Introduction

Part Four addresses the role of people in the nuclear industry and provides a set of concrete studies and interventions which focus on human resource management, operator action, and human error.

A research study of the role of implicit safety-related norms in their impact on safety behavior is reported on by Ignatov. The study took place in an East European nuclear power plant, uses an innovative scenario methodology, and shows that, contrary to expectations, it is less safetyrelated attitudes that influence behavior than safety-related, implicit, often unconscious, norms. This finding has important implications for leadership and training in nuclear power plants.
