If the applicable change process requires an amendment to authorize the change or departure, any such amendment is treated in accordance with 10 CFR 50.90. Further, 10 CFR 52.99 requires a licensee to notify the NRC that prescribed inspections, tests, and analyses have been performed, and that prescribed acceptance criteria are met. The staff considers the following acceptable for construction of a facility pursuant to a COL to comply with the design described in the facility FSAR, as updated, including Tier 2 and to comply with the notification requirements of 10 CFR 52.99: 1. If the applicable change process requires a license amendment, a combined license holder may construct an SSC in accordance with a change to the facility described in the FSAR, as updated, for a COL covered by 10 CFR 52.98(b) or (c)(2) or a departure from Tier 2 of the plant-specific DCD for a COL covered by 10 CFR 52.98(c)(1), without first obtaining a license amendment, provided that the following conditions are satisfied: a. A licensee must submit the request for a license amendment required to authorize the change to the facility or departure from Tier 2 of the plant-specific DCD within 45 days after the licensee begins construction of the SSCs subject to the change or departure. Submission of a license amendment request on this schedule would allow for time sufficient to process the license amendment request so that the ITAAC findings and fuel load are not delayed. b. Under this process, a licensee is not permitted to begin construction in accordance with a change to the design as described in the FSAR, as updated, or a design that departs from Tier 2 unless the SSC under construction is located within the restricted area defined in 10 CFR Part 20 and described in the FSAR, as updated, or Tier 2. c. If the NRC does not approve a request for a license amendment as submitted, the licensee is obligated to construct
