IV International Conference on Nuclear Decommissioning and Environment Recovery – Inudeco 2019

   The IV International Conference on Nuclear Decommissioning and Environment Recovery – INUDECO 2019 was held at the site of Chornobyl NPP and in Slavutych on April 24–26, 2019.

   The conference was organized by the State Specialized Enterprise «Chornobyl NPP», Slavutych City Administration, the Institute for Safety Problems of NPPs of the NAS of Ukraine and the Institute of Mathematical Machines and Systems Problems of the NAS of Ukraine.

   Specialists in nuclear industry as well as scientists in the field of radiation protection, radioactive waste management and radioecology participated in the conference. The main task of the conference was to consider practical issues on nuclear facilities decommissioning, radioactive waste and spent nuclear fuel management, as well as discussion of the results of researches, conducted at the Shelter object. The issues of further directions for the use of territories exposed to large-scale radioactive contamination were considered. The conference participants had the opportunity to review the experience of reintegrating the territories exposed to radioactive contamination in Japan, and to get acquainted with the activity on the creation of protected areas in certain parts of the Chornobyl Exclusion Zone.

   Scientists from France, Norway, Denmark, Spain and Japan as well as representatives of the State Agency of Ukraine on Exclusion Zone Management, specialists from the ISP NPP, Chornobyl, Zaporizhzhya, Rivne NPPs and others participated in the conference.

   Valeriy Seyda, First Deputy Director General of the SSE ChNPP, opened the conference Oleh Nasvit, First Deputy Head of the State Agency of Ukraine on Exclusion Zone Management, Yurii Fomichov, Mayor of Slavutych, Anatolii Nosovskyi, Director of the Institute for Safety Problems of NPP of NAS of Ukraine were key speakers of the conference.

   The issues of the Chornobyl NPP decommissioning, radioactive waste and spent nuclear fuel management were considered on the first day of the conference. A special place was given to the problems of scientific support of the Chornobyl NPP decommissioning. The report of Anatolii Nosovskyi, the Director of the ISP NPP, “Scientific and technical support of activities at the Chornobyl NPP site” was devoted to the problem of the current state and place of science in the works at the Chornobyl NPP. The report showed the main areas of scientific and technical support of NPPs decommissioning that should be developed currently.

   The scientists of the ISP NPP participated in the work of the breakout sessions:

• Chornobyl NPP and the Shelter object;
• Nuclear power and new energy;
• From catastrophe to a new life.

   The scientists of the ISP NPP in their reports provided information on the results of current research conducted at the industrial site of the Chornobyl NPP and on the territory of the Chornobyl Exclusion Zone. The reports were presented by:

• Evgen Vysotsky – “Nuclear Safety of the New Safe Confinement. Assessment of the Current and Predicted Level of Subcriticality of a Nuclear Hazardous Accumulation of Fuel-Containing Materials”;
• Roman Godun – “Investigation of the Dynamics of the Effective Multiplication Factor of Neutrons of FCM Clusters Located Inside the New Safe Confinement Complex”;
• Olexander Kalynovskyi – “Assessment of the Radiation Situation in the Surface Air Layer Near the Shelter Object during the Construction of a New Safe Confinement “Arch”;
• Yuri Morozov – “ChNPP Decommissioning. Problem Aspects of Dismantling/Amplification of Protruding Parts of the Machine Room and Deaerator Stand”;
• Mykola Panasyuk – “The Influence of “Arch” on Radiation Conditions in the Ground Waters of the ChNPP Industrial Site”;
• Serghii Stadnyk – “Prospects for Using an Expert Research System to Increase Effective Neutron Monitoring Inside the Shelter Object New Safe Confinement Complex”;
• Serhii Paskevych – “Assessment of the State of the Chornobyl NPP Cooling Pond as an Object with Potentially Dangerous Environmental Impacts” and “Modeling the Processes of Dismantling the Roof Elements of the Shelter Object and Estimating Personnel Exposure Doses Using Modern Software”;
• Anatolii Doroshenko – “The Monitoring System for Nuclear Safety of the Shelter Object New Safe Confinement Complex and the Analysis of its Effectiveness”;
• Mykola Talerko – “Development of Models and Computer Systems for Forecasting Atmospheric Radionuclide Transfer in Cases of Emergency Situations in the Chornobyl Exclusion Zone”.

   The discussions held during scientific presentations contributed to the exchange of experience and views on the obtained results and the development of further research directions.
