se of integrated decisionmaking panels (or expert panels) especially in cases where there are broad applications of PRA and traditional engineering results over a large number of plant elements (Se0s, operator actions, etc.). A review of the licensee's integrated decisionmaking process would ensure a better understanding of the reasons, assumptions, approaches, and information used to justify these changes. b. Review Guidance and Procedures Since the licensee's integrated decisionmaking process is responsible for justifying the acceptability of the proposed changes to the LB, the staff anticipates that licensees will document the process in a relatively formal fashion. The staff may not routinely audit all of the licensee's findings or recommendations, but the documentation should exist to support such a review, and should be maintained for the life of the plant or until such time at which the recommendations are invalidated by later changes. Staff expectations of the integrated decisionmaking process Reviewers should ensure that the licensee's decisionmaking process contains the following attributes: The process should be well-defined, systematic, repeatable, and scrutable. This process should be technically defensible and should be sufficiently detailed to allow an independent party to reproduce the major results. Deliberations should be application-specific. The objectives proposed for the integrated decisionmaking process for a particular application (particularly, how the SRP 19-Bl results are to be utilized) should be well defined and relevant to the given application. Membership in the decisionmaking team should include experienced individuals with demonstrated skills and knowledge in relevant engineering disciplines (depending on the application), plant procedures and operations, plant systems (including operational history), system response and dependencies, operator training and response, details of the plant-specific PRA, and regulatory guidance.
