Docket No. 50-445 Docket No. 50-446 Appendix A NOTICE OF VIOLATION Based o'n results of NRC inspections on August 21-25, 1978, it appears that certain of your activities were not conducted in full compliance with Appendix B to 10 CFR 50 as indicated below:
1.
Failure to Follow Welding Procedures Criterion V of Appendix B requires that established instructions,.
procedures, or drawings be followed for all activities affecting quality.
Brown and Root Weld Procedure 88025 Revision 0, requires that welders weld such that a minimum of two inches of weld bead be deposited each minute.
Contrary to the above:
The inspector observed on August 23, 1978, that two welders depositing weld bead in weld joint'FW-16, of the Reactor Coolant piping, as identified on drawing RC-1-520-1, were welding such as to deposit bead at a rate of 1.1 and 1.9 inches per minute.
This item of noncompliance is an infraction.
2.
Failure to Follow Weld Monitoring Procedures Criterion V of Appendix B requires that established instructions,
~
procedures, or drawings be followed for all activities affecting quality.
Brown and Root document 35-1195-WCP-3 Revision 8, dated November 7, 1977, titled " Administration and Organization of Field Welding Technical Center," requires in paragraph 4.3 that each welder be monitored, as a minimum, every ten working days and the results recorded on " parameter logs."
Contrary to the above:
The inspector observed during a review of the parameter logs that three welders identified as welding on the reactor coolant system had been monitored last on June 20,1978; June 26,1978, and December 6,1977, respectively. This matter has been discussed with licensee representatives who have confirmed that the facts outlined are essentially correct.
This item of noncompliance is an infraction.
3.
Failure to Adequately Control and Tag Nonconforming Items 10 CFR Part 50, Appendix B, Criterion XV, requires that measures be established to prevent inadvertent use or installation of nonconforming items which include identification and segregation.
Brown and Root Procedure QAP-15.1, Section 5.1.1 requires that nonconforming items be tagged, segregated and/or marked.
Contrary to the above:
Although measures have been established for identification and segregation of items which are nonconforming, the IE inspector found, at 9:30 a.m., on August 25, 1978, that nonconforming cable tray supports were not adequately tagged and' segregated.
The inspector specifically found:
- 1) the barrier separating nonconforming cable tray supports from acceptable supports was broken and fallen to the ground;
- 2) the nonconformance tag, No. E-1105, was attached to the barrier tape which had fallen to the ground and was obscured by dust; 3) the individual nonconforming items were not marked as to their status; and 4) the Nonconformance Report, NCR E-1105, did not identify by item number or count the nonconforming cable tray supports.
This item of noncompliance is an infraction.
