Exit Interview The inspection scope and findings were summarized on September 5, 1980 with those persoca indicated in Paragraph 1 above. The inspector identified the areas inspected and discussed in detail the items of noncompliance and the unresolved items. No dissenting comments were received f rom the licensee.
3.
Licensee Action on Previous Inspection Findings (Closed) Deficiency 413, 414/80-15-03 " Failure to Document QC Welding Sur-veillance", Duke Power Company letter of response dated August 19, 1980 has been reviewed and determined to be acceptable by Region II. The inspector held discussions with the Project Engineer and examined the corrective actions as stated in the letter of response. The inspector concluded that Duke Power Company nad determined the full extent of the subject noncompliance, performed the necessary survey and follow-up actions to correct the present conditions and developed the necessary corrective actions to preclude recur-rc:ce of similar circumstances. The corrective actions identifiad in the letter of response have been implemented.
4.
Unresolved Items Unresolved items are matters about which rore iaformation is required to determined whether they are acceptable or may involve noncompliance or deviations.
New unresolved items identified during this inspection are discussed in paragraph 5e and 5.

Independent Inspection Effort Construction Activities (Units 1 & 2)
a.
The inspector conducted a general inspection of the Unit I and 2
-
containments, auxiliary building, fuel building, pipe fabrication shop and electrode issue station to observe construction progress and construction activities such as welding, material handling and control, housekeeping and storage.
b.
Post Weld Heat Treatment (Unit 1)
The inspector observed post weld heat treat (PWHT) activities on steam generator upper lateral support welded joint no.
1-1-A, accomplished in accordance with post weld heat data sheet C-8 Revision 0, Equipment Storage (Units 1 and 2)
c.
On September 3, 1980, the inspector accompanied by a repiesentative of the licensee made a general inspection of the staging area adjacent to the east side of the auxiliary building. The inspector noted six safety related valves, listed below, stored outdoors.

IND 091
C IBB 104
C IKD 30
C IBW 001

C Duke Quality Assurance Program Procedure P-3 Revision 12, " Storage Inspection", paragraphs 2 and 4.1.1 require storage to be in accordance wi th ANSI N45.2.2. ANSI N45.2.2-1972, " Packaging, Shipping, Receiving, Storage and Handling of Items for Nuclear Power Plants (During the Construction Phase), " Paragraph 6.1.2 (3) states " Level C iten.3 shall be stored indoors".
Paragraph 6.1.1 of ANSI N45.2.2, requires the above storage requirement to be in effect until the item is placed in its final location (e.g.,
installation). Duke Construction Procedure CP-371, Revision 3 " Pro-tection and Preservation of Installed Equipment", is the field imple-mentation procedure that establishes requirements to insure that equipment is adequately protected and perserved, from the time the item is removed from storage until after the item is installed.
Construction procedure CP-371 does not prohibit outdoor storage of Level C items.
Therefore the conflict bet een the program procedure and the implementation procedure appeared to result in the improper storage of six safety related valves.
Failure to establish adequate

-3-measures to control storage is in noncompliance with 10 CFR 50 Appendix
"B" Criterion XIII. This is an infraction and is assigned item No. 413, 414/80-24-01: " Inadequate Measures for Storage" d.
Welding Filler Material Centrol (Unit 1)
_
On September 3, 1980, the inspector accompanied by a representative of the licensee made a general inspection of the auxiliary building. The inspector noted an abandoned welder's pouch containing approximately 12 unused welding electrodes and bare welding rods.
Duke procedure H-3, Rev. 11 " Identification and Control of Welding Materials", para-graph 5.5.2 requires all unconsumed welding filler materials to be returned to the welding material issue station. Therefore, the welder issued the welding filler material failed to follow welding material control procedure.
The licensee documented the above occurance in Nonconforming Item Report No. 9391.
Failure to follow established procedures is in noncompliance with 10 CFR 50 Appendix B, Criterion V.
The inspector determined that the above was an isolated case. This noncompliance is being catagorized as a deficiency and was assigned item no. 413/80-24-02:
" Abandoned Welding Materials".
Prior to the completion of this inspection tha condition was documented and corrected.
Actions were taken to prevent recurrence. This is considered to be a no response required noncompliance.
e.
Chloride Control During the general inspection of paragraph Sa above the inspector noted several cans of "Winbro Tapfree" thread cutting fluid containing 1, 1, 1, Trychloroethane. At the time of this inspection it could not be determined whether the above material was consistent with paragraphs NB-4712, NC-4712 and NC-4712 of the ASME B and PV Code. In addition it could not be determined whether the licensee's site procedures addressed, the requirements of paragraph NB-4713, NC-4713 and ND-4713 of the AStE B&PV Code and the requirements of Paragraph C4 of Regulatory Guide 1.37.
The licensee indicated that they would look further into the matter. The inspector stated that the above would be an unresolved item and identified as 413, 414/80-24-03: " Chloride Control".
f.
Visual Inspector Qualification The inspector reviewed the Duke program for qualification of visual inspectors for compliance with ASME Code requirea.ents.
Article NB-5000, " Examination" of Section III of ASME, paragraph NB 5521 states, in part " Personnel performing nondestructive examination shall be qualified in accordance with SNT-TC-1 A..... For nondestructive exam-ination methods not covered by SNT-TC-1A documents, personnel shall be qualified by the Manufacturer or Installer to comparable levels of competency by subjection to comparable examinations on the particular method involved..... "
.
-
-4-The practical portion of the qualification shall be performed using the manufacturer's or Installer's procedure on parts representative of the Manufacturer's or Installer's products". Futhe rmore ; Article 1
" General Requirements", of Section V of ASME paragraph T-170 (b)
states, "When the referencing Code Sect. ion requires a manufacturer's Quality Assurance Program or Quality Control System and also specifies the use of examination methods not presently included in SNT-TC-1A (e.g., leak testing and visual examination), the manufacturer shall be responsible to develop training pregrams, written procedures, examina-tions, and practical demonstrations, equivalent to those required for the other examination methods covered by SNT-TC-1 A.
These shall establish the capability of the personnel to perform the required examinations" Paragraph 9.6. lf of SNT-TC-1A, June 1975 Edition requires personnel records of certified individuals to include as a minimum---descriptions of practical test objects. At the time of this inspection the formal personnel qualification record folders for welding inspectors (visual inspectors) did not include a description of the practical test objects.
The licensee stated that all the test cbjects were available for examination. The inspector noted the test object identification in the qualification record was not directly traceable to the test objects.
The licensee indicated that they would look further into the matter.
The inspector stated that the above would be an unresolved item identi-fied as 413, 414/80-24-04: " Description of Practical Test Objects".
In the areas examined, no items of noncompliance or deviationt except as described in paragraphs Sc and 5d were identified.
