Rust or peeling paint on a steel floor was visible in video footage taken by the second robot probe sent into one of the reactors at the crippled Fukushima No. 1 nuclear plant.
Tokyo Electric Power Co., operator of the plant, released the footage on April 17, two days after the robot entered the containment vessel of the No. 1 reactor.
The robot’s camera captured the water surface at the bottom of the containment vessel. Light from the robot can be seen reflecting off the water surface estimated at between 30 and 110 centimeters below the steel gird floor.
The footage did not show damage to equipment or fallen objects.
The first robot became immobilized hours after it was sent into the containment vessel on April 10. Efforts to retrieve that robot were abandoned, but
High radiation levels have prevented workers from going near the containment vessel.
