kitsune_, wrong choice of words, IMHO! The article is full of facts that make absolute sense and shed light on a large number of things that the news do not get right. My thanks to the author especially for a clear interpretation of the explosions. We need a clear head and should rely on facts in these situations. We also should not assume that nuclear reactors are not well constructed. I am sure they are. So it does not come as a surprise to me, that someone who knows the details is able to explain them in a way that it makes sense. This does not excuse the fact that the reactors failed. This is a different story. But it helps to understand what really happens now. What the author did not stress is the fact that, as the Zircaloy structure may have failed, all subsequent pressure releases will be highly contaminated. BTW, engineers are the ones who know best how safety is constructed, not scientists (I write this as someone who got his phd in atomic physics. So I am not an engineer).
