...power reactor now in prospect is the 60,000-kw. job announced last fall (TIME, Nov. 2). Commissioner Smyth described it this time in some detail. Its fuel will be "slightly enriched" uranium (more U-235 than in natural uranium), and its moderator and coolant will be ordinary water at 2,000-lbs.-per-sq.-in. pressure and a temperature between 500° and 600° F. This is not high pressure or temperature for a coal-burning steam plant, but it is unusual for a nuclear reactor, and Dr. Smyth anticipates a certain amount of trouble. He does...
...gaily. The diminutive Rickover had to strain to get a look, when the Nautilus splashed into the icy Thames and floated away in flotsam from the launching cradle. As four tugs fumed up and nudged her toward a fitting-out dock, the Nautilus rode high in the water (her reactor and other heavy parts have not yet been installed). As she disappeared out of sight of the stands, the sun suddenly disappeared with her and the fog closed in again on Groton...
...launching of the atomic submarine Nautilus, Vermont's Republican Senator Ralph E. Flanders, member of the Armed Services Committee, returned to Washington from Arco, Idaho, where the prototype of the submarine's reactor has been under test. Brimming with nuclear enthusiasm, he rushed to tell the President what he had seen...
Under the Senator's critical eyes, the landlocked submarine on the Idaho desert (see cut) made a simulated cruise. For four days it steamed at full speed while the energy in its propeller shaft, was absorbed by a pumplike water brake. Since the "fire" in its reactor used no air, it could have been steaming hundreds of feet under the surface of the sea. If the test had been run with the real Nautilus, she could have cruised submerged from Halifax to Liverpool (2,514 nautical miles) in 96 hours. Average speed (probably conservatively stated): 26 knots...
Both Rickover and Dr. Hafstad of the AEC have long believed that the U.S. should speed up this development process by financing civilian power reactors to use as proving grounds. Three months ago the AEC made a quick turn-around and decided to build a really big (60.000 kw.) reactor for a land power station. It gave the job to the practiced team of Rickover and Westinghouse...
