摘要: 针对核电厂实际的堆芯装载方案优化问题,提出了一种新的优化算法——区间限界算法。介绍了该算法提出的背景,并描述了具体的实现过程。基于该优化算法,用Fortran95语言开发了相应的堆芯装载方案优化(LPO)并行计算程序IBALPO,并在一个比较难优化的实际换料问题上进行了测试。结果表明,IBALPO搜索出的方案优于经验丰富的工程师优化的方案。

Abstract: To solve the reactor loading pattern optimization problem in realistic nuclear power plants,this paper presents a new optimization method-Interval Bound Algorithm,and introduces the origin of the algorithm and describes its implementation procedure.Based on this algorithm,the corresponding parallel loading pattern optimization code of IBALPO is developed using Fortran95.Finally,this code system is used to solve a realistic and difficult reload problem to show its performance,and a better pattern is obtained compared to the one searched by experienced engineers.
