ould be small and consistent with the intent of the Commission's Safety Goal Policy Statement [Sections 111.2.2 and 111.2.31. 5. The impact of the proposed change should be monitored using performance measurement strategies [Section 111.31. In demonstrating adherence to the above principles, reviewers should ensure that licensees address the following issues as part of their submittals: All safety impacts of the proposed change are evaluated in an integrated manner as part of an overall risk management approach in which the licensee is using risk analysis to improve operational and engineering decisions broadly by identifying and taking advantage of opportunities to reduce risk, and not just to eliminate requirements the licensee sees as desirable. For those cases when risk increases are proposed, the benefits should be described and should be commensurate with the proposed risk increases. The approach used to identify changes in requirements was used to identify areas where requirements should be increased as well as where they could be reduced [Section 111.2.31. The scope, level of detail, and quality of the engineering analyses (including traditional and probabilistic analyses) conducted to justify the proposed LB change are appropriate for the nature and scope of the change and are based on the as-built and as-operated and maintained plant, including reflecting operating experience at the plant [Section 1111.2.21. The portions of the plant-specific PRA relevant to the application should contain the characteristics and attributes of a PRA as defined in Appendix A to Regulatory Guide 1.174. It should also be subjected to an independent peer review to determine whether it contains those characteristics and attributes [Section 111.2.21. The plant-specific PRA supporting the licensee's proposals has been subjected to quality assurance methods and quality control methods [Section 111.2.2]. * Appropriate consideration of uncertainty is given in analyses and
