Background: The Monte Carlo (MC) method is widely used in fission reactor design, because of its stronger geometry adaptability and the precise calculation result. The high-fidelity full core simulation demands for detailed fission reactor models, which is hard to build by manual and the conventional Computer Aided Design (CAD)-based modeling method. Purpose: In order to support the rapid design of fission reactor core with MC method, and generate the detailed MC calculation models, a parameter-based and visual MC modeling method was developed in this study. Method: The method can create the detailed CAD models and convert them into MC models in a high-efficiency way. Meanwhile, the huge amounts of models in fission reactor core can be managed by different segments for supporting smooth interactions. Result: Furthermore, the method was validated by the test of creating the Accelerator Driven Sub-critical System (ADS) reactor models, and the results were agree very well by comparing the reference models. Conclusion: Depending on the test, the detailed fission models were created more conveniently than conventional method and the numerical calculation results proved the accuracy of the new method.
