Description

Based on the design structure and manufacture techniques of CRDM (Control Rod Drive Mechanism) nozzle, this paper analyzes and determines the root causes for the changes of inside diameter and perpendicularity for CRDM nozzle in terms of weld structure design, characteristics of stainless steel, design strength and implementation of pressure tests of the nozzle, and proposes the measures to control the key parameters.
