MHI’s robot proves nuclear decontamination work at Fukushima Daiichi

Mitsubishi Heavy Industries began demonstration work of its MEISTeR remote controlled robot at the Fukushima Daiichi nuclear power plant in Japan.

MEISTeR – or Maintenance Equipment Integrated System of Telecontrol Robot – finished demonstration testing of decontamination work and concrete core sampling at the plant, which is operated by Tokyo Electric Power Co. (TEPCO). The robot was developed to perform maintenance, repair and other works at disaster or severe accident sites.

The robot performed demonstration testing of two decontamination processes for the last month inside Unit 1. One process sucks up radioactive material through a nozzle, while the other uses a jet of abrasive blast material to scrape off a thin layer of a contaminated surface.

MHI plans to develop more robots to meet the diverse needs of the Fukushima plant and others.
