ed, in applications docketed with the NRC as of the effective date of this BTP, to specific guidance in assessing the radiological consequences of a postulated failure of a tank containing radioactive materials. 4. Calculations of Transport Capabilities in Groundwater or Surface Water The Hydrologic Engineering staff will make independent calculations of transport mechanisms and potential contamination pathways to surface water and groundwater BTP 11-6-10 Revision 4 – January 2016 environments that may, under accident conditions, transport radioactive contaminants to existing and future water users located in unrestricted areas. 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scenarios include: A. Direct Water Use - This Scenario Assumes That Members Of The Public Would Consume Drinking Water Withdrawn Near Or At The Point Of Entry In An Unrestricted Area.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
