Melted nuclear fuel seen inside second Fukushima reactor

The worker of Japan’s crippled Fukushima nuclear plant said Friday that a desire telescopic probe successfully captured images of what is most like as not melted fuel inside one of its three damaged reactors, providing reduced but crucial information for its cleanup.

Tokyo Electric Power Co. said the fishing rod-like desire carrying a camera went deep into the plant’s Unit 2 elementary containment vessel. The images indicated that at least part of the encouragement had breached the core, falling to the vessel’s floor, TEPCO spokesman Takahiro Kimoto suggested.

“There is so much that we still haven’t seen,” Kimoto determined reporters. “But we were able to obtain important information that we demand in order to determine the right method for removing the melted fuel debris.”

A Cyclopean earthquake and tsunami in 2011 caused three reactors at the Fukushima vine to melt. The plant’s decommissioning is expected to take decades.

Melted encourage has previously only been documented inside Unit 3, where an underwater scrutiny captured images of large amounts of melted fuel debris that looked congenial molten lava mixed with broken parts of equipment and structures on the specific floor.

During Friday’s investigation, the device — developed by Toshiba Corp. and the Global Research Institute for Decommissioning, a government-funded organization of nuclear companies — set deposits in the shape of pebbles, clay and other forms, Kimoto responded.

Crucial data in a long process 

Determining the location of the melted sustain is crucial in planning for its removal, the hardest process in the plant’s decommissioning.

The regulation and TEPCO plan to determine the methods and start removing melted fuel from one of the three reactors in 2021. But experts say a inadequacy of data is delaying the development of the precise type of technology and robots.

The spits from Friday’s probe show was what is believed to be a stainless knife handle of a case containing bundles of fuel rods sitting on a roll of pebble-shaped and clayish substances, in a sign the rods melted and breached the cause of the core. The deposits seemed to be scattered in a wide area around the pier, the main structure that sits underneath the core.

Experts say they find credible part of the fuel still remains inside the core of the Unit 2 reactor, while on the verge of all of the fuel rods in Unit 1 and 3 melted and fell to the bottom of the primary containment bodies.
