1) October 1999 7.2-3 NUREG-1555 ` meteorological data for a 1-year period represents current conditions (from ESRP 2.7) ` socioeconomic impacts that might be associated with emergency measures during or following an accident (from the ER) ` radiological dose consequences and health effects associated with normal and anticipated operational releases (from ESRP 5.4.3). II. ACCEPTANCE CRITERIA Acceptance criteria for the review of environmental impacts of postulated accidents involving radioactive material and related to the plant are based on the relevant requirements of the following: ` 10 CFR 52.17 with respect to applications for early site permits ` 10 CFR 52.79 for combined licenses with regard to requirements in 10 CFR 50.34 for the analysis and evaluation of the design and performance of structures, systems, and components of the facility with the objective of assessing the risk to public health and safety resulting from operation of the facility. Technical Rationale The technical rationale for evaluation of the applicant’s plant accident data is discussed in the following paragraph: The Commission decided that the events or accident sequences that lead to releases shall include, but not be limited to, those that can reasonably be expected to occur. The environmental consequences of releases whose probability of occurrence has been estimated shall also be discussed in probability terms. Although the consequences of the accidents that can reasonably be expected to occur are expressed in terms of potential exposure to individuals, the consequences of severe accidents (referred to as probabilistic accidents in the policy statement) are characterized in terms of exposure to population groups and, where applicable, to the biota. Releases refer to radiation and/or radioactive materials or both entering environmental exposure pathways, including air, water, and groundwater. In-plant accident sequences that can lead to a spectrum of releases shall be discussed and
