Abstract

Abstract

The heat transfer tube plug of steam generator (SG) in nuclear power plant is a common component to maintain the heat transfer tube. Two-dimensional axisymmetric model elastic-plastic analysis was used to simulate the plugging process. The influence and sensitivity analysis of seven parameters (stretching distance, friction coefficient between expander and plug, inclination of plug inner wall and expansion block, tooth width, tooth height, groove width, and expander length) on the tension rod force, expansion block contact force and maximum contact force during plugging process were studied, and the prediction formula for the sensitivity change of each parameter to the plugging process was obtained. The sensitivity effect engineering estimation formula of all sensitivity parameters on the plug plugging process was established. The research results can provide reference for the structural design of SG heat transfer tube plug.
