(you know, i never actually knew how enriched uranium was made. now that iran is declaring itself a member of the nuclear gang our press is finally informing me)
"The enrichment process is one of the most difficult steps in developing a nuclear program. It requires a complicated plumbing network of pipes connecting centrifuges that can operate flawless for months or years.
The process aims to produce a gas high with an increased percentage of uranium-235, the isotope needed for nuclear fission, which is much rarer than the more prevalent isotope uranium 238.
A gas made from raw uranium is pumped into a centrifuge, which spins, causing a small portion of the heavier uranium-238 to drop away. The gas then proceeds to the next centrifuge, where the process is repeated. Then it goes to another, and another, and another, in a chain that can involve thousands of centrifuges and gradually increases the proportion of uranium-235.
The enrichment process can take years to produce a gas rich enough in uranium-235 that it can be used to power a nuclear reactor or produce a bomb. Enrichment typically starts out with a gas that is 0.7 percent uranium-235, and boosts it to either 4 percent for power generation or to 90 percent for weaponry. "
YESYESYES!!! cheney roundly and loudly booed as he throws out the first pitch before the washington nationals game. that's gotta be a first (roseanne and maisy whosit were booed after they mangled the national anthem, which does no one's musicality any favors anyway). fortunately, as thinkprogress notes, the ball hit the dirt, not someone's face.
i wasn't gonna post about this, but it's hitting the newspapers now. and it may not be going away. an attempt to jam phonelines at a democratic get out the vote hotline center that was offering rides to people in order to get them to theie polling places. we already have one conviction, two plea bargains and a massive phone bill to ken mehlman's office the day before and day of.
man, this is a lot of people:
and greg palast (a noble dirty little commie) sent me a letter today. to wit:
"America is a nation of losers. It's the best thing about us. We're the dregs,what the rest of the world barfed up and threw on our shores. John Kennedy said we are "a nation of immigrants." That's the sanitized phrase.We are, in fact, a nation of refugees who, despite the bastards in white sheets and the know-nothings in Congress, have held open the Golden Door to a dark planet. Looking out at the tempest-tossed sea of protesting immigrants today, I finally figured out what's wrong with George Walker Bush. He's so far away from his refugee loser roots that he just doesn't get what it is to be American. So he steals the one thing that every American is handed off the boat: a chance. It's not just the immigrants denied a green card. When Bush threatens to take away your Social Security; when Bush's oil wars hike the price of crude and threaten your union-scale job at the airline; when Bush tells you sleeper cells aresleeping under your staircase, you don't take chances anymore -- you lose your chance -- and the land of opportunity becomes a landscape of fear, an armed madhouse. You want to say that George W. Bush is an evil sonovabitch? I'd go further: he's UN-AMERICAN. And that's why he lost the election. Twice. I'll stick with the losers. Take one, Anna, from Poland, who snuck across the US border near Windsor, Ontario. She was grabbed by La Migra -- 80 years later --just short of her 100th birthday. My father told Immigration, "OK, send her back." They didn't. Grandma Anna taught me what two million marchers this week are trying to teach that slow learner, George W.: In America, it's not where you come from that counts, it's where you're going. "
