In March 2026, the National Nuclear Safety Administration (NNSA) completed an information update on licensed civilian nuclear safety equipment units. Leading enterprises including Sufa Technology Innovation Co., Ltd. (SUFA) and Neway Valve Co., Ltd. successfully renewed their Class 1, 2, and 3 nuclear safety valve design and manufacturing qualifications, providing a fundamental safeguard for the stability of the nuclear power equipment supply chain. Based on public information, Akameng summarizes the key points of this list update.
Industry Signals Behind the Qualification Renewal
This qualification update comes at a critical stage, with the "Hualong One" reactor entering volume deployment and fourth-generation nuclear power demonstration projects accelerating. The renewed certificates—valid until the end of March 2026 and beyond—confirm that leading enterprises have consistently met the most stringent regulatory standards in the nuclear safety field in terms of quality control, technical R&D, and project delivery.
Neway's qualifications cover nuclear island core products such as globe valves, check valves, and ball valves, while SUFA, backed by the CNNC group, maintains a leading position in nuclear Class 1 valves and is a core force in the localization of key nuclear power valves. Given the high entry barriers for nuclear safety-grade valves and the long-term dominance of leading suppliers, this list confirmation both stabilizes supply chain expectations for nuclear projects under construction—such as Zhangzhou and Taipingling—and sends a clear signal of national support for independent control of nuclear power equipment.
Overview of Licensed Units
According to the NNSA's published list, licensed units cover multiple links in the nuclear power equipment chain, including design and manufacturing, engineering construction, and pump and valve supply. They include dozens of enterprises such as Dalian Shenlan Pump Industry, Dongfang Electric, China First Heavy Industries, Shanghai Electric KSB Nuclear Pumps & Valves, Zhejiang Sanfang Control Valve, Dalian Dahgao Valve, Shanghai Lianggong Valve Factory, and Harbin Electric Corporation's Harbin Power Station Valve. The complete list of licensed civilian nuclear safety equipment units is subject to the NNSA's official publication.
As nuclear power construction accelerates in China, licensed enterprises and their authorized channels will see new development opportunities. SUFA distributor Akameng, supported by factory qualifications and technical backing, can provide industrial customers with compliant non-nuclear-grade valve products and supporting services.
