On Wednesday TEPCO sent 6 workers into Fukushima Daiichi Units 2 and 3 to inspect the areas around the suppression chamber for the first time. Pipes littered the ground, and workers were careful to measure the radiation levels prior to entering a new area inside the wrecked building. The lower levels were confirmed to still be flooded with contaminated radioactive water, which is having a visible effect on the metal stairs and railing.
In Reactor 3, workers were thwarted by a door which has been bent and is now wedged in frame and cannot be opened. The maximum radiation outside the door was 75 millisieverts per hour.
