Japan is just getting started on tearing down its wrecked Fukushima Dai-Ichi nuclear power plant — a process that's expected to take 30 to 40 years, according to the plant's manager. Next year, it's going to tackle the decommissioning of reactor 3, which was damaged by a hydrogen explosion during the plant's meltdown in 2011. The only problem? Reactor 3 is currently filled with radiation that would be dangerous for any humans who walked inside. So rather than send in people for cleanup duty, Toshiba, the original builder of reactor 3, has created a robot to do the job instead. On Monday, Toshiba unveiled the large remote-controlled machine, which boasts two crane-like arms that will remove bundles of fuel rods from the cooling pool inside reactor 3. One arm helps to pick up and cut the rods, while the other arm holds them steady. The robot is slated to extract 566 of these fuel rod bundles — known as assemblies — from the reactor starting sometime in 2017. The machine is also equipped
