...Cold. Six years ago, as the atomic age mushroomed, Britain suddenly found herself out in the cold without a bomb or blueprint. By act of Congress, foreign scientists were barred from U.S. atom laboratories, unceremoniously ending the wartime cooperation that led to the A-bomb discovery...
...atom bombs of World War II were bulky monsters weighing close to five tons. The B295 that atom-bombed Japan carried only one on each mission. But atom bombs have been getting smaller and handier. The Army's description last week of its atomic gun gives an idea of how small a modern atom bomb...
...bore is 280 millimeters (11 in.). Since the vital parts of an atom bomb must be roughly spherical, the atomic explosive packed into the gun's shell is not likely to be much larger than a sphere eleven inches in diameter (a regulation basketball...
...were found in the Belgian Congo, the mines closed. Later, the area became a major producer of vanadium, also from carnotite, a metal used to harden steel. But not until World War II did its biggest boom develop. Tailings from radium and vanadium plants provided uranium for the first atom bombs...
...Arco breeder is about the size of a football. It is made of "enriched uranium," i.e., uranium rich in fissionable 11-235. Around the core is a "fertile blanket" of 11-238, the spent metal that remains when U-235 is extracted from natural uranium to make atom bombs. Through both blanket and core circulates a sodium-potassium alloy that is liquid at ordinary temperatures. This coolant carries away the heat of the nuclear reaction. The fluid metal leaves the reactor at 660° F., and produces enough steam to generate 250 kw. of power...
