Robot pulled from Fukushima reactor

A cleaning robot sent into a damaged reactor at Japan's Fukushima nuclear plant had to be removed on Thursday before it completed its work because of camera problems most likely caused by high radiation levels.

It was the first time a robot has entered the chamber inside the Unit 2 reactor since a March 2011 earthquake and tsunami critically damaged the Fukushima Da-ichi nuclear plant.

Tokyo Electric Power Co said it was trying to inspect and clean a passage before another robot does a more thorough assessment of damage to the structure and its fuel.
