Tokyo Electric Power Co. (TEPCO) sent a robot to examine a reactor' containment vessel at the Fukushima Daiichi nuclear power plant, crippled in a 2011 incident dubbed the world's worst nuclear disaster since Chernobyl.
The remotely controlled device, equipped with cameras, a thermometer and a dosimeter, will allow the company to take a look inside the vessel containing one of the three reactors, which underwent a meltdown. Unlike people, the robot can withstand high levels of radiation.
Approximately 40 workers will be involved in the operation, the first of its kind. The first stage is expected to be completed on Friday. TEPCO will send the robot into the vessel again on Monday. The company's ultimate goal is to use the robot to inspect the melted fuel inside the vessel.
