TARlt.T OOCTTBK THURSDAY, APRIL f, 1»M Construction of Atomic Sub Engines Underway (Editor's Note: This Is one of §«v»r»l stories by Elton C. Fay, AstoeUted Press military affairs reporter, on one of the first visits bjr « newsman to ttie cross-country ehuln of laboratories and plants buHdlng ttie atomic-powered submarine.) By ELTON C. FAT PITTSBURGH. April 2 UP) — So •wift Is the pace that manufacture of the operating engine for the first atomic-powered submarine already Is under way. Obviously assured by what It Is learning from the prototype engine under test at Idaho Palls, Idaho, the Atomic Energy Commission (AEC) has directed Westinghouse Electric Corp. to start work on the seagoing version which will bo Installed in the submarine Nautilus. This start on the assembly of the nuclear reactor and steam propulsion machinery does not necessarily mean the design of atomic submarine power plants has been "frozen." It does mean AEC scientists and Navy designers "believe they have an atomic power plant which will propel a submarine probably faster and certainly longer without refueling than any engine existing today. No one expects this nuclear power plant to operate flawlessly the first time the Nautilus puts to sea. It li still highly experimental. It will hava "bugs," as any newly designed machinery does. But until the engineering force first gets up steam in a dockslde test «nd the Nautilus makes her maiden voyage, the designers won't know nil the fine changes in design detail that must be marie. The power plant for the Nautilus is built around a "thermal" reactor, with a water coolant lor transfer of the atomically produced heat to steam turbines. Nuclear physicists call the devices "reactors"—which in layman's language means furnaces. The first reactors were, and still are, used for producing refined fissionable material, including plutonium, which goes into the manufacture of atomic bombs. The heat in those reactors is an unnecessary and undesirable by-product disposed of by elaborate water- cooling systesm. But now they want the heat to produce power to drive naval vessels and later industrial machinery. So the intense local heating of n reactor is being tapped. Two types of reactors arc to be used in two submarines to see ] which works best—the thermal reactor in which the speed or energy of neutrons released in the fission process is relatively low; an Intermediate reactor In which neutron release is faster. The relatively low neutron speed of the thermal reactor means that ordinary steel and other materials Super Market Workers Quit- To Give Blood WILLIAMSON, W. Va.

To meet this situation, scientists of the AEC, the Bureau of Mines, of the WestinBhonse Corp. and of a number of other firms turned to n metal little known or used until they demanded it in fjuantity—zir- conium. Zirconium looks, feels, weighs and generally appears to be much ike higlHjrado steel. But it has the happy advantage of neutron absorption far lower than steel. It is used for key parts of the reactor'B core. When the AEC and Westinghouse started looking (or quantities of zirconium it cost over $200 a pound tnd was obtainable usually In lots of only about five pounds. Produc- ,ion now Is coming in at the rate )f 200.000 pounds a year and the cost is down to about $15 a pound. Lawton D. Goiter, manager of the Pittsburgh AEC area, sums up the program for building the atomic power plant to drive the first such submarine (his way: "Nothing has come up that would mnke us feel the least bit pessimistic. We are, going right tthcad." Nation-Wide Strike Is Called By U. S. Rubber Employes NEW YORK W> — A CIO union struck early today against the U. S. Rubber Company across the nation after contract negotiations here became deadlocked. Thirty-five thousand employes In 10 .plants were affected. Negotiations were scheduled to resume today, and a company spokesman said he was "very definitely optimistic" about early settlement. He estimated the strike would last no longer than two or three days, if that long, A spokesman for the CIO United Rubber Workers declined to make any prediction. A company spokesman said "all but three or four" of the 19 plants —many of which work around the clock — had been struck before dawn. Day-shift workers were expected to complete the shutdown. Pickets started appearing as the strike deadline passed. No wage demand is involved in the dispute, the company spokesman said. Among the issues he listed hospitalization, pension plan revision and the length of the new contract. The company wants a longer contract than the union does. The 19 company plants and the estimated number of employes in the larger ones were listed by a company representative as: Nau- gntuck, Conn, (three plants). 6.000; Mishawakn, Ind., 4.500; Detroit. 4.000; Providence. R. I., 3,200; Chicopee Palls, Mass., 3,000; Los Angeles, 3,000; Passaic, N. J., 3,100; Indianapolis, 2,500; Ft. Wayne, Ind.. 1,800; Bristol, R.

Panama Wants New Terms fo r Canal Rental PANAMA, Panama W)—President Joso Antonio Remon reportedly wli: send Foreign Minister Jose Ramon Guizado to Washington soon to seek new terms for U. S. rental of the Panama Canal Zone. The newspaper La Hora said yesterday that the President disclosed plans for the trip in an Interview but did not announce a date. Oulzado now Is In Mexico. Remon previously said the $250,000 in gold this country receives annually from the U. S, In payment •or use of the canal Is not enough. Three-D Movies May Stop Petting WHEELING. W. Va.
