Succesfull home brew and Japanese nulear failure

One of my hobby's is brewing my own beer. A couple of weeks ago I brewed a batch, yesterday I tasted the first bottle of it, and it is good. Without a doubt the best beer I've brewn so far. I've already tought of some changes I'll make to the recipe next time, but I'm very pleased with this result.

Then the thing everyone is talking about: the Japanese earthquake. The Earthquake in itself at this point seems pretty much irrelevant compared to the problems they are facing in there nuclear power plant. Personally, I don't believe that they've said everything. Both containment vessels are said to be intact, altough the buildings around them have exploded. The explosions of monday and saturday seemed quite large, but perhaps they are right, and the containment vessels are intact.

Then there is the story about the "partial" meltdown. At this point they acknowledge that probably in all three reactors there fuel rods are melting or have already melted (even on saturday there were rumors about melting fuel rods in two reactors. But the actual reactors would be intact. When the fuel rods are melting, that's a sign that it is very hot inside the reactor, and a mere 15 cm of steel isn't going to hold very long unless some very serious cooling is happening, which is aparently failing. Also, the increasing number of reports about radiation measured outside of the reactor complex to me seems like a very bad omen.

Last but not least, multiplt times already we've heard about radiation levels dropping after a few hours. This can only happen in to ways, Either the radioactive isotopes had short half-lives and had already decayed by the time of new measurments, or the isotopes had somehow flown away. But once radiation was measured, that simply meant that radioactive material had escaped and WILL decay outside of the reactor, regardless of whether or not radiation levels were lower a couple of hours later.

Let's just hope that they ae able to finally get a grip on this problem before it get's even worse.
