ety margin of steel and concrete structures due to the elimination of the OBE as a design requirement.140 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.141 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided in accordance with the requirements of this review plan and concludes that histhe evaluation is sufficiently complete 142 and adequate to support the following type of conclusive statement to be included in the staff's safety evaluation report (SER):143 The staff concludes that the design of the containment internal structures are acceptable and meets the relevant requirements of 10 CFR Part 50, 50.55a and General Design Criteria 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 ensuringassuring that the containment internal structures are designed, fabricated, erected, constructed, tested, and inspected to quality standards commensurate with itsthe safety function to be performed by meeting the guidelines of regulatory guides 144 and industry standards indicated below. 2. The applicant has met the requirements of GDC 2 by designing the containment internal structure to withstand the most severe earthquake that has been established for the site with sufficient margin and the combinations of the effects of normal and accident conditions with the effects of
