...more satisfactory system, says Physicist R. Philip Hammond of Los Alamos Scientific Laboratory, could be built around large nuclear reactors. In the magazine Nucleonics, Hammond explains that as reactors increase in size, the heat that they produce becomes cheaper and cheaper. Steam generated by a 10 million-kw. reactor costs only one-quarter as much as steam from a 1,000,000-kw. reactor. The necessary uranium fuel is relatively cheap, and most of the cost of running a nuclear reactor involves a variety of other items. But the cost of many of these increases only slightly as the plant...
...million-kw. reactor would produce heat cheaply enough for the sort of seawater distillery Physicist Hammond would like to use. But no such reactor has ever been built or seriously contemplated. The biggest one under construction in the U.S., at Bodega Bay north of San Francisco, will generate slightly more than 1,000,000 kw. of heat. For producing electric power, says Hammond, there is no present need for anything larger. But he is sure that the monsters he has in mind can be constructed without trouble. A 25 million-kw. distilling plant would suck in a river...
...Administration. Senator Anderson insists that nuclear-powered rocketry is as important to U.S. security as the hydrogen bomb. Moreover, the theory behind Rover is disarmingly simple. In present U.S. and Russian space rockets, thrust is produced by the combustion of highly volatile chemical propellants. In Rover, a small nuclear reactor will generate heat that will expand hydrogen. This, in turn, will be directed out of the rear of the rockets to provide thrust. Because the reactor and the hydrogen take up relatively little room, scientists estimate that Rover will be able to haul triple the loads of conventional rockets, could...
...this year it is running at some $200 million. Put to Kennedy at his news conference was the question of whether his trip had persuaded him to seek even more money to speed up Rover. His answer: "We are going to let these tests go on of the reactor. These tests should be completed by July. If they are successful, then we will put more money into the program." In other words, Rover must do more than sit up and beg if it hopes...
...capsule is far from a practical factory, but Aerojet is now building a pilot plant that will circulate a mixture of ammonia and uranium oxide through a nuclear reactor. If Aerojet calculations are correct, the plant should produce hydrazine, which now costs $1.50-$2 per lb., for as little...
