- WV Docket No. 50-508 G.
August 23, 1982 G03-82-838 U. S. Nuclear Regulatory Commission, Region V Office of Inspection and Enforcement 1450 Maria Lane, Suite 260 Walnut Creek, California 94596-5368 Attention: Mr. D. M. Sternberg Chief, React.or Projects Branch No. 1
Subject:
NRC INSPECTION AT WNP-3 IE REPORT NO. 50-508/82-04 VIOLATION A (NONCOMPLIANCE 50-508/82-04/01)
Reference:
Letter G03-82-524, dated May 21, 1982, R. S. Leddick to T. W. Bishop, same subject.
The referenced letter provided your office with a partial response for the subject violation (failure to fabricate and install CB&I Containment Dome Inspection Platform and Ladders in accordance with the specified qual-ity program). The letter noted that a complete response would be submitted after the detailed analysis and investigation, required to determine the scope of the problem and resultant corrective actions, was completed.
To date, the seismic analysis of certain identified Class D items has not been completed by Ebasco. Also, CB&I is still in the process of inspection and repair of deficient welds.
Until the full scope of the problem can be determined, a date of full com-pliance cannot be established. Therefore, the following status of correc-tive actions taken and planned is provided pending issuance of a final re-port.
1.
Attachment I is a listing of the items specified or furnished as CBI Class D.
Ebasco has reviewed the list and has segregated it into "A" and "B" items.
(a) For "A" items, Ebasco rill perform a seismic analysis of the following: That portion of Item A2 that includes the construc-tion hatch outside platform at Elevation 432.00, Item A3 and Item A10. CB&I is to perform the seismic analysis for the remaining "A" items. CB&I has started its evaluation with satisfactory results to date.
It is anticipated that Ebasco will be completed by September 30, 1982.
(b) For "B" items, Ebasco has determined that seismic analysis and additional inspections are not required because their failure would not affect safe shutdown of the plant.

Mr. D. M. Sternberg Page 2 August 23, 1982 G03-82-838 2.
Material Verification will be accomplished as follows:
(a)
Items A2 and A3 are presently being fabricated. CMTRs are avail-able for these items (excluding grating, handrails and bolting less than one inch diameter). CB&I is required to fabricate, install and document these items in accordance with the require-ments of Quality Class I.
(b) For all other items on Attachment I, CB&I will provide a C of C to the material specification listed on the CB&I drawing.
3.
Ebasco will assure inspection of all "A" items on Attachment I, except Items A2 and A3 which will be per Item 2(a) above. The inspection shall be as follows:
(a) All accessible welds joining the CB&I Class D materials (i.e.
Quality Class G) are to be visually examined (VT) to the require-ments outlined in the original NCR that documented the deficiency.
Items that have been painted shall be inspected without removing the paint. Questionable areas shall be stripped if painted, re-inspected, repaired as necessary and repainted to the CB&I Class D (i.e. Quality Class G) requirements. VT reports shall be pre-pared for each assembly, as detailed on the CBI drawings, to document the results of the inspection.
(b) Approximately 10% of the high strength bolts (A325, A490, A449) used in the installation of the Class D material of Attachment I, shall be torque checked, using a calibrated torque wrench, to the requirements of AISC 7th edition, Table 1.23.5.
If inadequately torqued bolts are found in the 10% sample, they shall be correctly torqued and a second set of 10% shall be checked.
If additional unsatisfactory bolts are found in the second 10%
set, all bolts shall be retorqued. The inspection results shall be documented.
(c) Approximately 5% of all other bolts used in the installation shall be wrench checked as snug tight.
If loose bolts are found, all the bolts in that connection shall be checked prior to resum-ing the 5% inspection. The inspection results shall be documented.
4.
Ebasco will revise the FEAR to reflect the QC Class G status of items in accordance with the disposition of the original NCR that documented the deficiency.
Mr. D. M. Sternbe-Page 3 August 23, 1982 G03-82-838 5.
CBI is in the process of repairing welds found to be deficient. Esti-mated date of completion is August 31, 1982.
6.
Ebasco is presently reviewing the program for contract review and approval to determine the cause of the incorrect quality classifica-tions. Results of this investigation will be provided in the final report of corrective / preventive actions.
A final report of the corrective / preventive actions taken and a date of full compliance will be forwarded to your office by November 19, 1982.
Should you have any questions or desire further information, please con-tact me directly.
