| Title | Failure to Have an Adequate Procedure for Vendor Information |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated with the licensees failure to have an adequate procedure for controlling and processing vendor documents and vendor technical manual updates. This resulted in the licensees failure to properly implement new torque requirements for the turbine driven auxiliary feedwater pump trunnion bolts, and their subsequent backing out. The licensee performed an operability determination for the loose trunnion bolts that established a reasonable expectation for operability. The licensee entered the finding into the corrective action program as Condition Report CR-2014-009518. The failure to have an adequate procedure for controlling and processing vendor documents and vendor technical manual updates was a performance deficiency. The performance deficiency was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the inadequate procedure allowed a lower torque value to be used on the trunnion bolts for the Unit 2 turbine driven auxiliary feedwater pump which resulted in a condition where the trunnion bolts were loose. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, dated June 19, 2012, the finding was determined to be of very low safety significance (Green) because the finding: (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality, (2) did not represent a loss of system and/or function, (3) did not represent an actual loss of function of at least a single train for longer than its allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time, and (4) does not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in accordance with the licensees maintenance rule program. The inspectors determined that this finding does not have a cross-cutting aspect because the most significant contributor of this finding occurred more than three years ago and does not reflect current licensee performance. |
