on on request. This information should be available for NRC review and audit. If changes are planned to the ISI program based on internal procedures and without prior NRC approval, the licensee should also place the following information in the plant’s document control system so that the analyses for any given change can be identified and reviewed. The record should include, but not be limited to, the following information: a. all the documentation discussed in Section C.4.1; although the documentation requirements in a submittal may be reduced when referring to NRC-approved topical reports, all the documentation included under Section C.4.1 should be available for onsite inspection b. plant and applicable industry data used in support of the RI-ISI program, including all analyses and assumptions used in support of the RI-ISI program and communications with outside organizations supporting the RI-ISI program (e.g., use of peer and independent reviews, use of expert contractors) c. detailed procedures and analyses performed by an expert panel, or other technical groups, if relied upon for the RI-ISI program, including a record of deliberations, recommendations, and findings d. documentation of the plant’s baseline PRA used to support the ISI submittal that is of sufficient detail to allow an independent reviewer to ascertain whether the PRA reflects the current plant configuration and operational practices commensurate with the role the PRA results play in the integrated decisionmaking process and, in addition to documentation on the PRA itself, analyses performed in support of the ISI submittal in a manner consistent with the baseline documentation, including such analyses as the following: (1) the process used to identify initiating events developed in support of the RI-ISI submittal and the results from the process (2) any event trees and fault trees developed during preparation of the RI-ISI submittal (3) documentation of the methods and techniques used to
