REVIEW PROCEDURES A. REVIEW OF THE LICENSEE'S ENGINEERING EVALUATION 1. Evaluation of Proposed Changes The reviewer should verify that the licensee reviewed the applicable licensing-basis documents to identify proposed changes to the IST program that would affect the design, operation, and other activities of the plant. On a component-specific basis, the licensee should have (1) identified instances in which the proposed IST program change would affect the design, operation, and other activities of the plant, (2) identified the source and nature of the requirement (or commitment), and (3) documented the basis for the acceptability of the proposed requirement changes by addressing the key principles. The reviewer should consider other licensing-basis documents (e.g., Technical Specifications, FSAR, responses to NRC generic letters) in addition to the IST program documentation to identify and evaluate changes to the design, operation, and other activities of the plant. The principal focus should be on the use of PRA findings and risk insights in support of those proposed changes to a plant's design, operation, and other activities that require NRC approval. Such changes include (but are not limited to) license amendments under 10 CFR 50.90, requests for use of alternatives under 10 CFR 50.55a, and exemptions under 10 CFR 12. However, the reviewer should note that there are certain docketed commitments, that are not related to regulatory requirements that may be changed by licensees via processes other than as described in NRC regulations (e.g., consistent with Reference 9). The licensee should have identified any docketed commitments that would be affected by their proposed RI-IST program. The reviewer should evaluate the acceptability of any changes to docketed commitments 3.9.7-1 6 Rev. 0-August 1998 associated with the proposed RI-IST program (e.g., changes to commitments made by the licensee in response to NRC Generic Letter 89-10 or 96-05).
