So, I ended up on a hunt for just what happened at Reactor number 3 and there is a lot of evidence to suggest that the damn thing actually blew up. There is some stories that it was due to an externally planted device, but there is a better case to be made for the total failure of all cooling, a lack of batteries for valve operation (they evidently had a cubic butt ton of 2V batteries when they needed 12V) but when you look at the videos of the explosion, there was definitely large pieces of something flying in the air and three distinct explosions. The claims I have found that seem most likely was that the core melted, and then mixing with steam allowed for a low order nuclear detonation to occur. Now, the really bad part, that no one seemed to want to mention: There was a spent rod pool ON TOP of the reactor vessel, which means that went up too, with a full load of MOX (mixed uranium/plutonium roods) that became pulverised, particulated, and pieces are said to have been found up to 3 miles away. Look at the videos and you can see several large pieces falling, and, bad for us, a huge plume of mixed radioactive material now airborne. If you go look at the pictures of Reactor three, I cannot see a reactor, the 3rd and 4th stories where the top of it should be sting up are caved in, when, if it was intact, it would be a thing sticking up out of the mess about 24 feet high. Yet everyone, Tepco, US, NRC, all say it was only a hydrogen explosion. So, would our government deliberately cover up something this severe? The stories of radioactivity didn't seem to match the event, but now I am not so sure.....
