| Title | Failure to Maintain and Report UFSAR Revisions for Safety Analysis and Methodology Chan |
| Description | The inspectors identified a finding of very low safety significance (Green) and associated Severity Level IV (SL IV) non-cited violation of 10 CFR 50.71, Maintenance of records, making of reports. Specifically, 50.71(e) requires that the licensee periodically update the Updated Final Safety Analysis Report (UFSAR), and by letter dated April 12, 2012, the licensee provided the most recent periodic update; however, certain information contained in the update failed to accurately present changes made since the previous submittal and failed to reflect current design and licensing basis. As corrective actions, the licensee has captured the issue in the corrective action program for resolution and plans to review the UFSAR, ensure information is accurately reflected where historical, incorporate the required UFSAR content, and make necessary changes to enhance oversight of future UFSAR revisions. Consistent with the guidance in Inspection Manual Chapter 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated September 7, 2012, because the issue had the potential to affect the NRC's ability to perform its regulatory function, the violation was reviewed under the traditional enforcement process. Consistent with the guidance in Section 6.9, Paragraph d.9, of the NRC Enforcement Policy, the violation associated with this finding was determined to be a SL-IV violation. Additionally, the significance of the underlying technical issue (i.e., failure to reflect the current licensing basis in the UFSAR, failure to remove obsolete methodology for determining design and operating limits; and, failure to supervise how individuals control and modify information presented in LaSalles UFSAR) was evaluated using the Significance Determination Process (SDP). The finding was determined to be more than minor because, if left uncorrected, it could lead to a more significant safety concern. Specifically, methodologies could be utilized without properly performing 50.59 reviews, leading to revisions to operating ranges, such as those found in the power-to-flow map, which may not have been reflected in the subsequent safety analyses, the failure to update also reduced the ability of the licensee and the NRC to review the stations licensing basis to assess design changes or assess facility safety. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings At Power, Exhibit 3, dated June 19, 2012. The inspectors reviewed the Barrier Integrity Screening Questions in Appendix A, Exhibit 3 and answered No to all the questions, which screens the issue as Green. The finding had a cross-cutting aspect in the area of Human Performance, Work Practices, because the licensee failed to supervise and manage the oversight of UFSAR changes with LaSalle station staff, corporate nuclear fuels, and contractor |
