SRP 19-B1 APPENDIX B INTEGRATED DECISIONMAKING Risk-informed applications are expected to require a process to integrate traditional engineering and probabilistic considerations to form the basis for acceptance. In order for this decisionmaking process to be effective in rendering accurate representations of plant safety and risk, the staff anticipates that licensees will have documented guidance to ensure consistent and defensible results. Such guidance would also allow staff reviewers to reconstruct the logic and events involved in the integration process. This appendix discusses issues that the staff should address during reviews of the licensees’ integrated decisionmaking process (sometimes
