Satellite imagery from March 16, 2011 @09:35am see R4 to the left (south) steaming from the south wall where the sfp (spent fuel pool) is located. R3 is steaming like a jet into the atmosphere centre pic most damaged reactor. Can see R1 on the right blown up and no steam as it would have already burned and released its lethal load to the environment.
Satellite imagery March 16, 2011 @ 10:35am Just like the picture before this one we can see R1 in red box at top (north) with no steam from its already melted fuel. R4 is at the bottom (south) in red box no steam seen from the north wall.
Satellite imagery March 17, 2011 @ 12:00am steam from all reactors dissipates compared to the first week of releases.
March 17, 2011 from helicopter TEPCO says/confirms there is water in R4sfp
March 18, 2011 fly over Zoom of molten mass that flowed out of R4 north wall the same side as the Equipment Pool (EP). The R4SFP in located on the south wall.
March 20,2011 heat signature from thermographic images show there was more to reactor 4 then the spent fuel pool. The SFP would be on the left and the core in the muddle and the equipment pool on the right all show heat signatures.
March 24, 2011 drone fly over of R4 facing west seeing east wall, red swing pump for pumping concrete used for pumping water on R4. See steam rising from centre of R4 building. see molten mass out of the north wall onto vent pipe (right side of building)
This is on top of R4 looking at the core containment well. Notice the black on the well wall past the far side of the workers that looks like a fire signature from burning fuel in this core.
This is the layout of R4 building floor plan compared with a the thermographic image of R4
There is no question I think, TEPCO and the nuclear industry are lying about Reactor 4. Is the SFP all burned up? I don't think it all is... but its defiantly damaged and defiantly lost some fuel. Pictures show steam so that means water and current 2013 images show intact fuel so it could not have gone completely dry as there would not be such intact fuel assemblies as we see now.
