APPENDIX A t
NOTICE OF VIOLATION Duke Power Company License No. CPPR-84 McGuire Based on the NRC inspection January 9-11, 1980, certain of your activities were apparently not conducted in full compliance with NRC requirements as indicated below. These items have been categorized as described in correspondence to you dated December 31, 1974.
A.
As required by Paragraph (a)(1) of 10 CFR 50.55a, " Structures, systems, and components shall be designed, fabricated and inspected to quality standards commensurate with the function to be performed." For reactor coolant pressure boundary and other safety related piping this quality standard is identified in the FSAR as ASME Section III. ASME Section III provides minimum weld size requirements for socket welds flanges in Figure NB-4427-1.
Contrary to the above, on January 10, 1980, the licensee's weld process control sheet for ASME Section III Class I socket-welding flange welds NC2FW83-20 and -21 in the Reactor Coolant System specified minimum weld sizes below that required by ASME Section III.
In addition, the following welds had sizes below the minimum requirements:
Weld System Pipe Size Code Class NV2FW274-6 Chemical Volume Control 2" Sch 160 2
NV2FW274-10 Chemical Volume Control 2" Sch 160 2
NC2FWFT5070-1 Reactor Coolant 3/4" Sch 160 2
NC2FWFT5060-4 Reactor Coolant 3/4" Sch 160 2
NC2FW43-7 Reactor Coolant 1" Sch 160 1
This is in infraction.
B.
As required by Criterion V of Appendix B to 10 CFR 50, and implemented by DPC Topical Report Duke 1-A Section 17, Paragraph 17.1.5, " Activities affecting quality shall be accomplished in accordance with the requirements imposed by... instructions, procedures and drawings." Procedure F9 Rev. 7 requires that craftsmen responsible for work maintain design drawings at 1
the work location.
L Con..rary to the above, on January 10, 1980, a Safety Injection System piping subassembly that includcJ weld NI2FW54-21 did not comply with design drawing dimensional requirements and the design was not present at the work station.
This is an infraction.

As required by Criterion V of Appendix B to 10 CFR 50, and as implemented by DPC Topical Report Duke 1-A Section 17, Paragraph 17.1.5, " Activities affecting quality shall be accomplished in accordance with the requirements imposed by... Instructions, procedures, and drawings. Procedure M4 Rev. 5 requires final visual inspection of welds in accordance with procedure L80 (Rev. 7).
Contrary to the above, on Janaury 10, 1980, the inspector performing final visual inspection on weld NI2FW54-21 did not know how to perform the inspec-tion required to assure compliance with final weld offset requirements stated in procedure L80 (Rev. 7).
