Bromine Exchange in Graphite-Bromine Lamellar Compounds

Description: A kinetic study of the exchange of normal and radioactive bromine in graphite-bromine lamellar compounds has been made at temperatures of 30° to 50°C. Natural and synthetic graphite powders were investigated. Two alternative mechanisms for the exchange, volume diffusion and surface exchange, were considered. The data were in better agreement with the diffusion mechanism. Diffusion coefficients of 10 -9 to 10 -8 cm2/sec and an activation energy of 11 to 14 kcal/mole were calculated for the natur… more

Buckling Measurements : Heavy Natural Uranium Tubular Fuel Assemblies

Description: One-region buckling measurements that were made on a series of D/sub 2/O- moderated lattices of heavy uranium metal tubes in the Process Development Pile at Savannah River Laboratory are presented. The purposes of these measurements are to provide normalization points for lattice bucklings and to extend the study of natural uranium- D/sub 2/O systems. The dependence of buckiing on the moderator-to-fuel ratio is studied for two types of lattices.

Bucklings, Disadvantage Factors, and [Delta]28 Measurements in Some Undermoderated Slightly Enriched Cores

Description: The reactivity lifetime of a water-moderated, thermal, power reactor using a low enrichment fuel is, in part, dependent upon the conversion ratio. The High Conversion Critical Experiment (Hi-C) was initiated at Argonne to extend the rage of investigations with light water moderated, slightly enriched, oxide-fueled cores. Bucklings were obtained from the clean critical core size and reflector savings values. The so-called "integral" technique was used to measure the disadvantage factor.

The Calculation of Crystal and Counter Settings for the Collection of Crystallographic Data with a Counter-Diffractometer in the Equatorial Plane

Description: Formulas are developed for the angle between any two vectors lying in a plane through the origin of reciprocal space. The application of these formulas for computing the counter and crystal angles for the collection of data with a counter-- diffractometer in the equatorial plane is developed, and a suitable computer program, written in FORTRAN without format suitable for an IBM 1620 computer, is described.

The Calculation of Zero-Point Energies of Molecules by Perturbation Methods

Description: Two methods are proposed for calculating zero-point energies of molecules. The first makes use of the fact that one can easily write down the quantum mechanical Hamiltonian for a vibration system. The zero-point energy can then be obtained by a perturbation scheme without solving the secular equation. The second method requires a knowledge of the normal modes and frequencies of a reference molecule, but then enables one to calculate isotope effects by a perturbation scheme. The methods are appl… more

Carolinas Virginia Tube Reactor: Large Plant Study

Description: From introduction: The Carolinas Virginia Tube Reactor is to be designed as a prototype for a large-scale plant of about 200 megawatts electrical or larger, wherein operation with natural uranium feed material may be feasible but such feed material can only be considered if it is the more economical.

Cell Population Kinetics of an Osteogenetic Tissue, I

Description: Cell proliferation on the actively growing periosteal surface of the femur of rabbits aged two weeks, has been investigated using autoradiographic techniques. Injections of tritiated glycine and tritiated thymidine were given simultaneously and the animals sacrificed at intervals from one hour to 5 days after injection. The glycine labelled the position of the bone surface at the time of injection and the thymidine labelled the cells which were synthesizing DNA . The rate of increase in the cel… more

Cell Population Kinetics of an Osteogenetic Tissue, II

Description: A study of the cell kinetics on the actively growing periosteal surface of the femur of rabbits ages two weeks has been continues. A single injection of tritiated thymidine was given and the rabbits killed from one hour to four days after injection. The grain count spectra of the different cell types, pre-osteoblast, osteoblast and osteocyte, have been compared at different times after injection. The results showed evidence for the uptake of thymidine in nuclei which is not associated with cell… more

The Cellular Differences Between Acute and Chronic Neutron and Gamma Ray Irradiation in Mice

Description: It has been well established that even small doses of radiation will shorten life expectancy of animals, and that in general the causes of death are the same for the irradiated as for the normal animals. When x or γ rays are compared with neutrons in their ability to shorten the life span, some interesting differences appear. All available data from different laboratories on the shortening of the life span by x or γ on the one hand and neutrons on the other, have been compared. In spite of the … more

Cenozoic Geology in the Mammoth Area Pinal County, Arizona

Description: From introduction: "The purpose of this report is to show how mapping of discrete units of the valley fill may lead to a broadened understanding of Cenozoic history of intermontane basins in Arizona. The area described is in the vicinity of Mammoth Arizona where deep dissection has exposed a complex sequence of terrestrial deposits and related rocks."

Chemical Binding in the Water Molecule

Description: From Introduction : "This analysis partitions the electron density and the electronic pair density of the molecule into components corresponding promoted atomic states, to quasiclassical coulombic interactions of these promoted states, and to interactions resulting from the sharing of electrons between atoms."

Chronic Excess Salt Consumption as an Etiologic Factor in Human Hypertension

Description: Since 1940 it has been known that extra salt (i.e. sodium chloride) facilitated the development of experimental hypertension induced by various sterols; subsequently hypertension was induced by desoxycorticosterone acetate plus sodium chloride; then hypertension was produced by using hypertonic saline as the sole source of liquid; and finally, in 1953, Menesly and his associates reported that chronic ingestion of excess dietary salt alone would produce hypertension in rats. Furthermore, in conf… more

A Cladding Failure Monitor for Liquid Metal-Cooled Reactor Systems

Description: A cladding failure monitor using the principle of detection of rare gas fission products in the cover gas system of liquid metal-cooled reactors, was developed which efficiently discriminates against AR41. This discrimination is accomplished by electrostatic precipitation of the rare gas daughter nuclides; since K41, the daughter of Ar41, is not radioactive, the activity of the precipitation is chiefly due to decay of various Rb and Cs fission products. The monitor equipment is described. Resu… more

The Class of Shocks With Uniform Pressure

Description: If a piston with constant velocity moves into a shock tube containing material at rest and at uniform density, the result is well known and trivial. The shock propagates with uniform speed, the state and speed of the material behind the shock is constant. One can ask if similar flows exist for cylindrical of spherical symmetry. Quickly one rules out the possibility of a solution which retains all the properties of this trivial solution. One asks if there are any solutions such that the material… more
