The RODOS project

The developement of the Real-time online decision support system RODOS is a major item in the area of radiation protection of the European Commission’s Framework Programmes. In parallel, the German Ministry of Environment, Nature Conservation and Reactor Safety (BMU) financially contributed to the project with emphasis on early emergency response. The main objectives of the RODOS project have been: and, the overriding consideration, The project began modestly in 1989 with a small number of partners. Participation and geographical coverage increased progressively during the 3rd and 4th European Commission Framework Programmes. By the end of the 4th Framework Programme, some 40 institutes from about 20 countries in the Union and in Eastern Europe (CEEC and NIS) were actively involved in the project. The RTD has been carried out within seven separate, but fully integrated, contracts. Karlsruher Institut fü Technologie has coordinated the project throughout and, inter alia, has overall responsibility for developing the system and integrating the software products of the other contractors. A comprehensive description of the RODOS project and system is given in the Final Report at the end of the European Commission’s 4th Framework Programme.

The RODOS system is being further developed under the European Commission’s 5th Framework Programme within the following contracts:

In addition, an international network has been established on

Future work

The RODOS system will be further enhanced for operational applicability in national emergency management centres under the EURANOS Project of the EC’s 6th Framework Programme (FI6R-CT-2004-508843), co-ordinated by Forschungszentrum Karlsruhe (4/2004 to 3/2009). The main objective of EURANOS is to bring together best practice, best knowledge and best technology to provide an enhanced foundation for Europe’s future response to any radiation emergency. It fully integrates 17 national emergency management organisations with 33 research institutes.  

RODOS installations

As a result of the European Commission’s OSEP activities, the implementation of the RODOS system in national emergency centres of Poland, the Slovak Republic, Hungary, the Ukraine and Slovenia was completed with support of ECHO, TACIS and PHARE between 2000 and 2004. Further installations are planned in other East European countries for the next years with support from the European Commission, such as the Czech Republic, Russia, Bulgaria and Romania. The following list shows the institutions who operate the RODOS system in these countries. In Germany, the RODOS System has been installed for operational use at the Bundesamt für Strahlenschutz (BfS), Neuherberg. Altogether ten main users will access the RODOS Centre, seven of them responsible for emergency management in their Federal States and three of them acting on the national level. To that purpose, RODOS has been coupled with the nuclear reactor remote monitoring systems (KFÜs) and the German Integrated Monitoring and Information System (IMIS). Weather forecasts and long range atmospheric dispersion calculations will be provided by the German Weather Service (DWD).

RODOS centre

A number of West European countries have taken the decision to use the RODOS system for (test-) operational application, such as Finland, The Netherlands, Spain and Portugal, and installation plans exist in Belgium and Austria.  

The RODOS Consortium

Those institutes who have commonly developed the RODOS system under the 5th and/or 4th Framework Program by providing software components together with the corresponding documentation, build the RODOS Consortium. These are currently:

Levels of support

RODOS has been designed as a comprehensive system incorporating models and databases for assessing, presenting and evaluating accident consequences over all distances. It can be applied at all distances from the release site, and takes account of emergency actions and countermeasures. It can be used from the moment that an accident threatens, through to long-term actions implemented months or years after an accident.

RODOS provides support ranging from largely descriptive reports (Levels 0-2) to a detailed evaluation of the benefits and disadvantages of various strategies and their ranking to the societal preferences expressed by the decision makers (Level 3). The system uses monitoring data and field measurements to improve the accuracy of its modelling of atmospheric and hydrological dispersion and radioecological processes.

Modular design

The conceptual RODOS architecture is split into three distinct subsystems, which are denoted by Analysing Subsystem (ASY), Countermeasure Subsystem (CSY) and Evaluating Subsystem (ESY). They provide information on the Levels 1 to 3 as described above. The interconnection of all program modules, the input, transfer and exchange of data, the display of results, and the interactive and automatic modes of operation are all controlled by the specially designed UNIX based operating system OSY with client-server functions.

Interfaces of RODOS to data providers

The RODOS system offers appropriate interfaces to plant safety, radiological and meteorological networks:

The analysing subsystem ASY

Main task: continuously updated diagnosis and prognosis of the radiological situation.

The main modules integrated in ASY are

The countermeasure subsystem CSY

Main task: estimation of the extent and duration of countermeasures together with their consequences.

To that purpose, CSY contains

The evaluation subsystem ESY

Main task: evaluation and ranking of optional countermeasure strategies by balancing their respective benefits and disadvantages including

User categories

Category A: Active user with full functionality, direct access to the RODOS System via the X-Windows based User Interface (X-Terminals or PCs with X-Windows emulation) Category B: Active user with limited functions, access to the system via WWW interface tools on PCs with WWW Browser and graphics terminal Category C: Passive user, access to results of (A) and (B) via WWW tools on PCs with WWW Browser and graphics terminal according to access rights  

RODOS version PV6.0

The RODOS Version PV6.0 for operational use in emergency centres has been released in May 2004. They run on Hewlett Packard workstations and servers with processor architecture HP-PA2.0 with UNIX 11.0; only FORTRAN 90 is accepted. A LINUX version of RODOS PV6.0 is planned to be released within the first half of 2005.
