- The OECD Halden Reactor Project has for many years performed research on the safety of nuclear power plants (NPPs). The focus has been on empirical research in our simulator laboratory HAMMLAB (HAlden Man-Machine LABoratory) as well as on empirical studies in the field and in training simulators in NPPs. The MTO (Man-Technology-Organisation) perspective is a system-oriented perspective in which we seek to understand the dynamic relation between humans, technology and organization. The importance of MTO in control room design is evident by the fact that Human Factors Engineering (HFE) is included as a specific element in regulatory guidance in all countries that operate NPPs. This paper focuses on the need for empirical evidence to support MTO research; experience shows that empirical evidence can often contradict a-priori assumptions. Empirical investigations can help to: 1) identify key questions that control room designers and regulatory reviewers should ask; 2) define ideas for new and innovative designs; 3) evaluate and validate human performance in the control room, with respect to both integrated system validation (ISV) as well as human reliability. This paper outlines examples of results from empirical research carried out by the Halden Reactor Project to address these different needs in the nuclear industry.
