t may propose to use the changed fuel design in its COLA or may continue to reference the certified design, including the original fuel assembly design, and submit the appropriate LAR and FSAR updates following the issuance of the COL. In either case, the fuel assembly design ultimately used in the reactor will have satisfied all applicable NRC requirements. Errors in Design Certifications Referenced by Combined License Applications Once one or more COLAs have been submitted that reference the DC, additional design work is required to address COL action items (as discussed in Section C.2.11), demonstrate compliance with interfacing system requirements in the DC, include proposed ITAAC, describe site-specific design features, and demonstrate that actual site characteristics fall within the site parameters specified in the DC. Similarly, initial COL applicants may need to resolve constructability issues encountered during the construction process. In the course of this work, the DC vendor or the COL applicant or licensee may identify errors in the certified design that are of a generic nature. Regardless of whether an error in the DC is identified before or after a selected freeze point for the COLA, or in the case that no freeze point was specifically declared by the applicant, the general guidance of this regulatory topic applies. Notwithstanding the requirements in 10 CFR 52.63, the AEA requires the NRC to make the final safety finding for both construction and operation when it issues a COL. In making this finding for a COL applicant referencing a DC, the NRC relies on the safety findings made during the DC review. This reliance, however, must be reasonable. However, if the NRC knows of a significant error in the DC that undermines the statutorily required COL safety findings, the NRC may issue the COL only after the error is adequately addressed to enable the Commission to make the required findings. The resolution of a DC design error cannot be deferred until
