Multi-objective Optimization Design on Nuclear Power Primary Circuit System

The primary circuit system mathematical model evaluating procedures were compiled, and the effects of thermal and structure parameters on the primary circuit system weight and volume were discussed. The multi-objective optimization of the primary circuit system weight and volume was carried out based on the self-developed hybrid particle swarm optimization. The calculation results show that the total weight and total volume of primary circuit system were reduced by 12.75% and 13.69% respectively after using the optimization strategy, and the optimization effect is obvious.
