This week, Dr. Caldicott has a new conversation with nuclear engineer Arnold Gundersen about the ongoing nuclear disaster at the Fukushima plant and its effects on Japan and the rest of the world. [...]

Arnold Gundersen, Nuclear Engineer: At Reactor 2… the conclusion is that fine pieces of nuclear fuel have escaped the containment and are lying as a powder on the bottom of the torus room.

Arnold Gundersen, Nuclear Engineer: So I think they get to the point where they throw some concrete down on the top of it and come back in 300 years… This is not something I can figure out how one would clean up… 300, 400, 500 years.

Gundersen: The particles escaped the torus… that’s what’s fascinating… these are outside containment… it’s quite clear that the junction between the torus and the dry part of the containment failed.

Arnold Gundersen, Nuclear Engineer: All the reactors have plutonium in them… Uranium-238 becomes plutonium-239 when it absorbs a neutron… There was close to a ton of plutonium in each of the reactors… scattered throughout the fuel… A ton of plutonium in each reactor… You and I know how dangerous plutonium can be… makes the cleanup that much more difficult.

Arnold Gundersen, Nuclear Engineer: I’ve been encouraging people on the West Coast to demand of their state government to take some samples because the US government is not taking samples. And of course what samples are being taken, if it’s below an arbitrary number, the authorities are not announcing what that number is.
I’m sure the authorities have caught fish and they’re contaminated and to avoid a public health scare, or more likely to avoid a business collapse in the fisheries, they’re not telling people what the number is.
Is the radiation high or low? I don’t know, but I’m sure they’re detecting it in fish even on the West Coast of the United States.
