to the discretion of each COL applicant. The staff should ensure that applicants’ FSAR Chapter 19 contains the information needed to review the COL application, regardless of how the information is formatted or organized within FSAR Chapter 19. In the future revision of RG 1.206, Section C.III.1 will be revised in accordance with Section IV.A.2.a in each existing DCR. The structural performance of the containment under severe accident loads reviewed by the staff encompasses: (1) the applicant’s assessment of the Level C (or factored load) pressure capability of the containment in accordance with 10 CFR 50.44(c)(5), (2) the applicant’s demonstration of the containment capability to withstand the pressure and temperature loads induced by the more likely severe accident scenarios as stipulated in SECY-93-087, Section I.J, (3) the applicant’s containment structural fragility assessment for overpressurization, and (4) the applicant’s assessment of the seismic capacity of the containment structure in meeting the expectation documented in SECY-93-087, Section II.N. The staff also reviews the applicant’s 19.0-4 Draft Revision 3 – September 2012 assessment of the structural effects of postulated containment phenomenological challenges such as direct containment heating and ex-vessel explosions loads on the containment. The review and evaluation focus on the structural performance of the containment boundary as the ultimate barrier to radionuclide releases to the environment in a severe accident. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and restrictions (e.g., interface requirements and site parameters). For a COL application referencing a DC, a COL applicant must address COL action items (referred to as COL license information in certain DCs) included in the referenced DC. Additionally, a COL applicant must address requirements and restrictions (e.g.,
