TEPCO released more photos of the Reactor 2 Torus Room taken by the robot "Survey Runner" on April 18.
As I posted yesterday, about 90% of the circumference of the torus was covered by the robot, instead of about 1/3 to 1/2 that TEPCO had anticipated.
It looks dry for the most part, but the robot did see the water (the 7th photo).
