A variant of the model of thermogasdynamic and radiation state of the NSC has been developed to assess the leakage of unorganized air flows outside the NSC through leaks of the NSC itself and building structures under its walls into the environment along with organized flows through exhaust ventilation units of the main volume of the NSC depending on the directions and speed of the wind. CFD development of three-dimensional CFD models for analysis and prediction of thermogasdynamic and humidity conditions of tunnels of the service connecting branch (MTR) of KP “Kiev Metro”. The adequacy of the model was ensured by using experimental data on microclimate parameters in tunnels for 2018. The refined model made it possible to find the best ways to reduce humidity in the CCA using optimal control of the CCO ventilation system. Long-term cooperation agreements were concluded between the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine and the Chernobyl NPP, as well as the Kyiv Metro KP for scientific and technical support in solving urgent problems when using these lenses under normal and extreme operating conditions.
