Most current nuclear weapons, however, use a fission bomb to trigger soviet union the "fusion" of hydrogen nuclei. The resulting "thermonuclear" or "hydrogen bombs" are far more efficient and destructive than atomic bombs. There is in principle no limit to the power of hydrogen bombs. ^Back to soviet union top AT THE CORE OF THE BOMBS: URANIUM 235 AND PLUTONIUM 239 Natural uranium is mostly uranium 238, mixed with a small amount of soviet union uranium 235, the isotope used in bombs. Because the two forms are chemically identical (differing by three neutrons), the problem of purifying enough pure uranium 23 5 to make a bomb was very difficult and required an enormous industrial plant. |

| ^Back to top NUCLEAR FISSION AND CHAIN REACTION The atomic nucleus contains elementary particles called protons and neutrons. The nuclear energy holding them media studies together is thousands of times stronger than the chemical energy binding atoms together in molecules (like TNT, for example). For certain very heavy elements (uranium 235 and plutonium media studies 239), the nucleus is almost unstable, When hit by a neutron, it will split, or "fission," into two smaller nuclei, which fly violently apart, releasing nuclear energy and more neutrons. If a "critical mass" of such an element (a few kilograms) is rapidly brought together in a bomb, the average neutron cannot escape from the mass before it hits and splits another nucleus. This releases more neutrons, each of which repeats the process. The resulting runaway nuclear "chain reaction" bums through the fuel in a few millions of a second, liberating energy equal to that in many tons of conventional explosives. |
