Human Factors Review Guidance for Nuclear Power Plant Modification

Human factors should be systematically considered and integrated throughout the entire process of retrofit activities for nuclear power plants (NPPs). Considering characteristics of the retrofit project, this study at the China Ningde NPPs developed a human factors engineering (HFE) plan suitable for the retrofit project, established a HFE management framework for NPP retrofit activities, and developed supporting work plans and management procedures to manage and control the retrofit process. This ensures that the human-machine interface after retrofitting conforms to ergonomic principles, thereby minimizing the risk of human errors, optimizing personnel efficiency, and ensuring NPP safe and efficient operating.
