...factory, built in 1982, is part of the fuel supply line for an experimental fast-breeder nuclear power plant. It is where fissionable U-235 is combined with nitric acid to produce uranium dioxide, which is then combined at another plant with plutonium to produce the enriched uranium pellets used as breeder fuel. According to JCO, workers inexplicably mixed far more than the normal amount of uranium--35.2 lbs. instead of 5.2 lbs.--with the acid. Then they used stainless-steel buckets rather than pipes--again, inexplicably--to pour the liquefied uranium into the tank. The high concentration of uranium...
...Pope and his team almost found nuclear fission in 1934 in the course of experiments in which, looking for radioactive transformations, they systematically bombarded one element after another with the newly discovered neutron. They missed by the thickness of the sheet of foil in which they wrapped their uranium sample; the foil blocked the fission fragments that their instruments would otherwise have recorded. It was a blessing in disguise. If fission had come to light in the mid-1930s, while the democracies still slept, Nazi Germany would have won a long lead toward building an atom bomb. In compensation, Fermi...
...Hitler had not hounded Jewish scientists out of Europe, the Anglo-American atom bomb program sparked by the discovery of fission late in 1938 would have found itself shorthanded. Most Allied physicists had already been put to work developing radar and the proximity fuse, inventions of more immediate value. Fermi and his fellow emigres--Hungarians Leo Szilard, Eugene Wigner, John von Neumann and Edward Teller, German Hans Bethe--formed the heart of the bomb squad. In 1939, still officially enemy aliens, Fermi and Szilard co-invented the nuclear reactor at Columbia University, sketching out a three-dimensional lattice of uranium...
Around noon on Monday, Indian soldiers descend on villages just a few miles from the desert test range and order the pacifist Bishnoi herdsmen, who refuse to kill animals or cut down trees, to evacuate. At precisely 3:45 p.m., three devices explode in five seconds: a normal fission bomb, a low-yield bomb for tactical battlefield use and something like a hydrogen bomb, which U.S. officials later insist could have been only a less powerful "boosted" weapon using tritium fuses to amplify the fission chain reaction. Altogether they unleash around 80 kilotons of atomic power, six times as powerful...
...century has also learned to recognize evil in the violent eruptions of nonentities: an absolutely insignificant man bursts out of the rented room into sudden, violent, gaudy, world prominence. Tiny cause, titanic effect--this is the social equivalent of splitting the atom. When Nonentity massacres Innocence, an especially horrible fission occurs...
