摘要
在反应堆物理设计中 ,为了展平堆芯功率、提高核燃料利用率和降低运行成本 ,必须对堆芯燃料管理作优化设计。该文着重介绍了模拟退火算法 ,针对优化堆芯物理设计提出了优化目标函数和罚函数 ,采用罚函数处理的方法进行模拟退火算法 ,对 NHR- 2 0 0反应堆作了实例计算 ,使首炉循环末的有效增殖因子 Keff提高了 2 .5 % ,展平了功率分布 。
A nuclear reactor must be optimized for incore fuel management to make full use of the fuel, to reduce the operation cost and to flatten the power distribution reasonably. This paper presents a simulated annealing algorithm. The optimized objective function and the punishment function were provided for optimizing the reactor physics design. The punishment function was used to practice the simulated annealing algorithm. The practical design of the NHR200 was calculated. The results show that the K eff can be increased by 2.5% and the power distribution can be flattened.
