DEVELOPMENT OF RODOS - A COMPREHENSIVE DECISION-SUPPORT SYSTEM FOR NUCLEAR EMERGENCIES IN EUROPE - AN OVERVIEW

Within its Radiation Protection Research Programme, the Commission of the European Communities has embarked on a major project aiming at the development of an integrated and comprehensive real-time on-line deci sion support system (RODOS) for nuclear emergencies in Europe, applica ble for the vicinity of the release and the early phase up to far dist ant areas and the later stages of an accident. At present, the project is organised as a joint venture of some 18 European institutes closel y cooperating with several Russian and Ukrainian laboratories. The mai n purpose of the project is to provide the methodological basis. devel op models and data and install the hardware and software framework of RODOS. The paper describes the kev features, the overall design and th e software structure broadly accepted by the contractors. Based on thi s concept, a first prototype version of RODOS has been developed, whic h integrates programs developed by the contractors, in particular the complete software of the German real-time system RESY. This prototype is comprised of models for near-range atmospheric dispersion, early em ergency actions, dose calculations, food bans, health effects and econ omic costs. The paper sketches the present status of RODOS and gives a n overview of the important tasks of R and D work for the next project phases.
