| Title | Failure to Conduct an Evaluation and Obtain a License |
| Description | The team identified a finding of very low safety significance involving a noncited violation of 10 CFR 50.59, Changes, Tests, and Experiments, for the failure to obtain a license amendment pursuant to 10 CFR 50.90 for changes to the Updated Final Safety Analysis Report. In addition, licensee personnel did not create a written evaluation providing the bases for the determination that the change would not require a license amendment pursuant to paragraph (c)(2) of 10 CFR 50.59. In 2001, licensee personnel changed the Updated Final Safety Analysis Report by replacing allowable emergency diesel generator bus voltage minimums of 85, 81.9, and 80 percent with allowable minimum bus voltages of 75 percent
These changes to the Updated Final Safety Analysis Report result in more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the Updated Final Safety Analysis Report. By being a failure to adhere to a standard (10 CFR 50.59) that was reasonably within the licensee personnels ability to foresee and correct, this issue qualifies as a performance deficiency and a finding. Since the issue has the potential to impact the NRCs ability to perform its regulatory function, this finding must be evaluated under traditional enforcement utilizing the Enforcement Manual with further NRC management review This violation is more than minor because the change would have required NRC approval in accordance 10 CFR 50.59, as discussed previously. Since no changes were implemented in the plant, all systems designed to prevent or mitigate serious safety events were able to perform their intended safety functions. Therefore, since there was no actual loss of safety function, the finding screens as Green in Phase 1 of Manual Chapter 0609, Appendix A. Because this violation is of very low safety significance and has been entered into the licensee's corrective action program as Condition Report 2-05-08086, this violation is being treated as a Severity Level IV noncited violation consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000397/2005009-001, Failure to Conduct an Evaluation and Obtain a License Amendment for FSAR Changes. |
