中文摘要：

介绍了遗传算法与禁忌搜索算法相结合的混合优化算法在六角形组件压水堆堆芯布料方案优化计算中的应用．采用该混合优化算法分别以寿期末硼浓度最大、功率峰因子最小和兼顾寿期与功率峰因子为目标对Kalinin—5核电站第二循环布料方案进行了优化计算．结果表明，混合优化程序所得到的最优堆芯布置明显优于原堆芯布置．

英文摘要：

The hexagonal PWR core reloading optimization code system was presented, which applies a new hybrid optimization method （combining the genetic algorithm with the tabu search）. The verification and validation of 2-D code system were examined by the calculation of IAEA WWER-1000 type PWR reactor Kalinin-5 NPP problem. The reloading optimization package was used to optimize the cycle length, the power factor and the synthesis of the two facets respectively. The numerical results show that the new reloading optimization code system is effective and successful.
