Japan Earthquake: Nuclear Plants at Fukushima Daiichi
Thanks for your response. The plant being built on a platform helps to explain the puzzle and I assume that must apply to all the buildings/plant to the west of the turbine buildings area. Many thanks.- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
Thanks for your response. Yes I've seen them. jlduh has clarified the lack of damage as apparently there'a large step in the site (not evident on the images I've seen published so far) somewhere near the turbine buildings that reduced the affect of the tsunami as that would mean it was much...- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
Thanks for your response. There's plenty of damage shown as the tsunami flowed over the constructions and surfaces (extending over about 100 metes) to the east of the long turbine generator buildings back to the breakwater/harbour/coast - that's evident from the satellite images. Maybe that...- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
Puzzling that there's plenty of damage as evidence of explosions and even possibly an earthquake but so far not much to say there's been tsunami water inside the main area of the site, that is the area to the west of the long turbine generator buildings and yet the tsunami is claimed to have...- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
I guess that the dirty dark brown wavy line on those cream coloured buildings in the background might be a tsunami tidemark (or it could be explosion dust or debris or something else but the wavy dark brown stuff doesn't seem to be that deep elsewhere - for example on the roofs behind) maybe...- Arcer

Another photo of 3 with steam from a slightly different angle. http://www.world-nuclear-news.org/uploadedImages/wnn/Images/Fukushima_Daiichi_3_March_2011.jpg and a general site layout http://www.lifeslittlemysteries.com/images/stories/fukushima-02.jpg is that the dry cask building or the...- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
http://www.youtube.com/user/KurtsFilmeVideo#p/u Speculation again but it's possible that those bits of roof (steel) still remaining on building 3 are actually being supported by the gantry crane. Although against that I remember there was opinion that the crane might have landed on a low level...- Arcer

Very interesting that units 4 and 2 had explosions withing 6 minutes of each other both on the 15 March.- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
At a rough count there seems to be about 30 to 40 of those rods scattered about which is about a full fuel rod assembly. Most of them seem to have fallen and come to rest as a loose bundle with the rods almost in parallel. That's as if they'd slid out together through a hole in the building...- Arcer

Japan Earthquake: Nuclear Plants at Fukushima Daiichi
I suppose it's possible that the plug to 3 had been temporarily removed (fully or partially over the opening) before the explosion for some reason. Possibly to help with the cooling or pressure release in some way or even for some form of maintenance or perhaps an urgent action in the knowledge...- Arcer

Do new fuel rods go straight into the reactor after inspection.- Arcer
