“…In CAHR, dozens of PSFs are classified into eight categories, including environment, situation, order issue‐dispatch, task, feedback, person, activity, and system (Sträeter, 2000). The human event repository analysis (HERA) database developed by NRC models its PSF set based on SPAR‐H (Gertman et al, 2004) and HRA good practices (Kolaczkowski, Forester, Lois, & Cooper, 2005), and finally includes all eight PSFs from SPAR‐H and three more PSFs (communication, environment, and team dynamics and characteristics) from HRA good practices (Hallbert et al, 2006). Recently, a new database called Scenario Authoring, Characterization, and Debriefing Application (SACADA) is under development by the NRC, which adopts a macrocognition model as its cognitive science foundation (Y. H. J. Chang et al, 2014).…”

The commissioning of a nuclear power plant (NPP) is the last stage in the life cycle of an NPP before commercial operation. Human errors in this stage cannot only harm workers' safety but can also cause damage to system facilities, postpone the commissioning schedule, and become latent problems in the system if the errors are not discovered during the commissioning stage. Therefore, identifying and controlling potential human errors is of great importance at this stage. This study first reviewed

Abstract-The goal of performance shaping factors (PSFs) is to provide measures to account for human performance. PSFs fall into two categories-direct and indirect measures of human performance. While some PSFs such as "time to complete a task" are directly measurable, other PSFs, such as "fitness for duty," can only be measured indirectly through other measures and PSFs, such as through fatigue measures. This paper explores the role of direct and indirect measures in human reliability analysis (HRA) and the implications that measurement theory has on analyses and applications using PSFs. The paper concludes with suggestions for maximizing the reliability and validity of PSFs.

“…NUREG-1792, Good Practices for Implementing Human Reliability Analysis (HRA) [5], emphasizes examining human performance throughout the entire accident sequence for commonalities, similarities, and links among the actions, such as when involving the same crew members, occurring closely in time, sharing a common mindset, etc. In other words, the Good Practices document advocates considering the context of the actions in question when assessing dependency.…”

“…The HERA approach to dependency is based in part on the Good Practices in HRA document [5], but it differs slightly from the standard processes used in individual HRA methods, as it was designed to be informative to HRA in general, regardless of the specific method being employed. As HERA was being developed, it became clear that the approach to dependency offered by the many HRA methods was not appropriate for the data used in HERA.…”

“…HERA provides discussion for determining when dependency should be assessed, information about a variety of factors that lead to dependency between human actions to aid analysts in determining the proper dependency level, discussion about temporal issues that affect dependency calculations, and guidance for properly considering diagnosis and action when assessing dependency. Armed with guidance from the HRA Good Practices [5], and guidance from HERA [7], HRA analysts will be better prepared to appropriately and accurately characterize and include dependency in their HEP calculations.…”

Abstract-Dependency occurs when the probability of success or failure on one action changes the probability of success or failure on a subsequent action. Dependency may serve as a modifier on the human error probabilities (HEPs) for successive actions in human reliability analysis (HRA) models. Discretion should be employed when determining whether or not a dependency calculation is warranted: dependency should not be assigned without strongly grounded reasons. Human reliability analysts may sometimes assign dependency in cases where it is unwarranted. This inappropriate assignment is attributed to a lack of clear guidance to encompass the range of scenarios human reliability analysts are addressing. Inappropriate assignment of dependency produces inappropriately elevated HEP values. Lessons learned about dependency usage in the Human Event Repository and Analysis (HERA) system may provide clarification and guidance for analysts using THERP-based dependency models. This paper presents the HERA approach to dependency assessment and discusses considerations for dependency usage in HRA, including the cognitive basis for dependency, direction for determining when dependency should be assessed, considerations for determining the dependency level, temporal issues to consider when assessing dependency, (e.g., considering task sequence versus overall event sequence, and dependency over long periods of time), and diagnosis and action influences on dependency.
