O.
STN 50-482/80-11 Appendix A NOTICE OF VIOLATION Based on the results of the NRC inspection conducted on May 27-30, 1980, it appears that certain of your activities were not conducted in full compliance with the conditions of your NRC Construction Permit No. CPPR-147 as indicated below:
Failure to Specify Appropriate Acceptance Criter y 10 CFR Part 50, Appendix B, Criterion V requices that procedures shall include appropriate acceptance criteria for determining that important activities have been satisfactorily accompiished.
Bechtel Specification No. 10466-M-204 specifies in paragraph 5.6.1:
" Welds joining flued heads or closure plates and penetration sleeve shall be considered Class 2 or Class MC welds and shall 1
be full penetration welds. The welds installing thr fuel transfer tube and the stainless steel fuel transfer tube sleeve and the welds joining the weld neck flange to the electrical penetra-tion sleeve shall be made in accordance with NE-4000 and examined j
per NE-5000."
Paragraph NE-4426 of NE-4000 specifies limits for the maximum reinforce-ment of butt welds.
Contrary to the above:
The IE inspector determined that the limits for maximum reinforcement erf butt welds specified in Daniel welding technique sheets N-1-1-BA-1, Revision 4 for welding carbon steel and N.1-8-BA-24, Revision 0 for weld-ing carbon steel to stainless steel and Daniel Quality Control Procedure QCP-VII-200, Revision 5 for visual inspection are less restrictive than required in NE-4000, paragraph NE-4426 of ASME B&PV Code,Section III, 1974 Edition through Summer 1975 Addenda. For example, for a material thickness of one inch, NE-4426 limits the maximum reinforcement to 3/32 inch, whereas, the welding technique sheets and Quality Control procedure permit a maximum reinforcement of 3/16 inch.
This is an infraction.
