核动力设备耦合优化设计研究

核动力设备重量是评价核动力装置性能的标准之一。蒸汽发生器与稳压器是反应堆一回路中的重要设备，在保证实现其各自功能的前提下，降低这2个设备的重量能提高整个核动力装置的性能。本工作基于秦山核电厂相关设备资料，自主开发了对蒸汽发生器和稳压器进行重量优化设计的计算程序，采用粒子群 模拟退火方法开展多参数优化设计。结果表明，通过参数的重新组合优化，2个设备重量之和减少了18.61%，优化效果显著，相关结果可作为工程设计参考。

Study on Coupling-Optimization Design of Nuclear Power Plant

Weight is one of the criteria to evaluate nuclear power plant performance. Steam generator and pressurizer are important equipments in the primary loop. The plant can be improved through decreasing the weight of equipments if all requirements on the equipments are still fulfilled. Based on Qinshan nuclear power station parameters, the weight optimization codes for steam generator and pressurizer were developed. The particle swarm-simulated annealing method was used for multi-parameters weight optimization of two steam generators and one pressurizer in nuclear power plant. The results show that the total weight of the two equipments is reduced by 18.61%, and the optimization effect is obvious. The results can provide some insights for design of nuclear power plant.
