TASK NETWORK MODELING OF HUMAN OPERATIONS IN NUCLEAR POWER PLANT CONTROL ROOMS

THE PURPOSE OF THIS EFFORT IS TO STUDY THE FEASIBILITY OF AND, HOPEFULLY, VALIDATE THE USE OF TASK NETWORK MODELING TOSTUDY HUMAN FACTORS IN THE CONTROL ROOM. TASK NETWORK MODELING EXTENDS A HUMAN ENGINEERING TASK ANALYSIS INTO A COMPUTER MODEL. WE PROPOSE THAT PERTURBING THE INDIVIDUAL TASKS IN A TASK NETWORK MODEL IN A MANNER PREDICTED FROM CONTROL ROOM DESIGN CHANGES, TASK AUTOMATION, OR THE CONSIDERATION OF HUMAN PERFORMANCE STRESSORS, THE HUMAN ENGINEERS OVER THE PAST DECADE. HOWEVER ITS EFFICACY HAS NEVER BEEN PROVEN IN THE NUCLEAR OPERATIONS ENVIRONMENT. THIS STUDY WILL SEEK TO DETERMINE THE PRACTICALITY AS WELL AS VALIDITY AT TASK NETWORK MODELING AS A TOOL FOR THE ANALYSIS OF HUMAN FACTORS IN NUCLEAR SYSTEMS.
