Abstract:
This report forms part of a research project aimed at establishing a framework for assessing the suitability of controlled landfills to accept disposals of solid low-level radioactive waste. The disposal of radioactive waste alongside other wastes at landfill sites is a disposal route aimed at small users rather than at the nuclear industry, and it is restricted to relatively low activity wastes. The framework comprises the overall process for determining the suitability of landfill sites for accepting certain types of low-level radioactive waste. The framework comprises four principal stages: a a a a Initial screening for potentially suitable sites. Development of the assessment context and methodology. Calculation of specific doses and radiological capacity. Authorisation decision and conditions. The framework is aimed at assessing new sites, or sites that have not previously accepted radioactive waste. For the purpose of this project, it has been assumed that all SPB disposals will be made to non-hazardous landfill sites. The framework therefore may not be applicable to inert and hazardous landfill sites. Assessments of landfill sites in terms of their environmental impacts require the identification of the sources, pathways and receptors through which environmental harm could arise. A generic set of these that encompasses the activities and environmental setting of landfill sites has been identified and conceptual models have been developed. In addition to the generic elements of the assessment context, there are elements of the assessment context that must be established on a site-specific basis. An Assessment Model implementing the framework for calculating specific doses and radiological capacities has been developed from mathematical models that describe the source-pathway-receptor linkages. This report describes the results of a Case Study using the Assessment Model to calculate specific doses and to illustrate the derivation of radiological capacities. The generic information in the assessment framework has been supplemented by site-specific data for a typical landfill site (Site A). In addition to calculations of specific doses for Site A based on reference values, this report includes results from a series of sensitivity studies aimed at building an understanding of system behaviour and highlighting areas that assessors must consider in deriving robust estimates of radiological capacity. i SNIFFER UKRSR03 a SPB Disposal of Low-Level Radioactive Waste March 2006
