as declared in At least seven robots have been deployed at the Fukushima Daiichi nuclear generating station to assess damage within the three units on site that suffered meltdown events in March 2011.
Besides the smaller, data-collecting robots, Hitachi-GE Nuclear Energy and Mitsubishi Heavy Industries have each designed larger robots designed to do the heavy lifting and breaking down of material that needs to be removed from inaccessible areas.
Scorpion robots have been designed to fold in half, like a scorpion lifting its tail, to point a light and a camera forward.
The robot Little Sunfish is boxy in shape and has propellers for a tail.
All seven have collected some data en route to the reactor cores in which they were deployed.
Robot Little Sunfish ready to inspect Fukushima Daiichi 3 vessel
referring to An underwater robot has been developed to inspect the flooded primary containment vessel (PCV) of unit 3 at the damaged Fukushima Daiichi nuclear power plant in Japan.
In February, Tepco sent a “scorpion-shaped” Little Sunfish – also developed jointly by Toshiba and IRID – into the PCV of Fukushima Daiichi unit 2.
The following month, Tepco carried out an investigation of the PCV of unit 1 at Fukushima Daiichi using the PMORPH robot developed by Hitachi-GE Nuclear Energy and IRID.
The screw-driven submersible robot developed by Toshiba and IRID is 30cm long and has a diameter of just 13cm, enabling it to be inserted through the PCV penetration hole.
Goro Yanase, general manager of Toshiba Corporation’s nuclear energy systems and services division, said: “We have already developed remotely operated robots for inspections at Fukushima.
In Brief Toshiba has developed a robot to help survey highly radioactive waters at the site of the Fukushima nuclear power plant which named is Little Sunfish
The 2011 meltdown of the Fukushima Da-Ichi nuclear power plant was a disaster of outrageous proportions.
The robot will help find lost fuel rods and gauge the structural integrity of the facility to ensure safe removal.
Tokyo Electric Power Co (Tepco) has made progress in the removal of some of the spent fuel rods, but some melted fuel rods have managed to evade detection.
The cleanup effort is ongoing and has been employing robots to help remove the radioactive fuel still trapped within the ruins of the facility.
