parameters and sources used in the impact assessment. Parameters and source documents should be defensible, and where assumptions are used to fill in missing or highly uncertain data, the assumptions should be conservative 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). • Presentation of results, including population doses, maximally exposed individual doses, and health effects for transportation crews and the general public for the following: – Workers and the public under normal transport conditions. Results should be presented for workers, onlookers, and persons along the route. – Maximally exposed individuals under normal transport conditions. Results should be presented for truck crew members, inspectors, residents along the transport routes, and persons at a truck service station. – Annual radiological and nonradiological transportation impacts. Results should be presented for the proposed site. DG-4.2, Page 119 • Computer code input and output files used to estimate transportation impacts should be provided in the ER or otherwise made available (e.g., input and output files from computer codes such as RADTRAN and TRAGIS). 6.2.2 Estimating the Number of Shipments and Normalization of Shipments The impacts presented in Table S-4 are based on a 1,100-MW(e) LWR with an 80 percent capacity factor. To facilitate comparison of transportation impacts with the impacts presented in Table S-4, the number of shipments should be normalized to a 1,100-MW(e) LWR with an 80 percent capacity factor or a net electrical output of 880 MW(e): 𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍𝐍 𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒= 𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒𝐒
