Spreading the Uranium. There may be much military importance in two side effects of the new fusion techniques. In fission bombs, a great deal of the uranium is scattered before it can react. But in a hydrogen bomb, even a small one, the ingredients packed around the uranium core could be induced to generate a large number of free neutrons. These would make more of the uranium react, thus stepping up the efficiency of the core's explosion...
Another limitation of the old-style uranium bombs is that the core must have a certain minimum size or it will not explode. Hydrogen bombs can be designed in such a way that a smaller core will detonate. So a stockpile of uranium (or plutonium) would go farther if built into hydrogen bombs than it would if used alone. This advantage would appeal to such nations as the U.S.S.R., if they have smaller hoards of uranium than...
