Above 3-Ion section wifi form lop of 85-ft experimental stock North American Builds Atomic Power Plant Atomic rowan CEftcRATiow moved closer to reality with the announcement that North American Aviation ts ready to build e pilot plant. The company, working under contract with the Alomio Energy Commission, will use the new plant for producing electrical power for civilian use. North American has already built a scale model complete with flashing lights, moving control rods and Celger counters. Estimated cost for the plant it self Is 110 million. Although certain phases of design ore restricted, plans are available for inspection through the A EC by all persons and concerns cleared for access to classified data. The pilot plant will generate power from the tremendous amount ol heat produced during fission. Liquid metal will circulate through the reactor, obsoru heat and then pass Into an ordinary boiler to produce steam. The plant's output will be about 8000 kw--enough power to supply 2000 average homes. This power could be used for other otomlc research at the site of the re actor. Externally, the pilot plant will re semble an ordinary electrical power plant except for lack of coal, oil or other similar fuel-handling equipment. Unlike conventional installations, this new plant will produce neither smoko nor fumes. Although plant research and investigation will require additional scientists and engineers, routine opera tion of the new unit will require no more personnel than conventional plants. Spe cial control devices and built-in char acteristics of the design wilt provide the necessary safety factor. At present, costs for producing elec tricity by atomic fission are higher than eosts of conventional methods. However, the new development will provide valu able research that can help put such plants on - a competitive basis. Also, atomic power generating plants enjoy a distinct advantage over conventions! In stallations in areas where fuels such as coal, oil and gas are scarce.
