![]() In total, the whole decommissioning process is not expected to be finished until 30 to 40 years from now. As it stands, the plan is to dump some of this contaminated water in the Pacific Ocean, although this idea has kicked up a storm of controversies. Some of the efforts will be geared towards the removal of this physical nuclear debris, but they also have the problem of dealing with the highly radioactive waters that flooded the power plant. TEPCO, together with the International Research Institute for Nuclear Decommissioning (IRID) and Hitachi-GE Nuclear Energy, is tasked with clearing up and "decommissioning" the power plant. The camera also managed to capture some snaps of nuclear fuel that melted and fell to the bottom of the damaged reactor. With the help of the robot submarine's camera, the team installed special guide rings around the building, which will help steer the path for future probes. Bird's-eye view of the pedestal opening.

A worse-case scenario involves a full meltdown, when the core melts and falls to the bottom of the reactors containment vessel This could result in a large. 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. The recent tragic events in Japan have brought the issue of nuclear energy to the forefront of public discussion. Robots are used to this job because levels of radiation in the depths of the plant are too dangerous for humans. Nuclear safety: Reactors that can’t meltdown. Eventually, this melting slurry of radioactive fuel and equipment cooled down and solidified into the radioactive debris that the engineers are currently figuring out how to remove. The tsunami knocked down the power sources and cooling systems used to control the temperature of the fuel, which resulted in a colossal amount of heat to melt the fuel and the reactor. When the catastrophe struck, Units 1, 2, and 3 were busy working and had fuel in their reactors. Due to the harmful radioactive isotopes that were spewed into the surrounding environment, nearly 160,000 residents were promptly evacuated and Japanese authorities implemented a 30-kilometer (over 18 miles) exclusion zone around the power plant. After being struck by an earthquake and a 15-meter (49-foot) tsunami, three reactors at the Fukushima Daiichi nuclear power plant in northeastern Japan suffered catastrophic meltdowns, in what became the most severe nuclear disaster since the 1986 Chernobyl event. The Fukushima nuclear disaster unfolded on March 11, 2011.
