The 719th Research Institute of China Shipbuilding Industry Corporation (hereinafter referred to as the "719th Institute") is affiliated to China Shipbuilding Industry Corporation. It was established in 1965 and is the only unit in my country that has the qualifications and performance for the overall design of nuclear-powered ships. With more than 50 years of engineering experience in the overall design, operation and maintenance support, and decommissioning of marine nuclear power plants, it is a multidisciplinary and multi-professional national key scientific research institute integrating overall research, design, and civil industrialization. The 719th Institute is also the leading unit of the National Energy Marine Nuclear Power Platform Technology R&D Center. It has the National Civilian Nuclear Safety Mechanical Equipment Design License, the Civilian Nuclear Safety Electrical Equipment Design and Manufacturing License, and the Class A Ship Design License. It is currently It is the only unit capable of overall design of marine nuclear power platforms and is also the general contractor of marine nuclear power platform demonstration projects.

719 Institute has grown into a competitive nuclear power engineering design service provider, nuclear power engineering complete set supplier, and nuclear power operating power plant technical service provider. Its products and services have covered all domestic commercial nuclear power plants. In terms of nuclear power engineering design, the 719th Institute has the overall design and development capabilities for military-civilian integrated marine nuclear power devices, as well as the design capabilities for all mechanical equipment of nuclear power plants except reactors, evaporators, and various pumps, and the layout design of nuclear power plants and auxiliary plants. ability. Independently develop my country's first marine nuclear power platform, break through the localization of key equipment, and continue to approach the breakthrough goal of "zero" my country's marine nuclear power platform. Relying on the marine nuclear power platform demonstration project, we will deeply explore the marine nuclear energy application market, and based on domestic demand, carry out the research and development of new nuclear-powered ships such as nuclear-powered icebreakers, nuclear-powered heating ships, and nuclear-powered comprehensive support ships. Completed the construction of the nuclear power plant system three-dimensional design (PDMS) platform to meet the design needs of second-generation plus and third-generation nuclear power technology, completed Fangcheng layout design and other design work, and the design quality has been commended by the owner many times.

In terms of nuclear power engineering complete sets and system integration, the product range has been broadened to cover radiation protection and monitoring, decontamination, sampling, three wastes and other systems. It has successfully replaced the French MGP company and has become the only unit in China that can provide a complete set of domestically produced KRT systems. It is one of the two units with domestic KRT system design and manufacturing licenses. Signed a cooperation agreement on localization research and development of "Hualong One" nuclear-grade instrumentation and control equipment with China General Nuclear Power Corporation, becoming the sole partner of the KRT system for the first overseas project. It has independently developed various types of equipment such as nuclear decontamination, nuclear sampling, waste treatment, and emergency generator sets, all of which have filled domestic gaps. It has won 28 patents and 3 China Shipbuilding Industry Corporation Science and Technology Progress Awards.

719 Institute has the capability to design and manufacture nuclear-grade high-end valves, third-generation nuclear power modular equipment, and develop third-generation nuclear power instrumentation and control equipment. The first company in China to complete the development of the AP1000 blasting valve principle prototype, and won a 120 million yuan supply contract for the blasting valves of Lufeng Nuclear Power Unit 1/2. It has developed a series of products such as main steam isolation ball valve, high temperature and high pressure bellows stop valve, and high pressure flat gate valve, and is initially capable of large-scale production. The independently developed AP1000 modular equipment: MS20 primary loop sampling module, MS08 desalted water deaeration module and condensate deaeration module are the first sets of similar equipment in the world and have been successfully delivered to Sanmen and Haiyang nuclear power plants.

Based on design and technical services, 719 focuses on system integration and high-end equipment manufacturing, fully realizes the localization of third-generation nuclear power in its advantageous areas, actively expands the development of the marine nuclear energy industry, and strives to become a first-class domestic nuclear power equipment system integration supplier.
