Electrical Control Panels and Cabinets Supplied by various Vendors INTERIM REPORT 3 DATE: April 28, 1983 PROJECT: Consumers Power Company Midland Plant Un!Ts 1 and 2 Bechtel Job 7220 Introduction This report provides interim status and the course of corrective action required pursuant to MCAR 66.
Description of Deficiency Unacceptable workmanship conditions, such as insufficient solder, broken wire strands, damaged wire insulation, leads pulling from lugs, loose identification tags and markers, use of improper wire lugs, and improper crimping have been identified on electrical ,
control panels and cabinets supplied by various vendors.
Probable Cause The cause for the deficiencies is being investigated and the results will be included in a future report. Preliminary results have been reviewed and no significant problems have been identified.
Summary of Investimation and Historical Backaround To date, 37 discrepancy reports (nonconformance reports (NCRs) and quality action requests (QARs)) have been written on electrical equipment as a result of MPQAD overinspections using Consumers Power Ccapany Project Inspection Plan 01-E-78. See Attachment 3 for a list and description of the NCRs/QARs associated with this NCAR.
Two additional NCRs (Attachment 3. Items 36 and 37) have been added to the scope of MCAR 66 since the issue of the last interim report.
Analysis of Safety Implications To date, 33 NCRs/QARs have been evaluated for possible impact on safety. For the cases analyzed, it is concluded that if the workmanship deficiencies had remained uncorrected, there would be no impact on the safety of operations at Midland. Four NCRs (Attachment 3. Items 34 to 37) see under evaluation. The 0346u I
-, w . . = _.,_, g.,w

responsible equipment vendors for Items 34 and 35 have been notified and were requested to perform an evaluation of whether the equipment can be expected to perform the. intended functions under the specified conditions. Based on vendor responses, Bechtel will perform a safety evaluation.- NCR Items 36 and 37 will be analyzed '
when they are received by Midland project engineering. Status results will be included in the next interim report.
Corrective Action A task force has been established to investigate and resolve NCAR
- 66. See Attachment 1 for the task force charter. As of the date of l this interim report, several corrective actions have been initiated I or completed. ,
i
- s. An investigation to summarize the deficiencies as noted on each of the NCRs/QARs has been completed and is included in this report as Attachment 2. Workmanship-related discrepancies are identified in Attachment 3.
! b. The task force has started reviewing each purchase order affected by this NCAR, and the results will be included in a future report. The task force has also reviewed the Bechtel NCRs that were assigned disposition and concurs with the dispositions. On near-term equipment deliveries where fabrication is complete or nearly complete, a comprehensive plan of shop inspection, coupled with a parallel MPQAD in-shop overinspection to detect and correct workmanship problems before shipment, is being implemented.
1
- c. Quality control has reviewed the source and receipt inspection program (reference: PQCI 7220/R-1.00, Rev 13) regarding vendor i
l workmanship. Based on the review, quality control believes that j the receiving program, as presently established at Midland, is adequate and no further action is required.
Reportability This condition was reported to the NRC by Consumers Power Company as potentially reportable on December 3, 1982.

- 1. Review the findings from MPQAD's (Plan 01-E-78) overinspections I
of electrical control panels and cabinets, and develop recommended plans of action for the Midland project and other divisional departments to avoid recurrence on future Midland l
l Plant purchase orders (
Reference:
MCAR Recommended Action Items B.2, B.3, C.1, and C.2).
- 2. Review and provide concurrence with project engineering dispositions so that there is a consistent approach used to '
l correct problems on existing hardware and to prevent problems on future work. Based on that review, the task force will produce a checklist to summarize the deficiencies for each purchase order. Project engineering, in support of the task force, will review each NCR and QAR and summarize the deficiencies noted on i
individual checklists for each purchase order. (
Reference:
MCAR Recossended Action Items A.1 and A.2) .
- 3. Develop a list of considerations to be used ir_ evaluating the individual purchase orders. The task force will then review each purchase order affected by this NCAR against the evaluation checklist (Step 2) and summarize the strengths and weaknesses of each purchase order (
Reference:
MCAR Recommended Action Items B.1 and B.2).
- 4. Identify the root causes of the workmanship deficiencies and develop plans for corrective action. (
Reference:
MCAR Recommended Action Items B.2, B.3, C.1, and C.2) .
- 5. Prepare a summary of corrective actions for individual purchase orders under Plan 01-E-7B where there will be future releases or where there is time in the fabrication process on existing items l
to implement changes. The Midland project will review, concur with/ resolve, and implement the corrective actions (
Reference:
( MCAR Recommended Action Items B.2, B.3, and C.2).
l
- 6. Develop a list of generic actions for purchase orders based on attributes other than those covered by Plan 01-E-7B. This list will be developed principally from the purchase order checklist and problem summary. The Midland project will implement the generic actions (
Reference:
MCAR Recommended Action Item C.2).
