2.
Exit Interview The inspection scope and findings were summarized on August 14, 1979 with those persons indicated in Paragraph I above. The inspector identified the inspected and discussed in detail the item of noncompliance. No areas dissenting comments were received from the licensee.
3.
Licensee Action on Previous Inspection Findings Not inspected.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort a.
Construction Activities (Units 1 and 2) The inspector conducted a general inspection of the auxiliary building, containments Units 1 and 2, and pipe storage areas to observe constructior progress and construction activities such as welding, material bandling and control, housekeeping and storage.

Radiographic Examination (Unit 1) The inspector reviewed randomly selected radiographs of safety related pipe welds. The applicable code for fabrication and inspection of safety related piping is the ASME B and PV Code, 1974 edition plus addenda through Summer 1974.
The inspector reviewed radiographs to verify that the following attributer were consistent with code and procedural requirements.
Required penettameter type, size, placement
.
Required penetrameter sensitivity
.
Required film density, density variation
.
Film identification
.
Acceptable film quality

Radiographs of the following joints were reviewed:

Pipe Storage During an inspection of the piping fabrication shop laydown area the inspector noted seven stainless steel pipe spools with red iron oxide
-
on and adjacent to the fabrication welds 360' extending one inch and greater from the weld on the base material which apparently resulted from the use of carbon steel contaminated grinding wheels or wire brushes during fabrication.
The preceeding is contrary to CP-170, Rev. 6 " Handling of Piping Materials and Components" paragraph 4.3b which prohibits the use of carbon steel contaminated grinding wheels or wire brushes on stainless steel. Upon notification, the licensee issued NCR No 6442, conducted training for the personnel concerned and removed the oxide from the seven spools. The inspector and the licensee were unable to identify any additional examples installed, in fabrication, or in storage.

Failure to follow Materials Handling Procedure is in nonconformance with 10 CFR 50, Appendix B, Crtierion V.
This is a deficiency and was assigned item no 413-414/79-17-01: Failure to follow materials handl-ing procedure.
This item was downgraded from an infraction to a deficiency since future licensee cleanliness inspections would have corrected the above problem prior to installation.
In discussing this matter with the licensee the inspector stated in view of the completed corrective action no licensee response would be required.
d.
Welding Operator Qualification As a result of Authorized Nuclear Inspector (ANI) report of July 26, 1979 concerning control of welding machine settings and the corresponding DPC-NCI, the inspector reviewed the applicable procedur es and discussed the same with the licensee.
However in that this matter (control of welding machine settings) was not specifically addressed in the procedures the inspector requested and the licensee agreed to look further into the matter and report their findings to the inspt.or at a later date.
This was identified as inspector follow up item no. 413-414/79-17-02:
Control of welding machine settings.
e.
Welding Procedure Review The inspector discussed the open item of noncompliance identified at the Cherokee site, cited against the " Duke Power Company Construction Department Quality Assurance Program" (DPC-CD-QAP) and reported in RII:WPK 50-491-492-493/79-12 " Failure to include nonessential varia-bles in GTA Welding Procedure Specifications". In view of the program-matic nature of the nou,mpliance and the fact that at the time of this inspection corrective action had not been implemented with regard to the Catawba copies of the (DPC-CD-QAP), the inspector stated that this would be an inspector follow up item no. 413-414/79-17-03 " Failure to include nonessential variables in GTA Welding Procedure Specifica-tions.
The licenste's planned corrective action will be reviewed at a later inspection.
6.
Containment (Structural Steel Welding) - Observation of Work and Work Activities The inspector observed field welding activities associated with steel containment structures and steel supports for major equipment within the containment at various stages of w
'_1 completion.
The applicable Code for containment / support welding isSection III of the ASME B and PV Code,Part MC,1971 edition with addenda through Summer 1972.
The inspector observed welding activities where joint 'itu
.nd align-a.
ment were complete (but welding had not been started) to determine 118LJ ni5

The inspector observed welding activities where welding was in progress to determine conformance with specifications and procedures in the areas of: weld identification, specified weld procedures, qualified welders, specified weld material, specified purge (if applicable);
repair procedures, specified NDE being performed and periodic checks of welding variables.

d.
Du-ing observation of welding activities taere did appear to be a sufficient number of qualified inspection personnel at the work site.
Within the areas examined, there were no items of noncompliance or deviations identified.
7.
Safety Related Piping (Welding) - Observation of Work and Work Activities The inspector observed field welding of safety related piping outside the reactor coolant pressure boundary at various staaes of weld completion.
The applicable Code for safety related pipe weldint is listed in Paragraph 5 above.
The inspector examined weld joint fitup, prior to welding, to deter-a.
mine whether veld identification / location, joint preparation and alignment, evidence of QC verification meet applicable procedures. The following weld joint was examined.

24"x0.375" Refueling Wate; The inspector examined weld joints where welding was beyond the root c.
pass to determine: weld / welder identification, qualified welder / weld procedure, periodic checks of welding variables, use of specified weld material, proper interpass temperature and where applicable preheat and postweld heat treatment and physical appearance of weld (e.g.
starts, stops, undercut and surface imperfections).
The following weld joints were examined.
