This was the concern of researchers considering storing radioactive waste at at site in Yucca Mountain, Nevada. Although they said the scenario is improbable due to all the factors needed to come together at once, they could not state that it absolutely couldn't happen if the right things came together.

They're WASTES. Most of the energy has been taken out of them already. They are radioactive, and therefore dangerous, but no more likely to explode than the cooling ashes of a wood fire are apt to spontaneously burst into flame. "

When reading material like the above mentioned article in SCIENCE, one must keep in mind that they are in the business of selling magazines, and sensational articles sell magazines. It is in their best interest to write about things that excite people like the threat of a nuclear mishap. The 'scientists' mentioned above failed to state just how improbable reaching critical mass would be... it's on the order of lead turning to gold all by itself. Of course, it *could* happen. There is always a finite, non-zero possibility that the improbable or even impossible could happen. For instance, the sun could suddenly transpose itself with Jupiter due to a freak quantum mechanical incident. Bad things would happen. But I don't lose any sleep over that possibility. It really bugs me how journalists distort facts the way they do. Usually for some political agenda, no less. Sorry for ranting on, folks.

In fact, you will probably never see it on a news stand. It's a multidisciplinary journal, not a magazine, and one of the most highly respected publications in scientific circles. They employ a "just the facts" kind of reporting. And the "scientists" were from the Los Alamos National Laboratory and the engineering department of Berkley. Fairly reliable, in my book. I did misquote - although not on purpose - regarding the waste that was proposed to be buried. Part of the study did consider the burying of enriched uranium and plutonium from dismantled nuclear weapons, thus not all of it would be spent fuel. Sorry for any misrepresentation. -PTS.

Science is one of the most well-respected TECHNICAL journals around, it is NOT a "popular" magazine. The research published in Science is peer-reviewed, which means that several experts must approve the article prior to its publication. The research which appears in Science is written by scientists, not journalists. (Sometimes you can tell, because journalists on the average write better.)

Sure it can! By the same reasoning I can state that nothing that comes out of a nuclear power plant is "waste". Any radio-isotope (aka all the daughter particles from the fission process) can be used as an energy source, and can be put in radio-isotope batteries. Thus there is no such thing as "nuclear waste". > Uh, doesn't plutonium come from the Planet Pluto? No! Everbody knows that dogs come from Pluto!

We have been discussing weather nuke waste can explode. Well, I think we have decided that it can't. It is just waste, and not realy useful for anything, except creating the premis for a great TV show :-). Getting back to the Evil Koenig idea, what if he was?? Sorta. Lets look at it for a moment... Commander Gorski is relieved of command. To me, it was not the regular transfer of power after a tour of duty. It seems to me that Gorski was fired, and Koenig placed in command. Why?? The whole Ultraprobe fiasco. Gorski was willing to spill the beans on the problem, but Commissioner Simmonds didn't want that info to get out. So, fire Gorski, and put your own man in there. While Koenig may not have known all that was going on, he was niave enough not to suspect that there was some type of cover up about the waste areas. What if they were storing weapons grade nuke stuff there?? That could explode. Especialy if it was being treated as waste, and stored accordingly, and not like active nuke that it was. If it is not stored properly, things can go wrong. And thats what happened. Kaaboooom!!!!! We don't know much about Earth history in the 1999 universe, but we can speculate. Say it was something like we have now. The wall has come down, Russia has gone the way of the dinosaurs, and the weapons are being dismantled. What if this is the same in 1999?? So, we have all this weapons grade material that is suposed to be destroyed or stored away. Then you get someone like Buchanan in the Presedential position. He still doesn't trust the 'Ruskies' and wants to maintain their power of the rest. So, he says '..we have XX amount stored now...', but all along, he has been skimming off the top and sending it to the moon as waste to be hidden from the other superpowers. But, not being able to trust all the people that would be involved in the cover up, they simple don't tell the people involved. And they go on their way of improperly storing this material. Why do you think they upgraded the way they stored 'waste' in "Area 2"?? They called it safety reasons. What if it was that, not because the waste was the problem, but the active material. If it worked before, why change the proceedure??? Just some thoughts....

Why can't our brilliant bureaucrats come up with simple solutions? Simmons and Dixon are alive, well, and at work right now, in 1996, ready to mess up our lives. Are these "Physicists" demanding a containment system that will protect us from doled waste long after natural uranium already in the ground has already killed us?

I certainly hope you're not serious... but here's one possible reason. It's not Uranium Ore anymore. It's a concentrate of many different isotopes that's far more radioactive. I have heard stories that a very unpleasant thing happens if you just throw the stuff into a hole in the ground: diffusion purification. Some of the isotopes are more motile through the soil than others. Over time you build up layers of isotopes that can theoretically get concentrated enough to chain fission. This has apparently happened at least once in the country once known as the Soviet Union. Amardeep

Yes, the communists in the USSR were in a hurry to build their bomb in time for Stalin's 70th birthday, and just dumped wastes in mines near Chelyabinsk. Later they did explode, around 1956, but the reaction was a chemical one, not chain fission. Government bureaucrats caused that problem by being careless, just as they are now causing a problem by being overly zealous. I have read in Scientific American that natural uranium deposits somewhere in Africa (Ghana? Gabon?) did achieve criticality millions of years ago. That is, they became a natural reactor, but not a bomb. And the waste products aren't seeping up, creating mutant africans, or killing them. The ground would be the last line of defense in containing waste, and the people in Africa who live above and around that natural reactor waste aren't mutants or dying. Glass is a cheap and incredibly inert, and sealing the wastes in tiny glass beads is very reasonable. This would be the first line of defense against release. Other layers would be lead tanks and concrete walls, then a mile or so of rock. The world's natural sources of radioactive solids aren't contained by engineered glass, lead, or concrete, and aren't poisoning people. The biggest sources of harmful radiation are radon seeping into your basement, and exposure to sunlight. That money- hungry bureaucrats are more concerned about buried nuclear waste poisoning people than radon or beaches is so typical of these stupid Simmons. If they were really concerned, they would close all the beaches and outlaw tanning beds. Instead they focus on a gnat (nuclear waste) while letting everybody swallow camel loads of radon and ultraviolet. Ronald

Is it currently cost prohibitive to shoot our current stockpile of radioactive waste to the sun in a disposable booster instead of reburying it in "protective" dumps?

Date: Sun, 21 Apr 1996 07:13:35 -0700 From: Ronald Dudley (dudleyrd@expert.cc.purdue4tag.edu) "Uranium Enrichment" is a refining process, in which atoms are separated, by their nuclear weight. It is not the altering of the nuclei of the atoms. Sending waste into the Sun can work, but to be pedantic, the surface of the sun is not hot enough break heavy elements down into light ones. Economics precludes this because of the energy needed to shoot dozens of rockets into the Sun, or even the cheap way by shooting them to Jupiter, and letting Jupiter's gravity whip the waste around onto a collision course with the Sun. The "danger" of storing it on Earth is relative. Radon gas is a dangerous source of radiation, and seeps into people's basement, and accumulates due to poor ventillation, but the government doesn't have to impoverish us to save us from Radon gas. It is absolutely crazy that the government is going to dump a trillion into protecting us from nuclear waste, while letting everybody go to the beach and get zapped by cancer-causing ultraviolet radiation. The Sun is the biggest nuclear explosion for light years around, yet people take off their clothes so as to get a good unhealthy dose of its rays, while worring about waste a mile underground. Simply Crazy! Why not worry about all the natural uranium ore that is already down there? Its an anti-technology prejudice to have nuclear waste as such a high priority, yet be unconcerned about natural sources of even more harmful radiation. Luddites! Unabombers! To achieve "critical mass", you not only have to have a certain ammount of mass, but also the atoms must achieve a certain density, so that neutrons given off have sufficient probability of hitting other atoms. Nuclear fuel is engineered so as achieve criticality. Nuclear waste has lots of junk atoms in it, which interferes with the chain reaction in such a way that no ammount of it won't achieve the chain reaction because the target atoms are too separated and shielded from eachother by junk atoms. Fission explosions are engineered events, and do not happen in nature. Chemical explosions, like swamp gas igniting, can happen naturally. Accidental chemical explosions happen often, particularly because our atmosphere is 20% oxygen, but accidential fission explosions are as imaginary as a book being written accidentally by 100 monkeys typing on 100 typewriters, or by an explosion in a printing factory. Perhaps on an imaginary world with lakes of liquid uranium might you observe a spontaneous fission explosion. Fission explosions are engineered processes, and even then require a chemical explosion to ignite them, so as to compress the uranium/plutonium into a small enough space so that it goes critical. Expecting waste to explode by fission is like expecting the silicon in beach sand to accidentally turn into a microchip on a sunny day. Ronald #122 SDSE
