The Westinghouse Savannah River Company (WSRC), a contractor to the Department of Energy, has compared Revisions 1 and 2 of NUREG -0700-Human System Interface Design Review Guideline, from the United States Nuclear Regulatory Commission Nuclear Regulatory Guide. The comparison has been made between the two different revisions of NUREG-0700; specifically with respect to which guidelines remained the same, the guidelines that were reformatted or reworded, additional guidelines, and deleted guidelines. This comparison was made in preparation of revising the previously developed Human Factors Engineering Analysis Tool (HFE-AT) for automating the review, analysis, and evaluation of human system interface designs. This tool has been described at a previous IEEE Conference on Human Factors and Power Plants and the merits and benefits of the tool described at the 13th Annual Joint ISA/POWED/EPRI Controls and Instrumentation Conference. The tool has been successfully applied by WSRC to over eight facilities at the Savannah River Site (SRS).. This paper describes the methodology and results of the comparison and the plans to enhance the already successful automation tool. The number of criteria in NUREG-0700 increased from approximately 1650 in Revision 1 to almost 2200 in Revision 2. Approximately 1600 criteria remained the same, though they were significantly reorganized; while about 100 were reworded or reformatted to clarify or expand the guidance provided. Around 600 guidelines were added and approximately 70 deleted. The majority of the changes and additions reflect the recent impact that computer technology has had on industrial process control system human system interfaces and control rooms.
