The Human Performance Event Database (HPED)

Summary for only given as follows. The purpose of this paper is to describe several aspects of a Human Performance Event Database (HPED) that is under development by the Nuclear Regulatory Commission. These include the background, the database structure and rationale, results from preliminary analyses, and the plans for the future. In 1992, the Office for Analysis and Evaluation of Operational Data within the NRC decided to develop a database for information on human performance during operating events. The database was needed to help classify and categorize the information to help feedback operating experience information to licensees and others. An NRC interoffice working group was established to develop the structure which is based on the Human Performance Investigation Process (HPIP) that had been developed by the NRC as an aid in investigating events. The HPED currently includes data on events described in augmented inspection team (AIT) reports from 1990 through 1996, 20 AEOD human performance studies that were performed from 1990 through 1993, and recent NRR special team inspections. The database also includes data from the licensee event reports that were prepared for these events. The presentation includes discussions of the database structure and the basis for the structure, the process for coding and entering event data records, and the results of preliminary analyses of information in the database
