Fukushima cleaning robot pulled from reactor after camera gets damaged by massive radiation levels inside tsunami disaster site

The robot was the first to enter the chamber inside the No. 2 reactor since the Fukushima Da-ichi nuclear plant was badly damaged in March 2011


A cleaning robot at Fukushima nuclear power plant has had to be pulled out before completing its mission after its camera experienced glitches.

It’s believed the high-tech device was affected by high radiation as it examined the inside of the No. 2 reactor, one of three that suffered a meltdown in the combined 2011 Japanese earthquake and tsunami.

Tokyo Electric Power Company Holdings (Tepco) said it sent a robot with a high-pressure water nozzle into the prime containment vessel, which houses the pressure vessel, but had to bring it back out today after the robot’s camera went dark.

During its mission the robot was set to remove deposits as thick as 2 cm, believed to be the melted remains of paint and cable coating, from along a 7-meter-long rail leading to an area beneath the pressure vessel, which holds the core.

Even though the camera was designed to withstand 1,000 sieverts of cumulative exposure, Tepco said it believes it was affected by the high radiation.

The plant’s manager told Japan Times it estimated that the radiation in the primary containment vessel was as high as 530 sieverts per hour, during a similar probe late last month.

But other supposed experts have claimed it is much higher. (Click to Article)
