ith the application. If two years of onsite meteorological data are not available at the time the application is filed, the staff expects that the COL or ESP applicant will provide at least one annual cycle of meteorological data collected onsite with the application. These data should be used by the applicant to calculate (1) the short-term atmospheric dispersion estimates for accident releases discussed in SRP Section 2.3.4 and (2) the long-term atmospheric dispersion estimates for routine releases discussed in SRP Section 2.3.5. The applicant should continue to monitor the data and submit the complete 2-year data set when it has collected all the data. This supplemental submittal should also include a reanalysis of the Section 2.3.4 and 2.3.5 atmospheric dispersion estimates based on the complete 2-year data set. 3. The applicant should identify and justify any deviations from the guidance provided in Regulatory Guide 1.23. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. For power reactor site applications before January 10, 1997, 10 CFR 100.10(c)(2) states that meteorological conditions at the site and in the surrounding area should be considered in determining the acceptability of a site for a power reactor. Likewise, for power reactor site applications on or after January 10, 1997, 10 CFR 100.20(c)(2) requires consideration of the meteorological characteristics of the site that are necessary for safety analysis or that may have an impact upon plant design in determining the acceptability of a site for a nuclear power plant. These requirements to consider meteorological conditions at or near the site of a proposed nuclear power plant are imposed (a) to ensure that these conditions will not compromise the plant's safety, (b) to provide descriptions of meteorological characteristics at or near the site to facilitate making
