With the improvement of digital level of main control rooms (MCRs) of nuclear power plants (NPPs), the issue of situation awareness (SA) of operator becomes particularly prominent in NPP operations. More and more scholars have done some research on SA and team situation awareness (TSA). In order to explore the effects of performance shaping factors (PSFs) on SA, TSA and workload, the effects of task complexity and operators’ knowledge and experience level on operators’ SA, TSA and workload were studied through simulator experiments. The resul...
