Summary
As the third generation of nuclear power technology booming in the United States and China,[1,2] such as AP10003,4 and CAP1400,5 reliabilities and motion performances of related electromechanical equipment should be improved.[6,7] At present, CAP1400 is one of the maximum nuclear power technologies under the research and development,[8,9] and only the construction cost of a CAP1400 nuclear power plant can be more than billions of dollars. The driving system was pneumatic, which still suffered from leakage problems and had a bad antiseismic performance.[14] At present, hydraulic–pneumaticpowered driving systems, which adopt hydraulic circuits to close the valves and nitrogen energy storing devices, are applied in nuclear power plants. This type of driving systems is much more reliable than the previous systems, and the working mode can be diversified, such as opening valves, keeping valves open, quick closing, and keeping valves closed, which can be examined locally.[15] the hydraulic–pneumatic-powered driving systems being on active service in nuclear power plants in the world, which are too complicated to be monitored and maintained, contain too many circuits and hundreds of components. One software platform is usually unable to fulfill the simulation tasks, so the co-simulation method is a better choice
