Functions of decision support systems (JRodos as an example): overview and new features and products

Abstract

-Under the auspices of its Euratom Research Framework Programmes, the European Commission (EC)has supported the development of the RODOS (Real-time Online DecisiOn Support) system for off-site emergency management after nuclear accidents for more than a decade. Significant additional funds have been provided by many national research programmes, research institutes and industrial collaborators. In particular, the German Ministry of the Environment, Nature Conservation and Reactor Safety financially contributed to the project with an emphasis on early emergency response. The final result of these collaborative actions, the comprehensive RODOS system, can be applied generally within and across Europe. It can be used in national or regional nuclear emergency centres, provides coherent support at all stages of an accident, and includes the long-term management and restoration of contaminated areas. Within the NERIS-TP project, several model improvements have been developed, covering the worldwide applicability of the system, the coupling with the early notification system of the IAEA, improved countermeasure modelling and model adaptation for the new ICRP 103 recommendations. Several of these new tools were also integrated into the ARGOS system (Hoe S., Müller H

JRODOS customization for Pakistan and assessment of the consequences of a hypothetical nuclear accident

“…The applicability of RODOS in the consequence analysis of a nuclear accident was implemented on various emergency scenarios and it was found to be useful to consider RODOS as a decision support tool, both for preparedness and response to a nuclear or radiological emergency. Raskob et al (2016) discussed the capabilities and functions of JRODOS and discussed its applicability at national, regional and international level and during the various stages of an emergency. Kovalets et al (2016) proposed the integration of an algorithm into JRODOS to estimate the source term that is based on gamma dose rate measurements around the facility.…”

The use of specialized software for liquid radioactive material spills simulation to teach students and postgraduate students

“…• RODOS: ADM RIMPUFF with 10-min. time step + FDMT [27]; • RASCAL (INTERRAS) [26], HOTSPOT [8] ; • ARGOS: complex terrain ADM, dose projection module (any other DSS); • simplified gaussian models; • sophisticated models for short range (CFD-, LES-modeling); • NRC MACCS code (probabilistic tool) [20]; • GENII, RESRAD, PAVAN, ARCON 96, XOQDOQ (RAMP family) [28]; etc. Worker's exposure (internal) can be assessed using analytical base and methods (NRC, ICRP, UNSCEAR [28]); dose conversion factors FGR-11/13, EPA [28]; analytic base of organization such as NRC, EPA, ICRP, and skin dose assessment in VARSKIN code; MICROSHIELD, ISOCSR to calculate dose from equipment and spill domain.…”

Source term model of radioactive liquid spills for actual decision support systems

“…Studies on thermodynamic calculations ventilation and air conditioning, experimental data of heat and mass transfer during evaporation of the liquid with a free surface, thermodynamic properties of water and steam are collected in [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Information on existing toolkit for ventilation task solving, atmospheric dispersion modelling and dose projection such as ANSYS, Solid Works, OpenFOAM, MACCS, RASCAL, HOTSPOT is concentrated in [21][22][23][24][25][26][27][28]. The report [31] is focused on the results of the AVESOME project on source term uncertainties in decision support system context.…”

“…A principal concept in the IRIX Format is the IRIX report. Any information exchanged in the IRIX Format must be packaged as the IRIX report according to [24][25][26].…”
