Condition Reporte As required by paragraph (a)(1) of 10 CFR 50.55a, Structures,...shall be...constructed,
- tested, and inspected to quality standards commensurate with the importance of the safety function....
For the containment structure, this requirement is implemented by paragraph 5.5.1.2 of the PSAR which requires that containment welding be accomplished in accordance with Article CC-4000 of Section III Division 2 of the ASME Code.
Paragraph CC-4541.2 of the applicable addenda of CC-4000 states that "...surfaces for welding shall be free of scale, rust,...".
Contrary to the above, on May 15, 1980, the tack welds, attaching the base plate of containment spray piping restraint CT-H-117 to the respective containment
- pad, wer e deposited over heavy rust.
Corrective Steps Taken and Results Achieved:
The nonconforming condition listed in the Notice of Violation was reported in Deficiency and Disposition Report Number 411 for purpose of control and resolution.
The deficient tack welds attaching the pipe restraint to the pad at azimuth 242 -49'-49'n Ol Containment dome were removed, the surface was prepared as required and new tack welds were made attaching the restraint to the pad.
The Contr actor performed a re-inspection of previous pad to liner tack welds to rectify similar deficiencies.
No other such cases were found.
Corrective Steps Taken to Avoid Further Noncompliance:
The Contractor held a meeting with all welders, fitters, tackers and pushers to emphasize that surface preparation requirements for tack welds are the same as for final welds.
Surfaces to be tack welded are now being wire brushed prior to welding.
Implementation of this welding procedure requirement will be reviewed more frequently by the Contractor's Melding OA Supervisor and Welding and QA Superintendent.
Date When Full Compliance Mill be Achieved:
Full compliance was achieved June 17, 1980.
