Development of a comprehensive decision support system for nuclear emergencies in Europe following an accidental release to atmosphere

Objective


On the basis of a design study prepared by FZK in 1990 and its following updates expanded and modified with ideas and contributions of all the contractors, broad agreement was achieved on the objectives, overall structure and content of RODOS. As all partners considered it highly beneficial to develop the hardware and software components as soon as possible based on the features outlined in the design study, FZK laid down the structure of a detailed software framework and its internal logic. Open and lively debates on this issue led to a commonly accepted design, which was realised as prototype Version PRTY 1.0 of RODOS in 1992/A2/.

The RODOS software framework has been developed as a transportable modular structured software package to run with a UNIX operation system and X-Windows user interface with OSF/MOTIF extensions. The data management is based on SQL standard. At present, it is implemented mainly on workstations HP 9000 models 755 and 735. The modular structure of the RODOS system and the Client-Server principle applied for modul intercommunication facilitates the integration of application software components developed by the project partners.

The "Computer-based training course on off-site emergency response to nuclear accidents" has been developed by FZK, NE, SCK/CEN and EdF.

The functionality of the current version PRTY 1.3 of RODOS is still limited to the early and intermediate stages of an accident in the distance range of a few tens of kilometers. It has been, or is in the process of being, implemented in partner institutes in Belarus, Germany, Greece, Hungary, Poland, Romania, Russia, the Slovak Republic and the Ukraine by the RODOS team of FZK; institutes in Portugal, Spain, Finland and Czech Republic have requested the system and discussions are proceeding with institutes in other European countries. Further development of the system and its component parts is now proceeding in parallel in many institutes.

Those institutes in Eastern and Western Europe, which run the current version of RODOS already or will do so in the near future, are directly or indirectly responsible for emergency management in their countries. It is their expressed objective that RODOS will become an integrated part of the national emergency management arrangements and thus will be widely used. In addition, the work on the realisation of a European wide network for the exchange of radiological information has started with the main partners of this proposal and the current RODOS users. In this way, the RODOS system will facilitate communication and exchange of information and promote a more coherent and harmonised emergency response within Europe to any future nuclear accident.
MAIN OBJECTIVE OF THE PROPOSAL IS THE DEVELOPMENT OF AN INTEGRETED AND COMPREHENSIVE REAL-TIME ON-LINE EMERGENCY RESPONSE SYSTEM FOR NUCLEAR EMERGENCIES IN EUROPE, APPLICABLE FROM THE VICINITY OF THE RELEASE TO FAR DISTANT AREAS, WHICH IS ABLE TO MAKE CONSISTENT PREDICTIONS AND ENABLES AN EASY TRANSFER OF INFORMATION AND DATA UNPERTURBED BY NATIONAL BOUNDARIES. THE MAIN AIMS OF THE SYSTEM ARE TO CONVERT ALL RELEVANT DATA AND INFORMATION WITH THE HELP OF MODELS AND PROCEDURES INTO EASY INTERPRETABLE PICTURES OF THE ACTUAL AND FUTURE RADIOLOGICAL SITUATION. IT WILL OFFER THE POSSIBILITY TO SIMULATE DIFFERENT COUNTERMEASURES IN ORDER TO ASSESS IN ADVANCE THEIR RESPECTIVE MERITS AND DISADVANTAGES IN TERMS OF DOSE OR HEALTH EFFECTS SAVED AND THE ASSOCIATED SOCIAL AND ECONOMIC COSTS. THIS WILL ENABLE COUNTERMEASURES TO BE RANKED IN TERMS OF THEIR EFFECTIVENESS AND PRACTICABILITY, AND AID IN THE SELECTION OF AN OPTIMUM APPROACH BY APPLYING ADVANCED TECHNIQUES OF INFORMATION PROCESSING, SUCH AS RULE-BASED SYSTEMS OR DECISION ANALYSIS METHODS. BESIDES ITS MAIN OBJECTIVE TO FACILITATE THE TASK OF DECISIONMAKERS IN THE CASE OF A REAL ACCIDENT, THE SYSTEM WILL SERVE AS A POWERFUL TOOL FOR EDUCATION AND TRAINING OF PERSONNEL INVOLVED IN THE DECISION-MAKING PROCESS AND IN PREPARING AND EXERCISING EMERGENCY PLANS. AT PRESENT, THE DSS IS BEING DEVELOPED AS A JOINT VENTURE OF TWELVE EUROPEAN INSTITUTES, FUNDED BY CEC UNDER CONTACT B17*0045-C AND OTHER ASSOCIATED CONTRACTS. A FIRST PROTOTYPE VERSION WILL BE PRESENTED DURING THE NEXT CEC SPONSORED INTERNATIONAL WORKSHOP ON REAL-TIME COMPUTING OF THE ENVIRONMENTAL CONSEQUENCES OF AN ACCIDENTAL RELEASE IN OCTOBER 1992. SOFTWARE PRODUCTS WILL BE MADE AVAILABLE FOR IMPLEMENTATION BY MANY OF THE CONTRACTORS. TWO MAIN RESEARCH AREAS CAN BE DISTINGUISHED IN THE NEXT RESEARCH PROGRAMME :
A. FURTHER DEVELOPMENT OF THE HARDWARE AND SOFTWARE FRAMEWORK, AND IMPROVEMENT AND COMPLETION OF THE MODEL AND DATA INGREDIENTS.
B. APPLICATION OF THE SYSTEM FOR EDUCATION, TRAINING AND EXERCICES. ALL ACTIVITIES RELATED TO METEOROLOGICAL AND ATMOSPHERIC DISPERSION MODELLING FOR REAL-TIME APPLICATIONS ARE COVERED BY A SEPARATE PROPOSAL WITH RISOE NATIONAL LABORATORY, DENMARK, AS COORDINATOR. BOTH PROJECTS WILL BE FULLY INTEGRATED.
