ATTACHMENT The total number of Human Engineering Deficiencies (HEDs) identified at both North Anna and Surry and the various categories to which they've been assigned are shown in the table below.
By way of explanation, HEDs are prioritized for resolution into three groups - A, B, or C - based on an assessment of whether they rate high or low in three areas:
error potential, safety significance, and error consequences. A high rating in all three areas is Group A, in two areas, Group B, and in one or no areas, Group C.
Category Group A Group B Group C Resolved Total HUMAN ENGINEERING DEFICIENCIES Surry 80 237*

- Five HEDs are still under evaluation and are expected to be categorized as either A or B
- Because the North Anna review is incomplete, the potential exists for an additional 30-50 HEDs to be identified
