Moderator Heat exchanger crack detection System

The front view of the moderator Heat exchanger system is shown in the picture.
The XY Table along with eddy current probe used for detection is shown.
I completed this system along with my team members Mr. Biju TK, Dr Amar Banerjee, Mr. D Venkatesh in the year 2001.

MODERATOR HEAT EXCHANGER INSPECTION SYSTEM, PROJECT FOR NPC-NAPP, NARORA, INDIA

The project involves detection of cracks in the Moderator tubes of the nuclear reactor with the help of an Eddy current probe mounted on XY frame. The probe is moved to a desired position with the help of DC motors attached to each frame.

Responsibility: Building up the complete system, remotely controlled. The work involved the overall control system testing, modifying the permanent magnet DC motor PD controller cards, interfacing and programming PC add-on cards like Data acquisition card, timer card, I/O cards and developing algorithms & software for the overall control of the system.
