Licensee Ac' tion on Inspector Followup Items (IFI)
a.
(Closed) IFI 491/80-04-02; Weld Electrode Control Procedure Revision.
The licensee has revised procedure H-3 " Identification and Control of Welding Material", to described more accurately storage of weld rod in the field.' The revision (Rev. 11) states that issued material shall be kept in suitable rod pouches. A field inspection verified implemen-tation of this revision.
b.
(Closed) IFI 491/80-04-03; Containment Weld Radiographs. The licensee
~
is now performing periodic QA surveillances on containment weld radio-graphy in order to provide objective evidence that individual welds are being radiographed as required. These surveillances are documented on Form QA-300B Rev. I as required by procedure QA-300 Rev. 7 Construc-tion Surveillance.
6.
Independent Inspection Effort Heavy rains and resulting wet conditions precluded field construction activities on the containment vessel. Hence all inspection activities were restricted to review of quality records, procedures, radiographs and closing of inspector followup item o.

a.
Radiographic Film Review The inspector reviewed selected radiographic films for Unit I containment welds for conformance to procedure and code requirements. Procedure No. NDE-10, Rev.
4, " General Radiography Practice" is the applicable site procedure. The applicable code for fabrication and inspection of containment is the ASME Boiler and Pressure Vessel Code,Section III, Subsection NE (74S76) with code cases 1714 and 1777 being applicable.
Films revi,ewed for this work were as follows:
Weld No.
Film No/RT Stations I-10915-D Basemetal 0-1, 2-3 I-10915-C Basemetal 0-1, 2-3 I-10920-B Entire weld No items of noncompliance or deviations were identified.
b.
QA Surveillance of Containment Fabrication Periodic QA surveillance of containment fabrication, erection and process control activities is performed under provision of Surveillance Procedure QA-300 Rev. 7.
The findings are documented in Form QA-300A Rev. 2 as required. Records of surveillances performed in this area between 5-7-79 to the present were reviewed for completness, accuracy and timely resolution of findings identified.
c.
Stud Welding Construction Procedure CKB-6 Rev. 1, " Stud Welding of Stainless Steel, Structural Steel and Miscellaneous Steel Construction for Nuclear Services", provides requirements for steel welding in accordance with AWS Structural Welding Code D1.1-75. Procedure M-21 Rev.10 established inspection requirements for stud welding on safety-related structures.
It provides for inspections before, during and after welding and for acceptance of stud assemblies. A randomly selected sample of product certifications and receipt inspection reports for material on hand was reviewed for compliance with the aforementioned code, completeness and accuracy. These quality records were for material on order numbers 920553, 904165, 820532 and 807133. Within these areas the inspector noted that the manufacturer's stud base qualification reports, discussed under 4.26 and 4.31 of the aforementioned code were not available for review. The licensee representative agreed to look further into this
,
l matter. This was identified as IFI No. 491/80-08-01, Stud Base Qualifi-l cation Report.
