Decision support issues in RODOS: The needs of decision makers

RODOS will be used by a great variety of different decision makers from different backgrounds and with different skills and knowledge bases. In the early hours the users will be the plant management and local emergency planners; later, regional and national politicians and government officials will become involved. In addition, a great number of technical experts and advisors will interact with RODOS. In recent years, the CEC has sponsored a number of investigations and exercises to identify the support that the decision makers perceive that they need. The results of these are reported.
