ABSTRACT
Effective nuclear power plant operation is a complex process that requires reactor operators to work together as a crew and follow prescribed procedures to ensure continuous, safe operations. These operations crews undergo extensive training to ensure consistent peak performance. Unfortunately, even highly trained crews who perform, on average, very effectively, may vary in their performance. Although performance inconsistencies may be inconsequential for some work groups, inconsistency can produce serious consequences in nuclear plant operations. What factors influence crew performance variability, and how can these factors be influenced by organizational actions so as to reduce such variability?
