REVIEW RESPONSIBILITIES Primary - Structural Engineering Branch (SEB)Civil Engineering and Geosciences Branch (ECGB)1 Secondary - None I. AREAS OF REVIEW The following areas relating to the design of structures that have to withstand the effects of the design basis tornado specified for the plant are reviewed to assureensure conformance with the 2 requirements of General Design Criterion 2 (GDC 2) (Ref. 1). 3 4 1. The design parameters applicable to the tornado, including the tornado wind translational and tangential velocities; the tornado-generated pressure differential and its associated time interval; and the spectrum of tornado-generated missiles, including their characteristics, are reviewed from the standpoint of use in defining the input parameters for the structural design criteria appropriate to account for tornado loadings. The bases for the selection and the values of these parameters are within the review responsibility of the Accident Evaluation Branch (AEB) as stated in SRP Sections 2.3.1, 2.3.2, and
