The latest robot attempting to find the 600 tons of nuclear fuel, and debris that melted down
. . . 6 years ago in the wrecked Fukushima No. 1 nuclear power plant,
. . . met its end in less than a day.

After spending most of the time since the 2011 disaster,
. . . containing radiation, and limiting ground water contamination,
. . . scientists still don’t have all the information they need for a cleanup,
. . . that the government estimates will take:
. . . . . . 4 decades, and cost
. . . . . . ¥8 trillion.

It is not yet known if the fuel melted into,
. . . or through the containment vessel’s concrete floor, and
. . . determining the fuel’s radioactivity, and location,
. . . is crucial to inventing the technology needed to remove it.

3 reactors at the plant suffered meltdowns,  
. . . each poses different challenges, and
. . . requires a customized approach for locating, and removing the fuel.
