5.
Independent Inspection Effort The inspector made a general site inspection to observe storage, a.
housekeeping and construction progress.
b.
The inspector reviewed twenty-three radiographic films for Unit I containment welds for conformance to procedure and Code requirements.
Procedure No. NDE-10, Rev. 3, " General Radiography Practice" is the applicable site procedure. The applicable code for fabrication and inspectica of containment is the ASME Boiler and Pressure Vessel Code, 21.67'099
. - F-2- \\ Section III, Subsection NE, 1974 Edition plus addenda through summer 1976 and Code Case Nos. 1714 and 1777.
Films reviewed were as follows: Weld No.
Film No.

Steel Structures and Supports - Observation of Welding Activities Within Containment (Unit 1) The applicable Code for containment welding is delineated in para-a.
graph 5.b.
Applicable requirements are contained in Duke Specifica-tion PEIS-1144.10-00-0001, " Specification For Field Welding and Erection of Containment Vessel"; Construction QA Procedure M71, Rev. O, " Process Control and Inspection of Containment Systems and Liner Plate"; Construction Procedure L300, Rev. 5, " Shielded Metal Arc Welding Process Specification" and Construction Procedure L500, Rev. 7, " Flux Cored Arc Welding Process Specification." The inspector observed fitup, root welding and intermediate welding of containment Weld Nos. 11023B and 11024B for conformance to procedure and Code requirements. Areas reviewed included conduct of work in accordance with an approved traveler, conformance to procedure parameters and drawings, welding technique including sequence, weld joint geometry and cleanliness, fitup tolerance, control of welding electrodes, condition of welding equipment, periodic checks of welding variables and performance of required inspections.

, P-3- \\ b.
On October 11, 1979 documentation of welding parameter surveillance inspections of Unit I containment welds were not available.
Duke Construction QA Procedure M-71, Rev. O, Paragraph 4.11.B requires a welding inspector to perform periodic welding surveillance of attri-butes such as voltage, amperage, travel speed and interpass temperature and also requires the inspections to be documented on Form M-71F.
Interviews of QC and welding personnel and observation of welding activities conducted by the NRC inspector indicated that surveillance was being performed and procedure variables were being complied with.
This is in noncompliance with 10 CFR 50, Appendix B, Criterion XVII, as implemented by DPC Topical Report paragraph 17.1.17 which requires sufficient records to be maintained to furnish evidence of activities affecting quality. This is Deficiency 50-491/79-18-01 - Failure to document welding surveillance.
No items of noncompliance or deviations, except as identified in paragraph 6.b., were identified.
7.
Steel Structures and Supports - Welding Material Control (Units 1, 2 and 3) The applicable Code for welding material is the ASHE Boiler and a.
Pressure Vessel Code, Section III with latest edition and addenda in effect at tl'e time of order.
Site requirements are contained in the QA Manual for ASME Code Work, Section E-3, Rev. 9, " Field Procurement of Items and Construction Services"; QA Procedure H-3, Rev. 10, Identification and Control of Welding Material"; QA Procedura P-1, Rev. 19, " Receiving Inspection"; QA Procedure P-3, Rev. 9, " Storage Inspection"; Construction Procedure CKD-6, Rev. 1, " Reconditioning of Law Hydrogen Coated Electrodes"; and Construction Procedure CKP-8, Rev. O, " Supplementary Requirements fcr the Control of Welding Filler Material." The inspector reviewed the above procedures to determine if the licensee has established adequate procedures for purchasing, receis_ng, storing, distributing, identifying, handling, and moisture control during storage and field use. The inspector observed each of three welding material issue stations to determine if requirements were being me' for storage, issue, identification and reconditioning of welding materials.
The inspector also observed welding areas for control of welding filler caterials.
In addition, the inspector reviewed welding material records to determine of Code required tests were being performed.
Records for the following materials were reviewed: Filler Metal Type Size Lot / Heat No.
E7018 1/b 47J E70S-2 1/8 77405 E309-16 1/8 SG136 2167 101
-. . t-4-s Filler Metal Type Size Lot / Heat No.
ER308 3/32 435489 Type 308 1/8 D3426T308 Consumable Insert E70T-1 1/16 1341-15 E70T-1 1/16 H7638 b.
On October 11, 1979 many Type 7018 welding electrode stubs were present in an unmarked trash can in the Unit I containment fabrication Construction Procedure CKP-8, Rev. O, paragraph 4.6 requires area.
that all electrode stubs be returned to rod issue stations and deposited in marked containers. There was no evidence that the welding material had been utilized out of the trash can.
This is in noncompliance with 10 CFR 50, Appendix B, Criterion V, as implemented by DPC Topical Report paragraph 17.1.5 which requires activities affecting quality to be accomplished in accordance with established procedures.
This is Deficiency 50-491/79-18-02 - Failure to follow procedure for control of welding filler metal.
No items of noncompliance or deviations, except as identified in paragraph 7.b, were identified.
6.
Steel Structures and Supports - Weld Heat Treatment (Unit 1) The applicable Code is delineated in paragraph 5.b.
General heat treating requirements, includ.ing preheat are contained in QA Procedure L-50, Rev. 5, " General Specification for Heat Treatment of Weldments." Preheat signoff is provided for on the weld traveler.
Specific preheat temperatures are provided on each Field Weld Data Sheet.
The inspector reviewed the above documents to determine if adequate approved procedures were available to control weld preheating.
The inspector also observed preheating activities on Unit 1 containment Weld Nos. 11023B and 11024B at various stages of completion to determine if procedures were being followed.
No items of noncompliance or deviations were identified.
9.
Steel Structures and Supports - Welder Qualification (Units 1, 2 and 3) The applicable code for welder qualification is the ASME Beiler and Pressure Vessel Code, Section IX, latest edition and addenda in effect.
Controls are provided in QA Procedures 1-1, Rev. 7, " Qualification of Welders and Welding .erators" and L-900, Rev. 9, " Coupon Testing Require- , ments for Performan.e and Welding Procedure Qualifications." The inspector reviewed the above procedures to determine whether adequate procedures were available to control initial qualification of welders, requalification, maintenance of qualification and records of these qualifications.
The inspector also reviewed 19 qualification records for five welders of record for Unit I containment Weld Nos. 11023B and 11024B for conformance to procedure and Code requirements.
No items of noncompliance or deviations were identified.
