High Radiation Levels Continue at Damaged Reactors
On March 11, 2019, we commemorate the 8th anniversary of the Fukushima nuclear disaster. To an outside observer, this anniversary passes as a technical progress report, a look at new robot, or a short story on how lives there are slowly returning to normal.
Yet in Japan, the government has not figured out how to touch or test the irradiated cores in the three crippled reactors, which continue to contaminate water around the site of the melt down. The government does not know where it will put that radioactive material once it can find a way to move it. Meanwhile, the government and site operator are running out of room to store the contaminated water, which is filling up more and more tanks. The cleanup is estimated to take forty years and the cost is estimated at $195 billion.
The latest publicly released findings of radiation levels are from 2017, when Tokyo Electric Power Company had to use a remote-controlled robot to detect the levels in Reactor 2, since no human can approach the crippled reactor. The rates read 530 sieverts per hour, the highest since the March 2011 meltdown. We have no reason to believe that they have fallen since then. Remote-control robots are being used in the other reactors as well, indicating that radiation levels are similarly high there. Even using the robot, work can only be carried out for very short times, since the robots can only stand 1000 sieverts of exposure – less than two hours in this case.… Continue reading
