SUBJECT:
Waterford SES Unit 3 IE Inspection Report 382/80-07
Dear Mr. Seyfrit:
The following information regarding the infraction cited by the USNRC Inspectors against Industrial Engineering Works in USNRC Docket No.
50-382/ Report 80-07 dated May 28, 1980, is herewith submitted.
General Comments LP&L has been implementing corrective actions concerning the Industrie, Engineering Works manufactured material since architect-engineer, Ebe Services, Inc., discovered the initial deficiencies associated with the restraints.
This discovery occurred prior to the allegation concerning the IEW supplied material. LP&L reported the deficiencies in full com-pliance with Nuclear Regulatory Commission regulations in Interim Report of Construction Deficiency No. 15 dated January 2, 1980.
The Ultrasonic Testing (UT) examinations which were being performed by the alleger were being conducted as a result of corrective actions associated with Construction Deficiency Report No. 15.
According to your report, the alleger stated that he pointed out the specific defects of visible non.asion, weld undercut, porosity, weld overlap and areas where welds were incomplete to an IEW representative, but apparently nothing was eve: donc about them. We disagree with this allegation. The information available to evidence that these contitions were reported by the alleger are the UT reports appended to Nonconformance Report W3-1802-011.
These reports are annotated with the comment (s)..... " Weld does not meet vis-ual qualifications for full penetration welds."
Your report states that all of the conditions mentioned in the allegation were visible to varying degrees on piece 1-DlA-Bil-E6-Wl-2.
Our review cf this matter indicates that, there was a small area of non-fusien or incomplete weld at each end of the seven (7) inch welds on the D-Stop.
All other conditions were within specification and code requirements.

Mr. f.'V. S yfrit Infraction:
i Failure to Verify Conformance With Documented Drawings 1)
Corrective steps which will be taken and the results achieved.
This item of noncompliance is documented on nonconformance report W3-1992 and has been dispositioned to have the eight "D" stops returned to Industrial Engineering Works (IEW) for repair or replacement.
~
The repair of the "D" stops will be accomplished by grinding the weld def:ects to sound metal, and these surfaces visually inspected by IEW and Ebasco personnel. These areas will then be rewelded using approved i
weld procedures and qualified welders with subsequent inspection of the completed welds again performed by IEW and Ebasco. The weld repaired i
areas will be magnetic particle examined, post veld heat treated, and I
magnetic particle examined again. The total postweld heat treatment time accumulated will be checked to assure that production material and weldicg procedure test times have not been exceeded. The "D" stops will then be blasted, painted and subsequent final inspection performed by Ebasco.
The "D" stop pieces welded 900 out of position from that indicated on the assembly drawing will be reworked as necessary to comply with the j
latest approved revision of the assembly drawing.
- 2) The steps taken to preclude recurrence.
3 IEW management personnel have provided reinstruction to inspectors on the requirements of-inspection procedures and has implemented additional weld instruction and inspection criteria.
IEW managemen will direct more attention to the inspection and supervision of all fabricated material.
- 3) The date when full compliance will be achieved.
Full compliance will be achieved when all repairs are completed and
)
when Ebasco's final inspection has been performed. The date on which this will be completed is July 22, 1980.
The results of the completed repairs and final inspection will be included in the Significant Construction Deficiency Report No.15 due to the USNRC July 31,-1980.
Yours very truly, D. L. Aswell DLA/LLB/grf I
