APPENDIX A NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-413 & 50-414 Catawba 1 and 2.
License Nos. CPPR-116 & CPPR-117 As a result of the inspection conducted on March 17-20, 1981, and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7,1980), the following violations were identified.
A.
10 CFR 50,. Appendix B, Criterion IX as implemented by Du' e Power Company e
(DPC) Topical Report " DUKE 1-A" Section 17, Paragraph 17.1.9 requires measures be established to assure that special processes, including welding are controlled. Duke's welding program is controlled by QAPP L-100, " Weld-ing Program". ASME B and PV Code Section IX with Interpretation IX-78-92 of. September 25, 1978, has been identified as the applicable code for welder qualification. Interpretation IX-78-92 limits the welder qualifica-tion thickness range qualified to lis inch maximum for combination process welder qualification tests administered on 3/4 inch pipe test assemblies.
QAPP M-4, " Visual Inspection and NDE of Welds (ASME III)" controls preweld visual inspection of repati welds. CNS-1121.001-1 " Specification for Field Fabrication of Structural Steel Construction for Nuclear Safety Related Structures", has been identified as the applicable fabrication specifica-tion for the fabrication of the containment spray system heat exchanger supports.
Contrary to the above, on March 17-19, 1981, adequate measures were not established to ' assure that special processes including welding were controlled in that the following examples were noted:
1.
The traveler for - Weld No. 2ND-66-20 which has a "J" bevel weld
. preparation authorized the use of a weldig procedure (L-234), which is applicable to a "V" bevel weld prepare, ion only.
2.
Performance Qualification Field Weld Data Sheet L-180, a combination l
process test adminiitered on a 3/4" wall thickness groove pipe test
. assembly, incorrectly states that the tested walder is qualified for j
unlimited thickness.
l l
3.
Weldir.g inspectors are performing preweld visual inspection of repair cavities to QAPP M-4 which does not have defined acceptance criteria.
4.
Welding inspectors are making the determination of whether to back purge repair welds to QAPP M-4 which does not have defined acceptance criteria.
l 5.
Drawing CN-1220-43 Revision 11 for the containment spray system heat l
exchanger support specifies CNS-1120-00-1, "230 KV Switching Station l
Low Structures - Structural Steel" as the applicable fabrication l
specification.

Process Sepcification L-300, Shielded Metal Arc Welding",
Revision 10, paragraph 9.2 limits the maximum bead width to 3/4 inch maximum for non-cover fill beads deposited with 1/8 inch diameter electrodes.
Contrary to the above, on March 17, 1981, activities affecting quality were not accomplished in accordance with documented procedures in that the welder of record for safety injection system weld joint no. 2-NI-15-1 (Repair) deposited 1 1/8 inch wide, non-cover, fill, beads for 25% of the circum-ference of the joint with a 1/8 inch diameter electrode.
This is a Severity Level V Violation (Supplement II.E).
This applies to Unit 2 only.
Pursuant to the provisions of 10 CFR 2.201, you are hereby required to submit to this office within twenty-five days of the date of this Notice, a written state-ment or explanation in reply, including: (1) admission or denial of the alleged violations; (2) the reasons for the violations if admitted; (3) the corrective steps which have been taken and the results achieved; (4) corrective steps which will be taken to avoid further violations; and (5) the date when full compliance will be achieved. Under the authority of Section 182 of the Atomic Energy Act of 1954, as amended, this response shall be submitted under oath or affirmation.
