escribed in Review Interfaces, are reviewed on a case-by-case basis. 2. After the acceptability of the site-related parameters is established, the reviewer proceeds to review the structural aspects of tornado design in the following manner: A. The procedures used by the applicant to transform tornado wind effects into design loads for structures are reviewed and compared with the procedures delineated in ASCE/SEI 7-05 and, in particular, with the acceptance criteria delineated in this SRP Acceptance Criteria, subsection 3.B. B. The procedures used by the applicant to transform atmospheric pressure change effects into design loads for open and enclosed structures are reviewed and compared with the procedures described in this SRP Acceptance Criteria, subsection 3.C. The procedures used by the applicant to transform tornado-generated atmospheric pressure change effects into loads for partially enclosed structures are reviewed on a case-by-case basis. C. The review procedures for missiles generated by tornadoes are described in SRP Section 3.5.1.4. The review procedures for design of missile barriers are described in SRP Section 3.5.3. 3. The information provided to demonstrate that failure of any structure or component not designed for tornado loads will not affect the capability of other SSCs to perform necessary safety functions is reviewed. 4. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. 3.3.2-8 Revision 3 -
