THE EFFECT OF PRIMARY ALPHA ON THE BETA DECOMPOSITION OF ZIRCONIUM-URANIUM- OXYGEN ALLOYS

Description: The effect of primary alpha present during the solutiontreating cycle on the incubation period for the decomposition of beta and on the resultant structure has been determined for Zr-base alloys containing from 7 to 15 wt.% U and from 0.094 to 0.29 wt.% 0. Prior-existing alpha decreased the time at which precipitation of Widmanstgtten alpha started and increased the rate of precipitation. The microstructure of transformed alloys was correlated with tentative isothermal-transformation diagrams. … more

Preliminary Analysis of Hydrogen-Rich Hypersonic Ramjet Operation

Description: Report discussing findings on net thrust, fuel flow, and related performance indices for hydrogen-rich operation of nacelle-type and submerged ramjet engines at various Mach numbers. Testing concluded that the system could be helpful in a flight path involving acceleration from low to high flight speeds. Some trends of the effect of the operation conditions are noted, but no conclusions are drawn because of the preliminary nature of the report.

Radiation Stability of Organic Liquids. Semi-Annual Report No. 2 for 1 July to 31 December 1957

Description: When most solvents are exposed to radiation, decomposition occurs. The decomposition products may adversely affect the solvent extraction of uranium, thorium, or plutonium in a variety of ways. The current study is concerned with the (1) identification of the gaseous and liquid radiolysis products of tributyl phosphate, (2) the effects of such products upon uranium extractions and stripping efficiencies and thus on the efficiency of the Purex process for uranium and plutonium recovery.

Comments on the Angle of Repose of Aqueous ThO$sub 2$ Slurries

Description: aqueous thorium oxide slurries have arisen in connection with the design of the lower portion of the blanket pressure vessel and its associated piping. The literaiure review on the angle of repose of various dry solids by Mrs. B. S. Neumann in J. J. Hermans' book on''Flow Properties of Dispersed Systems'' is summarized. Mrs. Neumann points out that both a dynamic and static angle of repose have been observed with the angles for dynamic systems being larger than for static systems. Results are r… more

Fluidization in Tapered Beds

Description: Abstract: The concept of a tapered fluidized bed is explored briefly. Data are given showing that in bench scale apparatus a tapered bed gives better fluidization with some materials that are difficult to fluidize in a conventional cylindrical bed.

Prescoping Optimization for Selection of Enriched Uranium Gas-Cooled Power Reactor Design

Description: A preliminary set of performance calculations were made for enriched reactor cores based on five cylindrical vessel designs ranging from13 to 36 feet in diameter. The capital costs per kilowatt of electrical plant output as shown in Table II indicate than an economic optimum selection of pressure vessel size should be either the 25 foot or the 36 foot vessel.

The Compatibility of a Number of Metals and Alloys With Graphite

Description: The interaction between graphite and a number of metals and alloys was studied at 1850 deg F in 250-hr tests. Some materials were also tested at 1650 and 1850 deg F in 1000-hr tests. The graphite was heated in intimate contact with the test metal in welded metallic capsules. The exen of the reaction was judged on the basis of metallographic examinations and hardness traverses on cross sections of the reacted elements. Copper was the least reactive material tested in contact with graphite. Nicke… more

HRE-3 Blanket Heat Exchanger as a Feedwater Reactor Rather Than as a Steam Generator

Description: There may be an advantage to designing the HRE-3 vertical shell and tube slurry heat exchanger as a feedwater heater rather than as a steam generator from the standpoint of space requirement and blowdown problems. This study of the effect of this arrangement on the thermal efficiency of the heat-power cycle indicates that the gross electrical generating capacity of HRE-3 would be reduced by about 500-kw, or about 3 to 4% of the output. It is concluded that, (a) there is sufficient merit in usin… more

A PRELIMINARY SURVEY OF SOME FLUORIDE COMPOUNDS - II

Description: These two parts were issued separately, but are cataloged as a unit. The two compounds Na/sub 4/U/sub 3/F/sub 17/ and Na/sub 3/Th/sub 2/F/sub 11/ were found to have a face-centered cubic structure. From parameter dimensions and intensity values these two compounds appear to be isomorphous. Na/sub 5/U/sub 3/F/sub 17/ has an identical cell size with alpha -Na/sub 2//UF/sub 6/. A group of three compounds (Rb/sub 2/ThF/sub Rb/sub 2/ZrF/sub 6/, and CsZrF/sub 6/) were reliably identified as being uni… more

Application of neutron monitors to process control in Recuplex. Status report

Description: A program was. initiated early in 1957 to develop a neutron monitor capable of detecting plutonium (Pu) concentration in process vessels in Recuplex. This followed an earlier application by Finished Products Operation and Research and Engineering of neutron monitoring to powder counting which had been successful and was being regularly used. The process vessel monitoring was to be done by the ``in tank probe`` method, utilizing the monitored solution as its own-moderator, and detecting the resu… more

Correlation of Polarographic Walf-Wave Potentials With Nuclear Magnetic Resonance "Chemical Shifts." Parallel Correlation With Chemical Reactivity Parameters. Report No. 35

Description: Since nuclear magnetic resonance ''chemical shifts'' are considered to be good measures of electron densities in molecules, the extent to which they can be correlated with the polarographic half-wave potentials of organic compounds has been surveyed. To extend the applicability and interpretation of the proposed correlation, parallel correlatioan of E, with Hammett's sigma and Taft's sigma parameters were made, since both of the latter are also regarded as indication of electronic distrinution … more

Effects of Boattail Area Contouring and Simulated Turbojet Exhaust on the Loading and Fuselage-Tail Component Drag of a Twin-Engine Fighter-Type Airplane Model

Description: "An investigation of a twin-engine fighter-type airplane model has been conducted in the Langley 16-foot transonic tunnel to determine the effect on drag of a fuselage volume addition incorporating streamline contouring and more extensive boattailing of the engine shrouds. The effect of hot exhausts from the turbojet engines was simulated with hydrogen peroxide gas generators using scaled nonafterburning engine nozzles. Afterbody pressure distributions, base drag coefficients, and forces on the… more
