The key PSF in intelligent nuclear power plant main control room: From the perspective of trust and reliance

Abstract

HRA represents the latest understanding of human performance in the socio-technical system and should be integrated iteratively with the system implementation process. Some Fields have already initiated intelligent transformation, and the nuclear power field also will be entering that. However, fully unmanned systems are still impossible, human reliability will continue to be crucial in intelligent systems. PSFs play a significant role in HRA, including risk prevention, risk quantification and risk traceability. Given this consideration, this study conducted a predictive exploration of PSFs for intelligent NPP MCR. We emphasized the necessity of incorporating trust and reliance into the HRA process and identified factors that affect them based on an impact framework, considering these factors as key PSFs. The findings of this study can inform risk prevention strategies for intelligent NPP MCR and provide guidance for risk traceability efforts.
