| Title | Siphon Line Which Interconnected Two Diesel Generator Emergency Fuel Oil Storage Tanks Was Not Functioning as Designed |
| Description | A finding of very low safety significance (Green) and associated Severity Level IV, Non-Cited Violation of 10 CFR 50.59 was identified by the inspectors while reviewing Unresolved Item 05000305/2008003-03, Siphon Line Which Interconnected Two Diesel Generator Emergency Fuel Oil Storage Tanks Was Not Functioning as Designed. Specifically, while performing Updated Safety Analysis Report change request, UCR 93-031, the licensee inappropriately screened the removal of the Updated Safety Analysis Report reference to the siphon line when plant staff incorrectly answered no to all of the 10 CFR 50.59 evaluation questions. The licensee entered this issue into its corrective action program for evaluation and development of corrective actions, as appropriate. Because violations of 10 CFR 50.59 are considered to be violations that potentially impede or impact the regulatory process, they are dispositioned using the traditional enforcement process. As described in Supplement I of the Enforcement Policy, to determine the severity of a 10 CFR 50.59 violation, the underlying technical issue was evaluated under the Significance Determination Process. The inspectors evaluated the finding using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, Table 4a, for the Mitigating Systems Cornerstone, dated January 10, 2008.The inspectors answered yes to Question 2 in the Mitigation System Cornerstone column which required the issue to be evaluated in accordance with Appendix A, of Inspection Manual Chapter 0609. Using Appendix A, the inspectors screened the issue as very low safety significance (Green) because the quantity of fuel to the diesel generators that was historically available always exceeded that needed for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of operation, thereby, resulting in the probabilistic risk assessment function for the diesels being met. The inspectors determined that the issue had a cross-cutting aspect in problem identification and resolution, corrective action program, because the licensee had identified similar deficiencies with accurately applying or interpreting the current licensing basis, and failed to take timely action to complete corrective actions, or establish barriers to prevent recurrence of this deficiency (P.1(d)) |
