Unresolved Items t
Unresolved items are matters about which more information is required to t
'
determine;whether they are acceptable or may involve violations or devia-tions. New unresolved items identified during this inspection are discussed in paragraph Sa and Sb.
5.
Independent Inspection Effort (Units 1 and 2)
,
l l
The inspector conducted a general inspection of the Unit I and 2 contain-ments, auxiliary building, fuel buildings, and electrode issue stations to observe construction progress and construction activities such as welding, material handling and control, housekeeping and storage.
,
l l
a.
With regard to the above inspection the inspector accompanied by a
--
j-representative.of the licensee on September 23, 1981, noted a number of l
weld discrepancies on structured steel "B Frame" in the Unit 2 contain-
!
ment. At the time of this inspection, the extent of the discrepancies
!
or their acceptability to the code of record (AWS D1.1) could not.be
~ determined. The frame was fabricated by Southern Engineering Company.
The licensee documented the above in NCI No. 12892 and indicated that they would look further into the matter. The inspector stated that the above would be an unresolved item idantified as 414/81-20-02:
" Weld Discrepancies on Vendor Supplied Structures."
l b.
With regard to the above. inspection, the inspector noted that = Duke i
Procedure L-80, Revision 11, " Visual Workmanship Standards for. Welds'.'
i does not reflect the prohibition on piping porosity, in complete penetration groove welds, in butt joints transverse to the direction of computed tensile stress, as stated in AWS DI.1-Rev. 2-77 paragraph 8.15.1.7.
At the time of this inspection, the affect of the 'above acceptance criteria omission on previously inspected items could not be
,
L determined. The licensee indicated that they would look further into the matter.
The inspector stated the above would be identified as.
~
unresolved item No. 413, 414/81-20-03:
"AWS Acceptance Criteria Conflict."
.Within the areas ' examined no violations.or deviations were identified.

Reactor Coolant Pressure Boundary Piping (Unit 2)
l The inspectors observed non-welding'and welding work activities'for reactor coolant pressure boundary (RCPB) piping. The applicable ~ code'for:installa-tion of RCPB piping is.the ASME B and PV code,.1974 edition plus addenda through summer 1974.

Review of Non Welding-Quality Records i
The inspector selected various reactor coolant pressure boundary piping
~
components (e.g., pipe, fittings and welded-in components) for review of pertinent records to determine conformance with procurement, storage-and installation specifications and QA/QC site procedures.
Records of the following items were selected for review to -ascertain whether they (records) were in conformance with applicable requirements relative to the following areas: material test reports / certifications; vendor supplied NDE reports; NSSS quality releases; site receipt-inspection; storage; installation; vendor nonconformance reports.

Safety-Related Structures (Units 1 and 2)
The inspector observed field welding activities asscciated with safety-related structures and supports outside containment during.various stages of weld completion. Observations were made in order to determine whether the requirements of applicable specifications, standards, work and/or inspection procedures are being met for the activities involved and in the following stages of weld completion:
a.

-(a) With regard to the above inspection, the inspector, on September 23, 1981, noted that the veelding filler material
,
i issue station had issued three w31ders Type E-10018 elec-
L trodes in lieu of Type E-7018 electrtdes The Welding filler
'
material issue authorizations (Form H-3B) indicated that Type E-7018 was issued. The E-10018 electrodes went unde-tected by the issue station personnel, and the three welders.
The inspector identified the electrode type substitution at the work station of the welder of record for pipe support l
1-A-NV-32M. The licensee was able to account for all the L
improperly issued type E-10018 electrodes.
The licensee further determined that ncne of the Type E-10018 electrodes
'
had been used on production worL The above is Docomented in NCI 12892.
The above indicates that the licensee does not have adequate measures to control ' welding filler materials.
Failure to -
.
establish measures to control special processes including welding is in violation of~10 CFR.50 Appendix "B" Criterion-IX. This violation will be identified as 413, 414/81-20-01:
" Inadequate Measures to Control Welding Filler Materials."
(b) The inspector. examined weld joints where ~ welding was in progress to determine whether weld identification, weld procedures, welder qualification, weld material, defect removal (if applicable), specified NCE and' periodic checks of welding variables were in conformance with existing require-ments.
