REVIEW RESPONSIBILITIES Primary - Organization responsible for structural analysis reviews Secondary - None I. AREAS OF REVIEW The following areas are related to procedures utilized in the design of seismic Category I structures, shields, and barriers to withstand the effects of missile impact. These areas are reviewed to ensure conformance with 10 CFR 50, Appendix A, General Design Criterion (GDC) 2 and 4. The specific areas of review are as follows: 1. Procedures utilized for the prediction of local damage in the impacted area. This includes estimation of the depth of penetration and, in case of concrete barriers, the potential for generation of secondary missiles by spalling or scabbing effects. 2. Procedures utilized for the prediction of the overall response of the barrier or portions thereof due to the missile impact. This includes assumptions on acceptable ductility ratios where elasto-plastic behavior is relied upon, and procedures for estimation of forces, moments, and shears induced in the barrier by the impact force of the missile. 3.5.3-2 Revision 3 - March 2007 3. The adequacy of missiles' parameters cited in support of the applicant's conclusions concerning their suitability for the plant and the effects of missiles on structures, systems, and components (SSCs). The staff also reviews the missiles parameters as an integral part of structural analysis. 4. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the SSCs related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of
