Evaluation strategies for nuclear and radiological emergency and post-accident management

Abstract

In nuclear and radiological emergency and post-accident management decisions on countermeasures and remediation strategies have to be made. Whereas in the early phase decisions on emergency actions must be made in a very short time, according to emergency plans and dose thresholds, in the recovery phase complexity is higher. But there is also more time for evaluating alternative countermeasures and remediation strategies with respect to several goals. In this paper evaluation strategies supporting the decision makers throughout all phases are presented. The applied decision support techniques range from graphical presentations of decision relevant information about the alternatives for action to multi-criteria decision making (MCDM) methods. In particular methods to cope with several types of uncertainties inherent in the different phases are presented. By the integration of these techniques, the decision support system RODOS is able to provide support for more conscious, transparent and coherent decision making. © EDP Sciences, 2010.
