...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...
...liquid lithium flows through the hot reactor core and emerges at 2,000° F. The tubes that carry it, made of zirconium-columbium alloy, run at near white heat. The lithium is piped through a heat exchanger and turns liquid potassium (boiling point, 1,400° F.) to high-pressure gas that runs a turbine producing 300 kw. to 1,000 kw. of electricity. The potassium gas goes to a wide, flat condenser to be turned back into a liquid (see diagram...
...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...
Aerojet scientists mixed liquid ammonia (NH3) with powdered uranium oxide, sealed the mixture in a capsule and stuck the capsule in a nuclear reactor at Livermore Laboratory. When neutrons from the reactor hit uranium atoms in the capsule, they caused the atoms to fission, or split. The atomic fragments shot apart with enormous energy (200 million electron volts per fission), splintering ammonia molecules and knocking them in every direction. The fragments recombined at once. Some formed gaseous hydrogen (H2) or nitrogen (N2). But about half the ammonia that reacted formed the much-desired hydrazine (N2H4...
