Abstract

Abstract

To ensure the reliability and safety of the screw connection in reactor operation, the screw tightening torque of CPR1000 internals is as a start for the study. The step and method for replacing the inch screw by meter screw in the transformation design of CPR1000 internals is discussed, and screw structural elements which have influence on screw tightening torque are given in this paper.
