摘　　要：研究遗传算法在HFETR堆芯优化设计中的应用。计算程序中部分参数采用岷江试验堆堆芯优化程序中已采用的参数,计算方法上引入了对称变异算子与虚拟堆芯技术。虚拟堆芯技术的引入减少了获得优化方案的计算时间,而对称变异算子的应用增加了优化方案的工程实用性。从优化结果可以看出,转换比与同位素总产量都可提高10%以上,优化堆芯装载方案对称实用,满足工程要求。Application of GA in HFETR core optimization design had been discussed. A part of parameters used in program had been taken from the code used in MJTR core LP optimization program. In the same time, two new techniques, imaginary core technique and symmetric mutation operator, had been introduced. ICT had been used to reduce the calculation time of optimization, while SMO had been used to increase the engineering applicability of the core design. The optimization result shows that the conversion ratio and radioisotope output have been increased more than 10%, and the optimal LP is symmetric and practical, and satisfies the engineering requirement.
