摘要

将离散微分进化算法（DE）应用于Apsara-U研究堆堆芯负荷优化。目标是通过将燃料组件的最大功率限制在173千瓦来最大化堆芯的过度反应性。首先，计算验证了文献中给出的突变尺度因子和交叉率的最优值。随后，在种群规模为10的情况下，进行了500代的DE搜索。发现反应性在350代后达到最大值。结果表明，对于给定的核心配置，与实现的模式相比，可以获得提供更高反应性增益的加载模式。

Core loading optimization of Apsara-U research reactor using differential evolution algorithm

A discrete differential evolution algorithm (DE) has been applied for optimizing core loading of Apsara-U research reactor. The objective is to maximize the core excess reactivity by restricting the maximum power of a fuel assembly to 173 kW. First, calculations were performed to verify the optimum values of mutation scale factor and crossover rate given in the literature. Subsequently, DE search was performed up to 500 generations with the population size of 10. It is found that the reactivity reaches its maximum value after 350 generations. The results show that, for a given core configuration, it is possible to obtain loading patterns which provide higher reactivity gain compared to the implemented pattern.
