Appendix A NOTICE OF VIOLATIO'l Based on results of the NRC inspection conducted on March 21-24, 1978, it appears that certain of your activities were not conducted in full compliance with Appendix B to 10 CFR 50 as indicated below:
Failure to Follow Pipe Fabrication Procedures Criterion V of Appendix B requires that established instructions, pro-cedures or drawings be followed for all activities affecting quality.
j Brown & Root Construction procedure 35-1195-MCP-7, " Machining and Weld Finish," requires that transitions between a pipe inside diameter counterbore and the original inside diameter be a slope not greater than 30* to the plane of the pipe wall.

The inspector observed on March 23, 1978, a number of pipe sections and one accepted weld joint (CS-1-RB-24-Q2-W2) with counterbore transition slopes greater than 30 to the plane of the pipe wall.
This is an infraction.
