n materials and personnel to and from the proposed site during building. Where possible, the impacts should be 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 building, including during outages of co-located operating units. • Description of the method(s) used to estimate nonradiological traffic-related accident impacts, including traffic accidents, injuries, and fatalities. Traffic-related accident impacts should be estimated using round-trip distances. The impacts should account for both construction workers and shipments of construction materials. • Specification of input parameters and sources used in the impact assessment. Parameters and source documents should be defensible and should be consistent with parameters used for socioeconomic analysis to determine physical impacts to road and traffic assessments for key roads. If assumptions are used to fill in missing or highly uncertain data (e.g., commute distances, persons per vehicle, and shipping distances for materials), the assumptions should be bounding and reasonable (i.e., the assumptions used in the analysis would be broad enough to overestimate the transportation impacts yet not so broad 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. 4.9 Radiological Health The applicant should evaluate the potential radiological impacts on the proposed project’s construction workforce that includes the radiological sources located on the project site or adjacent to the site, such as an operating or shutdown nuclear plant or other nuclear fuel-cycle facility. For multi-unit or multi-modular reactors, the applicant should provide estimated annual doses to
