Content:
able while it is out of service for maintenance and testing, there are no immediate nuclear safety consequences for a new facility if facility construction has not been completed and fuel has not been loaded. Given the lack of safety consequences, the NRC has determined to allow licensees to construct SSCs in accordance with changes to the design described in the FSAR, as updated, subject to 10 CFR 52.98(b) or (c)(2) or departures from Tier 2 subject to 10 CFR 52.98(c)(1) for which the licensee has sought or will seek an amendment from the NRC. Under this guidance, such construction will be subject to certain conditions that the licensee must satisfy before it submits the ITAAC notification letter for the SSC to the NRC under 10 CFR 52.99(c)(1) or 10 CFR 52.99(c)(2). This would be consistent with current practice for operating plants, under which licensees may install and test modifications (e.g., during an outage) in parallel with NRC review of required license amendment requests. Before a 10 CFR Part 52 licensee constructing a facility declares an ITAAC complete by submitting an ITAAC closure notice, the design of the SSCs required to meet that ITAAC must be consistent with the design described in the FSAR, as updated, and Tier 2 of the plant-specific DCD. Licensee configuration management programs ensure that changes are properly controlled. The configuration management programs, along with inspections and the ITAAC process itself, provide assurance that the plant is constructed in accordance with the license. Through the NRC’s Construction Inspection Program (CIP), the NRC staff uses inspections of construction activities to independently verify that the licensee successfully carries out construction activities and identifies and corrects deficiencies that may have 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,
