Content:
design of structures, systems, and components (SSCs) of a facility being constructed under a combined license (COL) covered by Title 10 of the Code of Federal Regulations (CFR), Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 1), Sections 52.98(b) and (c), “Finality of Combined Licenses; Information Requests.” Section 52.98(b) covers COLs that do not reference a certified standard design or a manufacturing license, but does cover a COL that references a standard design approval (SDA), and section 52.98(c) covers COLs that reference a certified standard design. Specifically, this RG addresses the timing of a proposed change to the design of facility SSCs during construction, as the facility design is described in the final safety analysis report (FSAR), as updated, and for which a license amendment is required by an applicable change process of 10 CFR Parts 50 or 52. Applicability This RG applies to holders of COLs issued under 10 CFR Part 52. While this RG focuses on COLs that do not reference a manufacturing license, this RG may be applicable to a COL that references a manufacturing license, but those applications would be reviewed on a case-by-case basis. Applicable Regulations • 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities” (Ref. 2) discusses the change processes applicable to information in an FSAR, as updated, for a COL for changes that are not controlled by a design certification rule (i.e., an appendix to 10 CFR Part 52). DG-1321, Page 2 o 10 CFR 50.59, “Changes, tests and, experiments,” governs changes to the facility as described in the FSAR, as updated, for a COL issued under 10 CFR Part 52 for changes that are outside the scope of a design certification rule. o 10 CFR 50.90, “Application for amendment of license, construction permit, or early site permit,” requires that a COL holder under 10 CFR Part 52 who desires to amend the license must file an application for a
