Shape-Shifting Robot Sent Inside Crippled Fukushima Reactor

For the first time, a robot entered the highly radioactive primary containment vessel (PCV) of Reactor 1 at the Fukushima Daiichi nuclear plant on Friday, in order to investigate the state of its dangerous and damaged interior, plant operator Tokyo Electric Power Co. (TEPCO) has said.

The plant was heavily damaged by the 2011 earthquake and subsequent tsunami that devastated northern Japan. Determining the state of the uranium fuel that powered the station is key to dismantling of the plant, a process expected to take decades.
