Huaneng Shandong Shidao Bay Nuclear Power Plant High Temperature Gas-cooled Reactor Demonstration Project adopts the fourth-generation nuclear power technology with completely independent intellectual property rights in China and was developed by Tsinghua University. It was listed in the “National Medium and Long-Term Scientific and Technological Development Plan Outline (2006-2020)â€. Inclusion in national major science and technology projects. Huaneng Shandong Shidaowan High Temperature Gas-cooled Reactor Demonstration Project is the world’s first 200,000-kilowatt high-temperature gas-cooled reactor commercial demonstration power plant using this technology. Its nuclear-grade and non-nuclear-grade digital instrumentation control systems are all provided by Guangli Nuclear.
Sun Yongbin, deputy general manager of Guangli Nuclear, said that the application of the first-generation commercial nuclear reactors for the first generation of nuclear power generation and the first set of equipment for the DCS of independent nuclear power levels means that the owner, the general contractor, the designer, and the Guangli nuclear power plant are all serious. test. From the development and identification of prototypes to the design, manufacture, and testing of actual supply equipment, the project team faces many difficulties and challenges, such as large engineering design, complex project implementation, and a wide range of design changes, etc., only with the special project of the designer Tsinghua University. The seminar was more than a hundred times more. Nearly 200 design documents have been developed for the development of equipment, with approximately 10,000 pages and software codes of nearly 110,000 lines. Many key technical solutions have been finalized after repeated discussions and revisions by dozens of parties, and for the first time will be “customized†and “customizedâ€. The introduction of the "modular" design implementation program throughout the life cycle of the project further enhances the reliability of the system.
In December 2014, Guangli Nuclear and Tsinghua University collaborated closely to develop a prototype 1:1 prototype of a nuclear DCS system in the Shidao Bay nuclear power plant demonstration project for high-temperature gas-cooled reactors based on the proprietary nuclear-level DCS “Harmony System†developed by Guangli Nuclear. . In March 2016, based on the prototype, Guangli Nuclear completed the design, production and assembly of the actual supply equipment. In December of the same year, all equipment passed the factory acceptance test (FAT). At present, Shidao Bay nuclear power plant high-temperature reactor demonstration project is progressing as planned, has entered the equipment installation and commissioning stage.
It is reported that the "Harmony System" is a nuclear-level digital instrumentation control system independently developed by China. Due to strict quality standards, large investment in R&D, and high requirements for identification, the nuclear-level digital instrumentation control system has only a handful of developed countries mastering this technology for a long time and has become one of the most difficult fortresses to be overcome in China's nuclear power research and development field. In October 2010, Guangli Nuclear successfully developed the “Harmony System†to fill the gap in China’s technology and broke the long-term monopoly of Western countries in this field. As a result, China became the second largest country in the United States, France, and Japan. Four countries that master the technology.
According to Sun Yongbin, in addition to the Huaneng Shandong Shidao Bay high-temperature gas-cooled reactor demonstration project, the “Hexi system†has been determined to be used in Hualong No. 1 demonstration power station Fangchenggang No. 3 and No. 4 units; Yangjiang nuclear power unit No. 5 and No. 6; Hongyanhe Nuclear power 5, 6 units; and Tianwan Nuclear Power Units 5 and 6 and 8 new kilowatt-class nuclear power generating units have achieved multi-technology and multi-pillar application coverage, saving nearly 3 billion yuan in nuclear power construction in China. . The application of the “Peace and Harmonic System†in China’s nuclear power plants has also strengthened the autonomous genes for the construction of many nuclear power demonstration projects in China. It has become a new business card for China’s nuclear power equipment manufacturing and is used for the application of third-generation and fourth-generation nuclear power technologies in China. Promotion provides strong industry support.

The Guangli nuclear-level DCS will be successfully delivered to the fourth-generation nuclear power plant
[China Instrument Network Instrument R&D] On February 14, Huaneng Shandong Shidao Bay Nuclear Power Station, which was supplied by Beijing Guangli Nuclear System Engineering Co., Ltd. ("Guangli Nuclear") under China General Nuclear Power Group ("CGN") The high-temperature gas-cooled reactor demonstration project nuclear grade digital instrumentation control system (referred to as nuclear DCS) equipment has been successfully delivered. This is the first time China's autonomous nuclear DCS has been applied to the fourth-generation commercial demonstration nuclear power unit, which has important demonstration significance.
