MBSE-based nuclear fuel closed cycle economic evaluation modeling method

The invention belongs to the technical field of system engineering and nuclear fuel circulation, and particularly relates to a nuclear fuel closed circulation economic evaluation modeling method based on MBSE. The method comprises the following steps: step 1, carrying out structural modeling on specific links and logical relationships of a nuclear fuel closed cycle technical route by adopting an SysML language; 2, behavior modeling is carried out according to the structure diagram and the interaction behavior diagram obtained in the step 1, and the starting sequence of all modules is determined; and step 3, performing parameter modeling on the basis of the structural diagram and the interactive behavior diagram established in the step 1 and the execution process modeling established in the step 2, and realizing the functions of calculating the amount of matter and calculating the power generation cost per kilowatt-hour. By adopting the MBSE method and tool, the complex influence relationship between different
