| Title | Failure to Follow Procedure for the Control of Tools for Use on Stainless Steel |
| Description | Inspectors identified a non-cited violation of very low safety significance of Technical Specification 6.8.1.a and Regulatory Guide 1.33, for the failure to follow procedures that ensured abrasive tools for use on stainless steel systems were not contaminated with carbon steel. Specifically, the inspectors determined that the licensee was not maintaining tools as required by Procedure 0PGP03-ZG-0001, Control of Materials and Products By User Groups, Revision 30, and Procedure 0PNP01-ZP-0032, Tools and Measuring &Test Equipment Control, Revision 6, because inspectors observed multiple instances of tools coded for use on stainless steel or aluminum bronze stored with tools marked for use on carbon steel, rust deposits on tools marked for use on stainless steel, and rust deposits on stainless steel components in the plant. This indicated that carbon steel contaminated tools may have been used on these systems. The licensee took corrective actions to segregate the coded tools and trained tool room attendants to properly store and mark abrasive tools designated for use on stainless steel, and evaluated the systems with indications of rust deposits. This issue was entered into the licensees corrective action program as Condition Report 12-28689. Inspectors determined the failure to assure that abrasive tools designated for exclusive use on stainless steel were stored separately from tools used on other materials was a performance deficiency. This finding was more than minor because it affected the Initiating Events Cornerstone attribute of Equipment Reliability and affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions. Using Manual Chapter 0609, Attachment A, The Significant Determination Process (SDP) for Findings At-Power, the finding was determined to be of very low safety significance (Green) because the finding did not result in exceeding the reactor coolant system leak rate for a small loss-of-coolant accident, and did not affect other systems used to mitigate a loss-of-coolant accident resulting in a total loss of their function. This finding had a cross-cutting aspect in the area of human performance work practices in that the licensee failed to effectively communicate expectations regarding procedural compliance, and personnel did not follow procedures. Specifically, the inspectors observed that although there were requirements to segregate tools, tools were not consistently segregated when returned to the storage locations as required by procedures |
