...simple reactor of the Nautilus is not simple by normal standards. Its official name is STR (Submarine Thermal Reactor), because the neutrons that are its "fire" are slowed down to the "thermal" speed of molecules in everyday matter. Basically, it is a "core" containing enriched uranium,† cooled by ordinary water that is kept by high pressure from turning into steam. The water comes out of the reactor hot and radioactive. Tightly shielded against radiation, it goes through a "heat exchanger" (a kind of boiler), where it turns a second batch of water into high-pressure steam. The steam. which...

Zirconium. The STR, designed by Argonne National Laboratory and Westinghouse Electric Corp., was a staggering exercise in pioneer engineering. One enormous problem was the material for tubes and other structural parts in the reacting core. It must resist corrosion, and it must not absorb too many neutrons. The answer was the rare metal zirconium, then a laboratory curiosity. Its metallurgy was shockingly difficult, but Rickover pushed it so hard that he called himself "Mr. Zirconium...
