Content:
the scope of the review is dependent on whether the COL applicant references a DC, an ESP or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's SER. The reviewer also states the bases for those conclusions. The staff concludes that the design of the containment internal structures is acceptable and meets the relevant requirements of 10 CFR 50.55a, 10 CFR Part 50, Appendix B, and GDCs 1, 2, 4, 5, and 50. This conclusion is based on the following: 1. The applicant has met the requirements of Section 50.55a and GDC 1 with respect to ensuring that the containment internal structures are designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with the safety function to be performed. 3.8.3-35 Revision 4 – September 2013 2. The applicant has met the requirements of GDC 2 by designing the containment internal structures to withstand the most severe earthquake that has been established for the site with sufficient margin, as well as the combinations of the effects of normal and accident conditions with the effects of environmental loadings, such as earthquakes and other natural phenomena. 3. The applicant has met the requirements of GDC 4 by ensuring that the design of the containment internal structures is capable of withstanding the dynamic effects associated with missiles, pipe whipping, and discharging fluids. 4. The applicant has met the requirements of GDC 5 by demonstrating that SSCs are not shared between units or that sharing will not impair their ability to perform
