Abstract: In order to solve the chronic leakage problem at the tubing interface, a shape memory alloy (SMA) used for naval nuclear reactor coupling was studied. A structural optimal model for the NiTiNb shape memory alloy coupling was established. Using the genetic algorithm, the structural design of the NiTiNb pipe coupling was optimized. The NiTiNb shape memory alloy coupling was then analyzed through the thermalstructural coupled simulation using the finite element method. The results suggest that the computational results agree well with the theoretical data. Therefore, the method proposed is feasible and effective, and has great versatility and practical significance.
