10CFR50, Appendix B, Criterion XVI required in part that measures shall be established to assure that
conditions adverse to quality are promptly identified and corrected.
Significant conditions adverse to quality must be corrected to prevent recurrence. Contrary to the above, from 2006 to May, 2014, the licensee failed to prevent recurrence for a significance
condition adverse to quality in that the licensee did not establish corrective actions for standby
lube oil conditions that contributed to three
DG bearing rotations discovered during maintenance inspections on the 1A and 2A
DGs. The inspectors determined that the violation was of very low safety significance (Green) because the rotated bearings did not prevent the
DGs from performing their safety function. The issue is documented in the licensees corrective action program as
PIP C-14-2352.
