s of this SRP chapter, "risk management" refers to an approach to decisionmaking about safety that seeks to allocate available resources and worker dose in such a way as to minimize the risk to public health and safety from plant operations. The staff should recognize that there is a point of diminishing returns in risk reduction and that some residual risk will be associated with plant operation. Nonetheless, reviewers should expect that licensees will make an effort to identify reasonable and cost-effective measures to control this residual risk as part of the risk-informed regulatory process. Therefore, as a staff expectation, the process of risk management in risk-informed decisionmaking should not be biased toward eliminating requirements to the exclusion of enhancements that would convey a worthwhile safety benefit. Licensees are expected to apply risk insights in an unbiased way, and licensees who do not satisfy subsidiary safety objectives (as defined in R13 1.174) are expected to seek safety enhancements in conjunction with risk-informed applications. SRP 19-24 Therefore, when risk increases are proposed, reviewers sholid consider plant performance and past changes to the licensing basis to ensure that there is no pattern for a systematic increase in risk. Insights on the licensee's operational pjactices, management controls, risk management programs, plant configuration control programs, or performance monitoring programs from previous applications can be obtained from -the NRC project managers, the NRC regional offices, or documentation of NRC inspection activities. 111.2.3 Integrated Decisionmaking Process The acceptability of the proposed changes should be reviewed and determined in an integrated fashion. Staff reviewers should verify that the licensee has used the results of the traditional engineering analyses and the risk assessment to ensure that the submittal fulfills the principles listed in Section II of this SRP chapter.
