[Hij l At 2200 on 6-9-82, it was determined that "A" train _ and "B" train __Seryice_. water _ cooling ]

g j q [ valves associated with the swing charging pump were mislabeled i.e. "A" train marked as_j g g ["B" train and vice versa. As a result, the swing charging pump may have failed under I gjg [certain postulated accidents as described in the FSAR. An extensive investigation _j

[ g l revealed that since initial operation of Unit 2, the swing charging pump was designated j as one of two operable charging pumps only during the period from 5-1-81 through 5-18-81.
