TEPCO spokesperson Kenichi Takahara said the piles of debris rose from the bottom of the container, including some inside the pedestal - a structure directly beneath the core - suggesting the mounds were melted fuel that fell in the area. be melted nuclear fuel covering the floor of a damaged reactor at Japans. The robot, carrying several tiny cameras, obtained the internal images of the reactor’s primary containment vessel while on a mission to establish a path for subsequent probes, TEPCO said. Its removal is a daunting task that officials say will take 30-40 years.

The nuclear disaster at Fukushima Daiichi was a much more severe meltdown. While radical environmentalists have exploited the issue to advance anti-nuclear policies, others have tried to defend this important energy source on the grounds of its importance to. Edge talked to reactor inspectors, Fukushima residents and nuclear scientists in the Japanese government to piece together Inside Japan's Nuclear Meltdown, which premieres at 10 p.m. The fuel did not manage to melt through the bottom of the reactor pressure. The recent tragic events in Japan have brought the issue of nuclear energy to the forefront of public discussion. Most of their highly radioactive fuel fell to the bottom of their containment vessels, making its removal extremely difficult.Ī previous attempt to send a small robot with cameras into the Unit 1 reactor failed, but images captured this week by a ROV-A robot show broken structures, pipes and mounds of what appears to be melted fuel and other debris submerged in cooling water, plant operator Tokyo Electric Power Company Holdings said Thursday.Ībout 900 tons of melted nuclear fuel remain inside the plant’s three damaged reactors, including about 280 tons in Unit 1.

Please look at the time stamp on the story to see when it was last updated. A: A nuclear reactor-core meltdown implies that the reactor-core initially composed of solid nuclear fuel rods has become molten because of overheating due to the loss of adequate cooling. The cleanup is ongoing and has been problematic, with power failures and leaks of contaminated water. This is an archived article and the information in the article may be outdated. It also triggered the meltdown of reactors at Japan's Fukushima Daiichi nuclear plant.
