Swedish Robotic Technology Used to Clean Fukushima Nuclear Plant

Husqvarna Construction’s remote-controlled demolition robots DXR 310 and DXR 140 are put into use in the rescue work at the Fukushima nuclear power plant. "In this environment, there are very high demands on machines and technique. We’re proud to have been chosen as a supplier," says Anders Ströby, head of Husqvarna Construction Products.

Husqvarna has sold two of the company’s top modern, remote-controlled demolition robots to Takenaka Construction, the company put in charge of the clean-up of the fourth reactor at the Fukushima nuclear power plant. At the plant an extensive resue work is still underway after the reactor’s failure in March this year. Robotic technology plays an important part in the work as radiation levels still are very high. The robots will be used in the heavy demolition work such as tearing down concrete constructions and dealing with contaminated materials.

"Our robots are well adapted to this environment. They are powerful, reliable and easy to manoeuvre, even in narrow spaces. They will perform important work at the plant for a long time to come," says Anders Ströby.

The demolition robots have been specially adapted to function optimally in the demanding environment. The bigger robot, DXR 310, has been provided with a video camera and transmission equipment to enable the operator to work from a safe distance from the reactor.

Husqvarna’s Japanese organisation has trained Takenaka Construction personnel in the use of the robots. The clean-up at Fukushima is expected to continue for many years.
