eteorological 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. With respect to the review under this SRP section, the regulatory requirements to consider meteorological conditions at or near the site of a proposed nuclear power plant are imposed, in part, to provide sufficient meteorological data needed for making atmospheric dispersion estimates for both postulated accidental and expected routine airborne releases of radioactive effluents. Meeting these requirements helps to ensure that these conditions will not compromise the plant’s design and operation or the public’s safety. 2. For power reactor site applications submitted before January 10, 1997, 10 CFR 100.11(a) specifies the manner in which the EAB, LPZ, and population center distances are determined given a fission product release from the reactor core, an expected leak rate from containment, and pertinent meteorological conditions. Identification of an EAB, LPZ, and population center distance is an integral aspect of the siting criteria for a nuclear power plant. Specified radiation dose guidelines are associated with the EAB and outer boundary of the LPZ. Verification that the proposed nuclear plant meets these radiation dose guidelines is accomplished by calculating expected offsite radiation doses using an assumed inventory of fission products available for release from the containment building, the expected containment leak rate, and site atmospheric dispersion characteristics. Dispersion characteristics are typically determined from meteorological measurements taken at the proposed plant site and, if necessary, other offsite locations. 3. For power reactor site applications submitted on or after January 10, 1997, 10 CFR 100.21(c) requires the evaluation of site atmospheric dispersion characteristics and the establishment of dispersion parameters such that (1)
