Riyue Heavy Industry has won the bid for the M6 vessel ductile iron casting project from Xi’an Nuclear Equipment Corporation, with a contract value of CNY 164.8 million. This marks a major breakthrough in our heavy-duty precision casting and nuclear power equipment manufacturing business, demonstrating our technical strength and market competitiveness in high-end nuclear-grade castings, and further consolidating our leading position in advanced equipment manufacturing.

As a core subsidiary of China National Nuclear Corporation, Xi’an Nuclear Equipment is a premier provider of large-scale equipment design, manufacturing, integrated supply and full-lifecycle maintenance services. It focuses on four core businesses: nuclear environmental protection & fuel equipment, nuclear power facilities, special engineering equipment, and fire safety systems. It is currently China’s only manufacturer with proven capabilities for the complete Radioactive Fuel Handling & Storage System (RFH). The company enforces stringent standards for suppliers in technology, production processes and quality management.

Leveraging our mature heavy-section ductile iron technology, comprehensive nuclear-grade quality control systems, and large-scale casting manufacturing expertise, Riyue stood out in rigorous bidding and secured the contract.

In recent years, Riyue has focused on heavy-duty precision casting, driven by independent R&D and high-end market expansion. While strengthening our leadership in wind power castings, we have actively expanded into nuclear power and other strategic clean energy equipment sectors. With proprietary core technology for heavy-section ductile iron, we have overcome technical bottlenecks in manufacturing hundred-tonne vessel castings, and now deliver full-capability nuclear-grade product development, precision production and on-time delivery.

Fu Mingkang, President of Riyue Heavy Industry, commented:“We are honored to support Xi’an Nuclear in high-end nuclear equipment manufacturing. This deepens our strategic partnership established in June 2025 and represents a milestone in our nuclear-grade casting development. This achievement relies on our R&D team’s dedication to independent core technologies and strict plant-wide adherence to nuclear quality standards. Moving forward, we will continue to drive innovation and high-end upgrading, prioritize reliable delivery, strengthen R&D in new nuclear materials and processes, expand our nuclear equipment product portfolio, support domestic independence of critical nuclear components, empower new industrialization, and promote high-quality development in clean energy.”Building on this breakthrough, Riyue will further focus on high-end nuclear casting business, translate technical advantages into stable delivery capacity, advance nuclear-grade R&D and mass production, and expand strategic cooperation in nuclear equipment. We uphold craftsmanship in quality and innovation in breakthroughs, advancing domestic manufacturing of nuclear power equipment and delivering reliable hardware support for a clean, low-carbon, safe and efficient modern energy system.
