Digital twins of nuclear energy complexes

The complex task of integrating various information, calculation, and simulation tools into a single system can be implemented using digital twins capable of optimizing design, engineering, and technological solutions, as well as supporting the ongoing operation of facilities. This article presents the results obtained within the development of integrating projects for the facilities of the “Proryv” project area, as well as discussing tools and solutions for creating digital twins, including integral mathematical models as a computational representation of the facility. The main directions for the further possible development of digital twins are considered relative to the construction of facilities, support for their operation, replication of digital twins themselves, and the search for innovative solutions that contribute to improvements in the quality both of the digital twins themselves and the actual created facilities.
