| Title | Failure to Adequately Implement Procedure Requirements for Refueling Machine Operation |
| Description | A self-revealing non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, was identified for the failure of refueling services personnel to follow procedures to address refueling machine fault indications. Specifically, during the Unit 1 refueling outage core offload, refueling services personnel had overridden interlocks that protect the fuel from damage. This issue has been entered into the licensees corrective action program as Palo Verde Action Request 3235153 and Condition Report Disposition Request 3237465.The finding is greater than minor because it is associated with the human performance attribute of the barrier integrity cornerstone and affects the cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. Manual Chapter 0609, Appendix M, Significance Determination Process Using Qualitative Criteria, was used since the Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process, does not address the potential risk significance of refueling machine operation errors. The finding is determined to have very low safety significance because there was no apparent damage done to the fuel barrier and no radioactive release occurred. This finding has a crosscutting aspect in the area of human performance associated with decision making because refueling services personnel did not use a systematic process to make a risk significant decision when faced with uncertain or unexpected plant conditions H.1(a) (Section 1R20) |
