Abstract
Progress to data on assessing the nature of the expected changes in human performance and risk associated with the introduction of digital control, instrumentation and display systems is presented. Expected changes include the shift toward more supervisory tasks, development of intervention strategies, and reallocation of function between human and machine. Results are reported in terms of the scope of new technology, human performance issues, the experience of the crew with digital control systems in a variety of industries including petrochemical and aerospace. Plans to conduct a limited probabilistic risk assessment/human reliability assessment (PRA/HRA) comparison between a conventional NUREG-1150 series plant and that same plant retrofit with distributed control and advanced instrumentation and display are presented. Changes needed to supplement existing HRA modeling methods and quantification techniques are discussed.<>
