Technical Cooperation Project

 

The project is financed from IAEA Technical Cooperation fund and its budget can be varied or redistributed if necessary.

Project Objective:

Assistance in Chernobyl nuclear power plant (NPP) decommissioning and the Shelter object transformation into environmentally safe system, as well as creation of Comprehensive National Radioactive Waste Management Program and Action Plan.

Completion status:

Within the period 2016-2017, the project activity was focused on the crucial for ChNPP problems of Radwaste Management, particularly Liquid Radioactive Waste, radioactively contaminated water and ion-exchange resins and on supporting of the work implementation during the Chernobyl NPP Final shutdown and preservation stage. During the two years, 13 expert missions, workshops and meetings were organized in accordance with the agreed work plan, attended by more than 200 specialists, mainly from Chernobyl nuclear power plant, NPP Safety Problems Institute, SNRIU, SSR Institute “Chernobyl Center”, and others. 19 specialists took part in ten International conferences and workshops where they had the opportunity not only to study the existing best practices, but also to share ChNPP’s developments in field of decommissioning and Radioactive Waste Management.

The results obtained, their impact on the industry:

The work in field of RAW management is aimed on creation of an effective system for different types waste management at Chernobyl NPP. In particular, it is very important from the point of view of resource saving to select the technologies for salt water treatment without evaporation method. At present Chernobyl NPP uses an evaporation scheme for the radioactive waters purification, designed for the Unit in operation. It is necessary to select the technologies allowing an effective Chernobyl NPP radioactive waters processing using the other methods. After the technology selection it is necessary to perform pilot tests to confirm the effectiveness of the proposed technology and its suitability for use at ChNPP. During the project implementation, alternative purification methods were considered and technical specification for the pilot facility was developed. Work continuation is planned within the new project for 2018-2019.

Expert support is provided and further research is underway to select options for secondary waste management, obtained from the facility for RAW purification from transuranic elements (TUE). This is continuation of the activity launched in 2012-2015, within which a pilot facility for the liquid radioactive waste purification from transuranium elements and organics was created and technical specifications were developed, which were used as a basis for the industrial facility in the EC project U4.01/11C aimed on the industrial facility creation. Now work is under way to find solutions to manage a secondary waste from this facility.

Significant efforts within the project were aimed to support Chernobyl NPP decommissioning, in particular, expert assessment of the revised "ChNPP decommissioning program" in terms of compliance with IAEA recommendations, workshop for studying of successful international practices for reuse of territory and plans for Chernobyl NPP site and repurposing of existing buildings and facilities for industrial development in the field of radioactively contaminated materials, radioactive waste and SNF management. Developed by IAEA expert group proposals and recommendations for ChNPP plans will form the basis for Chornobyl NPP site industrial development optimization and its integration in the Ukrainian nuclear complex.
