...alliance with the U.S. At the Berlin Conference, with a divided government and country behind him, he spoke out firmly and unequivocally. "He is a realist who will not let the dream of the best prevent him from grasping the good," said one who considers himself a friend. "The core of Bidault is rigidly moral and deeply religious." On such a man last week fell the bitter task of laying before the Communists France's terms of retreat in Indo-China...
FUSION BOOST Another trick available to researchers is to place in the fissionable core a small amount of highly reactive tritium, perhaps mixed with deuterium. Both the isotopes are light gases, and so they can be highly compressed and confined inside the metal. They can also be dispersed through it in some chemical or mechanical way. When the detonator explodes in such a rig, the tritium reacts, turning into helium and raising the temperature of the explosion. Such "fusion-boosted" detonators are much discussed among hydrogen-bomb connoisseurs. The long series of "nuclear devices" that the Atomic Energy Commission tested...
...even be possible to get along with no tritium in the detonator. A highly efficient fusion bomb may raise the temperature high enough to ignite the lithium hydride. Or perhaps it may, by "implosion." cause the fusion of a core made of deuterium alone...
...fair guess is that it may be heavy water. Since the reactor will be a breeder, it must be economical of neutrons, and heavy water does not absorb as many neutrons as ordinary water does. Instead of breeding U-238 into plutonium, the excess neutrons from its reacting core will be absorbed in thorium, turning it into fissionable U-233-Thorium is probably more plentiful than uranium, and it has been discussed for years as a promising source of nuclear energy. This is the first time that the AEC has shown by a definite commitment that it takes thorium seriously...
...real problem seems to like at the economic core of the "New Look." Because nothing but a war can test a fighting force, military men themselves are divided on its prospects. With a note of warning, General Matthew Ridgway commented on the "New Look" before a Senate committee last week. "We are steadily reducing Army forces," he said, "a reduction through which our capabilities will be lowered while our responsibilities for meeting the continued enemy threat have yet to be correspondingly lessened." Contested on technical as well as on policy grounds, the Administration's "New Look" in defense faces unsure...
