ated in relatively open country, Exposure C as defined in ANSI A58.1, should be selected for both tables. Depending upon the structure geometry and physical configuration, pressure coefficients may be selected in accordance with Section 6.4 of 3.3.1-3 DRAFT Rev. 3 - April 1996 ANSI A58.1. Geometrical shapes that are not covered in this document are reviewed on a case-by-case basis. ASCE Paper No. 3269, "Wind Forces on Structures," (Ref. 3) may be used to obtain the effective wind 13 pressures for cases which ANSI A58.1 does not cover. Technical Rationale14 The technical rationale for application of these acceptance criteria to reviewing compliance with GDC 2 is as follows: Compliance with GDC 2 requires that nuclear power plant structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami, and seiches without loss of capability to perform their intended safety functions. The acceptance criteria outlined above includes reference to proven industry standards and data for evaluating wind loading on structures. These standards and data have been reviewed by and are acceptable to the staff. Meeting the requirements of GDC 2 provides assurance that structures, systems, and components important to safety will withstand the most severe wind loads likely to occur without loss of capability to perform their intended safety functions.15 III. REVIEW PROCEDURES The reviewer selects and emphasizes material from the review procedures described below as may be appropriate for a particular case. 1. The site-related parameters described in subsection I.1 are reviewed by the Accident Evaluation Branch (AEB)PERB under SRP Sections 2.3.1 and 2.3.2. The structural 16 reviewer examines the approved values of forces and loads that the applicant derives from these parameters to assureensure that they are consistent with those contained in 17 18 SRP Sections 2.3.1 and 2.3.2.19 2.
