Pique the Geek 20110327: How Nuclear Reactors Work. Part the Second

There was a good bit of feedback from last week’s installment, and I want to point out that I am always glad when people point out flaws in my treatment.  I emphasized a particular sort of reactor, and neglected a couple of other ones.  I intend to set this right tonight.

The concern that seems to be in the forefront at present is the radiation leakage from the stricken plants.  As I write this (20110326), it is still not clear whence it comes, but I suspect that fuel rods are compromised and that nuclear fuel rod material is becoming commingled with the water that is supposed to cool the systems.

I say that because it is unlikely that if the spent fuel rod ponds were the source that the high levels of radioactive materials would have found their way into the turbine rooms, where the subcontractors were exposed to extremely high levels of radiation.

The primary thrust of this piece is to go through some of the fission products in the spent (and in use) fuel rods.  This will give us a basic understanding as to why used nuclear fuel is so much more dangerous than new fuel.

Social Security: Get On The Phone Tuesday And Wednesday And Help Fight Cuts

So it’s been about three weeks since we last had this conversation, but once again we have to take action to try to keep Social Security from being the victim of “deficit fever”.

I know that doesn’t make a lot of sense, considering the disconnect between Social Security and the deficit-but once again it’s “Continuing Resolution” time on Capitol Hill, where some use the threat of an impending shutdown of the Federal Government to extract concessions from the other side…and some on the other side try to make points with the voters by out-conceding their opponents.

So Tuesday and Wednesday of next week, there’s a national push on to get voters to call their Senators and remind them to vote for an Amendment that is a big ol’ “I’m not willing to cut Social Security just because other people philosophically want to cut Government any way they can” kind of reassurance to the voters, and I’m here to encourage you, once again, to make a couple phone calls and do some pushing of your own.

I’ve also been storing up a couple somewhat facetious random thoughts which will be the “garnish” for today’s dish; you’ll see them pop up as we go along.

After Libya, how could we NOT bomb Syria?

The self-propelling logic of war, a “news analysis” courtesy of the New York Times:

Syria … could pose a thorny dilemma for the administration…. Having intervened in Libya to prevent a wholesale slaughter in Benghazi, some analysts asked, how could the administration not do the same in Syria?

Hmmm?

Elsewhere in the NYT, Greg Mankiw demands “austerity now.”
