Tokyo (AFP) July 21, 2017
The operator of Japan's stricken Fukushima nuclear plant said Friday it is using an underwater robot in a renewed attempt to inspect damage suffered in a tsunami-induced meltdown.
A massive undersea earthquake on March 11, 2011 sent a huge wave barrelling into Japan's northeast coast, killing more than 18,500 people, and sending three reactors into meltdown at the plant in the worst such accident since Chernobyl in 1986.
Tokyo Electric Power Co (TEPCO) in February sent a remote-controlled robot into one of three damaged reactors where radiation levels have hit record highs.
But the mission was aborted at the No. 2 reactor after the robot could not reach its target destination beneath a pressure vessel through which nuclear fuel is believed to have melted as the robot had difficulty moving.
Locating the fuel debris is part of the decommissioning process for the plant expected to take decades.
On Wednesday, TEPCO sent a robot measuring 13 centimetres (5.1 inches) wide and 30 centimetres long to the No. 3 reactor and conducted another inspection on Friday, a spokesman said.
But the company has yet to find the fuel debris.
"Today the robot went deeper inside the containment vessel" of the reactor, he said, referring to the Friday probe, adding that TEPCO will analyse the images.
The Japanese government said in December that it expects total costs including compensation, decommissioning and decontamination to reach 21.5 trillion yen ($192.5 billion) in a process likely to take at least four decades as high radiation levels slow operations.

Finnish utility TVO on Thursday claimed another partial victory in arbitration in a bitter dispute with France's Areva over a troubled nuclear reactor, which the French side said was "disappointing". Areva, together with German engineering group Siemens, has been building in Finland since 2005 what is meant to be a showcase of next-generation nuclear power, but delays and cost overruns have ... read more
