alyses are performed and the acceptance criteria met, the facility has been constructed and will operate in conformity with the COL, the provisions of the Atomic Energy Act, and the NRC's regulations. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. Provisions for loads, loading combinations, and limits applicable to those portions of reactor internals constructed to Subsection NG, “Core Support Structures,” of the ASME BPV Code as incorporated by reference in 10 CFR 50.55a are discussed in SRP Section 3.9.3. 2. The design and construction of the core support structures should comply with the provisions of Subsection NG of the ASME BPV Code as incorporated by reference in 10 CFR 50.55a. In the Federal Register notice providing the final rule to amend the regulations to incorporate by reference the ASME BPV Codes and new and revised ASME BPV Code cases dated June 21, 2011 (76 FRN 36323), the NRC clarified that Subsection NG is incorporated by reference in 10 CFR 50.55a, but is not mandated. Therefore, Subsection NG is not an NRC requirement. Rather, the NRC considers Subsection NG to be approved for use by applicants and licensees of nuclear power plants by virtue of the NRC’s overall approval of Section III, Division 1 rules without condition. In this manner, approval of Subsection NG is similar to regulatory guidance provided in RGs in that it provides an acceptable method for
