| Title | Maximum Differential Temperature Exceeded for Spray Nozzle during Pressurizer Heatup |
| Description | A self-revealing non-cited violation (NCV) of TS 5.4.1, Procedures, was identified in that the shift technical advisor's (STA) failure to follow procedure resulted in the maximum differential temperature being exceed on the spray nozzle during pressurizer heat up. Specifically, the STA failed to notify the shift manager promptly when it became apparent that the maximum differential temperature of the spray nozzle trend was degrading and its limit subsequently exceeded. This issue was entered into the licensee's corrective action program under CR 10-85021. Traditional enforcement does not apply because the issue did not have an actual safety consequence or the potential for impacting NRC's regulatory function, and was not the result of any willful violation of NRC requirements. The inspectors determined that the finding was not similar to the examples for minor deficiencies contained in IMC 0612, Appendix E. Examples of Minor Issues. The finding was more than minor because if left uncorrected, had the potential to lead to a more significant safety concern. The inspectors performed a Phase 1 SOP evaluation in accordance with IMC 0609, Appendix G, Attachment 1, Checklist 4 PWR Refueling Operation: RCS level> 23' or PWR Shutdown Operation with Time to Boil> 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> And Inventory in the Pressurizer. There was no loss of control. aU mitigating capabilities were available, therefore a Phase 2 quantitative assessment was not required and the issue screened to Green (very low safety significance). The cause of this NCV relates to the cross-cutting aspect of Human Performance, Resources, in that FENOC personnel were not adequately trained to recognize the indications being monitored, resulting in the pressurizer spray nozzle maximum differential temperature being exceeded. |
