Hybrid Low-Order Harmonics and Linear Perturbation Expansion Method for Fast Loading Pattern Evaluation-Ⅱ:Numerical Verification

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.
