Chet Poslusny SUBJECT PROPOSED SCOPE OF OPERATillG EXPERIEllCE REVIEW FOR ABWR HUMAli FACTORS ENGillEERil1G DESIGil FOR ABWR Enclosed for your use is a proposed scoae of an operating experience review which is related to the resolution of tie open item include in the DFSER.
This is provided as a followup to the phonecall held with the staff last t
month. We expect that a call will be required to discuss what actions GE plans to take to close out this item. As per GE's issue Resolution Schedule, this item should be completely resolved by the end of January.

OERATING EXPERIENCE REVIEW fladdLragn:
The accident at Three Mile Island (TMI) in 1979 and other reactor incidents illustrated that significant problems have existed in the design philosophy of Human System Interfaces (HSis).
There have been many studiet s a result of the THI accident and other incidents.
Utilitics ha.e implemented both NRC mandated changes and additional improvements on their own initiative.
However, the changes were formed based on the constrLints associated with backfits to existing Control Rooms (CRs) using eariy 1980s technology which limited the scope of corrective actions that might have been considered, i.e., more effective fixes could be used in the case of designing a new CR with the modern technology typical of advanced CRs.
Problems and issues encountered in similar systen of previous designs shall be identified and analyzed so that they are avoided in the development of the current system or, in the case of positive features, to ensure their retention.
Eqntent__of an Oneraling_b a rA gfLFlyh w:
Issues shall be identified for review and analysis.
Issues shall be tracked via the Human Factors Engineering Tracking System.
Human performance issues, aroblems and sources of human error shall be defined.
Design elements whica support and enhance human performance shall be identified.
Example issues:
Display Factors Alarm Factors Control factors Organization of Alarms Information Processing Factors Alarm Prioritization Comriunication factors Loss of Alarm Systems Training Factors Nuisance Alarms Procedurec Number of Alarms Staffing Factors Inoperable Instrumentation Content of Alarms Key Lock Switches Recorders Safety function Monitors functional Grouping Lighting Noise Equipment layout Coding Conventions Demarkation labeling Anthropometry Equipment layout Use of Normal Displays during Accident The operating experience review shall include both a review of literature pertaining to the human factors issues and operator interviews on the relevant issues identified.
