Gentlemen:
SUBJECT:
INSPECTION NO. 50-369,370/86-20
Enclosed is the report of the team inspection conducted by Mr. S. D. Alexander
and
other
NRC
representatives
during
the
period
of July
28
through
August 1,1986 at your engineering offices in Charlotte, North Carolina and at
the McGuire Nuclear Station, of activities authorized by NRC License Fos. NPF-9
and NPF-17.
The team's findings were discussed with you and members of your
staff at the conclusion of the inspection. The inspectors reviewed your imple-
mentation of a program as required by 10 CFR 50.49 for establishing and
maintaining the environmental qualification (EQ) of electrical equipment within
~
the scope of 10 CFR 50.49.
Within these areas, the inspection consisted of
examination of selected procedures and records, inspection of selected plant
equipment, interviews with personnel, and other observations by the inspectors.
The inspectors determined that you have implemented a program to meet the
requirements of 10 CFR 50.49 except for certain deficiencies identified in the
enclosed inspection report.
Seven (7) of these deficiencies, summarized in
Appendix A, are classified as Potential Enforcement / Unresolved Items and will
be referred to the NRC Region II office for further action.
One deficienc
involves unqualified wiring in Limitorque motorized valve actuators (MOV)y
'
.
Other Potential Enforcement / Unresolved Items include the presence of gear case
'
grease relief shipping caps on Limitorque MOVs inside containment, documen-
tation which did not support qualification of Rockbestos silicone rubber
insulated cable or Barton 386A transmitters or Samuel Moore PVC insulated cable,
Raychem splices in unqualified configurations (bent and over braid) and failure
to document functional performance requirements for cable,

Three additional concerns are classified as Open Items, and a future NRC
inspection will review your actions concerning them.
Details of all the
deficiencies and concerns are discussed in the enclosed inspection report.
Your letter of August 15, 1986 provided your positions on the Potential
Enforcement / Unresolved Items as discussed at the exit meeting at the close of
the inspection and described your actions taken to address those items up to
that date.
The information provided was taken into consideration and, subject
to verfication in a future inspection, may aid in resolving some of the issues.
Completion of corrective actions regarding the identified deficiencies and
concerns should not be delayed pending either a future NRC inspection or
further action by the NRC Region II Office.
We are available to discuss any questions you may have concarning this
inspection.
Sincerely,
.

APPENDIX A
Potential Enforcement / Unresolved Items
As a result of the equipment qualification inspections during the period of
July 28 - August 1,1986 at the Duke Power Company (DUKE) engineering offices
and the McGuire Nuclear Generating Station (McGUIRE), the following items have
been referred to the NRC Region II office as Potential Enforcement / Unresolved
Items.
(Paragraph references in parentheses are to detailed portions of the
inspection report.)
1.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and section 5(1) of
NUREG 0588, Category II, qualification documentation for Limitorque
motorized valve actuators (M0V)
(e.g.,
TAG Numbers IVX0001A and 28,
1RN0086A, INSSV5560 and 5570, ICA0038B, 50B, 54AC, and 66AC, 2PN0187B and
2RN0297B) did not establish similarity between installed internal control
wiring and qualified wiring in that the installed wiring was not identi-
fied and thus not traceable to qualification documentation.
(Paragraphs
4.A(1) and 4.E(2) through 4.E(7), Item 50-369,370/86-20-01)
2.
Contrary to paragraphs (f) and (k) of 10 CFR 50,49 and section 5(1) of
NUREG 0588, Category II, the qualification documentation for Limitorque
MOVs (TAG Nos.: 1VX0001A, IVX0002B, INSSV5570, ICA00508, ICA0054AC, and
'
ICA0066AC) did not establish similarity between installed MOVs and those
tested in that, unlike those tested, the gear case grease reliefs on the
,
installed MOVs were covered with shipping caps thus impairing their
ability to function. (Paragraphs 4.E(2), (4), (5) & (8), Item 50-369,370/
86-20-02)
~
3.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and section 5(1) of
NUREG 058.8, Category II, cualification documentation for Raychem, WCSF-N,
cable splice insulation sleeves required to be qualified at McGUIRE did
not establish similarity between installed splices and those tested in
that some were bent such that the bend radius was significantly less than
the minimum tested and/or allowed in the manufacturer's specifications and
others were installed over braided jacket material unlike tested splices
and contrary to the manufacturer's specifications.
(Paragraphs 4.A(1) and
4.E(9), Item 50-369,370/86-20-03)
4.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and sections 2.2 and
5(1) of NUREG 0588, Category II, qualification documentation for cables
did not demonstrate that the cables met performance requirements for their
plant applications in that appropriate functional performance requirements
were not established.
(Paragraphs 4.A(1) and
4.0,
Item 50-369,370/
86-20-04)

5.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and Sections 2.2, 2.4
and 5(1) of NUREG-0588, Category II, DUKE had not established qualifica-
tion for safety-related Barton 386A pressure transmitters in that (a) test
anomalies were not satisfactorily explained and shown not to indicate
common mode failure and (b), no other qualification data was provided
although original results were rendered inconclusive.
(Paragraph 4.D(1),
Item 50-369,370/86-20-05)
6.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and Sections 2.2, 2.4
and 5(1) of NUREG-0588, Category II, qualification was not established for
Rockbestos "Firewall SR" silicon rubber insulated' cable in that the
cable's qualification was based solely on existing Rockbestos test reports
which are considered inclusive (as discussed in IE Information Notice 84-44) and there was no additional information.or analysis in the file to
augment the original test reports or demonstrate qualification indepen-
dently.
(Paragraphs 4.A(1) and 4.D(2), Item 50-369,379/86-20-06)
7.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and Sections 2.2, 2.4
and 5(1) of NUREG-0588, Category II, qualification was not established for
Samdel Moore (Eaton) polyvinylchloride (PVC) insulated cable in that the
basis for qualification was the presumption of generic material similarity
between the Samuel Moore PVC and Brand Rex PVC (for which a qualification
test report was in the Samuel Moore EQ file) without supporting analysis
or test data.
(Paragraph 4.D(3), Item 50-369,379/86-20-07)
