L. E. Tripp, Chief, Engineering Support date Section No. 1 Inspection Summary:
Unit 1 Inspection on September 12-14, 1979 (Report No. 50-334/79-04)
Areas Insoected:
Routine unannounced inspection by a Regional based inspector of work activities and records associated with receipt, installation and welding of safety related piping.
The inspection involved 20 inspector-hours on site by one Regional based inspector.
Results:
Of the three areas, no item: of noncompliance were identified in two areas; one item of apparent noncompliance was identified in one area.
Failure to follow applicable Code requirements relative to repair welding.

2.
Plant Tour A tour at the site was made to observe the status of the work ano construction activities in progress.
The inspector examined itens for any obvious defects or noncompliances with regulatory requirements or license conditions.
Areas / activities observed included: structu'al welding within containment, equipment stored in place, pipe lay-Jown areas and warehouse storage of pipe spools.

3.
Safety Related Piping - Special Welding Applications The inspector audited randomly selected document packages associated with vendor supplied pipe spool assemblies.
The audit was to verify compliance with specification and applicable Code requirements.
These safety related pipe spools were supplied as shop fabricated items by Dravo under P0 10855-P-201(Q), and were shop inspected and released by the constructors shop inspector.
Also, these pipe spools had been received at the site and installed by the constructor.
Specific pipe spools and welds are identified as follows:
1-BC-088-S05-Weld G
--
1-BC-088-S12-Weld C
--
1-BC-066-S03-Weld D
--
The above pipe spools evidenced a weld deposit (build-up) on the outside surface of the component adjacent to the above girth welds.
Vendor data did not show the reason (s) for the unspecified weld build-up.
Nor did these data document the performance of surface examination.
Discussions with cognizant personnel disclosed that in some instances counterboring of the components may have violated the specified wall thickness requirements, thereby necessitating the weld build-up to re-establish the required wall thickness.
The applicable Code, ASME Section III, 1974 Edition, Article NC-4000, paragraph NC-4214, " Minimum Thickness of Fabricated Materials" stip-ulates repair and examination requirements for materials reduced below their minimum required thickness during fabrication processes.
It also specifies that surface examination be parformed on all repair welding in this category.
This item is a violation of 10CFR, App?ndix B, Criterion VII.
4.
Safety Related Piping-Record Review The inspector examined ducumentation packages for four safety related field welds, 1-BC-044-Sil-FW-7, 1-BC-088-503-FW-3, 1-BC-088-515-FW-14 and 1-BC-088-505-FW-2.
The record review was performed to determine whether the e records met established procedures and whether records reflect work accomplished is consistent with applicable Code require-ments in the following areas:
Fit-up inspection.
--
Weld history records document that work was accomplished in
--
accordance with applicable procedural requirements.
1794 510
.
.
Temperature controls as required.
--
Post weld inspection.
--
No noncompliances witti regulatory requirements were identified.
5.
Visual Examination of Safety Related Piping Welds The inspector performed a visual examination of safety related welds to determine whether the following characteristics conform to the ASME Section III Code and the contractors procedural requirements.
Weld surface finish and appearance.
--
Weld reinforcement height and transition area.
--
Removal of temporary attachments.
--
Surface appearance of welds.
--
Specific welds examined were identified in the following pipe spools:
1-BC-088-503,
--
- 1-BC-088-504,
--
- l-BC-088-505,
--
1-BC-088-S.
--
PS-1-A3,
--
MS-PS-1-A2,
-
--
MS-PS-2-B3, and,
--
MA-1-45 Containment stray header support.
--
The areas adjacent the above asterisked welds exhibited considerable surface grinding.
Discussions with contractor personnel disclosed that a wall thickness verification technique / program was being de-veloped to verify that minimum wall thickness requirements had been maintained. The inspector had no further questions regarding this item at this time.
