>>Now we know that >>the Soviets have discovered plutonium behaves very unpredicatibly in >>relatively short term storage situations let alon 1000 years or eons. >We also know from the studies of the Oklo phenomenon that Pu migrates >very predictably (slowly) even when completely uncontained. The report in Science Magazine (Vol 287 # 5451,14 January 2000), by chemists Haschke, Allen, & Morales overturns long-held assumptions about what may happen when plutonium is buried. A commentary in the same issue of the magazine, entitled "Towards the End of PuO2's Suprem-acy?" discusses implications for long-term storage of plutonium dioxide: "It has ... been assumed for more than 50 years that PuO2 is the highest plutonium oxide which can be prepared. This oxide ... was believed to be stable over a wide temperature range.... For both civilian and military applications, the stability of PuO2 was a key factor underlying the industrial strategy ... The new results ... have great consequences for the underground disposal of plutonium wastes. Until now, it was assumed that plu-tonium would not be very mobile in the underground geological environment because of the insolubility of Pu(IV) compounds. But Haschke et al. demonstrate that water can oxide PuO2 into PuO2+x in which more than 25% of the plutonium ions exist as Pu(VI), an ion that is far more water soluble ..." >>Everytime you fellows say "Its a no-brainer" I'm convinced you don't >>use your brains. Next time that phrase comes to mind, maybe should >>realize that you sticking your head up your bosses ass. Yes Sir! >Oh. A comedian. :-| >...Greig
