BEAVER VALLEY POWER STATION - UNIT NO. 2 DUQUESNE LIGHT COMPANY Interim Report No. 1 on Quality Control Acceptance of Conditions not Conforming to Inspection Plan Attributes and/or Drawings 1.
SUMMARY
During the preparation for cable pulling, it was established that the Quality Control (QC) Status Report, showing acceptance of Conduit 2CK606NA1 and Support 221-V-2 by QC Inspector "H", was not consistent with the cable raceway ticket status.
The installation was physically verified, and the referenced conduit and support had not been installed as required for QC acceptance.
Following this incident, it was then established that Conduit 2CX951BB had been accepted by QC Inspector "H"
under the following conditions:
was issued fo r a.
An outstanding Nonconformance and Disposition Report the support b.
A Construction Deficiency Report was outstanding for the conduit c.
The appropriate Reject Tags were attached to the conduit and support 2.
IMMEDIATE ACTION TAKEN Upon receipt of the above information, January 4,1983, all electrical inspection certifications held by QC Inspector "H" were cancelled, and a program of reinspection of the individuals work ove r a period of approximately three months was, initiated.
The results of that inspec-tion were received on February 16, 1983, indicating an unacceptable quantity of errors and omissions.
On receipt of the report, discussions were held with the Duquesne Light Company (DLC) Project Manager, Quality Assurance Manager, and Director potent ial Significant Defi-of QC; NRC Region I beirq informed of a ciency on February 17, 1983.
A reinspection program of work performed by three QC Inspectors in the same group was implemented to establish whether the problem was related to one individual or was widespread.
Below is listed the amount of reinspection performed and the results obtained.
Items Attributes Omissions Errors Inspector "H" 176 1,659 4
39 2.5 Inspector "W" 108 1,027 0
8 0.7 Inspector "B" 103 947 0
2 0.2 Inspector "S" 109 1,141 0
1 0.08
O The reinspection program was nost detailed and exacting, and examples of errors as described above are:
1 1/2 threads exposed in excess to the requirement i
- Flat washer not flat to mating surface Lock washer not fully flattened
- Material marking on nut found on reverse side Turned spring nut
- Lock washer installed in lieu of plain washer
- Support out of location by 1" or 1-1/2" The above listing is not a complete description of items found, but is a typical sample.
From the above inspection, we have drawn the following conclusions:
- a. The training of Inspectors was adequate.
- b. The failure of the individual, Inspector "H",
appears to be limited to an individual, and is not widespread over the inspec-tion group involved.
3.
DESCRIPTION OF DEFICIENCY Failure of QC supervision to adequately check on the performance of an individual inspector involved in the verification of conduit and associated support installation.
This failure was caused by a gradual shift in emphasis from QC field supervision to QC inspection status and scheduling.
4.
ANALYSIS OF SAFETY IMPLICATION i
i As our emphasis to date has been on establishing whether the failures and omissions reported were widespread, we have not had an evaluation performed of the results of the omissions and errors related to the hardware had they not been detected.
Although this evaluation has not been performed, we do consider that had the activities been allowed to i
i continue, the possibility of adversely affecting the safety of the
(
operation of the plant existed. An evaluation of the significant items discovered in our investigation will be performed.
5.
CORRECTIVE ACTION TO REMEDY DEFICIENCIES r
The individual, QC Inspector "H",
has been terminated.
Electrical installation work accepted by Inspector "H" will be reinspected.
1 I
The QC section dealing with electric inspection will be reconstructed as follows:
The QC Supervisor's and Lead Inspector's duties will be defined as a.
to be completely field oriented, with instructions regarding the sampling of Inspectors' work and performance at the point of work, b.
A group will be formed within the QC Department to deal solely with the scheduling, status reporting, N&D Report and CDR Report follow-up, and resolution of Engineering and Construction problems.
This action will be implemented prior to April 1, 1983.
6.
ADDITIONAL REPORTS A further report will be issued advising the results of the continuing reinspection of the work of QC Inspector "H", and also a more defini-t ive po s it ion regarding the significance of errors and omissions will be made.
It is expected that this report will be issued to the Region I Office by May 1, 1983.
