AP1000 is the third-generation nuclear power technology introduced from Westinghouse in China. The CAP nuclear power is the third-generation nuclear power technology that is based on the digestion and absorption of AP1000 nuclear power technology and has independent intellectual property rights. As ASME code class I component

in order to ensure the smooth development at site and meet the installation quality of the main pipe

a physical simulation of 1:1 ration is conducted before the formal installation

which is to simulate the process of machining

fitting

and welding about single loop main pipe. Through the 3D modeling technology

the construction process is monitored in real-time

the control measures

crafts and results meeting design requirements is verified

so as to accumulate experience for the formal construction of the main pipeline.
