selected scenario, the reasonableness of assumptions, and the degree of conservatism applied in modeling the scenario and selection of model parameters. With respect to consumption rates of water and BTP 11-6-11 Draft Revision 4 – August 2014 food products impacted by indirect uses of water, the analysis should initially apply the recommended values for the maximum exposed individual in Table E-5 of RG 1.109, “Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I.” issued October 1977. The values of Table E-5 provide initially a reasonable level of conservatism in defining consumption rates and in estimating associated doses. For scenarios that consider the consumption of fish and invertebrates, the analysis should apply appropriate bio-accumulation factors for the assumed aquatic environment. The staff will confirm the appropriateness of the selected scenario and acceptability of underlying assumptions using the information provided by the applicant and information obtained from the results of a land-use census, if available, or information gleaned from Federal, State, and local or regional sources. In its review, the health physics staff will use the radionuclide concentrations in water at the point of entry located in unrestricted areas that were calculated and determined to be acceptable by the Hydrologic Engineering staff, as described in Item 4, above. 6. SRP Dose Acceptance Criteria The health physics staff will compare the results of the analyses of radiological impacts with the appropriate acceptance criteria when assessing the acceptability of these results. The acceptance criteria presented here are based on doses to members of the public, rather than on effluent concentration limits, as was the case in previous guidance. The reason for this change is the need to better account for the effects of multiple exposure pathways. Releases may affect surface
