l from the procedures described below, as may be appropriate for a particular case. The procedures outlined below are used to review CP applications, ESP applications, and COL applications that do not reference an ESP to determine whether data and analyses for the proposed site meet the acceptance criteria given in Subsection II of this SRP section. For reviews of OL applications, these procedures are used to verify that the data and analyses remain valid and that the facility’s design specifications are consistent with these data. As applicable, reviews of OLs and COLs include a determination on whether the content of technical specifications related to regional climatology is acceptable and whether the technical specifications reflect consideration of any identified unique conditions. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. General Climate The general climatic description of the region in which the site is located is reviewed for completeness and authenticity. Climatic descriptions of air masses, general airflow, pressure patterns, frontal systems, and temperature and humidity conditions reported by the applicant are checked against standard references (References 6, 7) for appropriateness with respect to location and period of record. The applicant’s description of the role of synoptic-scale atmospheric processes on local (site) meteorological conditions is checked against the descriptions provided in References 6 and 7. 2. Regional Meteorological Averages and Extremes Estimates of meteorological averages and extremes are best obtained from stations that have long periods of record. Meteorological stations used to describe the regional climatology might not be near the site, with the
