| Title | Inadequate 10 CFR 50.59 Safety Evaluation for UFSAR Change RN 96-72 |
| Description | The licensees 10 CFR 50.59 safety evaluation performed to incorporate the results of the Transient Stability Study of the Offsite Power System into the Updated Final Safety Analysis Report (UFSAR) Section 8.2.2.2 did not provide an adequate technical basis to support the determination that an unreviewed safety question did not exist. Specifically, the 10 CFR 50.59 did not address the increase in the probability of occurrence of a malfunction of the loss of voltage relay for Case Study Six of the Transient Stability Study; and it did not provide an adequate technical basis to support the conclusion in the UFSAR that the requirements of 10 CFR 50, Appendix A, General Design Criterion 17 would still be met for the grid conditions evaluated for Case Study Six. A non-cited violation was identified. |
