d and approved by the NRC do not require specific review and approval prior to implementation provided that the effect of the changes on plant risk increase is insignificant. The overall ISI submittal should specify what types of changes without prior NRC approval are anticipated and describe how such changes will be developed, reviewed by plant personnel, documented, and implemented.  Segment inspection method changes that involve the implementation of an NRC-endorsed ASME Code, NRC-endorsed Code Case, or published NRC guidance approved as part of the RI-ISI program do not require prior NRC approval.  Inspection method changes that involve deviation from the NRC-endorsed Code requirements require NRC approval prior to implementation.  Changes to the RI-ISI program that involve programmatic changes (e.g., changes to the categorization criteria or figure of merit used to categorize components, and changes in the acceptance guidelines used for the licensee's integrated decisionmaking process) require NRC approval prior to implementation. Piping inspection method changes typically involve the implementation of an applicable ASME Code, Code Case, or other requirements approved by the NRC. Changes to the piping inspection methods 3.9.8-15 for these situations do not require NRC approval. However, inspection method changes that involve deviation from the NRC-approved Code requirements require NRC approval prior to implementation. For each area of review, the following review procedure is followed to ensure consistency in review so as to satisfy the requirements of acceptance criteria stated in Section II. III.1 Element 1: Define the Proposed Change to ISI Program The staff reviewer verifies that the licensee’s RI-ISI submittal defines the proposed changes to the ISI program in general terms. The reviewer ensures that the licensee has confirmed that the plant is designed and operated in accordance with the approved requirements and that the PRA used in support of
