Task Analysis as a Cornerstone Technique for Human Reliability Analysis

摘要

Qualitative analysis is essential for obtaining credible and useful HRA results, yet most HRA method descriptions fail to adequately describe how to perform qualitative analysis. Research by the Halden Reactor Project identified task analysis as one of the key qualitative techniques for HRA, and also one of the most challenging for less experienced analysts. This paper makes an argument for why task analysis should be considered a cornerstone technique for qualitative HRA, and also describes current Halden research activities to investigate the role of task analysis in HRA, and to develop support tools for analysts to address these challenges.
