Based on the results of NRC inspections conducted during the period of 1
January 1-31, 1980, it appears that certain of your activities were not conducted in full compliance with conditions of your NRC Construction Permit No. CPPR-134 as indicated below:

10 CFR 50, Appendix B, Criterion V, states, in part, that " Activities affecting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances...."
WPPSS Contract Specifications 211 and 257 for the installation of piping specifies that attachments to structural steel shall be done in accordaisce with the AWS Structural Welding Code D.l.1-1974.
i Part 8.14 of this code requires that temporary welds shall be subject to the same welding procedure requirements as final welds.
Also, part 3.2 of this code requires cleaning of foreign material from surfaces to be welded.
Contrary to the above requirements, as of January 28,1980, no documented instructions, procedures or drawings were provided to control the installation and removal of temporary attachment welds to structural steel of the Unit 1 general services building, a safety-related structure. Temporary attachments were welded to this structural steel without cleaning paint from the areas to be welded.
This is an infraction.
