Cognitive processes and PEMS of TSA in digitized MCRs of NPPs

Abstract

In order to identified macro-cognitive processes and psychological error mechanisms (PEMs) of TSA in digital NPPs. Firstly, the components of TSA are identified according to team task analysis, which including individual situation awareness (ISA), shared situation awareness (SSA) and mutual awareness (MA). Furthermore, the macro-cognitive processes of TSA are identified respectively from ISA, SSA and MA on the basis of simulation experiments, and the process model of TSA is established to illustrate the forming mechanism of TSA. Finally, the PEMs of TSA errors are identified, it is very useful to prevent and reduce TSA errors.
