1. Fueling platform has been positively identified in the spent fuel pool, so it wasn't blown sky high into the turbine building. Not clear if this is the same thing spotted by Ian Goddard who saw something sticking out of the water that looks like a platform. These pictures show one of the feet.
2. Back in March 12 I found that they also have plans to drive a camera around fuel pool in unit 4, and they want to be able to put fuel into the still water-filled reactor core.

Here's the plan for fuel pool #4. They are going to drive a ROV underwater robot to inspect the fuel pool. The operator will be nearby on the floor.

This is how fukushima diary covered it - a big hunk of metal fell on the fuel, and that can't be good.

New and quite exciting photos from the spent fuel pool of unit 3
http://photo.tepco.co.jp/en/date/201...20413-01e.html Pictures are taken close to the cask transfer area, they show upright standing fuel racks, and .. a fine close up view of an end piece from the rail foot of the bridge that carried the fuel handling machine. (Here seen compared to a Quince photo of the foot of the quite similar FHM bridge of unit 2  |

35 tones of refueling machine on fuel storage rack in reactor 3
Posted by Mochizuki on April 13th, 2012 · 1 Comment
35 tones of refueling machine was found dropped over the fuel storage rack in reactor3, Tepco announced in their press conference of 4/13/2012.
They assume it dropped when reactor 3 had the explosion.
They watched it with a remote controlling camera operated by earthquake-resisting control room.
Tepco only published 4 pictures, which are too dark and not clear for today.
The 35 tones of refueling machine is planned to be taken out in the end of 2014.
According to Tepco, the size of pool is 12.2×9.9×11.8ｍ, the machine is 14m. There are 514 assemblies of spent fuel and 52 of new fuel in the pool. (566 assemblies in total)
When it dropped, it damaged the pool as well. From the analysis result of water in the pool, Tepco assumes the fuel is not severely damaged.
They still haven’t checked if the machine lies on the bottom of the pool.
Now somebody pointed out the ladder that was on the platform:
