Japan suffered the worst nuclear disaster in history in 2011. Robots and drones play a key role in the cleanup.
Nuclear power has understandably been a contentious issue in Japan since the 2011 Fukushima incident.
As contaminated water continues to leak from damaged nuclear reactors, cold is the latest line of defense.
The cleanup will take decades in places humans can't go. Robots will instead.
The ice wall is one way of keeping the massive amount of toxic water stored in the facility. But Japan has floated the idea of dumping it into the Pacific Ocean.
Here’s what it’s like inside the melted-down reactors of the Fukushima Daiichi Nuclear Power Plant.
Wild boar, foxes, raccoon dogs and rabbits appear to be thriving in a part of Japan where humans dare not live.
I get to try the Guardian GT big-arm robot, which is like a real-life Power Loader from Aliens. It's controlled by a human and has incredible precision, but it's also incredibly strong. Made by Sarcos Robotics, the GT can be used in situations that are too dangerous for humans to enter, like nuclear disarmament or decommissioning power plants.
The country's environmental minister says storage space is almost used up, so the contaminated water may end up in the Pacific.
