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.

Robots are used to this job because levels of radiation in the depths of the plant are too dangerous for humans. The plan is to eventually remove this radioactive debris, but the team is currently just surveying the size of the melted debris and analyzing the isotopes being emitted. The aim of the latest mission was to gain information about Unit 1’s primary containment vessel, as well as locate the tons of melted nuclear fuel debris that still lies in the submerged highly radioactive waters.

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.
