“…Owing to their relatively low computational cost, Lagrangian models are widely used, for example, the FLEXPART [69] , GRAMM-GRAL [ 44 , 45 ], and RIMPUFF models [103][104][105] . The RIMPUFF model and other Lagrangian models have been integrated into the Real-time Online DecisiOn Support (RODOS) system [106][107][108][109] . It should be noted that the computational cost increases with an increase in the number of puffs or particles released into the computational domain.…”

“…The Thermodynamics and Mechanical effects can affect parameters of the hazardous sources, such as release rate, initial rise height, initial volume, etc. These source term parameters will affect the dispersion of hazardous substances in the atmosphere (Raskob and Ehrhardt 2007). By applying principles of explosion mechanics, fluid mechanics and Thermodynamics, the source term models for nuclear and chemical disasters were constructed to determine source term parameters.…”

Nuclear and chemical disasters can cause heavy atmospheric pollution hazard and threat people's lives and health. In this paper, theory and application for modeling and optimal control of such hazard is studied. The modeling is based on the simulation and visualization of atmospheric dispersion of pollutants, the source term estimation of nuclear and chemical disasters, and the risk evaluation of hazardous substances. The optimal control is based on Natural Cybernetics theory, effective and economic cost evaluation of control techniques, and optimization methods. Some applications and illustrations of modeling and optimal control are reported.

“…Since the Chernobyl nuclear accident in 1986, decision support systems (DSSs) and modelling tools have been utilized, not just to develop emergency plans for nuclear or radiological emergencies but also as decision support tools during the response and recovery phases of emergencies. Following the Chernobyl nuclear accident, the real-time online decision support (RODOS) system was developed with funding from the European Commission's Research and Technological Development Framework Programmes (Raskob and Ehrhardt 2000, Barescut et al 2011, Ievdin et al 2012. This system consists of models and databases that are used to perform assessments, presentations and evaluations of the consequences of nuclear or radiological accidents.…”

Since the Chernobyl disaster in 1986, decision support systems and modelling tools are utilized in response to nuclear and radiological emergencies. The Java-based Real-time On-line Decision Support System (JRODOS) is a decision support tool that can be utilised in response to an emergency in managing off-site radiological consequences. This article documents the customization and use of JRODOS for Pakistan. The JRODOS was tailored to the local Pakistan conditions, and a case study for a theoretical nuclear power plant accident was used to assess JRODOS's feasibility as a decision support tool. A worse case probabilistic accident scenario was used to identify zones and areas where urgent protective actions, early protective actions and food restriction and other response actions could be required. The areas and distances identified for the implementation of protective and response actions for such a hypothetical accident were found to be in agreement with the International Atomic Energy Agency (IAEA) suggested emergency planning zones and distances. Additionally, the implications of meteorological and source term input parameters on predicting the radiation doses to members of the public were investigated. It was identified that the output of such tools strongly depends on the availability and accuracy of the input parameters such as radioactive release and meteorological data. Limitations and uncertainties associated with these tools need to be considered in deciding on protective and other response actions in response to a nuclear accident. As established by the IAEA, protective and other response actions need to be applied on a graded approach taking into account the protection strategy and uncertainties and limitation in the available information and criteria, based on the conditions at the facility and off the site.
