Evaluation of Early Countermeasures and Consequences in RODOS/RESY

The paper describes the models and programme structures, methods and data in the German real-time decision support system RESY, which has been developed with the support of the Ministry of Environment (BMU), Germany. It is part of RODOS, the CEC real-time on-line decision support system for nuclear emergencies, whose first prototype version was demonstrated during the workshop. RESY, the system for near-range early phase applications, has a three steps concept of information processing: analysis and prognosis of the radiological situation, simulation of countermeasures and assessment of their consequences, and evaluation of consequences to determine the most suitable countermeasures. To that purpose, the following models have been developed and implemented in RESY: (1) a fast Gaussian puff model for atmospheric dispersion calculations and the determination of the concentration and radiation fields in the environment of the site after releases of up to 15 nuclides; (2) simulation models for early emergency actions like sheltering and evacuation, distinguishing up to five action areas with different time patterns of actions defined by intervention levels; methods for the calculation of doses with emergency actions; (3) models for calculating deterministic and stochastic somatic health effects and the economic costs associated with them and the underlying emergency actions. (4) a rule based expert system containing components of multi-attribute value techniques for evaluating and ranking alternative courses of emergency action.
