ironments that may, under accident conditions, transport radioactive contaminants to existing and future water users located in unrestricted areas. BTP 11-6-10 Draft Revision 4 – August 2014 See SRP Sections 2.4.12 and 2.4.13 for details on the type of information and site data that would be considered in the development of a site conceptual model and staff’s approach in evaluating the information provided by the applicant. 5. Exposure Scenarios and Acceptance Criteria The health physics staff will review exposure scenarios and assumptions describing exposure pathways associated with the release of radioactivity from a postulated failed tank and components. The scenarios include: A. Direct Water Use - This Scenario Assumes That Members Of The Public Would Consume Drinking Water Withdrawn Near Or At The Point Of Entry In An Unrestricted Area. The Sources Of Water Include A Groundwater Well, Or From A Surface Water Body Or River. B. Indirect Water Use - This Scenario Assumes The Use Of Water In Indirect Human Consumption. Such Scenarios May Include Livestock Watering Or Irrigation Of Grazing Pastures, Consumption Of Animal Products (Meat And Milk Products), Fish And Invertebrate Consumption, Crop Irrigation And Consumption Of Such Crops, Or Water Used As An Ingredient In Food Products Or In Food Processing. C. Combined Use of Water - This scenario assumes both direct and indirect water use. In such an instance, the scenarios would be modeled separately and the resulting doses would be summed up and compared to the SRP acceptance criteria. For the purpose of the consequence analysis, the point of entry in unrestricted areas is defined as a location beyond the site boundary where the applicant has no administrative controls that could be used to restrict the use of surface water or groundwater resources, or require the treatment of surface water or groundwater for use as finished drinking water. When considering surface water resources, the selected point of entry
