This report describes a human factors research project performed to: (1) support the Severe Accident Sequence Analysis (SASA) program and (2) develop a descriptive model of operator response in accident management. The first goal was accomplished by working with SASA analysts on the Browns Ferry Unit One anticipated transient without scram (ATWS) accident sequence to systematically assess critical operator actions and thereby demonstrate contributions to SASA analyses from human factors data and methods. The second goal was accomplished by developing a model called the Function Oriented Accident Management (FOAM) model, which provides both a conceptual structure linking off-normal safety functions with potential unconventional emergency responses and a method for developing technical guidance for those responses based on operations, engineering, and human factors data and expertise. The four components comprising the model are described and their use is shown through a table-top demonstration. 48 refs., 30 figs., 9 tabs.
