l As a result of the inspection conducted on February 10 through March 17,.1989, l and in accordance with 10 CFR Part 2, Appendix C-General Statement of Policy I

and Procedure for NRC Enforcement Actions . (1987), the following' violation was identified:

1 10 CFR 50,- Appendix B, _ Criterion V, as implemented by Commonwealth Edison Quality Assurance Topical Report, CE-1-A requires that activities'affecting-quality.be conducted by using approved procedures.' Commonwealth Edison

! Quality Procedure 10-51 requires that in-process inspections be performed at l designated hold points according to the maintenance procedure. Commonwealth bdison Quality Procedure 18-52, requires that GA perform surveillance of OC hold points.

Contrary to the above, on February 25, 1989, during performance of wurk request Z78896, OC performed an in-process inspection and OA performed a surveillance of the OC hold point. Both OC and QA signed off the hold point as acceptable without noting that weld 54 data had been recorded as weld #3.

CDIIgetive Action Taken_and-.Rennits_ Achieved:

The primary responsibility of assuring quality in each phase of work is given to all station personnel. The incorrectly identified welds were recognized by the second welder involved in the completion of the work request.

Upon discovery of the misidentified welds, a change was made to the weld map to change the weld numbers to agree with the data sheet. Subsequent to this, it was determined that the piping design table number was also different for the two welds. The requirements for the two design tables were evaluated and found to be identical. A Discrepancy Report (DR 22-89-0029) was initiated to document the error and to identify necessary corrective action.

Catrective Action to be Taken to Avoid Further_V_inlation:

Training discussions were held for the.affected departments (Mechanical Maintenance, Quality Control, and Quality Assurance) pertaining to weld map verification to stress the importance of assuring that the requirements of each work package are acceptably completed.

The training was completed on April 5, 1~989, and the DR was closed out on April 9, 1989. As noted in the Inspection Report, the affected assembly was not installed in the system. Instead, a second assembly was fabricated and correctly installed and documented. OA has reviewed their practice regarding surveillance of DC hold points and i~ound it to be acceptable. It is felt this is an isolated case and no further action is required.

DRe_When Full._ Compliance WillAMeh The station is in full compliance at this time.
