View Full Version : Can you make gold in a nuclear reactor? MCP 08-22-06, 10:44 AM And is it commercially viable? I'm guessing the 2nd answer is no... Nasor 08-22-06, 01:34 PM Yes...radioactive gold. James R 08-22-06, 09:09 PM It's not commercially viable. alain 08-23-06, 01:06 AM The small numbered elements on the periodic table (ie gold) aren't really prone to radiation, unlike the higher numbered elements such as plutonium G. F. Schleebenhorst 08-23-06, 11:26 AM Even if you could, gold would eventually become worthless. So not much point really. spuriousmonkey 08-23-06, 11:28 AM It is already quite worthless. Walter L. Wagner 08-23-06, 01:24 PM OK, it's worthless. Tell you what. I'll buy all of your Gold for 10 Euros/kilogram, a fair price for such a worthless commodity, OK? Any takers? sderenzi 08-28-06, 01:11 PM I seek to have gold in exchange for woman, LOL Kendall 08-29-06, 03:02 AM It takes alot more than a neuclear reactor, tempature, pressure, energy I could only guess what else, the best theory I have heard is every element comes from hydrogen and the stars turn elements into other elements, The planets are piles of stardust. I read of scientist's who turned lead into gold but cost a fortune, you would have to create the enviroment of the inside of a star and control it! pilpaX 08-29-06, 06:06 AM I read of scientist's who turned lead into gold but cost a fortune, you would have to create the enviroment of the inside of a star and control it! isnt that called nuclear fusion? Avatar 08-29-06, 06:23 AM Yes, and for that you'd need a nuclear fusion reactor. At this stage all are experimental. The first of the commercial type would be the international ITER project/reactor. All the current nuclear power plants use nuclear fission. cato 08-29-06, 06:32 AM also, I imagine that ITER would still cost more to produce gold than getting it out of the ground. Avatar 08-29-06, 07:01 AM Yes, I too imagine that. weed_eater_guy 08-29-06, 09:33 AM but if someone did produce gold commercially and was succesful, it would loose value, but would still be a very good non-corrosive metal for industrial and other applications. it's also almost as good a conductor as silver if i remember right, better than steal or copper. ever wonder why premium A/V cabling has a gold tint to the metal on the plugs? but yeah, the value would drop, meaning whoever produced it woudl have to constantly make their operation more efficient, by like several hundred percent. maybe it could be done, but it is fusion after all. and now that I think about it... fusion doesn't make gold like you think it does. once a star fuses iron, it suddenly takes more energy to make fusion happen than will come out of it. period. when iron forms in a star, it's a very small matter of time (minutes) before it supernovas. however, the massive supernova explosion smashes enough to gether to make elements heavier than iron, including lead, uranium, and GOLD. You wouldn't have to replicate the inside of a star, you'd have to replicate the inside of a supernova, the most devistating naturally occuring explosive force mankind is aware of! entreprenuers, get to it! mountainhare 08-29-06, 09:42 AM Reminds me of that Superman episode from the 1950's, where the crooks force that guy to make gold with his new invention. And it turns out that more money is used to make the gold, then you can sell it for on the market! BACKFIRE! Walter L. Wagner 08-29-06, 01:33 PM Of course, you can make radioactive gold quite easily by neutron irradiation of other elements. That's done all the time.

Walter L. Wagner 08-29-06, 10:51 PM Kendall: Why not go to a dictionary and look it up. Or an encyclopedia. Or Wikipedia. Maast 08-31-06, 06:35 PM Fission, atoms are broken apart by high energy neutrons, in uranium and up the periodic table (transuranic elements) the breaking apart of the atom releases energy and more neutrons, which go on to break apart more atoms. Fusion: atoms are fused together releasing energy and making elements higher up in the periodic table up to iron where it takes more energy to fuse iron atoms than it releases. Example, 2 hydrogen atoms fuse together to make a helium atom, 2 heliums together make beryllium (I think, might be lithium) etc TimeTraveler 08-31-06, 11:24 PM Alchemy? Vega 09-12-06, 01:20 PM The artificial production of gold is the age-old dream of the alchemists. It is possible in particle accelerators or nuclear reactors. Since there is only one stable gold isotope, Au-197, nuclear reactions must create this isotope in order to produce usable gold. In a nuclear reactor gold can be manufactured by irradiation of platinum or mercury. Since platinum is more expensive than gold, platinum is economically unsuitable as a raw material. Only the mercury isotope Hg-196, which occurs with a frequency of 0.15% in natural mercury, can be converted to gold by neutron capture, and following K+- decay into Au-197 with slow neutrons. Other mercury isotopes are converted when irradiated with slow neutrons into one another or formed mercury isotopes, which beta decay into thallium. Using fast neutrons, the mercury isotope Hg-198, which is contained to 9.97% in natural mercury, can be converted by splitting off a neutron and becoming Hg-197, which then disintegrates to stable gold. This reaction, however, possesses a smaller activation cross-section and is feasible only with un-moderated reactors. It is also possible to eject several neutrons with very high energy into the other mercury isotopes in order to get the Hg-197. However such high-energy neutrons can be produced only by particle accelerators. |
