Accident Consequence Group

Head: W. Raskob

Our area of expertise is the development of methods and tools to assist decision makers in dealing with major disasters. The focus of our application is emergency management following nuclear incidents and emergency preparedness.

Research activity:

emergency management following nuclear incidents (

In the nuclear area, our main activities are the assessments of the radiological and environmental consequences of accidental releases of radioactive material from nuclear facilities, including radiological accidents such as terrorist attacks, dirty bombs, etc. To that purpose we have developed simulation models and programming systems for the operational use within Europe capable of being customised to national and regional conditions. The decision support system RODOS was further developed in the frame of the European integrated research project EURANOS, supported by the European Commission in its 7th Framework Programme, integrating best knowledge and experience from 17 emergency management organisations and 32 research institutions. The RODOS system is installed in more than 10 European countries and also used in Germany operationally in case of nuclear emergencies.

Research activity:

Decision support for emergency preparedness

In the area of emergency preparedness, we are working in the area of the protection of critical infrastructures and the management of large-scale crisis situations by developing methods and tools to support the decision making process. Key tasks are among others the analysis of interdependencies of critical infrastructure, the simulation of countermeasures and of risk and crisis management by further development of multi-criteria approaches, case based reasoning methods and multi-agent based simulation techniques.

So far, we focus our research on measures to minimize the damage and to avoid cascading effects in the event of a widespread and prolonged power outage. This activity is also supported from 2012 onward as part of the HGF (Helmholtz-Gemeinschaft Deutscher Forschungszentren e.V.) portfolio activity "security".

The following areas of our particular interest:

Development of simulation models

  • Atmospheric dispersion and deposition
  • Behaviour of radionuclides in soil, rivers, lakes, food- and feedstuffs
  • Radiation exposure of the population and health effects
  • Extent and duration of emergency actions and countermeasures for the protection of the population
  • Evaluation of the benefits and disadvantages of measures and their non-radiological consequences
  • Agent-based simulation of critical infrastructure interdependencies

System development

  • Realisation of user-friendly interfaces for data input and output, and system operation
  • Software components well-balanced in their content and programming techniques
  • Application oriented presentation of results • GIS and web-based applications and services Integration of simulation models and system components
  • Interdisciplinary dialogue between model and system developers
  • continuous exchange of experiences with the end-users
