Replies are rewarded – discussions are welcome.-------------------------------------------Recently, the China Nuclear Energy Industry Association held a meeting to assess scientific and technological achievements via video conference, during which the technical achievement of the \"seismic-resistant deluge valve assembly prototype\" jointly developed by First Safety and Huaneng Nuclear Energy Technology Research Institute was unanimously approved. Experts from organizations such as the China Nuclear Energy Industry Association, the China General Machinery Industry Association, the Nuclear and Radiation Safety Center of the Ministry of Ecology and Environment, the China Nuclear Power Research and Design Institute, CNNC Nuclear Power Engineering Co., Ltd., Shanghai Nuclear Engineering Research and Design Institute, Beijing University of Chemical Technology, CNNC Nuclear Power Operation Management Co., Ltd., and Fujian Fuqing Nuclear Power Co., Ltd. participated in the evaluation. Seismic-resistant deluge valve assemblies are key components of the fire protection systems in nuclear power plants. Shouan Company, in collaboration with Huaneng Nuclear Energy Technology Research Institute, has made innovative efforts to achieve domestic substitution for such technical products. Taking into account the special requirements of nuclear power facilities, seismic design studies were conducted on these products based on prior seismic analysis of existing deluge alarm valves, resulting in a significant improvement in their reliability. In addition, through independent research and development, Shouan has equipped the seismic wet-stopping alarm valve assemblies in nuclear power plant fire protection systems with smart fire protection capabilities. Its key components not only enable real-time monitoring and data feedback by traditional fire alarm controllers, fire control centers, and big data platforms such as fire protection IoT systems, but also establish an interactive response mechanism via mobile apps, thereby improving the overall level of intelligence in the management of fire protection facilities in nuclear power plants. This intelligent seismic deluge valve assembly is the first of its kind in China, and during its development, it succeeded in overcoming the challenge of localizing key equipment for the nuclear power sector. The successful implementation of this R&D project will play a significant role in enhancing the reliability of the safe operation of fire protection systems in the nuclear power sector, as well as the competitiveness of related product technologies, and it will also contribute to increasing the proportion of domestically produced equipment in the nuclear power industry.
