With the increasing complexity of nuclear reactor design, in order to improve the efficiency and economy of the design and development of complex systems and form a complete digital prototype development system, model-based systems engineering (MBSE) is applied to system design and development. So as to further meet the convenient management of MBSE complex relationship requirements, this paper first analyzes the SysML (systems modeling language) requirements relationship, and builds a requirements management interaction platform based on this, so that it fully conforms to the SysML requirements relationship. Secondly, based on the underlying principle of SysML language, the two-way data binding between the requirements management interactive platform and the modeling software CSM (cameo systems modeler) is realized. Finally, the feasibility of the method is verified by the requirements of the nuclear reactor, and the management of the unified model data and automatic conversion of text to model is realized.
