sign 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. 23 3269, which the staff has reviewed and found acceptable,. The methods and data provided in these documents were used to transform the wind velocity into an effective pressure on structures and for selectingto select pressure coefficients corresponding to 24 the structures geometry and physical configuration. The applicant has designed the plant structures with sufficient margin to prevent 25 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 26 specified for the plant are acceptable since these procedures have been used in the design of conventional structures and proven to provide a conservative basis which together with other engineering design considerations assuresensures that the structures will 27 withstand such environmental forces. The use of these procedures provides reasonable assurance that in the event of design basis winds, the structural integrity of the plant structures that have to be designed for the design wind will not be impaired and, in consequence, safety-related systems and components located within these structures are adequately protected and will perform their intended safety
