摘要: 通过设计组件两两交换、组件全排列、燃料棒功率和燃耗计算等系列检验算例,对谐波结合线性扰动展开法(HHLP)进行了数值检验。结果表明,HHLP方法用于换料方案评价,不仅具有极快的速度,还具有很高的精度和适应性;同时,由于HHLP方法具备燃耗计算和燃料棒功率分布的计算能力,使得该方法具有很强的工程应用潜力。

Abstract: In order to address [U2] the issue of large computational workload in the process of optimum loading pattern search for commercial PWR NPP, a new method--Hybrid Harmonics and Linear Perturbation （HHLP） is proposed to perform the fast loading pattern evaluation. While another accompanying paper introduces the theory of HHLP method, this paper summarizes the extensive test results for various test problems, including a depletion problem, large and extremely large perturbation problems and two exhaustive enumeration problems and enumerated LPs. Numerical results demonstrate that all these results are consistently good and HHLP method is very promising.
