ISP NPP Scientists Participated in IAEA Mission
This three-days expert mission of the International Atomic Energy Agency at Chernobyl NPP, organized within the framework of the Technical Cooperation Project UKR9038 “Support to Nuclear Power Units decommissioning and Radioactive Waste Management at Chernobyl NPP site and within the Exclusion zone” was held on July, 24-26, 2018.
The purpose of the mission is to review the Feasibility Study for creation and location of new facilities for radioactively contaminated materials management on compliance with IAEA standards.
At the meeting leading specialists on decommissioning and radioactive waste management of ChNPP, the IAEA experts and the ISP NPP scientists discussed the necessity and problem issues concerning creation of new objects for radioactive waste management during NPP decommissioning.
Representatives of Chornobyl NPP informed about the preparations undertaken on decommissioning and radioactive waste management practices at Chernobyl Nuclear Power Plant, and presented conceptual decisions on the creation and location of additional facilities for radioactive contaminated materials and constructions management at ChNPP site.
The IAEA representatives, in their turn, shared their experience of the NPP decommissioning in Germany, gave valuable advices on solution of scientific and engineering problems that can appear at the decommissioning stage and define the priorities during the new facilities construction for the radioactive waste management.
Volodymyr Rudko, the Head of the Division, noted that during dismantling of unstable constructions and debris removal of the Shelter object radioactively contaminated metal and reinforced concrete structures, mixed radioactive waste and high-level waste will be generated. The analysis of accumulated volumes of radioactive materials and forecast of their further formation shows that the existing infrastructure capacity isn’t enough. In addition, the used technologies do not cover all types and categories of radioactive materials, do not allow for management and costs optimization. To solve these problems, the existing system of radioactive materials management should be improved by creating new facilities for its management.
Leonid Pavlovskyi, the Head of the Department, focused on the necessity of the preliminary assessment of feasibility of decontamination for separate types of radioactively contaminated materials based on the “dose-cost-benefit” analysis.
