The autonomy of nuclear power software is an important link in the autonomy of nuclear power and an important indicator of the level of nuclear power technology in a country. At present, the United States, France, Russia and other nuclear power countries have a full set of nuclear power software, and China's nuclear power software has long relied on imports, seriously restricting the autonomy of nuclear power technology.
The national electric power investment relies on the national large-scale advanced pressurized water reactor major project, the United Nations nuclear power industry more than 10 dominant scientific research units, the formation of a national nuclear power software R & D team, in strict accordance with international nuclear safety standards to carry out nuclear power key design software independent research and development work, achieved Significant achievements: First, independently developed China's first nuclear power plant nuclear engineering design and safety analysis software package COSINE with complete independent intellectual property rights, including 8 major categories and 15 thermal engineering design, safety analysis and core physical design. The software covers more than 80 functions of international similar software, and has all the core functions of nuclear power plant nuclear engineering design and safety analysis. Second, it promotes the establishment of nuclear safety guidelines and development standards for nuclear power software development and application in China, and guides China's nuclear power. The development and application of software; Third, the establishment of China's first relatively complete nuclear power software evaluation database, laid the foundation for nuclear power software verification and evaluation.
The COSINE software package has been granted 5 invention patents and 29 software copyrights. The expert group of “Nuclear Power Key Design Software Autonomous Technology Research†believes that the overall technical indicators and performance of the achievement have reached the international advanced level, and some key technologies have reached the international leading level. It is the first important milestone in the history of nuclear power software development in China.
In December 2015, the public beta version of the COSINE software package was officially released and has been tested and applied for the design review of the CAP1400 demonstration project. Later, in accordance with the relevant laws and regulations of China, it will be officially used for nuclear power after obtaining the license of the national nuclear safety regulatory authority. The engineering design of the plant. This achievement will help to improve the "soft power" of nuclear power in China and promote the independent development of nuclear power technology. It is of great significance for us to build a nuclear power powerhouse and accelerate the "going out" pace of nuclear power enterprises and nuclear power technology.
