Equipment description of proposed RDA-5 canning machine

Description: The General Engineering Laboratory has submitted a cost estimate and a proposal covering the design, fabrication, construction, and testing of a uranium slug canning machine. This machine will cover requirements for mechanization of only the operations occurring within the aluminum-silicon canning bath. These operations are: Can and cap preheating, Can and cap wetting, Canning assembly, and Quenching. Stated briefly, the machine is required to insert a prepared uranium slug into an aluminum can and close the can opening with an aluminum cap. All assembly operations will be carried out beneath a molten bath of standard Hanford aluminum-silicon bonding alloy. The uranium slug is preheated and prewetted before being manually transferred to the slug assembly and quench machine. The process performed by the machine will be integrated with the manual slug preheating and wetting equipment so that proper preheating and wetting is attained before the slug is inserted into the machine. After assembly the completed canned slug will be transferred to the water quenching station, where the components are held firmly together until the molten aluminum-silicon has frozen, forming a homogeneously bonded assembly. This report provides a detailed description of the machine.

Description: The over-all objectives of this project encompassed testing the suitability of standard and special laundering methods and standard equipment for field decontamination of clothing; evaluating the contaminability and decontaminability of selected fabrics, and testing of experimental clothing monitoring instruments. Garments and fabrics contaminated by controlled methods were used during the operation for testing the equipment and evaluating fabrics and formulae. 8tandard Army laundering methods and equipment, including wooden washers, were effective for decontaminating clothing in the field. A decontaminating laundry formula employing citric acid and tartaric acid followed by either an organic or inorganic chelating agent results in a higher degree of decontamination than other formulae tested. The standard Quartermaster Corps mobile field laundry formula resulted in satisfactory decontamination with the type of soil and activity encountered and the cost of supplies is approximately one-tenth as much as the special formulae. Woolen garments and fabric swatches were decontanninated by laundering as readily as cotton or synthetic fabrics. Clothing monitoring instruments under development appear suitable for monitoring clothing under field conditions to determine the degree of contamination both before and after precessing. (auth)

Nuclear Thermodynamics of the Heaviest Elements

Description: The phenomenon of alpha particle emission, a general observable property for the nuclides above lead, makes it possible to relate these nuclides energetically. The radioactive decay energy along a radioactive series can be summed so that the total decay energy for each nuclide in the series is known with respect to its position above teh bottom of the series, that is, with respect to its terminal lead (or bismuth) isotope. This can be done for each of the four mass types and, as shown, one can obtain this information for all the collateral members as well as the members in the main line of decay. Thus it is possible, using the relation between mass and energy and the known mass of the alpha particle, to convert this radioactive decay energy ine ach case to a relative mass value based on the mass of one of the four end products, Pb{sup 208}, Pb{sup 207}, Pb{sup 206}, or Bi{sup 209}. If the absolute mass of each of these is known, it is then possible to calculate the absolute mass for all the heavy nuclides above lead for which decay energy data are known or can be estimated. The absolute mass of only one of this group of four need actually be known since the neutron binding energies related them can be measured. it is also possible to measure the absolute masses of other nuclei in each of the four series, for example, such nuclides as U{sup 238}, Th{sup 232}, U{sup 235}, or Np{sup 237} which are available in sufficient quantity for mass spectrographic measurements, and the aboslute masses of the other members of each of the series may then be calculated from these through proper use of the decay data. if the absolute masses of more than one member of the same ...

The Crystal Structures of NpC and Pu2O3

Description: NpC and Pu{sub 2}O{sub 3} have been identified by x-ray diffraction. NpC is face-centered cubic, NaCl structure with a = 5.004 {+-} 0.005 A Pu{sub 2}O{sub 3} is isomorphous with the hexagonal ''A form'' for the rare earth sesquioxides with a = 3.840 {+-} 0.004 A; c = 5.957 {+-} 0.006 A and has essentially the same atomic parameters at La{sub 2}O{sub 3}. The lattice dimensions are smaller than predicted for pure Pu{sub 2}O{sub 3}, implying that the average oxidation number of plutonium is between (III) and (IV).

Abstract of Paper Presented at the Symposium on Metal ChelateChemistry at Brooklyn Polytechnic Institute on April 26, 1952

Description: The essential structural element which differentiates metal chelate compounds from metal coordination compounds, or metal complexes in general, is the existence of some linkage between two or more of the donor atoms in the first coordination sphere of the metal. It is the purpose of the present discussion to examine the influences that this structural factor may have upon the physical and chemical properties of chelate compounds. Examples of well known, simple coordination compounds involving a variety of donor atoms (Oxygen, nitrogen), as well as a variety of electrostatic situations are shown in the following formula. Below each one are listed a few corresponding chelate structures.

Activation Energy for Fission

Description: The experimentally determined exponential dependence of spontaneous fission rate on Z{sup 2}/A has been used to derive an expression for the dependence of the fission activation energy on Z{sup 2}/A. This expression has been used to calculate the activation energy for slow neutron induced fission and photofission. The correlation with the experimental data on these types of fission seems to be quite good.

Interpretation of High Energy p-p Scattering.

Description: High energy p-p scattering has been interpreted by several authors in terms of highly singular noncentral interactions. The triplet state calculations were carried out in the Born approximation and, together with the singlet, yielded an almost isotropic (c.m. system) differential cross section. Agreement with experiment was good at large angles but the theoretical peak in the forward direction, due mostly to singlet d scattering, was too large. It is not clear however that the Born approximation should be valid for singular potentials.

The Path of Carbon in Photosynthesis, XV. Ribulose andSedoheptulose

Description: The intermediates of carbon dioxide reduction by plants include phosphorylated derivatives of hydroxy acids and sugars. Their identification becane possible when the use of labeled carbon dioxide permitted discrimination between the earliest products and the many other components of photosynthetic tissues. A number of compounds were identified by virtue of the chemical and physical properties of the radioactive compounds in tracer amounts and by direct comparison of these properties with those of suspected known metabolic intermediates. It became apparent that several labeled compounds found in short exposures to radioactive carbon dioxide were not substances previously identified as metabolic intermediates. Two phosphate esters in particular were observed in the products of the first few seconds of steady-state photosynthesis by all the photosynthetic microorganisms and higher plants examined in this laboratory. These esters have been isolated by paper chromatography in tracer quantities and enzymatically hydrolyzed to give two sugars, ribulose and sedoheptulose. This paper contains a description of the chemical identification of these sugars and some observations and suggestions regarding the function of their esters. The general importance of these compounds in photosynthesis was surmized before their identification. The products of photosynthesis with C{sup 14}O{sub 2} by each plant included phosphate esters of the same two then unknown compounds in addition to those of the expected glucose, fructose, dihydroxyacetone and glyceric acid. As the time of steady-state photosynthesis in C{sup 14}O{sub 2} decreased, the fractions of total fixed radiocarbon in the esters of the two unidentified compounds increased.
