Establishment of the Industrial facility for purification of water and liquid radioactive waste of ChNPP from transuranium elements (TUE) and organics – Phase I


The Project is funded by the European Union under the Program “Instrument for Nuclear Safety Cooperation 2011. Part II”.

Objective of the Project:

The common objective of the Project, a part of which is the Services Contract No.NSI/2014/348-291 dated 01.09.2014, is to establish the industrial facility for purification of the Shelter water and ChNPP liquid radioactive waste from dust-suppressing compound emulsions to the levels enabling to treat these wastes in the future at the Liquid Radioactive Waste Treatment Plant (LRTP) and also to reduce concentration of transuranium elements to the levels enabling to perform near-surface disposal of final product from the LRTP.

Implementation stages:

- Development of design documentation (including complete set of safety-based documents) of the industrial-scale facility for removal of TUE and DSC emulsion from water coming from the Shelter Object and from evaporator concentrate (hereafter, industrial purification facility);
- Assistance during expert review of the design documentation;
- Development of technical and tender documentation for delivery and assembling of the industrial purification facility;
- Development of conceptual design for secondary radioactive waste management.

The following Project results were achieved:

The Design of an industrial facility for purification ChNPP’s water and liquid radioactive waste from transuranic elements (TUE) and organic compounds (IPF LRW), including the Safety Analysis Report (SAR), were developed.

Based on the expert report of CS "Ukrgosstroiekspertiza" dated December 16, 2016 No. 00-1147-16 / 13, the IPF LRW Design was approved by SSE ChNPP Decree No. 57, dated January 26, 2017.

The Expert Report of the State Expertise of Nuclear and Radiation Safety of IPF LRW Design and SAR was obtained. According to the State Expertise conclusion, the main design decisions generally meet the Nuclear and Radiation Safety requirements.

The Detailed Technical specification for the Project Phase II implementation and Tender dossier were developed and agreed.

The Conceptual Design for the IPF LRW secondary waste processing was developed and agreed.

Impact of the project:

Implementation of the project as a whole will have a positive impact on improvement of the safety and cost-effectiveness of Radioactive Waste Management at the Chernobyl NPP and, in particular, radioactive waste minimization.

The IPF LRW creation will allow further processing of the drainage water and liquid radioactive waste at the LRTP, and to reduce TUE concentration to the levels allowing the LRTP final product near-surface storage.

Implementation of the Project as a whole in the long term is one of the elements of the "National program of ChNPP decommissioning and Shelter object transformation into ecologically safe system".
