RESPONSE TO ENFORCEMENT ITEMS Below in our response to Appendix A, Notice of Violation, of United States Nuclear Regulatory Commission I.E. Report 50-440/82-03; 50-441/82-03:
I.
Noncompliance 440/82-03-03 A.
Severity Level V Violation 10CFR50, Appendix B, Criterion IX states in part that, " Measures shall be established to assure that special processes, including...
nondestructive testing, are controlled and accomplished by qualified personnel using qualified procedures in accordance with applicable codes, standards, specifications, criteria, and other special requirements."
The Ferry Nuclear Power Plant, Units 1 and 2, PSAR Section 17.1.9.2, states in part that "CEI requires contractors to establish and document measures that will assure that special processes will be accomplished...in accordance with the applicable codec..."
The specified code, American Society of Mechanical Engineers (ASME)
Boiler and Pressure Vessel Code,Section V 1974 Edition, Summer 1975 Addenda, paragraph T-235.2 requires that the location markers locate the area of interest accurately and ASME Section III, 1974 Edition, Summer 1975 Addenda, paragraph NE-5321 states that incomplete fusion, excessive elongated indications (slag) and cracks are unacceptable.
Contrary to the above, lead location markers were in the area of interest, a repair area was not correctly identified by location markers, and lack of fusion, excessive slag and a crack were found in various welds.
B.
Response
Condition 1 - Assembly #0M-61-21X Weld B, area P-S-B was re-radio-graphed with the location markers placed in the correct locations, outside the area of interest, re-evaluated and found acceptable. No further action required.
Condition 2 - All radiographs of welds associated with NRs # 17-152,17-777, 17-195,17-254 and 17-268 has been re-reviewed by CEI NDE Element 100%. This second review consisted of 58 weld joints of which 36 were rejected. Based on this reject level, we are evaluating this problem for reportability pursuant to 10CFR50.55(e).
Because of the high reject rate of those containment welds identified above, the NDE element has committed to, and is in the process of per-forming a 100% re-review of all welds of Units I and II containments.
d RESPC1"E TO ENFORCEMENT ITEMS Page Two To date, 874 films have been re-reviewed representing 5% of the total for both containments.
Projected completion date for this rev'aw is August 31, 1982.
