ng workload dimensions. e. The applicant should evaluate the acceptability of workload by comparing time and workload results to the established criteria. f. The applicant should evaluate unacceptable results to determine root cause and corrective actions. Additional Information: Note that the root cause of unacceptable workload for individual scenarios may not be due to staffing levels. For example, the high workload may be due to poor HSI design rather than insufficient staff. The human engineering discrepancy (HED) evaluation process described in NUREG- 0711, Section 11.4.4, can be used for this analysis. 7. Develop Conclusions about the Acceptability of Workload Levels a. Applicants should provide overall conclusions about the acceptability of workload levels and the basis for that conclusion considering: • Traditional methods are well-suited to clearly-defined situations, but are less well suited to analyzing unplanned and unanticipated situations, such as situations that have not been assessed by designers and not been experienced by operations experts. Yet it’s just these types of situations that can pose the greatest risk to safety. 18.0-45 Revision 3 – December 2016 • Both time and workload analyses • Consistency of results across the different challenging scenarios • The results of HED evaluations of any findings where workload fails to meet acceptability criteria REFERENCES 1.
