Content:
the regional meteorological data from Standard Review Plan (SRP) Section 2.3.1) are used to specify design requirements for structures, systems, or components of the nuclear plant that may be affected by the meteorological phenomena. Meeting these requirements will provide assurance that structures, systems, and components important to safety will be designed to withstand the effects of natural phenomena, thus preventing meteorological phenomena from initiating accidents at the nuclear plant.15 2. 10 CFR 100.10(c)(2) specifies that meteorological conditions at the site and in the surrounding area should be considered when evaluating the acceptability of proposed sites for nuclear power plants. The requirement to consider meteorological conditions at and near the site is imposed so that atmospheric diffusion for the proposed plant site can be determined and so that radiological doses from airborne effluents from the plant can be calculated. This calculation is performed (a) for normal operating conditions to demonstrate that offsite doses do not exceed either the limits specified in 10 CFR Part 20 and (b) for postulated accidents to demonstrate that offsite doses do not exceed the guideline doses stipulated in 10 CFR Part 100. Meeting this requirement provides assurance that offsite doses during normal operation and as the result of accidents will not exceed those specified in applicable regulations.16 III. REVIEW PROCEDURES The procedures outlined below are used during early site permit, CP, or COL reviews to determine whether meteorological data and analyses meet the acceptance criteria given in DRAFT Rev. 3 - April 1996 2.3.2-4 subsection II of this SRP section. For review of OL or COL applications in which an early site permit is referenced, these procedures are used to verify that meteorological data and analyses remain valid and that the facility's design specifications are consistent with these data. OL and COL reviews include a determination that the content
