Cognitive Environment Simulation as a Tool for Modeling Human Performance and Reliability. Main Report.

摘要

The U.S. Nuclear Regulatory Commission is sponsoring a program to develop improved methods to model cognitive behavior of nuclear power plant (NPP) personnel. A tool called Cognitive Environment Simulation (CES) was developed for simulating how people form intentions to act in NPP emergencies. CES provides an analytic tool for exploring plausible human responses in emergency situations. In addition a methodology called Cognitive Reliability Assessment Technique (CREATE) was developed that describes how CES can be used to provide input to Human Reliability Analyses (HRA) in probabilistic risk assessment (PRA) studies. The report describes the results of three activities that were performed to evaluate CES/CREATE. The results of all three evaluations indicate that CES/CREATE is a promising approach for modeling intention formation. Volume 2 provides details on the three evaluations, including the CES computer outputs for the tube rupture events.
