...Experimental Breeder Reactor No. 1 at the National Reactor Testing Station, Arco, Idaho, has been in operation since 1951, generating a small amount of electricity and yielding information of great importance to public utility companies that plan to build giant power reactors of similar type. Last year the laboratory began a series of risky but wholly legitimate experiments to find out how the reactors would behave during sudden power surges, i.e., sudden increases in the speed of the nuclear reaction. The first experiments went well. The temperature of the reacting core (about the size of a football and heavily shielded...
Both elements were later created deliberately by "fattening" plutonium with neutrons in the Arco, Idaho materials-testing reactor (TIME, March 8, 1954). but the news of their earlier and more violent birth was not declassified until this week. Probable reason: no one was supposed to know that UJ-238, which can be made to fission in a thermonuclear ex plosion, was a factor in Test Mike...
...revealed that one U.S. town has briefly been supplied all its electricity by a small atomic reactor. In a special test, Arco, Idaho (pop. 1,200) was cut off from its regular power supply for an hour last July 17, drew its current solely from a 2,000-kw. boiling-water-type "Borax" reactor at the AEC's testing station 20 miles away...
...development of atomic power, unlike the production of atomic weapons, has only recently begun to show signs of real progress. The few experimental nuclear power reactors now in operation (e.g., at Arco. Idaho and Oak Ridge, Tenn.) have yet to match conventional power plants in cost per kilowatt. Last week the Army and the Atomic Energy Commission announced plans for a significant practical advance in the field of atomic power: a compact, 1.700-kilowatt nuclear power plant that can be broken down and airlifted piece by piece to U.S. bases overseas...
Novel Reactor. The other reactors will be more unusual. One will be a "breeder" designed to make more fissionable fuel (plutonium) than the U-235 that it consumes. It will generate 15,000 kw. of electricity (the experimental breeder at Arco, Idaho generates only 170 kw.), and its pumps and other components will be big enough for a full-scale breeding power plant...
