Some fundamental aspects of vaporization
A discussion of the fundamental aspects of vaporization is presented along with a discussion of evaporation within the theories of solids and gases. Suggestions are offered as to where assumptions might be introduced to describe the phenomenon more completely, and tenative definitions concerning factors which can give rise to vaporization coefficients are given. An effort is made to unify these concepts within the phenomenological framework of irreversible thermodynamics. (J.R.D.)

Automatic processing system for film badges
A semiautomatic film badge system was developed to process dosimeter film faster and more reliably than the previously used manual method. The films are automatically loaded and unloaded from the badges and marked with identifying numbers, manually developed, and automatically read. The resultant information is punched into IBM cards.

Fuel Elements for the Argonne Advanced Research Reactor
The core design and the fuel element concept for the high-flux Argonne Advanced Research Reactor are presented. The core is cooled and moderated by light water and utilizes beryllium as a reflector. The fuel element assembly is rhomboidal in cross section and consists of 27 plates fastened together at their edges by dovetailed locking keys, and at each end by end fittings. Each fuel plate is 40 mils thick and contains a uniform dispersion of highly enriched UO/ sub 2/ particles, up to a maximum of 37 wt%, in a matrix of sintered stainless steel powder. A 5 mil thick stainless steel cladding is metallurgically bonded to each side of the fueled matrix. (N.W.R.)

Experimental Cesium Line Shapes
In partially-ionized cesium plasmas above 10/sup 13/ ionscm/sup -3/, the plasma-broadened lines are easily measured and can be used as a simple diagnostic method for the determination of ion density, once the width versus ion density relationship is established either theoretically or experimentally. Measured line widths are presented and results are compared with theoretical widths. The profiles of various lines of the sharp, diffuse, and fundamental series lines of cesium were measured at known ion densities with a scanning monochromator on a hot-cathode parallel-geometry cesium diode. For each case, the ion density and the electron temperature were determined by measuring the intensity of the radiative recombination continuum. Line intensities gave independent measurements of temperature that were in agreement with electron temperatures, showing the existence of local thermodynamic equilibrium and providing a confirmation of ion density through the application of the Saha equation. Detailed results of line width measurements are presented for a range of plasma density from 3.2 x 10/sup 13/ to 1.6 x 10/sup 15/

Letter from Arthur M. Alpert to Messrs. Texas National Petroleum Co. referring to the letter of October 31st, regrading the first liquidation which was directed to Mr. Marion Lee Kempner. But he mentions that Kempner's file does not reflect that he's ever received the letter of May 9, 1962. So, he requests them to send a copy of it, so Kempner's records would be complete.

A Fuel Reprocessing Plant for Fast Ceramic Reactors
A study was made of the adaptation of the HAPO anion exchange process to the reprocessing of Fast Ceramic Reactor (FCR) fuel using the Idaho Small Plant Concept. It is shown that the anion exchange flowsheet meets the reprocessing objectives of the FCR case and can be adequately accommodated in the Small Plant Concept. Capacities of up to 1550 Md(e) are feasible in the Small Plant and unit reprocessing costs range from 0.14 to 0.28 mills/kwh depending on the number of reactors to be processed. (auth)

Meteorites and the Early History of the Solar System
The early thermal history of meteoritic matter is discussed. Clues obtained from the mineralogy of the carbonaceous chondrites are described. An attempt was made to establish the origin of the high-temperature minerals that served as the starting material for carbonaceous chondrites and the possible settings for the aqueous stage of the minerals. The occurrence of primordial noble gases in the meteorities is discussed. Chemical fractionations in the chondrites, extinct radioactivity, and general isotopic anomalies are also discussed. A series of possible events in the history of the solar system, based on the conditions discussed, is presented. (M.C.G.)

Kinetic Studies of the Reactions Occurring Between Tungsten and Gases at Low Pressure and High Temperatures
Oxygen, nitrogen, and nitric oxide gases were passed through a system consisting of a tungsten filament, an ion gauge, and a mass spectrometer. The ion gauge recorded total pressures and the spectrometer recorded partlal pressures of O/sub 2/, N/sub 2/, NO, CO, COa, and H/sub 2/O. From the way these pressures changed with filamert temperature, the rates of conversion of O/sub 2/ to volatile tungsten oxides and O, and of NO to volatile tungsten oxides N/sub 2/ , O/sub 2/, and O were computed. The time rate of resistance change in the filament was used to compute the rate of conversion of tungsten to tungsten oxides. The filament temperatures ranged from 1950 through 2600 deg K and gas pressures ranged from 10/sup -8/ to 10/sup -6/ atm. For the tungsten-oxygen reaction, the rates of tungsten and oxygen loss were found to depend upon oxygen atom concentration on the surface. The rate of oxide power, depending upon the concentration of oxygen atoms on the surface. The reaction rate at constant oxygen pressure decreases with increasing temperature. For calculational purposes, the tungsten oxygen gas moleeules were assumed to be WO/sub 3/ only, though WO/sub 2/ and WO are other possible products. The …

Transient Analysis of Two-Phase Natural-Circulation Systems
The design of high-performance natural-circulation boiling systems requires that the behavior of the systems be characterized under transient conditions. In order to accomplish this, the time- and space-dependent continuity, energy, and momentum equations for a natural-circulation system are written. This publication presents a technique for solving the equations of a natural-circulation system. The solutions are compared with experimental results at various pressures with two geometries in boiling water systems. The solutions meet the established criteria. The analog model is useful for predicting the behavior of twophase natural-circulation systems during transients. The model accurately predicts the point at which such systems exhibit osciilatory behavior. The results were found to be sensitive to the vapor-liquid velocity ratio (slip ratio) used in the computation. The velocity ratio correlation used in the model is presented. All computations, circuits, and operating irformation necessary to duplicate the experiment are given. (auth)

TRANSMISSION ELECTRON MICROSCOPY OF URANIUM
A technique for the thinning of U for transmission electron microscopy is described. The main difficulty was the removal of the anodic film that formed during electropolishing. However, excellent electroplating results were obtained with a solution of 800 cc ethanol, 500 cc ethylene glycol, and 500 cc H/sub 3/PO/ sub 4/(85%) with the U cathode at 30 ma/cm/sup 2/ and room temperature. The anodic film that formed was then removed by electropolishing in a solution composed of 75 cc H/sub 2/SO/sub 4/(98%), 7cc H/sub 2/O, and 18 cc glycerol with a Pt cathode at 6 v between 0 and 5 un. Concent 85% C. Examples of the structures that were seen in samples prepared in the solutions by the window technique are illustrated. (P.C.H.)
