This video from Japan says about itself:
3 February 2017
Radiation inside the containment vessel of the No. 2 reactor at the Fukushima No. 1 nuclear plant measures as high as a deadly 530 sieverts per hour, the highest since the 2011 disaster, plant operator Tokyo Electric Power Co. (TEPCO) announced on Feb. 2.
TEPCO calculated the radiation dose from video noise on footage it took inside the containment vessel in late January, when a camera was inserted to examine conditions inside and scout a route for a scorpion-like observation robot scheduled to go into the vessel later this month.
Deployment of the robot is also being reconsidered after two gaping holes were found along the robot’s planned path over a 5-meter-wide circular walkway inside the containment vessel, close to where the 530-sievert radiation dose was detected.
The holes in the metal grate walkway — one of unknown size and the other measuring about 1 meter square — make both routes considered for the robot impassable.
Six years after Fukushima, much of Japan has lost faith in nuclear power … Six years have passed since the Fukushima nuclear disaster on March 11, 2011, but Japan is still dealing with its impacts. Decommissioning the damaged Fukushima Daiichi nuclear plant poses unprecedented technical challenges. More than 100,000 people were evacuated but only about 13 percent have returned home, although the government has announced that it is safe to return to some evacuation zones: here.
Asking the tough questions on Fukushima — The Japan Times.
From the Asia Times:
Six years after Japan’s Fukushima nuclear accident three global nuclear corporations are fighting for their very survival.
The bankruptcy filing by Westinghouse Electric Co. and its parent company Toshiba Corp. preparing to post losses of ¥1 trillion (US$9 billion), is a defining moment in the global decline of the nuclear power industry.
However, whereas the final financial meltdown of Westinghouse and Toshiba will likely be measured in a few tens of billions of dollars, those losses are but a fraction of what Tokyo Electric Power Co. (Tepco) is looking at as a result of the Fukushima nuclear disaster.
