Abstract

Main control room (MCR) is an important site of the nuclear power plant (NPP), and the environmental condition in MCR shall be benefit to operators performing their task effectively and comfortably. With the development of HFE (human factor engineering), there is more attention to environment design of MCR. the MCR environment design mainly include noise reduction, illumination, air condition, interior and colour design, earthquake protection, fire protection, radiation protection, missile protection, and so on. At present, the indexes for environment design of domestic and international regulations and standards are inconsistent. None of regulations and standards is comprehensive, detailed and fully adapting to the MCR environment design of NPP, and some indexes are difficult to achieve. This paper compares the indexes of MCR environment of regulations and standards, performs HFE study about the indexes of MCR environment design combining with engineering experience in different NPPs. Finally, this paper proposes a set of environment design indexes applied to MCR of NPP, which will guide the MCR environment design of third generation NPPs.
