Υ Υ 1An ESP application should contain site characteristic values corresponding to all of the site parameter values listed in each of the DCs referenced in the ESP application. All of the referenced DC site parameter values should fall within (i.e., be bounded by) the corresponduing site characteristic values. 2Distances to the EAB and LPZ need not be included as site parameters in the DC application. The site-specific EAB and LPZ distances are used to calculate the EAB and LPZ χ/Q site characteristic values in the ESP and COL applications per SRP Section 2.3.4. The site-specific EAB and LPZ χ/Q values are then compared to the corresponding EAB and LPZ χ/Q site parameter values in the DC. 3External hazards (except for hurricane and tornado missiles; and if toxic chemicals are onsite and storage is identified for DC) are not typically within the scope of the DC and only onsite sources are evaluated in the DC. However, the DC should demonstrate that the potential external hazards are not design basis accidents. 4The depth of the Extreme Liquid Winter Precipitation Event may or may not be a relevant DC site parameter, depending on the geometry of the roofs and the type of drainage provided. 5For those plants with emergency active cooling system designs where the UHS is within the scope of the DC, the DC should have COL Information Items directing the COL applicant to complete analyses in accordance with Regulatory Guide 1.27 demonstrating that (a) an adequate 30-day cooling capacity is available during historic meteorological conditions that result in maximum evaporation and (b) the design-basis temperatures of equipment that is important to safety are not exceeded during historic meteorological conditions for minimum heat transfer to the atmosphere. 2.0-14 Revision 1 – October 2016 SRP Site Characteristic DC Site Site Characteristic/Site Parameter Section ESP(1) COL Parameter Design-Basis Tornado Parameters Maximum Horizontal Wind Speed Translational Speed
