Nuclear power plants (Pressurized Water Reactors) under construction at Kudankulm, India
This robot is used for testing the eddy current of steam generator tubes inside nuclear power plants. This task has been traditionally carried out manually and was considered hazardous due to the highly-radioactive atmosphere
New Delhi — Indian scientists have developed a breakthrough technology for a radioactive environment which will replace the human intervention for testing the eddy current inside nuclear power plants.
The robot manipulator was developed by scientists from the Center for Artificial Intelligence and Robotics (CAIR), Bengaluru, the state-owned Defense Research and Development Organization’s (DRDO) premier research laboratory. Last month the DRDO transferred the technology to the Nuclear Power Corporation of India Limited (NPCIL).
“The ECT Robot Manipulator system is a remotely controlled 5 Degree of Freedom (5-DoF) robotic system used for positioning the ECT probe below the steam generator tube, which has to be inspected. The system has been designed with a unique 2 DOF base for automatic calibration. The probe holder is equipped with a camera for automatic visual position correction to compensate for mechanical errors in the system,” DRDO said in a statement.
