SUMMARY
Inspection on June 18-21, 1979
Areas Inspected
This routine unannounced inspection involved 25 inspector-hours onsite in the
areas of safety-related 125VDC battery storage and maintenance QC records;
safety-related motor-operated valve electrical control circuits; and safety-
related power cable installation and QC records.
Results
Of the three areas inspected, no apparent items of noncompliance or deviations
were identified in two areas; one apparent item of noncompliance was found in
one area (Deficiency 413/79-12-02 and 414/79-12-02, Failure to follow Quality
Assurance Program Procedure P-1, " Receiving Inspection").

Independent Inspection
The inspector selected the electrical control circuits for containment
isolation valve numbers IKC 320A of the component cooling system and
INC 056B of the pressurizer relief tank spray system for review. The
circuit interface between the valve's operating circuit components and
tile status monitoring circuit components was examined in detailed.
Storage, maintenance, and receipt inspection QC records for safety-related
125V DC battery number 1 EBB were reviewed.
The QC records were examined
to assure that they were complete, legible and retrievable.
Within the areas examined, there were no items of noncompliance or devia-
tions identified.

Electrical (Cables and Terminations I) - Observation of Work and Work
Activities
The inspector selected the ten power cables listed below for examination:
1*EPL 501
1*RN668
1*EPE 529
1*EPE 501
1*EPE 530
1*EPC 526
1*RN 501
1*EPC 525
1*RN 669
1*EPC 524
Cable storage, handling, identification, and use of specified material
were in accordance with Quality Assurance Program (QAP) Procedure P-1,
" Receiving Inspection".
Cable size, type, location, routing and pulling
were in accordance with QAP Procedure M-40, " Electrical Cabl.e Installation
and Inspection".
Within the areas examined, there were no items of noncompliance or deviations
identified.
8.
Electrical (Cables and Terminations I) - Review of Quality Records
The QC records for the power cables listed in paragraph 7 were examined
in the areas of receipt inspection, material certification, and instal-
lation.
A review of vendor certification records for cables 1*RN668 and 1*RN 669
revealed that Duke Power Company's (DFC) Form 930.1, " Vendor QA Certifica-
tion" required to be filled in by the vendor for each cable reel contained
The forms (930.1) specified conformance to DPC specification
an error.
CNS 1354.01-00-0003, " Single conductor and multi-conductor 2KV Power
Cable", instead of DPC specification CNS 1354.01-00-0001, "15 & 8 KV

Power Cable Multi-Conductor".
Further examination of QC records for
other cable reels purchased per the same purchase requisition number
(8337-1354.01-00-0014) revealed that the Form 930.1 for nine cable reels
contained the same specification error. This er.or was not detected by
the project QA staff during review and acceptance of vendor records per
Quality Assurance Program (QAP) Procedure P-1, " Receiving Inspection".
THe "QA Records Acceptable" block on the Form P-1A's, " Receiving Inspection
Report", documenting receipt inspection of the nine cable reels had been
signed by the project QA staff personnel on May 22, 1979.
Additionally, the inspector noted the "QA Records Acceptable" block on
another Form P-1A for five cable reels purchased per the same purchase
requisition number (8337-1354.01-00-0014) was signed by a site QA engineer.
QAP Procedure P-1 requires this block to be signed by the project QA
staff.
The licensee informed the inspector that the QA engineer's signature was
a co-signature for the QA records acceptance block.
This co-signature
allowed the site QA engineer to release the cable for issue.
The licensee
also stated that the co-signature is not recognized by tae present QAP
Procedure P-1, but that a proposed revision to the procedure which is
presently being reviewed would eliminate the need for a co-signature.
The two examples listed above are indications that the instructions of
QAP Procedure P-1 are not being followed.
This is a deficiency and is
identified as items 413/79-12-02 and 414/79-12-02; Failure to follow
Quality Assurance Program Procedure P-1, " Receiving Inspection".
The inspector reviewed the vendor supplied cable test reports in
conjunction with DPC Spec. CNS-1354.01-00-0001 to assure the required
cable certification tests had been performed.
During discussions with
the licensee, the question of what cable certification tests were
applicable to each type of cable listed in the specification was raised.
The licensee agreed to review the specification and provide additional
inf ormation.This item will be identified as unresolved item 413/79-12-03
and 414/79-12-03; Engineer Specification requirements for vendor certifi-
cation test.
