Vacuum Casting of Aluminum-Silicon Coating on Tuballoy Uranium . Final Report on a Part of p.A. No. 390-Ml-54-S f.s. 17
Welding is used to fabricate titanium and titanium-alloy components for air-frames, Jet engines, missiles, and chemical equipment. Annong the most important considerations in adapting titanium and its alloys to welded components is to use proper welding procedures and to select alloys that have the required weld-joint properties. The chemical and metallurgical characteristics that affect the selection of welding processes and alloys are discussed. Also, information is presented on surface preparation, welding procedures, and quality control. In addition, detailed data on the mechanical properties of welded joints in the commercial grades of titanium and titanium alloys and how these properties are affected by heat treatment and elevated temperatures are presented.

A Homogeneous High Temperature Power Pile Utilizing Graphite Which Has Been Impregnated With Uranium
Thermal reactors that have a significant fraction of fissioning occurring just above thermal energies are studied. First, the thermal neutron diffusion equation is corrected for fast fission effects. The resulting diffusion equation is shown to be equivalent to the Fermi Age equation corresponding to the same physical assumptions. Next, the one delayed neutron group kinetic equations for the corrected thermal flux are given, and the life time of the thermal neutron is corrected by the average slowing down time. (auth)

Graphite expansion committee meeting of January 10, 1947
The thirteenth meeting of the Graphite Expansion Committee was held on January 10, 1947. A summary of meeting topics follow. The horizontal bowing of Tube 4494-D in the top corner of the pile is considerably greater than the bowing which can be attributed to graphite expansion at this elevation in the pile, indicating that the top layers of graphite are being dragged outward by expansion of the underlying layers. Such a phenomenon could shear the vertical thimbles at a point just below the thermal blocks. Equipment is to be developed for measuring any eccentricity between the rod guide and a section of the thimble located just below the end of the guide. Jacking tests using forces up to 4000 lbs. on gun-barrels which show binding have demonstrated that binding is still present at these high forces. It was recommended that no further jacking tests be performed on gun-barrels which are known to exhibit binding. Rupture tests on Tube 4082-B caused failure of the rear Van Stone joint after the tube had been stretched {1/2} inch. The amount of tube stretch before failure of the flames will probably be affected primarily by corrosion of the flange and, for the same reason, …

Analytical requirements of the 234-5 Project
At this time it is desirable that preliminary estimates be made of the manpower, equipment, space, layout and facility requirements of the analytical section for the 234-5 Project. To arrive at these requirements a rough estimate of the required analyses, their scope and their frequency has been compiled. This is expected to serve as a basis for the Laboratories Division to outline their space and equipment requirements as soon as possible and to assemble the required personnel for operation later. Crucial elements encountered in the process are classed as light impurities or as metallurgical impurities. The light elements are undesirable due to the {alpha}, n reaction with plutonium. The metallurgical impurities are undesirable since they change the physical properties of plutonium. The light elements undesirable in the finished product and the approximate tolerances (in ppM of plutonium) acceptable for each are listed assuming all other elements listed are absent. A list of the undesirable metallurgical impurities with the tolerances (again expressed in ppM of plutonium) for each element, assuming the other elements are absent are given.

Inspection and replacement of Van Stone flanges, B, D, and F piles
Routine inspections of selected Van Stone flanges have been made at all three piles since start-up. In September, 1947, these inspections indicated that corrosion effects were becoming dangerously severe. Some of the flanges appeared to be corroied and pitted to a depth of two-thirds of the original flange thickness. To determine the extent and severity of the corrosion, residual flange thickness measurements were made on the flanges of about 64 scattered tubes. Included were front and rear flanges of tubes from all four orifice zones. Results of the survey indicated the immediate need for an extensive repair program to preclude the possibility of failure of some of the flanges.

Analysis of urine samples for iron and S{sup 35}
On August 21, 1948, several smear samples of contamination from the inner rod room at 100-F Area were submitted for beta identification. This contamination was spread as a result of maintenance work on the horizontal rods. Urine sample were deemed advisable for two men who had been exposed while working on the rods. These urine samples were also submitted for beta analyses. The analyses of the smears showed the contamination to consist of primarily S{sup 35} (65%) and Fe{sup 59} (30%)and minor amounts of Ca (5%) and C{sup 14} (3%). No significant amount of radio iron or sulfur was found in either the feces or urine samples.

An Isotope Effect in Photosynthesis
In the course of some kinetic studies on photosynthesis of barley seedlings, it has been found that plants utilize C{sup 12}O{sub 2} faster than C{sup 14}O{sub 2}. The plants were placed in a closed system containing an infra-red absorption-cell for the analysis of total CO{sub 2} and an ionization chamber for the determination of C{sup 14}O{sub 2} in the gas phase, both instruments recording continuously. Carbon dioxide, containing about 2% C{sup 14}O{sub 2}, was introduced in the dark and the specific activity at this point taken as unity. After a short dark period, the lights were turned on and photosynthesis was allowed to take place. A figure shows the result of a typical experiment. During the initial dark period the specific activity fell because of dilution by inactive respired CO{sub 2}. However, as photosynthesis proceeded, the specific activity of the residual CO{sub 2} rose until, when only 1/6 of it remained, the specific activity reached a peak some 20% higher than it had been at the start of photosynthesis. At this point the steady respiratory dilution became an appreciable fraction of the total remaining CO{sub 2}, and the specific activity dropped rapidly.

Limitations and past applications of the cloud chamber
The cloud chamber is a means of observing the path of ionizing radiation. It does not reveal the radiation directly, but gives a visible trail of the path along which the radiation has traveled. The trail is formed by vapor condensing upon pairs of ions remaining after an ionizing particle has passed through the medium. The mutual interaction among rays, atoms, nuclei, and particles, can be studied and measured with the aid of vapor trails. Measurements of changes in direction and range as recorded on the photographs may be interpreted in terms of changes in momentum and energy of the particles in these reactions. To obtain a precision measurement is difficult with a cloud chamber. The dependence of the apparatus upon a sudden gas expansion is certain to create distortions resulting from turbulence. Furthermore, since any radiation is subject to variations, precision measurements can be obtained only be the collection of numerous observations for statistical analysis. This document details the design, operation, and limitations of cloud chambers.

Redox Committee: Conference notes and recommendations, meeting of June 23, 1949
Topics discussed include gang valve substitute devices; cost of lining cell bottom with stainless steel; and the pump development program. [The Redox plant used a reduction-oxidation process for fuel separation that allowed recovery of uranium as well as plutonium for the first time. It succeeded earlier plants (T and B) that had used methods based on the bismuth phosphate process that recovered only plutonium.]
