n to offset any negative impact from the proposed change. The licensee should also perform risk-inforned evaluations of the proposed change to determine the impact on plant risk. The evaluation should explicitly consider the specific plant equipment affected by the proposed TS changes and the effects of the proposed change on the functionality, reliability, and availability of the affected equipment. The necessary scope and level of detail of the analysis depends upon the particular systems and functions that are affected, and it is recognized that there will be cases for which a qualitative, rather than quantitative, risk analysis is acceptable. The licensee should provide the rationale that supports the acceptability of the proposed changes by integrating probabilistic insights with traditional considerations to arrive at a final determination of risk. The determination should consider continued conformance to applicable rules and regulations, the adequacy of the traditional engineering evaluation of the proposed change, and the change in plant risk relative to the acceptance guidelines. All these areas should SRP 16.1-5 Rev. 0 - August 1998 be adequately addressed before the change is considered acceptable. Section IlI.B provides a description of the review process for Element 2. Element 3: Define Implementation and Monitoring Program The reviewer should confirm that the licensee has consiPdered implementation and performance monitoring strategies formulated to ensure (1) that no adverse safety degradation occurs because of the changes to the TS and (2) that the engineering evaluation conducted to examine the impact of the proposed changes continues to reflect the actual reliability and availability of TS structures, systems, and components (SSCs) that have been evaluated. This will ensure that the conclusions that have been drawn from the evaluation remain valid. Section III.C provides a description of the review process for Element 3. Element 4: Submit Proposed
