Development of nuclear power simulation technologies

The status and characters on the development of nuclear power simulation technology were reviewed. The advance of nuclear power system simulator was analyzed emphatically. The new trend of nuclear power simulation technology advance was explored. According to the analysis results, it is pointed out that the advancing tendency of nuclear power simulation technology is modularization, integration, digital, virtual, network and intelligence simulation. Based on 3-D simulation design, the nuclear power simulation technologies are expanded in the direction of the design and manufacture of nuclear power system, and the design of digital nuclear power plant (NPP), which takes the whole life cycle management of NPP as the design goal, is an important field of the nuclear power simulation technology research and application.
