ave an impact on the ITAAC or other construction activities. The staff implements the CIP through Inspection Manual Chapter 2503, “Construction Inspection Program: Inspections of Inspections, Tests, Analyses and Acceptance Criteria (ITAAC) Related Work” (Ref. 13). The results of the CIP are an essential part of the basis for the staff’s determination, in accordance with 10 CFR 52.103(g), that the acceptance criteria have been met. CIP activities can continue while a licensee is constructing SSCs whose design departs from the FSAR, as updated. If the inspection program identifies an SSC that does not match the design described in the FSAR, which would otherwise have been reported as construction findings, the NRC staff will consider the as-found condition of the SSC in connection with pending license amendments, requests for new amendments, and changes to or departures from SSC designs made without NRC approval in accordance with the change process in Section VIII of the appendices to 10 CFR Part 52 or 10 CFR 50.59. DG-1321, Page 7 The foregoing background and discussion applies only to the design of a facility described in an FSAR, as updated, including Tier 2, but not Tier 1, as described below. The rationale set forth in the final Statement of Considerations for the 1999 rule amending 10 CFR 50.59 for the Commission’s position with respect to operating plants applies to changes governed by 10 CFR 50.59, which corresponds to the change process in Section VIII.B.5 for Tier 2 information. That rationale does not correspond to any provision of Section VIII.A, which governs generic changes to and plant-specific departures from Tier 1. Accordingly, the foregoing rationale for the process applicable to operating plants under Part 50 applies under Part 52 only to the information in the FSAR, as updated, for a facility under construction pursuant to a COL covered by 10 CFR 52.98(b) or the information in the FSAR, as updated, including Tier 2 but not Tier 1 for a
