Project summaryThe purpose of the project is creation of a multitarget complex of computer systems for decision support on liquidation of the long-term consequences of a nuclear accident and rehabilitation of contaminated territories with consideration of radiological, ecological, economic and social factors.
On the basis of integration of original methods, mathematical models and computer modules along with the use of up-to-date GIS- and Internet technologies the following four prototypes of the GIS-DSS are planned to be developed in co-operation with project collaborators.
1. For investigating the consequences of radioactive contamination of territories with long-lived radionuclides and analyzing various strategies of intervention (with introduction in specialized centres/institutes of Russia and collaborating countries).
2. For (site specific) decision support on liquidation of the consequences of radioactive contamination and rehabilitation of contaminated territories (with introduction in regional and local centres for support of monitoring network and rehabilitation of territories of Bryansk region (Russia) subjected to radioactive contamination).
3. For training and education of the experts and students on rehabilitation of contaminated territories and implementation of radiation protection principles (with introduction in specialized centres/institutes of Russia and collaborating countries.).
4. For remote access to demo version of the DSS in the framework of virtual seminars for (remote) training and education (with introduction as indicated in the items 1&3 above).
The work on realization of the project proposed would be based on research and developments carried out in contacts with collaborators within the international EU-CIS Projects JSP and ECP (1992-1996).
It should be pointed out all the items of R&D planned within the project proposed are new. Besides the work planned differ considerably from the works carried out in Russia and abroad on development of computer systems for an estimation of consequences of a nuclear accidents, including RODOS system.
The DSSs indicated, in addition to purposeful orientation to the questions of training and education, are directed towards analyzing/solving local level tasks (including active implementation of detailed map oflanduse) for the longer term period of liquidation of the consequences of a nuclear accident, whereas the RODOS as currently designed is optimised for more centralised management at regional or national levels with consideration of all the main task for the acute phase after an accident. Therefore, the GIS-DSSs planned are fully complementary to the RODOS system. In addition, the discussions with the RODOS developers and managers on the use of experience gained are planned.
During the realization of the Project proposed the significant attention would be paid to the scientific investigations and development of mathematical models. These works will be carried out in the close co-ordination with the Collaborators of the Project.
The questions of the implementation of GIS-systems for representation and analysis of various factors in a context of research and decision support will be studied in collaboration with NRPA (Norway), CEPN (France), NRPB (England) and RISO (Denmark).
In collaboration with the NRPA (Norway) research will be carried out on the analysis of fluxes of radionuclides in food production system (with consideration of dietary surveys, whole-body measurements, and studies of radionuclides fluxes in agricultural and semi-natural ecosystems (food chains) for a correct calculation of internal population doses) including assessments of inhomogeneities and uncertainties. Mathematical models and GIS techniques will be used to integrate data and model identifying vulnerable areas taking into account radioecological, ecological, social and economic factors (and fluxes of radionuclides mentioned above). The significant attention in collaboration with the NRPA will be paid to the analysis of the strategy of restoration/rehabilitation of contaminated areas along with an assessment of radiological and socio-economic effects of countermeasure implementation. Analysis and assessments indicated would be based on the use of original radioecological data and DSS, which will be developed within the project proposed.
Joint R&D with the CEPN (France) will include developing and using GIS for management of contaminated territories at a local level with consideration of social and demographic factors. The significant attention will be paid also to creation of training and educational systems on the basis of the use of computerized DSS and up-to-date computer and information technologies. Within the collaboration the experience of CEPN on creation of training systems as well as investigation on analysis of social factors and their role in process of rehabilitation of contaminated territories will be used. During the project implementation CEPN plans to take active participation in joint study and designing of structure of the specified DSSs, and also in the subsequent their introduction at the CEPN and use within the national and European projects on the problems of managing contaminated territories. Besides, in the close co-operation with CEPN the following project items will be also realized: "library of electronic maps", "models and computer modules for the analysis of various protective measures", "multilevel stochastic dose models".
In collaboration with the NRPB (England) the questions of the use of GIS for representation and analysis of the characteristics of contaminated areas as a component of
decision making will be examined. Joint R&D on application of methodology of "linked objects" (SOLO) to be developed within the project are planned. The investigations and computer developments indicated above will be linked with the works are being carried out at NRPB on the use of object-oriented GIS, as well as with creation of computer modules and databases for use in local and Internet- distributed systems. Besides, the package of joint works will include also questions of development of multicriteria models/modules for decision-making support on rehabilitation measures along with analysis of uncertainties and their influence on making decision.
In contact with RISO (Denmark) the questions of radiation protection optimisation and estimation of intervention levels, development of the appropriate models and computer modules for practical application of the specified principles and methods with the use of up-to-date computerized DSS to be developed for analyzing intervention measures on territories subjected to radioactive contamination will be considered. The significant attention will be paid also to research on decision support based on the risk analysis.
The plan of research and development currently proposed may be amended or items added as a result of further discussions with the collaborators and as opportunities arise during the project realization.
The direct development of computer modules and systems planned within the project will be carried out by the participants of the project; however the elaboration of approaches, methods, models and computer modules, discussion of the structure and interface of DSS to be developed and their introduction, as well as the researches will be carried out in close co-operation with the collaborators of the project.
For the project realization data on radioactive contamination of territory of Russia after Chernobyl accident (more detailed than data presented in the Atlas of 137Cs contamination of Europe after the Chernobyl accident), data on migration of radionuclides in trophic chains and the characteristics of protective measures will be used. Methods of the system analysis with reference to the class of problems indicated with consideration of radioecological, ecological, social and economic factors will be used; methods of mathematical modeling with implementation of statistical and probabilistic approaches, optimal control, differential equations, numerical methods etc. will be key ones when developing models specified; methodology of decision-making support will be based on the implementation of the principles of radiation protection and multiattribute analysis taking into account knowledge expert base, additional restrictions and constraints.
When developing computer codes/modules and integrated computerized systems/DSSs principles and methods of system- and object-oriented programming will be used; the following tools will be implemented within the project for creation of applications: C++, Java, ObjectPAL, DBMS Paradox, cartographic package PC ARC/INFO, and SDE SQL technology.
The basic works will be realized on PC's Pentium under MS Windows'95; some applications connected with distributed systems, (remote) training and education will be implemented also under UNIX (on workstation Sun) with the use of World Wide Web technology.
