Abstract

The Idaho National Laboratory (INL), sponsored by the Nuclear Regulatory Commission, has developed a repository entitled Human Event Repository and Analysis (HERA). The objective of HERA is to make available empirical and experimental human performance data, from commercial nuclear power plants (NPPs) and other related technologies, in a content and format suitable to human reliability analysis (HRA) and human factors practitioners. This Volume 1 of NUREG/CR-6903, discusses the need for a systematic collection of human performance data on the basis of current regulatory HRA and human factors applications, describes the taxonomy and structure of the data in HERA, and presents examples of information extraction and coding.
