wer 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 atmospheric dispersion estimates for both postulated accidental and expected routine airborne releases of effluents, and (c) to compare offsite data sources for determining the appropriateness of climatological data considered during the plant phase. Meeting these requirements provides assurance that severe weather conditions will not compromise the safety of the proposed nuclear power plant and that sufficient meteorological data are available to make representative estimates of atmospheric dispersion. 2.3.3-6 Revision 3 - March 2007 2. For power reactor site applications before January 10, 1997, 10 CFR 100.11(a) specifies the manner in which the EAB, LPZ, and population center distance 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 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 diffusion characteristics. Diffusion characteristics are determined from meteorological measurements taken at the proposed plant site. 3. For power reactor site applications 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) radiological effluent release limits associated with normal operation from the type
