...deliberately by "fattening" plutonium with neutrons in the Arco, Idaho materials-testing reactor (TIME, March 8, 1954). but the news of their earlier and more violent birth was not declassified until this week. Probable reason: no one was supposed to know that UJ-238, which can be made to fission in a thermonuclear ex plosion, was a factor in Test Mike...
Some scientists thought Bhabha highly optimistic, but he insisted that he was actually speaking conservatively, that fusion power might come even sooner. Would fusion replace fission in reactors? he was asked. Said Bhabha: "There will probably be a place for all of them. Airplanes have not eliminated railroads...
Gentler Triggers. Although Bhabha was the first topflight scientist to predict the coming of H-power, the prospect has intrigued his brethren everywhere (TIME, July 25). Present atomic reactors all use the fission process: splitting nuclei of the heavier atoms, e.g., uranium or plutonium, to produce a controllable reaction. But fusion, used solely in the H-bomb, involves binding the nuclei of far more plentiful, lighter atoms (deuterium, lithium, etc.) under tremendous heat to produce an explosion...
...delegation made fusion seem even more tantalizing by releasing for the first time cost figures for fuel, for fusion and for fission. One pound of heavy hydrogen costs only $140; one pound of pure uranium 235, used as reactor fuel, costs a whopping $11,000. Most important, a fusion reactor's fuel supply is as inexhaustible as the oceans-in every gallon of water there is one part deuterium (heavy hydrogen) to 5,000 parts of light hydrogen, easily separated by electrolysis...
...useful to the scientists will be of no public interest at all. They will be minute details about obscure matters. One British paper, for instance, tells about the troublesome chemistry of ruthenium, a rare element that had almost no importance before atomic science was born. But it is a fission product formed in nuclear reactors, and it has to be dealt with during the purification of reactor fuels. The information in the U.S. paper probably represents hundreds of man-years of scientific labor...
