ds derived by the applicant from these parameters to assureensure that they are 27 28 consistent with those contained in the SRP sections stated above.29 2. After the acceptability of the site-related parameters is established, the SEBECGB30 reviewer proceeds with his to review of the structural aspects of tornado design in the 31 following manner: a. The procedures used by the applicant to transform tornado wind velocities into effective pressures are reviewed and compared with those procedures delineated in either ASCE Paper No. 3269 or in ANSI A58.1, whichever is selected, and, in particular, with the acceptance criteria delineated in subsection II.3.a. b. Where venting is used, procedures for transforming the tornado-generated differential pressure into an effective reduced pressure are reviewed, upon DRAFT Rev. 3 - April 1996 3.3.2-6 request, by the Auxiliary Systems Branch (ASB) upon SEB request by SPLB as requested by ECGB. 32 c. The treatment of tornado-generated missiles is covered in SRP Section 3.5.1.4 and the review procedures for design of missile barriers are described in SRP Section 3.5.3. d. After procedures for determining the individual tornado effects are reviewed, the manner in which these effects are then combined to arrive at the most adverse total tornado effect is reviewed and compared with the acceptance criteria delineated in subsection II.3.d. Other proposed methods which may depend upon the geometry and configuration of a particular structure are reviewed on a case-by-case basis. 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 structures or components to perform necessary safety functions is reviewed to assureensure that one of the 33 acceptance criteria of subsection II.4 is satisfied. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP
