ss 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. SRP 19-B2 • Deliberations should be application-specific. The objectives proposed for the integrated decisionmaking process for a particular application (particularly, how the 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. • The decisionmaking team should have been advised of the specifics of all proposed changes and the relevant background information associated with the licensing action. In addition, since the judgement will depend, in part, on the results of a risk analysis, it is important that all team members be provided with an interpretation of the results of the risk model and the potential limitations of that model. • The licensee's integrated decisionmaking process should take into account the principles and expectations described in Section II of this SRP chapter. • In formulating the findings, the licensee should account for both probabilistic and traditional engineering considerations. This should include information from the risk analysis, traditional engineering evaluations and insights, quantitative sensitivity studies, operational experience and historical plant performance, engineering judgment, and current regulatory requirements. Potential limitations of the risk model should be identified and resolved. In addition, the licensee should individually consider and evaluate all SSCs that are affected by the
