Popis: Changes in the design of critical critical from the point of view of safety of the nodes of the main circulation pumps of nuclear power units and the corresponding dynamics of the accompanying thermo-hydraulic problems caused by these changes are analyzed. Attention is drawn to the insufficiently studied complex thermophysical processes occurring in tribological pairs of mechanical shaft sealing and sliding bearings, where the normal friction and lubrication conditions can latently go to pre-emergency and insufficiently controlled by existing monitoring systems technical conditions.
