The inspector reviewed documentary evident that the welds had been repaired, reworked and reinspecte L. K. Comstock weld inspection report (WIR) checklists:

WIR 17569 documented completion of repairs on CC-23 WIR 11778 documented completion of repair / rework on CC-36 WIR 17570 documented completion of repair / rework on CC-87 WIR 11781 documented completion of repair / rework on CC-34 Sufficient documenting evidence including supporting documentation is on file to prove disposition of the weld deficiencies. This item is close (Closed) IDI Team Finding (456/85060-01): Different classes of conduit in contact with each other. Completion of Unit I walkdown of conduit systems in accordance with project instruction PI-BB-53 has been accomplished. Discrepancies identified during the walkdown have been j reviewed by the architect / engineer. Required analyses were performed

(Closed) Unresolved Item (456/85048-02; 457/85047-02): Testing of DC molded case circuit breakers. The inspector reviewed the architect /

engineer developed test plan for periodic verification of operability and testing of DC molded case circuit breakers. Under the test plan a representative sample of DC breakers will be tested to provide data for determining the optimum test frequency for molded case DC circuit breakers. Since the breakers are being tested during the interim test plan while a permanent test schedule is being developed. This item is close (Closed) Severity Level V violation (456/85036-02; 457/85035-02):

Inadequate cleanliness inside diesel generator junction boxes and air solenoid incorrectly mounted outside of the box and that the junction boxes have been acceptably cleaned. Review of Drawing 20E-1-4094C revealed that the latest revision shows the air solenoid as they are installed in the field and adequate cleanliness now exists. This item is close (Closed) Unresolved Item (456/84023-05; 457/84022-03): Final review and approval of installation records for instrument lines. The inspector reviewed the instrumentation retro fit verification program (IRV). The non-conformance report, NCR-715, issued-to address the instrumentation verification was closed on January 10, 1986. The inspector also reviewed CECO QA Surveillance Report 5373 performed to verify completion of the retrofit program. This item was also closed as a construction deficiency report, 10 CFR 50.55(e), in Inspection Report No. 456/86016. This item is resolve . Electrical / Instrument Cables and Terminations The inspector observed cable termination work in progress at panels on the 451 foot elevation. The cable was being terminated according to the termination card that had been issued to the electrician performing the termination. Wire strippers and crimping tools were within the calibration period stated on their affixed calibration sticker Appropriate drawings to assure that the proper cable was connected to the correct terminal was available at the work locatio The NRC inspector witnessed the performance of a quality control inspector (QCI) during the QC inspection of terminations in Cabinet 2PA 32-J-B The QCI's inspection was performed according to the approved termination procedure. The inspection included lug crimping, lug size and type, location, cable identification and color code. Inspection checklists were used and completed with appropriate notation The inspector reviewed cable document packages in the contractor vault for those cables included in the above observations. The packages included pull cards, termination cards, inspection reports and tool calibration reference .*

,

The inspector examined completed installation of two instrument panels and one motor control center ircluding component installation, cable entrances, separation and terminations. Cable terminations is the field were compared to the latest drawing revisions to determine whether the cables were terminated at the correct terminal, correct wire sized were installed, separation was according to design and proper fuses were installed. Deficiencies noted during the examination were two conductors on termination points different from the drawing, one missing fuse holder and an unmarked jumper. Discussions with licensee personnel revealed that.each of these deficiencies had previously been identified and documented by the licensee and that corrective action had been initiated but not complete No violations or deviations were identifie . Exit Interview The inspectors meet with licensee representatives (denoted in Paragraph 1)
