...income, scheduled to drop to 47% after June 30, be maintained at present levels for another year. He also requested that the 10% excise on local telephone calls and transportation be continued, that the federal gasoline tax be raised from 4? to 4½?, that taxes on standard aviation fuel (now 2?) and jet fuels (now exempt) be put at 4½?, and that the rate on first-class letters go up from...
...that money, the Air Force will be able to buy 72 more Atlas and 50 more Titan missiles, bringing its intercontinental ballistic missile force to a total of 270 by the end of 1963. Also scheduled for the Air Force: $350 million for 15 test models of the solid-fuel, second-generation Minuteman missile (see SCIENCE...
...brought from town is better and fresher. Every night after work the "dacha husband" (as Chekhov called him) goes shopping, list in hand, and patiently queueing. Then, laden like a pack mule, he must wedge his way into a crowded train. His worst problem: kerosene, still the main cooking fuel in outlying places. The railroad bars it as dangerous, and if the dacha husband is caught carrying it, he will be put off the train and fined. He must therefore have a container sufficiently camouflaged to look like a food parcel...
...fuel is uranyl sulphate dissolved in heavy water (which does not absorb as many neutrons as ordinary water). When this solution is flowing in a small-bore pipe, it does not react, because the fissionable uranium atoms are too strung out to form a critical mass. But when the fuel solution flows into a spherical reaction chamber, the compact mass becomes critical. A nuclear chain reaction starts, and heats the solution. Before the reaction goes too far, the solution is sucked away by pumps and forced through a heat exchanger, where it heats ordinary water to produce high-pressure steam...
Worst problem was how to deal with the hot, corrosive, high-pressure fuel, which is fiercely radioactive as it comes from the spherical cell and cannot be handled or even observed except by special, remotely controlled devices. By ingenuity and careful engineering, Dr. Weinberg's staff managed to tame this lethal brew. His report proudly announced that "the reactor cell has been sealed with the circulating pumps running uninterruptedly for 1,600 hours (67 days), a feat which begins to approach the longest uninterrupted runs of any power reactor...
