as "China’s First Cross-City Nuclear Heating Project Officially Launched."
