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.

According to the Shanghai Daily:
Robots are being used to explore the site because the task would prove fatal for humans due to lethal levels of radioactivity.
“The radiation level is very high inside the PCV and we assume that the maximum time for investigation is five to six hours each time, though the robot can investigate for 10 hours,” Tomohisa Ito, a spokesman for the International Research Institute for Nuclear Decommissioning, told IDG News Service via email.
