(TOKYO) — An underwater robot entered a badly damaged reactor at Japan’s crippled Fukushima nuclear plant Wednesday, capturing images of the harsh impact of its meltdown, including key structures that were torn and knocked out of place.
Plant operator Tokyo Electric Power Co. said the robot, nicknamed “the Little Sunfish,” successfully completed the day’s work inside the primary containment vessel of the Unit 3 reactor at Fukushima, which was destroyed by a massive March 2011 earthquake and tsunami.
TEPCO spokesman Takahiro Kimoto praised the work, saying the robot captured views of the underwater damage that had not been previously seen. However, the images contained no obvious sign of the melted nuclear fuel that researchers hope to locate, he said.
The robot was left inside the reactor near a structure called the pedestal, and is expected to go deeper inside for a fuller investigation Friday in hopes of finding the melted fuel.
“The damage to the structures was caused by the melted fuel or its heat,” Kimoto told a late-night news conference held nine hours after the probe ended its exploration earlier in the day.
