Development of a Ti-Al-Cb Alloy for Use at 1200-1800 F
>Titanium-base alloys containing major amounts of Nb and Al are being studied to develop new high-temperature alloys of low density. Findings derived from the preparation and examination of quaternary alloys containing small additions of Sn, Hf, or Zr; high-purity ternary alloys, and ten-pound melts of Ti-l5Nb-10A1 and Ti-l7.SNb-l5Al are presented. In a number of alloys, improved tensile properties and oxidation resistance resulted from the addition of Sn, Hf, or Zr, and in some instances very high strength-density ratios were maintained up to 1800 deg F. The properties of highpurity alloys were similar to those of alloys prepared with sponge Ti. It is recommended that further effort should be directed toward the more highly alloyed compositions, including those containing Hf and Zr. (auth)

Holweck Type Mollecular Pump
The general design of a Holweck-type molecular pump is considered. The design consists of a stationary helical pumping groove cut inside a cylindrical bore and a closely fitting smooth cylindrical rotor spinning concentrically inside this housing. Approximate analytical expressions were obtained for the pumping speed and ultimate pressure ratio of this type pump. (J.R.D.)

HIGH TEMPERATURE OXIDATION RESISTANT COATINGS FOR TANTALUM BASE ALLOYS
Aluminide and beryllide coatings were investigated for tantalunn, a binary Ta-10 W alloy, and a ternary alloy, Ta-10 Hf-5 W. Coatings were applied by dipping, packing, cold spraying, and vapor deposition. Oxidation resistance was evaluated by furnace testing, resistance heating, and flame testing. Internal hardening and diffusion effects were also studied. A Sn-Al coating was developed that had excellent oxidation resistance for 10 hours to at least 3000 deg F. Evaluation was extended to arc-plasma tests, which also showed the feasibility of protecting molybdenum and tungsten. A similar investigation was performed with a Nb alloy, which could be protected to 2500 deg F for at least 10 hours. (auth)

A Parametric Study of Certain Low-Molecular-Weight Compounds as Nuclear Rocket Propellants. v. Methane
A parametric investigation was made of a series of lowmolecular-weight, high-hydrogen-content compounds as propellants for nuclear-powered rockets. The chemical compounds include H/sub 2/, NH/sub 3/, H/sub 2/0, LiH, CH/sub 4/, and CH/ sub 3/OH. A two-part computational program was carried out for each compound; the results for methane are presented in both tabular and graphic form. The results of the first part of the program are presented in static form, that is, by the conventional Mollier diagram, in which specific enthalpy is plotted against specific entropy, with cross plots of temperature, pressure, and molecular weight. The results of the second part of the program are presented in dynamic form by a series of diagrams in which specific impulse is plotted against pressure, with cross plots of chamber temperature, exhaust temperature, and rocket-nozzle area. It was assumed that the propellant gas, starting with a nonzero chamber velocity, maintained instantaneous chemical equilibrium composition as it expanded isentropically through a de LavaI nozzle.

Bobcat (Program No. 56) Code Preparation Analysis on the IBM-650
The BOBCAT code that is programmed for the IBM650 is described. The code facilitates the nuclear analysis of APPR-type cores by performing many of the routine calculations necessary to obtain input to various IBM-650 and IBM-704 codes. Using fuel element geometry and U/sup 235/ and B/sup 10/ loadings as input, the code prepares input to the MUFT-III and various P/sub 3/ codes as output; in addition, a large amount of detailed descriptive core data that is useful in nuclear analysis calculations is generated.

Process Vessel Design for Frozen-Wall Containment of Fused Salt
The feasibility of the containment of a molten sodium fluoride- zirconium fluoride salt at 550 deg C in vessels with a protective inner liner of frozen salt of the same composition was demonstrated. Two different designs were used for supplying internal heat directly to the molten salt: induction heating and electrolytic heating. The test equipment was of a size practical for processing zirconiumuranium alloy reactor fuel by the Fused Salt Process. (auth)

PERFORMANCE TESTS OF SNAP 10A THERMOELECTRIC ELEMENTS
Apparatus for the performanee testing of SNAP 10A thermoelectric elements was designed, constructed, and is now in operation. Elements may be tested for any desired length of tfme up to 1400 deg F and in a vacuum of 1 x 10/ sup -5/ of Hg. The equipment used for these tcsts may also be utilized for measuring Seebeck coefficient and resistance as a function of temperature. Element performance is derived from the data on voltages and temperatures. The performance variables which are reported in graphic form are as follows: loaded output voltage at any desired DELTA T; open circuit output voltage at any desired DELTA T; power output under optimum load conditions; current produced under matched load conditions; and internal resistance of the element.

Status Report No. 1 on Clinch River Study
A study of the Clinch River below Oak Ridge National Laboratory was initiated in Feb. 1960 to obtain fundamental information on the physical, chemical, and biological dy namics of this fresh-water stream which receives large volumes of low-level radioactive wastes. The fate of radioactive materials discharged to the river, the mechanisms of dispersion of radionuclides released to the river, the direct and indirect hazards of current disposal practice in the river, and the over-all usefulness of this river for radioactive waste disposal purposes will be studied. In formation obtained will have important implications for problems involving large-scale environmental contamination such as the over- all diluent capacity of fresh-water environments for the continuous input of large volume low-level radioactive wastes and the long-term indirect impact of radioactive contamination on such an environment. White Oak Creek, which drains the site ot Oak National Laboratory, flows into the Clinch River, a tributary of the Tennessee River. The Clinch and Tennessee Rivers are described and available data on the physical, chemical, and biological conditions of the rivers are summarized. Data are included from preliminary studies on the properties of water and bottom sediments, studies on radionuclide interactions with minerals and river sediment, biological studies …

TWO-PHASE PRESSURE DROP IN A NATURAL CIRCULATION BOILING CHANNEL
Experimental two-phase pressure drop data were obtained from a 1/4 x 2 x 60-in. vertical, uniformly heated, test section. The local volume fraction of steam was measured simultaneously with the pressure drop, thus allowing separation of the terms for hydrostatic and acceleration pressure drops from the over-all static pressure drop. The results are expressed in terms of an averge two-phase friction factor multiplier, R = DELTA P/sub TPF// DELTA P/sub L/O/sub ,/ and are co mpared with the Martinelli-Nelson correlation, the LottesFlinn correlation, and a correlation combining that of Martinelli-Nelson and a flowrate parameter. The ranges of variables include: pressure from 150 to 600 pstg; power density from 17.2 to 94.5 kw/liter of coolant; sub-cooling from 4.8 to 25.7 deg F; exit qualities from 0.009 to 0.065; exit steam volume fraction from 0.19 to 0.77; and velocities from 2.56 to 3.43 fps.
