| Title | Failure to Evaluate the Adverse Effects of Sharing the RWSTs of Both Reactor Units |
| Description | During an U.S. Nuclear Regulatory Commission (NRC) inspection conducted from April 20, 2015, through May 22, 2015, a violation of NRC requirements was identified. In accordance with the NRC Enforcement Policy, the violation is listed below: Title 10, Code of Federal Regulations (CFR), Part 50, Appendix B, Criterion XVI, Corrective Action, states, in part, that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and non-conformances are promptly identified and corrected. Contrary to the above, from June 15, 2012, to May 22, 2015, the licensee failed to correct a condition adverse to quality (CAQ). Specifically, on June 15, 2012, the NRC issued a Non-Cited Violation 05000454/2012007-05; 05000455/2012007-05 for the failure to provide means to detect and isolate a leak in the emergency core cooling system within 30 minutes for Byron Station, Units 1 and 2, as described in Section 6.3.2.5 of the Updated Final Safety Analysis Report which is a CAQ. As of May 22, 2015, the licensee had not corrected the CAQ in a reasonable time period. Instead, the licensee created action tracking items to develop a plan to correct the CAQ, and the associated due date was extended at least eight times. This violation is associated with a Green Significance Determination Process finding. |
