...hard-thinking realists have not forgotten the lessons of history. Senator Dodd of Connecticut observed after the Soviet resumption of testing that the action proved the utter fatuity of the American moratorium. Moreover, it confirmed that Russia had been conducting tests underground all along. Although Mr. Rockefeller has not attained an equal mastery of the logic of Realpolitik, he is surely nobody's fool...
Conceivable objectives of surface testing include development of cheaper, more powerful, and more efficient warheads, try-outs for anti-missile missiles, and refinement of the "clean bomb." Tactical atomic weapons can be tested underground. A cursory examination of the technical factors suggests that the United States can afford to avoid surface testing...
Fallout from the latest and largest Soviet nuclear test was still drifting toward the U.S. last week when President Kennedy gave the go-ahead signal for Project Gnome, the Atomic Energy Commission's long-planned underground experiment in the peaceful applications of nuclear energy. Southeast of Carlsbad, N.Mex., a shaft has already been sunk 1,200 ft. in the ground to penetrate a thick formation of rock salt. From the shaft's bottom, a 1,116-ft. horizontal tunnel leads into the salt and curves back on itself in a giant hook. At the tip of the hook...
...nuclear bombs, even up to 100-megaton size, cost little more than small ones. By successive experiments the AEC lopes to learn how to store the energy of large explosions in salt or rock. If a multimegaton explosion can be safely confined underground, the power it produces may be cheap enough to compete with electricity from conventional sources...
...experiment with large-scale production of artificial isotopes. Isotopes that do lot exist in nature are generally made by bombarding natural elements with neurons in a reactor. A nuclear explosion underground will supply a vast number of neutrons for this purpose...
