Abstract:
Small Modular Molten Salt Reactors (SM-MSRs) integrate modular design and molten salt reactor technology, with huge potential for future energy supply. Most current studies concentrate on analyzing and optimizing core physical features including core physics, fuel cycle and thermal-hydraulics, yet studies on system modular decomposition are still inadequate. This paper proposes a module partition approach for SM-MSRs based on the requirement-function-structure mapping matrix. First, requirement and physical structure models are built, and functional and structural Design Structure Matrixes (DSMs) are constructed individually. Then an integrated DSM is formed via weighted fusion, and an improved Louvain algorithm is employed for clustering to maximize modularity. By tuning the weights of functional and structural DSMs, the optimal partition scheme is acquired and weight configuration impacts are examined. Finally, the method is validated against the Molten Salt Reactor Experiment. The results offer theoretical support and methodological guidance for SM-MSR engineering modular design.
