Robot pulled from Fukushima reactor due to radiation

A remote-controlled cleaning robot sent into a damaged reactor at Japan's Fukushima nuclear plant had to be removed 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 fuller examination to assess damage to the structure and its fuel. In this image released by Tokyo Electric Power Co. (TEPCO), a remote-controlled'cleaning' robot, bottom, enters the reactor containment chamber of Unit 2 for inspection and cleaning. The'cleaning' robot that entered one of three tsunami-wrecked Fukushima reactor containment chambers was withdrawn before completing its mission due to glitches most likely caused by high radiation The robot went only part way into a space under the core that TEPCO wants to inspect closely.
