“Digital twins” of objects and tasks solved during decommissioning of NPPs

The high complexity of the technological processes of decommissioning NPPs, the constantly increasing dynamics of work, many factors affecting their quality, as well as significant losses if the parameters of the technological process for dismantling and disposing of structural components of a power unit are not optimized, determine a promising way to solve this problem by simulating various options for performing practical work.
The use of “digital twins” for the design and optimization of NPPs decommissioning is the main method of solving this problem. In combination with other technologies such as artificial intelligence, it can significantly improve the efficiency of the integrated decommissioning process of NPPs.
The analysis of the possibilities of methods for the formation of “digital twins” for decommissioning NPPs is considered. An approach to solving urgent problem of a comprehensive assessment of the quality of work on decommissioning NPPs according to the criteria of their safety, environmental acceptability and economic feasibility is proposed.
