Index of hazard for radioactive waste (revised). Interim technical report PR 78-10-80R
This is an interim report of a study to establish a risk measure for radioactive waste repositories and to generate radiological performance objectives. The problem of regulating radioactive waste repositories is reviewed, and the difficulties associated with this activity are discussed. Risk-benefit analysis as a tool for regulation has been suggested, and its contribution is assessed. Decision analysis as a development of risk-benefit analysis is suggested as an alternative approach, in particular, employing the concept of expected utility. A utility function which describes the possible consequences of a radioactive waste repository is discussed in some detail, paying particular attention to the public concerns which must be addressable through such a function and how it is recommended to capture them. A specific utility function is developed, and its elicitation from a particular subject is described. The representation of public values in a decision-analytic approach presents some problems and these are fully discussed; recommendations are made as to appropriate methods to carry this out. The vexed question of determining an acceptable safety limit is studied and recommendations are made concerning the most suitable way to determine ''how safe is safe enough.'' Finally a brief discussion is given of how these concepts may be employed to generate radiological performance objectives.
