estimated using information specific to the proposed site (e.g., by using county-specific accident statistics). The following information should be provided: • Summary of provisions for site access during operations, including during outages. • Description of the method(s) used to estimate nonradiological traffic-related accident impacts, including nonradiological traffic accidents, injuries, and fatalities. Nonradiological traffic-related accident impacts should be estimated using round-trip distances. • Specification of input parameters and sources used in the impact assessment. Where assumptions are used to fill in missing or highly uncertain data (e.g., commute distances and persons per vehicle, number of deliveries), the assumptions should be bounding and reasonable (i.e., the assumptions tend to overstate transportation impacts yet are not so conservative that they could mask the true environmental impacts of the reactor and lead to invalid conclusions). • Annual number of traffic accidents, injuries, and fatalities. • Computer code input and output files used to estimate transportation impacts. 5.9 Radiological Health during Normal Operation The applicant should evaluate the potential radiological impacts to the public, workers and nonhuman biota that includes the radiological sources from operation of the proposed facility. This includes a discussion of the estimated radiation dose to members of the public, workers, and to the biota inhabiting the area around the proposed site. The ER should use the same units of measure as used in the final safety analysis report (FSAR). DG-4026, Page 97 5.9.1 Exposure Pathways The applicant should provide the following in the ER: • The environmental pathways by which radiation from radioactive effluents can be transmitted from the proposed plant to living organisms. Figure 5-1 identifies the exposure pathways to humans and Figure 5-2 addresses the exposure pathways to nonhuman biota. • The sources of direct
