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,

Duke Power Company -2- December 1, 1986

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)
