摘要：

In-service inspection requirements of reactor internals of sodium-cooled fast reactors offer challenges in the design and successful deployment of carrier mechanisms. A single-carrier mechanism consisting of inter-connected rigid links having multiple ultrasonic transducers is envisaged for carrying out all the necessary inspections. The kinematic analysis of the chain assembly of the proposed carrier mechanism is the main focus of the present paper. Initially, a base design of the chain assembly was proposed and the same is analysed with respect to the linearity and smooth motion transmission. The kinematic chain of the base design was modified to improve the motion transmission characteristics. Parametric studies were done to fine-tune the design parameters of modified design. The analysis has given valuable insights into the performance of chain assembly and provided necessary data for the smooth operation of chain assembly.
