Abstract

The performance shaping factors (PSFs) of the standardized plant analysis of risk-human reliability analysis (SPAR-H) method are unclearly defined, which contributes to the uncertainty of human reliability analysis (HRA) in nuclear power plants (NPPs). This work proposes an expert-based modification approach for redefining the PSFs based on four criteria in terms of less overlap, hierarchy, flexibility, and digitalization. For demonstration, the proposed approach is used to assign PSFs to three specific human failure events in NPPs. Three tests (Kendall's W Test, Jonckheere-Terpstra Test, and Paired Samples Test) are applied to analyze the assignments. Compared to the PSF assignment of SPAR-H, the results show that the redefined PSFs meet the four criteria and reduce the overestimation of human error probabilities (HEPs).
