Abstract
The aspects of evaluating cyclical durability of screw joints are considered by the example of the main joint of the VVER-1000 nuclear reactor with a given record of operating load. Four variants of design are presented. The nonconservative essence of case three is noted. In the fourth case, the refined design requires additional in-service steps to guarantee the cyclic durability of the main joint pins.
