Description

technical field [0001] The invention relates to a simulation technology of a nuclear power secondary loop system. Background technique [0002] With the widespread application of training simulators in nuclear power plants, it has been noticed that it is very promising and valuable to develop simulation software for engineering analysis and safety analysis. In the 1970s, several large-scale transient analysis programs such as TRAC, RELAPS, and RETRAN appeared in the United States for reviewing nuclear power production licenses. These simulation modeling software are based on basic mathematical equations, and the calculation methods are highly specialized. For nuclear power plants, based on the same completed design, dozens of nuclear power plants are often built, and the main systems in each nuclear power plant are highly similar, and the equipment has the same category and similar parameter design. For the preliminary design and demonstration stage of the nuclear power sec...

Problems solved by technology

The existing simulation modeling method is to establish a simulation model based on complete and definite design parameters. The simulation model cannot be modified at any time and applied at any time. The generality and adaptability of the simulation model are poor, and the modeling cycle is long.
