After almost three years since the start of the nuclear accident on March 11, 2011, cleanup efforts continue extremely slowly (and probably manually by human workers). Here are some before-and-after photos taken by TEPCO, but most of them are close-ups. You do not get much sense of how the plant has been de-cluttered overall (if at all).
The area photographed is between the ocean side of the turbine buildings and the embankment along the plant harbor. Radiation levels remain high here. Hoses and pipes that transport water run amid the debris.
From TEPCO's photos and videos library, 1/30/2014 (more photos at the link):
TEPCO had a chance to clear the site in March 2011, when large SDF tanks fitted with "dozer armour" (plate to push out debris) were sent to the plant. (See my March 20, 2011 post.) But the tanks were never used. Why? Because TEPCO had already had workers lay electric cables over the debris in their haste to restore the power to the plant, and they couldn't remove the debris without damaging the cables.
