Quarterly summary report of studies conducted through the Radiation Laboratory, University of California. Some results reported in the report may be of a preliminary or incomplete nature.

A short survey of some of the metabolic relationships of the elements, cerium, colurbium, plutonium, strontium, yttrium, and zirconium is presented. While the results of internally deposited radium have not been investigated in these experiments, they have been extensively studies by others. Because so much is known of its biological effects, it has been included in this historical survey.

Technical report outlining the physical operability of 30% tributyl phosphate in a hydrocarbon dilutent for the extraction of uranium from more feed slurries. Operability had been satisfactorily demonstrated in jet mixing columns at the pilot plant of the Mallinckrodt Chemical Works. [From Abstract]

Helium, carbon dioxide, and helium-carbon dioxide mixtures are being considered for use as the pile gas in `G` pile. Coring the graphite tube block to provide a gas gap between the process tube centered in the graphite and the graphite tube block has been suggested as a means of maintaining high graphite temperatures in the tube blocks. It has been established that graphite damage during irradiation in minimized at high temperatures.

The following report follows a test with the purpose of determining the effect upon image fidelity by exposing a television camera to high intensity radiation over an extended period. Provided later in the report are notes on the design of the utiliscope camera used for these tests due to notable design features.

The following document describes x-ray diffraction measurements for an approximate crystal structure for the beta phase of metallic uranium.

At the request of the A.E.C., experiments were conducted on the continuous addition of liquid UNH to a bed of powdered UO{sub 3} in a gas heated pot in the Pot Room of Plant 6 to gather thermal data regarding the continuous decomposition of UNH and to make observations of the physical behavior of such a system. The thermal data indicate that the size and the energy requirements of the equipment required per pound of UO{sub 3} produced would be considerably smaller than for the present batch-wise process. The products of the reactions through all the successive stages were more dense than the products of the present process. The metal yields in the reduction stage were 98.5%, 97.6% and 97.8%. The yield of 98.5% in the one reactor indicates that this process will produce UF{sub 4} capable of producing as high yields as any yet made. The lower yields in the other two cases fall within the present control limits for yield. The determination of the physical and chemical properties has not yet been completed and will be reported shortly in a subsequent paper.

From Summary: "Flight tests have been conducted on rocket-propelled models of an airplane configuration incorporating a sweptback wing with inverse taper to investigate the drag, stability, and control characteristics at transonic and supersonic speeds. The models were tested with a conventional tail arrangement in the Mach number range from 0.55 to 1.2. In addition to the various aerodynamic parameters obtained, the flying qualities were computed for a full-scale airplane with the center-of-gravity location at 18 percent of the mean aerodynamic chord. Also, included in this investigation are drag measurements made on relatively simple fixed-control models tested with both conventional and V-tail arrangements."

From Introduction: "V-g records supplied the NACA by the Bureau of Aeronautics in 1948 and 1949 have provided additional material. These records are analyzed statistically in this report to the frequency of large values of acceleration and airspeed, and results are compared with the design requirements."

An investigation was conducted in the NACA Lewis altitude wind tunnel to determine the effect of compressor-outlet bleedoff on the performance of an axial-flow turbojet engine equipped with a variable-area exhaust nozzle. Results presented indicate the effect of compressor-outlet bleedoff on performance at altitudes of 25,000 and 40,000 feet and a flight Mach number of 0.53. Variation of performance with bleedoff flow is indicated for operation with fixed- and variable-area exhaust nozzles. Temperature and pressure losses through the bleedoff ducting system are also discussed.
