...appointment system is very simple. In 1939 the Faculty determined the "historical" size of each department. The exact details of the process are shrouded in mystery. "Historical" size depended to a certain degree upon size at the time, and to a small degree upon number of students and concentrators. Endowments played a role: for instance, the Department of Semitic Languages and History had two chairs endowed for over $118,000. Although the department then offered only nine courses for a total of 38 undergraduates and graduates, to throw out one of the professors would have meant giving up completely...
...remainder of the period was slower. Defenseman Algie Allen and wing Bill Garrity repeated the process of the Carman-to-Huntington goal at 7:59, but at 15:21 a Tufts pass play beat Phil Clark in the Crimson goal. Clark was playing in place of John Chase, who was resting a broken finger from the BU game...
...than the U-235 consumed, the pile could continue in operation for a very long time. First the original U-235 would be consumed, yielding energy and plutonium made out of 11-238. Then some of the plutonium would fission, yielding energy and creating more atomic fuel. Theoretically, the process might continue until all the 11-238 is consumed. Natural uranium could yield something like 140 times as much energy as it would if only its U-235 were utilized...
...efficiency. The accumulation of radioactive fission products as impurities in the uranium, for instance, will certainly cause trouble long before the action is complete. But the contaminated uranium could be purified and "recycled." The AEC did not say so, but there is a possibility that when the breeding process has been refined, the uranium can be run through the reactor again & again until essentially all of it has been turned into energy. The world might thus have a practically inexhaustible source of nuclear fuel...
Although the AEC emphasized the peaceful aspects of its new process, the military aspects are important too. Fissionable material, however obtained, can be burned in a peaceful reactor or detonated in a bomb. If the new converter works as well as expected, it will help the U.S. make more bombs out of less uranium...
