| Title | Failure to Update the Updated Safety Analysis Report - Combustible Gas Control System Supply Fan Motor 1VR08C Function |
| Description | The inspectors identified a Severity Level IV non-citied violation of 10 CFR 50.71(e), Periodic Update of the Updated Safety Analysis Report (USAR), and an associated Green finding for the licensees failure to update the USAR with the correct description of the function of the combustible gas control system supply fan motor, 1VR08C. Specifically the licensee did not update Section 9.4.5.5 of the USAR to include the correct function of 1VR08C as described in a commitment made to the NRC in the licensees letter U600850. Consequently the licensee performed a 10 CFR 50.59 evaluation for abandoning a portion of the system that did not consider the correct function of the component. The licensee entered this issue into thei
corrective action program as AR 1692665, removed 1VR08C from the modification plan and is updating the USAR with the correct function for this component. The inspectors determined that the failure to update the USAR with the correct function of 1VR08C was a performance deficiency. The performance deficiency was determined to be more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated September 7, 2012, because, if left uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern and is therefore a finding. Specifically, failure to update the USAR with the correct safety related function of 1VR08C could result in the licensee making operability and functionality determinations based on incorrect assumptions. Additionally, the failure to update the USAR with the correct function of the fan was more than minor because it was associated with the Barrier Integrity cornerstone attribute of design control, plant modifications and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The finding was screened against the Barrier Integrity cornerstone and determined to be of very low safety significanc because the finding does not represent an actual open pathway in the physical integrity of reactor containment, containment isolation system, and heat removal components and it did not involve an actual reduction in function of hydrogen igniters in reactor containment. The performance deficiency associated with this finding did not reflect current licensee performance; therefore, no cross cutting aspect was identified with this finding. Additionally, in accordance with Section 6.1.d.3 of the NRC Enforcement Policy, this violation was categorized as Severity Level IV because the licensees failure to update the USAR as required by 10 CFR 50.71(e) had not yet resulted in any unacceptable change to the facility or procedures.
