Some Comments on the Ioffe Experiment

Description: A recent paper by Ioffe et al. indicates the presence of an additional loss mechanism (other than charge exchange) when a hot plasma is confined in a mirror geometry. It is the purpose of this note to point out that most of Ioffe's measurements fall into a very regular pattern and can be qualitatively explained by the assumption of a single monotonic relation between the unknown loss rate and the average ion energy. A discussion of some possible origins of the addition loss rate is given.

Dependence of Core Power Density on Reactor Parameters in a Gas-Cooled Reactor

Description: The influences of various key parameters on the reactor average core power density of gas cooled reactors are not easily seen from inspection of general analytic equations because of the interdependence of many key variables. A method is presented by which the analytical expression is reduced to a simple, approximate relation expressing the core power density as a function of independent key parameters of limited range.

Protection of Space Vehicles From Meteorite Penetration

Description: Thin bumpers have been proposed as a means of protecting a space vehicle from penetration by meteorites. Equations for the determination of the bumper thickness, the minimum spacing from the vehicle, the bumper temperature and the effect of the bumper on the thermal performance of a space radiator have been developed as functions of the duration of space flight, the surface area, temperature and wall thickness of the vehicle, and the physical properties of the bumper and vehicle wall materials.… more

Thorium Breeder Reactor Study: Optimization of a Blanket Processing Cycle To Obtain Minimum Total Inventory in a Chemical Reprocessing Cycle

Description: A reactor which produces U233 from Th232 needs to operate with as low total inventory of fissionable and potential fissionable material, U233 and Pa233, as possible in order to achieve short doubling times. The blanket processing cycle can be optimized to give minimum total inventory by the proper arrangement of Pa233 decay and U233 extraction steps. The optimization consists in choosing the proper storage time associated with each processing step. Graphs are presented correlating the optimized… more

Evaluation of Activated Charcoal Fission Gas Adsorbers Designed for the GC-ORR Loop Experiment No. 1

Description: The activated charcoal traps designed for the Gas-Cooled Oak Ridge Research Reactor Loop Experiment No. 1 are evaluated for room temperature operation involving the decontamination and atmospheric disposal of helium coolant gas contaminated by experiment failure. The maximum quantity of fission products expected to be released was calculated and the resulting hazard was examined on the basis of probable radiation doses to laboratory personnel resulting from exposure to the gas cloud.

Proposed Modifications to HRE-2 Core

Description: As a result of flow tests of a full-scale HRT flow model, it is proposed to modify the core flow by removing 5 or more screens, plugging the hole and reversing the direction of flow. This will provide better cooling and mechanical scrubbing of the core wall. A procedure for flushing solids out of the core was developed.

Results of Differential Bed Study of the Kinetics of the Absorption of UF6 on Sodium Fluoride

Description: One step in the Volatility process for power reactor fuel reprocessing involves the absorption and subsequent desorption of UF6 from NaF pellets in fixed beds. In 1958 an experimental study of the kinetics of absorption of HF on NaF beds was made. The purpose of this work was to extend the study to the kinetics of UF6 absorption on NaF. The results should be useful in the design and operation of the Volatility process.

Refinements of the Theory of the Infinitely-Long, Self-Acting, Gas-Lubricated Journal Bearing. Interim Report

Description: The lubrication equations for an arbitrary Newtonian fluid are derived directly from the general equations for conservation of mass, momentum, and energy. From the lubrication equations an inequality is obtained for the internal film temperature rise, after which the isothermal film equations are derived. Then, for perfectly-aligned self-acting journal bearings, a conservation equation is obtained. For gas bearings this condition gives: [formula] constant along the axis of the bearing. Applicat… more

The Influence of Point Defects on the Mechanical Properties of Lithium Fluoride : First Technical Report

Description: Lithium fluoride crystals were quenched into silicone oil from near the melting point. The return to an equilibrium structure during annealing was observed by means of mechanical tests and etching techniques. Crystals containing three levels of impurity, zone refined, commercially pure, and doped with 0.05 mole per cent magnesium, were used in order to separate the effects of foreign ions from those of thermal vacancies. The changes of mechanical properties produced by quenching and by subseque… more

Low Energy Nuclear Physics : Second Annual Report for the Period February 1, 1959 to January 31, 1960

Description: The general expression for the angular correlation between radiations produced in successive cascade transitions is derived by use of Racah algebra. The result is then specialized to the beta - gamma correlation and applied to two cases in which additional properties of the photon are specified, the circular polarization and the plane polarization. The prospect of testing time reversal and determining nuclear matrix element ratios by beta - gamma correlation measurements is explored using the n… more
