Survey robot breaks down inside Fukushima No. 1 reactor in under three hours


A remote-controlled robot inserted to survey the inside of the No. 1 reactor at the damaged Fukushima No. 1 nuclear power plant has stopped functioning, Tokyo Electric Power Co. said.

As a first step in the utility’s effort to remove melted nuclear fuel from the bottom of the unit’s primary containment vessel, the shape-shifting robot was sent in Friday morning to find the exact location of the highly radioactive debris.

Set to cover some 20 meters of the first floor on the first day, the robot began its trip at around 11:20 a.m. but halted at around 2:10 p.m. after completing two-thirds of the route, Tepco said.

The utility said footage from the robot’s camera shows it passed an opening leading to the vessel’s basement, where the molten fuel is believed to have ended up after the core meltdowns occurred after the March 2011 quake and tsunami.

    I think the answer is to send down robots with scoops of concrete. After sending in several million, the reactor will be entombed. Then repeat the process for the others at the Fukushima Daiichi complex.

      Let’s spend untold millions of dollars doing something that is unnecessary simply because your irrational fears make you think we should do it.

    Why, is the queston.

    The Japanese people have come to terms with a threat so deadly it kills robots. And their leaders have not.

    I beg to know why a business would want to do this to there customers?

  • Not the first mechanical fatality in there. We need stronger robots if they are going to survive what we do to this planet in the course of developing them. Now, that may seem circular but that’s fate for you: bootstrapping.
