TEMPERATURE DEPENDENCE OF TAFEL SLOPE IN THE FORMATION OF VERY THIN ANODIC OXIDE FILMS ON NIOBIUM
A kinetic study was made of the formation of very thin anodic oxide films on niobium at constant current over the temperature range --10 to 70 deg C. Formation voltages were limited to the range below the oxygen evolution potential to eliminate possible interaction of an electronic component of the current with the measured formation field. It was found that the measured temperature dependence of Tafel slope agreed with that predicted by the theory of Mott and Cabrera. Using this theory, a zero field interfacial barrier height of 1.19 ev and a half-jump distance of 2.40 A were obtained. Values of the differential formation field are reported at current densities of 1000, 100, 10, and 1 mu a/ cm/sup 2/ at ten degree intervals over the temperature range studied. (auth)

The Transfer of Plutonium Hexafluoride in the Vapor Phase
Plutonium hexafluoride is decomposed by heat, by its alpha radiation, and by reactions with most materials of construction. Laboratory experiments were performed to investigate means by which plutonium losses due to these reactions can be minimized during vapor-phase transfers of the compound. The experiments showed that plutonium hexafluoride vapor could be transferred satisfactorily through well fluorinated nickel equipment in a stream of fluorine or helium. The decomposition product of plutonium hexafluoride was refluorinated at 250 deg C by fluorine. (auth)

Pressure Induced Metallic Transitions in Insulators
Experimental evidence that several ionic and molecular crystals become conductors in the metallic range at ~ 250,000 atm. is presented. For some the transition pressure is roughly defined. (T. R.H.)

An Investigation of the Application of the Gas Generator-Free Turbine Cycle to a Nuclear Powered Aircraft
This study has investigated the feasibility of installing a gas generator-free turbine type power plant in the R3Y aircraft, using a circulating fuel reactor as a power source. Two variations of the cycle were considered. The split flow cycle bleeds high temperature, high pressure air from the gas generator directly to the free turbine in the wing. The through flow cycle partially expands the high temperature, high pressure air through the compressor turbine of the gas generator then directs the compressor-turbine exhaust air to the free turbine in the wing. Design parameters of pressure ratio, radiator depth, radiation flow density, and hot gas duct size were optimized to give minimum weight per shaft horsepower of the complete power plant. The weight of a split flow power plant capable of supplying 22,000 shaft horsepower was found to be 116,600 pounds. The weight of a similar through flow power plant was found to be 119,900 pounds. The reactor power required in both cases was 70 megawatts. The nominal gross weight of the R3Y airplane is 175,000 pounds. With pay loads of approximately 20,000 pounds, either nuclear conversion will have a gross weight of 200,000 pounds. It was found that either cycle could …
