According to this latest video from nuke expert Arnie Gundersen, the nuclear fuel racks in Fukushima reactor #4 are exposed to air instead of being immersed in water, and that's not good.
"The fact that the nuclear fuel pool does not have water in it, to me, indicates that it might be a clean path for those heavy elements to be escaping from the building and being discovered off site."
