The high radioactivity in Fukushima leaves to “survive” not the robots

The radiation in the Fukushima nuclear power station is proving so high that… you don’t “survive” or robots which have been mobilized in the areas where exposure to radiation is dangerous for human beings, after the nuclear disaster caused by the earthquake and tsunami in March 2011.
“The access to the interior of the nuclear power station is extremely difficult. The biggest obstacle is the radiation,” said Ναοχίρο Μασούντα, head of decommissioning for the owner of the company TEPCO, adding that it required two years to develop a robot.
From the moment the robot, designed by Toshiba and are coated with chrome, closing the reactor 3, and their circuits are destroyed by radiation.
The robots are designed to enter the tanks where the radioactive fuel rods and recover.
The robot is not able to enter the reactor 3 due to the accumulated levels of radiation in comparison with the less radioactive reactor 4, where 1.535 fuel rods have already been removed.
In the past TEPCO have been criticized for the equipment used for the recording of the radiation, which had a limit of 100mSv while the radiation was in fact 18 times higher.
Officials now claim that the radiation levels in many locations in the area have been dramatically reduced.
More than 8,000 workers are still working daily for the decommissioning of reactors and the cleaning of the space.
The water injected into the reactors to cool, stored in tanks, and so far, the Japanese fishermen refuse to allow the release of the sea.
However, the tanks run anyway the risk of leakage of radioactive water into the sea.
TEPCO is now developing another model of robot that will be ready in 2017 and it is believed that it will have more success in the approach to the reactor 3.
