| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings
requires, in part, that Activities affecting quality shall be prescribed by documente instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, on May 20, 2014, a welder failed to follow procedures/instructions and used the shielded metal arc welding (SMAW) process to weld the steam generator secondary side internal access hatch instead of the specified gas tungsten arc welding (GTAW) process that was specified in Work Order WO-ANO-00366662. The individuals involved failed to follow the instructions and requirements of multiple procedures and documents. Procedures and instructions not followed included Procedures CEP-WP-004, Control and Documentation of Welding Activities, and CEP-WP-005, Control and Issue of Weld Material, and Work Orders WO-ANO-0366661 and WO-ANO- 0366662. In addition, although the material issue control document specified that filler material ER70S-2, which is for GTAW be used, the welder requested and was issued filler material E7018, which is for use in SMAW. Procedure EN-HU-102, Human Performance Traps & Tools, Revision 13, Attachment 9.5, requires both the briefer and the individual tasked to perform the work to verify that the individual assigned to complete the task is qualified to perform the task and has curren qualifications. However, the welder assigned to perform the welding on the steam generator secondary side internal access hatch was not qualified in GTAW; although, he was qualified in SMAW. Per ASME Code, SMAW is an acceptable process for welding of the steam generator secondary side internal access hatch, even though not specified by the procedure. The inspectors determined that the weld process used was acceptable per ASME Code, was performed by a welder qualified in the process that was used, and the final weld passed the required non-destructive examination acceptance criteria. The finding is more than minor because if left uncorrected the finding could have become more significant, in that assigning unqualified personnel to perform quality controlled evolutions could be a precursor to a significant event if undetected performance deficiencies develop. Using NRC Manual Chapter 0609, Significance Determination Process, Phase 1 worksheets, the inspectors determined the non-cited violation had very low safety significance. The licensee entered this issue into their corrective action program as Condition Report CR-ANO-2-2014-01424. |
