YOKOHAMA, Japan – A new robot that raises its tail like a scorpion is scheduled to look at melted nuclear fuel inside one of the three wrecked reactors in Japan.
Toshiba Corp. is co-developer of the "scorpion" crawler that was demonstrated Tuesday. The company says the robot will venture into Unit 2 reactor's primary containment vessel in August.
Officials hope the robot can get a glimpse of fuel in the pressure vessel in the middle. The fuel hasn't been located exactly and studied because of the fatally high radiation levels nearby.
The difficult work of decommissioning the Fukushima plant damaged by the 2011 earthquake and tsunami will take decades.
