vels would significantly impact the threatened and endangered species located in the area or in any nearby critical habitats. (c) Obtain assistance in making this evaluation from the reviewer for ESRP 5.4.4, as needed. NUREG-1555 7.2-6 October 1999 (10) Compare the offsite-dose consequences and health effects estimated by the applicant with those determined for normal and anticipated releases. In doing this, do not forget that the offsite-dose consequences from severe accidents are expressed probabilistically. IV. EVALUATION FINDINGS The depth and extent of input to the EIS will be governed by the nature of the plant accidents and their impacts on the proposed project. The following information should be included: ` a summary of atmospheric releases in severe-accident sequences (this includes the accident sequence or sequence group, the probability of the accident sequence per reactor year, and the fraction of the core inventory released) ` a summary of the environmental impacts and probabilities of severe accidents (including the probability of impact per reactor-year, the number of persons exposed to doses greater than 2 sieverts (200 rem) and greater than 0.25 sievert (25 rem), the population exposure, the number of latent cancers, and the cost of offsite mitigating actions) ` a summary of early fatalities and probabilities (including the probability of impact per reactor-year) ` the average values of environmental risks resulting from accidents per reactor-year (see NUREG- 0921 [NRC 1983], Tables 5.8 through 5.13 for examples). ` a comparison of the environmental risk of severe accidents with (and contrasted to) the radiological risks associated with normal and anticipated operational releases. If appropriate, the following concluding statement may be used The environmental impacts that have been considered include potential radiation exposures to individuals and to the population as a whole, the risk of near- and long-term adverse health effects that such
