!. identified during subsequent back-EMF testing when the inner and outer

!' . races separated causing the ball bearings to fall cut and the second stage gear to move toward and rub against the drum support.

3. Administrative Procedure Q-15, " Control of Nonconforming Items,"

Issue 3, dated June 23, 1982, requires for an NCR disposition involving repair, that the SQAS determine and denote on the NCR any appropriate inspections that may be requied and the organization responsible for performing such inspections, and sign the appropriate block.

Contrary to the above, on March 5, 1985, the NRC inspectors determined from a review of previously processed nonconformance reports (NCR) addressing control-rot-drive-refurbishment repairs, that the superin-tendent of QA services (SQAS) had not denoted the appropriate inspec-tions and responsible organization. The NRC inspectors were unable to identify what QC requirements were used for repairs which affect quality.

This is a Severity Level IV Violation. (Supplement I.D.)
