Japan-based Mitsubishi has announced the accomplishments of its autonomous robot, which is used to carry out underwater inspections in a nuclear reactor vessel.
The A-UT – autonomous underwater inspection device – from the house of Mitsubishi Heavy Industries (MHI) Group is tasked with checking for faults in the weld lines inside a reactor vessel at the core of a nuclear power plant.
A nuclear reactor vessel, which is operational, is highly radioactive and also works under high temperatures and high pressure. Therefore, it is not feasible for a human to carry out regular inspections inside the reactor vessel.
The A-UT is fitted with a seven-axis robotic arm with sensor pads at the end, and is designed specifically to do this.
