JRODOS: Platform for improved long term countermeasures modelling and management

Abstract

Abstract.One of the major objectives of the 6 th Framework EC RTD EURANOS (European Approach to Nuclear and Radiological Emergency Management and Rehabilitation Strategies) project was to improve the RODOS (Real-time on-line decision support) system in its operational applicability. In the first phase of the project two possibilities for the main system development has been discussed: either to carry out refinements in the current version of RODOS or to consider a complete software re-engineering. The RODOS Users Group (RUG) finally concluded that the latter option was one to be realised. As a result a JAVA based version named JRODOS has been developed introducing a cross-platform solution capable to run on most operation systems, including Windows, Macintosh and the main UNIX derivates. The reengineered system preserves computational models from RODOS, adding a powerful GIS support and applying modern database technologies with flexible configuration possibilities. Furthermore, these new GIS functionalities allowed implementing advanced simulation models for simulating countermeasures in inhabited areas (ERMIN -European Model for Inhabited Areas) and food production systems (AGRICPAgricultural Countermeasure Program). Both simulation models have been part of the EURANOS project and represent state of the art modelling capabilities in their respective area.

The HotSpot Code as a Tool to Improve Risk Analysis During Emergencies: Predicting I-131 and CS-137 Dispersion in the Fukushima Nuclear Accident

“…Other software packages perform simulations of dispersion, diffusion, emergency management for application in nuclear experiments, medical, accelerator and space physics studies. Among these are: a) JRODOS (Java Real-time On-line DecisiOn Support) developed by the European Commission, is a system for off-site emergency management after nuclear accidents for more than a decade [14]. b) EJS (Easy Java Simulations) Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events.…”

CONFIDENCE dissemination meeting: Summary on the scenario-based workshop

“…Contamination and transfer to soils, crops and food-chain (products), estimated using the modules of JRODOS (Raskob et al, 2011) have been presented and discussed under the scenario in Zuid-Holland. In this area, the contamination ranges among 1 to 10 MBq m À2 for 137 Cs.…”

Integration of 3D model THREETOX in JRODOS, implementation studies and modelling of Fukushima scenarios

“…Within the frame of the European research project PREPARE the 3D circulation and radioactivity transport model THREETOX (Margvelashvili et al, 1997;Maderich et al, 2008) was improved and integrated into the Hydrological Dispersion Module of the JRODOS DSS (Raskob et al, 2011). The radioactivity transport model THREETOX was extended to include the multi-fractional sediments and two-step kinetics (Periáñez, 2003;Periáñez et al, 2015a).…”
