In July, a meeting of the General Assembly of the European Technical Safety Organisations Network (ETSON) took place in Prague (Czech Republic). The State Scientific and Technical Center for Nuclear and Radiation Safety (SSTC NRS) was represented by Oleksandr Pecherytsia, Deputy Director on Scientific and International Activities, Yuliia Yesypenko, Head of International Projects Department, and Yuliya Balashevska, Head of Emergency Preparedness and Radiation Monitoring Department.
Within the implementation of the ETSON Development Strategy, representatives of the European Commission, IAEA and Western European Nuclear Regulators Association (WENRA) were invited to participate in General Assembly meeting.
During the meeting, the participants discussed the signed Memoranda of Cooperation with JRC and IAEA, considered promising areas to intensify cooperation with the specified organizations. Besides, a number of other important issues were addressed, in particular on the preparation for the participation and conduct of the EUROSAFE 2019 Forum to be held in Cologne (Germany) and ETSON Summer School to be carried out in Ukraine in 2020.
During the General Assembly, the participants were provided with an opportunity to familiarize with the experimental facilities of the Research Center in Řež (Centrum výzkumu Řež s.r.o.), in particular SCWL that is an experimental facility for studying the behavior of structural materials under supercritical conditions (at a temperature of 6000С and pressure of 25 MPa), LOCA facility for modeling of loss-of-coolant accidents and HTHL that in experimental facility for the simulation of chemical processes in generation IV reactors with gas coolant.
SSTC NRS representatives provided the participants with the BARCO project proposal (Benchmarking on Assessment of Radiological Consequences), the initiative of which was first announced during a meeting of ETSON Expert Group on Emergency Preparedness and Response on 27 June 2019 (Paris, France) and approved by the profile experts. The project idea was to assess methodological approaches to modeling and technical capabilities of computer codes, which was supported by ETSON Board. Representatives of IRSN (France) and VUJE (Slovakia) offered a number of recommendations aimed at improving the benchmarking procedure, which were taken into account in developing the current revision of the project proposal.
Yuliya Balashevska explained that although benchmarking and emergency training envisage time constraints for participants, the main difference is that the first one does not require simultaneous involvement of all participants in the scenario calculations, which greatly simplifies and reduces the cost of the process. Based on the conditionally set emergency, participants will be able to carry out required calculations of radiological consequences for their countries and for Ukraine using the tools available for a limited but convenient period of time. Such a format will allow comparison of results of the participating countries and make conclusions on the reliability and accuracy of data.
“Our institution is actively involved in ETSON events. This makes it possible to interact and communicate with the technical support organizations of other countries, which has a positive impact on the level of providing scientific and technical support to the regulatory authority. Besides, our proposal to carry out ETSON Summer School in Ukraine was welcomed by the General Assembly, and we therefore hope that we will be able to participate in another interesting project. It is expected that the topic will directly relate to emergency preparedness”, Yuliia Yesypenko concluded.
