Steel Structures and Su'pports - Observation of Welding Activities Outside Containment (Units Al and A2)

a.

The inspector observed field welding of steel structures at various stages-of weld completion. The applicable code for this welding is the AWS Structural Welding Code DI.1, Revision 2-74.

The following welds were observed:

The inspector observed the work to determine whether:

(1) Work is conducted in accordance with a document which coordinates and sequences operations, references procedures, establishes hold points, and provides for producation and inspection approval.

(2) Weld identification and location are as spect'ied.

(3) Procedures, drawings, and other instructions are at the work stations and readily available.

(4) WPS assignment is in accordance with applicable code requirements.

During observation of the stud welding in the Unit A2 control building identified above, the inspector noted the following problems:

(1) The inspector requested the stud welding procedure covering the work in progress. The personnel performing the work did not have a copy of the procedure and could not locate a copy.

After searching for some time, a copy of the work package was found. In review of the work package, B262-C2, the inspector noted that no reference was made to the stud welding procedure or the QCI for inspecting the stud welds. Project Engineering later determined that this lack of i eference to stud welding procedures in the work package also applied to other work packages (C-022-C2, C-268-C2, and B-020-C1) for str uctural steel. Paragraph 2 of revision 5 to CEP 5.04, " Work Packages", requires that documents, quality control instructions, and other special instructions and/or procedures nacessary to perform the work be identified in the work package. Additionally, discussiors with the QC inspector and stud welding personnel revealed that tne two pre production test stud welds for the work observed by tte inspector had not been made as required by paragraph 3.0 of QCI N-504, Revision 0, " Stud Welding, AWS, Examination and Testing".

Failure to reference procedures for stud welding in the work package and failure to comply with tesr.ing requirements of QCI N-504 is considered to be in violation of 10 CFR 50, Appendix B, Criterion V and is identified as item number 520/81-15-01, Failure to follow procedures for stud welding.

(2) During rev;ew of QCI N-504, the inspector noted that the procedure is not clear as to when the inspection requirrtents for shear connectors apply and when the inspection requirements fer concrete anchors apply.

Paragraph 2.0 of the QCI indicates that differ-entiation between shear connectors and concrete anchors cannot be

made at the construction level and unless design drawings speci-fically ideritify welded studs as one or the other, studs are to be tested-as " unidentified".

However, the field considers that the parts are identifiable as sheer connectors o concrete anchors based on the vendor's catalog number.

The licensee agreed to clari fy this matter, which will be identified as inspector follewup ' item 520/81-15-02, C1arification of stud welding inspection requiren.en ts.

Within the areas inspecte.', no violations, except as identified in para-graph 8.b.(1), or deviations were identified.

Inspector Followup Item;,

(0 pen) Inspector Followup Item 519/80-01-01, MT Indications on Anchor /

Darling Globe Valve.

The licensee has obtained the radiographic film for the valve body and is attempting to correlate the MT indications with weld repair areas. This item will be reviewed further during future inspections.
