A CONTINUOUS DAREX PROCESS FLOWSHEET

Description: A Darex flowsheet is presented wherein dissolution of stainiess steel- type fuel elements in dilute aqua regia, stripping of chloride from spent dissolver solution, adjustment of stripper product composition and rectification of HNO/sub 3/ --H/sub 2/O vapors are accomplished in a completely continuous relatively simple loop process. Product from the loop needs only dilution with water to be made suitable as feed for a solvent extraction processing plant. The proposed scheme differs from earlier… more

Experimental investigation of deposition by boron-containing fuels in turbojet combustor

Description: Report presenting an investigation conducted with trimethyl borate azeotrope and pentaborane fuels in a turbojet combustor. The primary purposes of the study were to determine the effect of boron oxide deposits on the turbine-nozzle area, combustor pressure loss, temperature distribution, and combustion efficiency. Three distinct boron deposit patterns were noted in the investigation.

Performance at High Temperatures and Pressures of an Annular Turbojet Combustor Having Articulated Liner Walls

Description: Report discussing the performance of an experimental quarter-sector annular combustor at conditions simulating supersonic flight of a cooled-turbine engine, as well as 20 different modification to the design. The final configuration was found to show no structural failures and little or no warping of liner parts after 40 hours of operation.

Heat Transfer in Regions of Separated and Reattached Flows

Description: Memorandum presenting the results of some investigations of separation on heat transfer and a method of reducing separation and shows the heat transfer in regions of separation and reattachment for a few specific shapes. The results show that heat transfer in a separated region is strongly affected by the extent of separation, the location of the reattachment point, and the location of transition along the separated boundary.

Flutter Experiments With Various Control Configurations

Description: Report discussing the flutter characteristics of several control-surface configurations, including a wing with tip ailerons, an all-movable stabilizer, vertical tails with trailing-edge rudders, a t-tail, and some simple models of all-movable controls. Some trends of the configurations and suggestions for improving the flutter characteristics are provided.

Free-Flight Skin Temperature and Pressure Measurements on a Slightly Blunted 25 Deg Cone-Cylinder-Flare Configuration to a Mach Number of 9.89

Description: "Skin temperatures and surface pressures have been measured on a slightly blunted cone-cylinder-flare configuration to a maximum Mach number of 9.89 with a rocket-propelled model. The cone had a total angle of 25 deg and the flare had a 10 deg half-angle. Temperature data were obtained at eight cone locations, four cylinder locations, and seven flare locations; pressures were measured at one cone location, one cylinder location, and three flare locations" (p. 1).

Measurement of Static Forces on Internally Carried Bombs of Three Fineness Ratios in Flow Field of a Swept-Wing Fighter-Bomber Configuration at a Mach Number of 1.61 With Illustrative Drop Path Calculations

Description: Report presenting a wind-tunnel investigation of bomb-release problems by measuring static forces for computation of bomb drop paths. Forces and moments were measured on bombs of three fineness ratios and on a swept-wing fighter-bomber configuration for several positions of the bomb under an open bomb bay. Results regarding contour paths and drop-path calculations are provided.

Investigation of an Air-Cooled, Plug-Type, Variable-Area Exhaust Nozzle

Description: Memorandum presenting an experimental investigation of the cooling requirements and internal thrust performance of an air-cooled, plug-type, variable-area exhaust nozzle in a turbojet-engine afterburner over a range of exhaust-gas total temperatures and exhaust-nozzle pressure ratios.

Effect of Hinge-Line Position on the Oscillating Hinge Moments and Flutter Characteristics of a Flap-Type Control at Transonic Speeds

Description: Free oscillation test to determine hinge moment of trailing-edge, flap control surface with various hinge-line positions at transonic speed. Results show that oscillating amplitude has a large effect on the control aerodynamic damping derivative and that the damping is unstable in the test Mach number range above about 0.90 for the hinge positions tested.

MOLTEN SALTS FOR CIVILIAN POWER

Description: Molten salts provide the basis of a new family of liquid fuel power reactors. The range of solubility of uranium and thorium compounds makes the system flexible, and allows the consideration of a variety of reactors. Suitable salt mixtures have meltirg points in the 85O to 95O deg F range and will probably prove to be sufficiently compatible with known alloys and to provide lorg-lived components, if the temperature is kept below 13OO deg F. Thus the salt systems naturally tend to operate in a t… more

Uniform Aqueous Corrosion of Aluminum--Effects of Various Ions

Description: The most important variable in water quality on the uniform corrosion of Al was the pH. Solutions of distilled water containing phosphate ions and citrate ions were the only media which showed a definite specific ion effect. Phosphate inhibited the corrosion and citrate increased it. Oxalate ions appeared to increase corrosion, but the effect is not definitely demonstrated by the data. Corrosion was dependent only on pH in tap water, reactor process water, distilled water, and distilled water c… more

Accident in Continuous-Dissolver Pilot Plant of Fluoride Volatility Project on May 15, 1957

Description: A series of explosions, estimated at five, occurred over a period of ten seconds within the continuous dissolver pilot plant, of the Fluoride Volatility Project on May 15, 1957. The explosive reactions occurred in the dissolver vessels as a result of violent chemical reactions between uranium and an interhalogen mixture. Just what the conditions were which triggered the explosions, have not been definitely established. Nevertheless, based upon the evidence which has been collected, several poss… more

EVALUATION OF GAMMA-RAY ATTENUATION TECHNIQUES FOR MEASURING THE DENSITY AND HOMOGENEITY OF THORIUM OXIDE SLURRIES CIRCULATING AT 300 C

Description: The feasftbility of using gamma -ray attenuation techniques was demonstrated in determining the density and homogeneity of slurries circulating at 300 deg C. The method appears to have general utility in the engineering studies of slurry because the equipment is mounted externally and does not interfere with the system under investigation. Two types of detector systems were evaluated for routine service. The decimal counter-recorder system was found more adaptable for rugged operations, whereas… more

COMPARISON OF ACTIVE AND INACTIVE URANIUM DIOXIDE-OXYGEN SYSTEMS

Description: Inactive UO/sub 2/ oxidizes at 180 deg C by tbe formation of a tetragonal oxide (U/sub 3/O/sub 7/), which is unsthble, on heating above 300 deg C. The U/sub 3/C/sub 7/ in compositions below UO/sub 2.25/ reacts with UO/sub 2/ to form UC/sub 2+x/ and U/sub 4/O/sub 9/. At compositions above UO/sub 2.25/, the tetragomal phase is stable to 600 deg C. In the homogenized condition, both U/ sub 3/O/sub 7/ and U/sub 4/O/sub 9/ are n-type conductors, while UO/sub 2+x/ is p- type. The solubility limit of … more
