摘　　要：本文建立了泳池式低温供热堆堆芯最优临界棒位搜索方法模型,设计并编程实现了基于快速非支配排序的遗传算法。该算法以控制棒组棒位为输入,以临界偏离度、核热点因子、核焓升因子为目标函数,搜索出满足热工水力和安全限值的优化解集,为解决无硼控堆芯最优临界棒位搜索提供了新的途径。The model of optimal critical rod position search method was established in this paper,which was based on fast nondominated sorting genetic algorithm.The optimal critical rod position which meets the thermal-hydraulic and safety limit was gotten with the rod position as input,and critical deviation,nuclear hot factor and nuclear enthalpy rise factor as objective functions.A new way to search the optimal critical rod position is provided for boron-free core.
