With the support of the EU in the Exclusion Zone and at Chornobyl NPP, the RODOS system was established to support decision-making in the event of radiation accidents and emergencies
«Implementation of RODOS, the system of decision-making support, in the Exclusion Zone has greatly increased the level of rapid response to possible emergency situations, complemented and developed the existing system that existed in the Exclusion Zone. With the help of the system it is possible to assess the radiological risks associated with forest fires, tornadoes, flooding in the floodplain areas in the Exclusion Zone, as well as with the decommissioning of the ChNPP», – Vitalii Petruk, Head of the State Agency of Ukraine on Exclusion Zone Management, said during the press-conferences on the experience of implementation of RODOS in Ukraine – the European decision-making support system for radiation accidents.
According to him, the radiological situation in the Exclusion Zone is controlled by the Integrated Radiation Monitoring and Early Warning System, but the ability of the software module of this system in the modeling to this time was limited to 50x50 km, and therefore it was unable to predict the spread of radioactive substances outside the territory of the Exclusion Zone, and RODOS enables to simulate the situation within a radius of up to 2 thousand km.
«The expansion of RODOS, the decision-making support system, to the exclusion zone is another important milestone in the joint efforts of the European Union and Ukraine to overcome the consequences of the Chornobyl accident», – Vitalii Petruk said.
During a congratulatory speech, Johannes Bauer, Head of the Ecological Cooperation, Energy, Infrastructure and Environment section of the delegation of the European Union in Ukraine, emphasized that radiation safety was one of the requirements for the signing of the Association Agreement.
As David Corbett, director of the Joint Support Office of the European Union for Nuclear Safety Support in Ukraine, Ukraine, said in a speech, the project began in Ukraine in 2011. Thanks to the system, all data comes to Kyiv, where the processing and decision-making process takes place. Back in September 2017, Ukrainian scientists with the help of this system were able to predict the distribution and determined the probable location of a source (in the Ural) of radionuclide ruthenium – 106 in the atmospheric air. The IAEA was informed promptly, which in turn informed all countries of Europe about the detection of ruthenium impurities.
According to him, over the entire period of cooperation with Ukraine, the EU has provided more than 1 billion euros to ensure nuclear and radiation safety. In particular, it concerns significant contributions to the construction of the NSC, ISF-2, the establishment of a system for alerting and responding at Radon corporation objects, as well as the provision of emergency brigades. In 2016, a Memorandum of Understanding was signed between Ukraine and the EU in this area, as well as outlined the next steps to be taken by 2020 within the framework of the «Instrument for Nuclear Safety Cooperation» (INSC) program.
«We are interested and support all the projects that are related to the fact that our licensees are equipped with modern response systems, because the most important thing is that the information is provided promptly and reliably. The system provides an exhaustive answer to all questions: from where, when, in what direction and in what way the radioactive sources of matter were transferred», – Tetiana Kutuzova, Head of the Emergency Preparedness and Radiation Protection Department of the State Nuclear Regulatory Inspection of Ukraine, said.
Scientists Wolfgang Raskop, Coordinator of the RODOS Development and Implementation Projects, Head of the Emergency Team at the Karlsruhe Technological Institute and Dmytro Trebushnyi, Software Development Coordinator of the System, said that the developers started their work immediately after the accident at the Chornobyl NPP. At the same time, there were several organizations that were studying the possibility of solving the problems associated with reacting during radiation accidents.
The RODOS system was the result of the joint work of several organizations. The latest development has added options for responding during forest fires in contaminated areas, floods or tornadoes, – developers of the system report.
According to Serhii Honcharov, Chief of the Department of Information Technology of SSE «Сhornobyl NPP», six years ago ChNPP also installed this system. The system was tested and well-proven during the fire, which arose on June 5 near the ChNPP. It is also planned to develop additional emergency response scenarios with RODOS during the operation of the NSC, ISF-2, ISF-1, or transportation of spent nuclear fuel.
