| Title | Failure to Perform a 10 CFR 50.59 Evaluation for Compensatory Measures Associated with a Procedure Change |
| Description | The inspectors identified a finding having very low safety significance and an associated Severity Level IV, Cited Violation of 10 CFR 50.59 while reviewing unresolved items URI 05000305/2006003-04, Adequacy of Compensatory Actions for Potential Turbine Missile Strike of Control Room Ventilation Cooling; and URI 05000305/2006016-01, Adequacy of 10 CFR 50.59 Screening for Procedure Change. Specifically, the licensee failed to properly interpret design and licensing basis requirements associated with protection against external events and as a result did not perform a 10 CFR 50.59 evaluation. The cause of this finding is related to the cross-cutting area of problem identification and resolution because the licensee had similar prior problems that, if effectively evaluated and resolved, could have prevented this issue. (P.1(c)) This finding was determined to be more than minor because the inspectors determined that the procedure change would have ultimately required NRC approval. The procedure changes, in the form of compensatory operator actions, adversely impacted the operation of control room recirculation system following a tornado. A Phase 1 significance determination of this finding using IMC 0609, Appendix A, \"Significance Determination of Reactor Inspection Findings for At-Power Situations,\" using the Severe Weather Screening Criteria questions was completed. Since the loss of the control room recirculation system would not result in an initiating event or degrade two or more trains of a multi-train safety system, the issue screened as Green.
