ction II of this plan. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided to satisfy the requirements of this SRP section, and concludes that his evaluation is sufficiently complete and adequate to support the following type of conclusive statement to be included in the staff's safety evaluation report: The staff concludes that the plant design is acceptable and meets the require- ments of General Design Criterion 2. This conclusion is based on the. following: The applicant has met the requirements of GDC 2 with respect to the capability of the structures to withstand design wind loading so that their design reflects 1. appropriate consideration for the. most severe wind recorded for the site with an appropriate margin; 2. appropriate combinations of the effects of normal and accident conditions with the effects of the natural phenomena; and 3. the importance of the safety function to be performed. The applicant has met these requirements by using ANSI A58.1 and ASCE paper No. 3269, which the staff has reviewed and found acceptable, to transform the wind velocity into an effective pressure on structures and for selecting pressure coefficients corresponding to the structures geometry and physical configuration. The applicant has designed the plant structures with sufficient margin to prevent structural damage during the most severe wind loadings that have been determined appropriate for the site so that the requirements of Item 1 listed above are met. In addition, the design of seismic Category 1 structures, as required by Item 2 listed above, has included in an acceptable manner load combinations which occur as a result of the most severe wind load and the loads resulting from normal and accident conditions. The procedures used to determine the loadings on structures induced by the design wind specified for the plant are acceptable since these procedures have been used in the design of conventional structures and proven to
