Introduction This report provides the final status of Bechtel action pursuant to MCAR 50.

Description of Potential Discrepancv Subsequent to field testing of 200 A thermal magnetic circuit breakers, engineering disccvered that the installed power cable brands were not listed on the bill of material in Reference A.

Random inspections by site personnel identified eight different brands of power wiring and two brands of control wiring installed in Q-listed motor control centers (MCCs).

None of the wiring brands identified during these inspections are in-cluded in Reference A.

Other Q-listed equipment supplied by the vendor was inspected. Control wiring was discovered in 4.16 kV switchgear, which is not included in Reference B.

Bechtel suspected that all Q-listed MCCs and 4.16 kV switchgear delivered under Purchase Orders 7220-E-7 and 7220-E-205, respectively, may contain cable with inderminata qualification status.

Corrective Action t

1.

Inspection of delivered equipment for the purpose of identifying and tracking suspect cable by additional nonconformance reports (NCRs) till not be required based,on the following:

It has been confirmed that the w' ring installed in all delivered i

a.

MCCs is presently not included in the qualification report.

Be-cause of omission of the qualification data, the status of the Reference A has been revised by Bechtel to a Status Code 3:

" Revise and resubmit. Work may proceed subject to incorporation of changes indicated." NCR 1749 remains open on MCC qualification and will serve as the tracking requirements to ensure compliance.

b.

Reference B, which contains qualification data on a]* vendor-supplied cable, has been reviewed, accepted, and given a Status Code 1:

" work may proceed."

2.

a.

All installed cable in Gould-supplied Class lE motor control centers will either be qualified or replaced based on acceptance of the revised qualification reports and dispositioning of NCR 1749.

b.

Class lE 4.16 KV switchgear wiring has been qualified (refer to Corrective Action Item lb).

3.

A " hold shipment" has been placed on all undelivered Gould Class lE equipment. A Bechtel supplier quality representative will verify that the installed materials are in ac cordance with the respective qualification report as identified by engineering prior to release for shipment.

This hold will be remove d af ter Bechtel acceptance of the Gould qualification report.

4.

An audit to evaluate the adequacy of Gould's quality assurance pro-gram at the MCC facility was completed on June 5, 1981. A similar evaluation at the 4.16 kV switchgear facility was completed July 17, 1981. No problems were identified involving the qualificaticL pro-cess at either facility (see References C and D).

5.

As stated in Corrective Action Item 4, the quality assurance ade-quacy evaluations have been completed with positive results.

Restrictions on procurement of new items are therefore removed.

MCAR 50 Final Report 039I5S August 11, 1981 Page 3 6.

Could Inc., Electrical Apparatus Division (MCC), has identified the cause of the problem as an oversight in preparing Reference A root because of a change in the bill of material format. As a result of this problem Gould has improved controls for assuring consis-tency between engineering documents, hardware, and qualification reports. Could has assured that wi'e qualification was always intended to be provided (refer to Corrective Action Item 7 for comple-tion schedule).

The Brown Boveri Electric, Inc. (Gould) Switchgear Systems Division has stated that the problem was a result of an editorial error while preparing the IEEE Std 323-1974 qualification report submitted fn 1980 which fai1.ed to identify the wiring used in manufacture of sd tchgear prior to 1978. A revised report has been submitted (refer to Corrective Action Item lb).

7.

The remaining action is Gould's resubmittal of the MCC qualification report Mth qualification data for a.ll supplied cable.

This report is scheduled for submittal on October 5,1981.

Safety Imp lications The unc,ualified wiring is installed in the power and control circuitry of Class lE 460 V MCCs and in the control r.ircuitry of Class lE 4.16 kV switchgear.

Insulation meterial failure.iuring the qualified life of the equipment due to sh ng and irradiation effects could prevent the proper i

operation of safety load groups.

Based on the possible safety implication, this discrepancy has been reported in accordance with the Code of Federal Regulations, Part 50.55(e).
