The Injection Casting of Plutonium

Description: Plutonium metal can be injected into cold metal molds to form castings with thin walls. The operation is performed in a vacuum chamber, using an inert gas as the injecting medium. Sound pieces free of gas cavities can be made using either pure or delta-stabilized plutonium. This report describes the equipment and techniques used to cast a typical thin section piece in the form of a 6 in. diameter, 45' cone.

Pressure Balance in a Toroidal Pinch

Description: Abstract: In the study of a linear pinch, use of the equation of pressure balance has proven to be a powerful method of analyzing data taken with a magnetic probe. The toroidal pinch, however, is a geometrically more complicated object, and the use of the pressure balance equations is not so clean cut. It is the object of this note to analyze the pressure balance equations for a torus to the point where they might prove useful in interpreting probe data.

Nuclear Propulsion Test Reactor Kiwi-A Neutronic Studies

Description: Critical conditions were obtained for a series of uranium-graphite fueled assemblies in the C/Oy range 150 to 500 with thick graphite reflectors and Be or D2O islands. Perturbations were studied in order to find the effect on reactivity of geometrical changes and engineering features. Information from these studies was used to develop a mock-up of an optimum reactor geometry for the first rocket reactor test device, Kiwi-A. Studies on a zero power mock-up (Zepo-A) helped establish its design de… more

Preliminary Investigation of a Five-Crystal Scintillation Gamma-Ray Spectrometer

Description: Abstract: A five-crystal scintillation gamma-ray spectrometer was constructed for use as a Compton coincidence spectrometer or as a pair coincidence spectrometer. Preliminary tests are discussed. The efficiency in either mode of operation was found to be low; however, the backgrounds were favorable and good definition of characteristic lines was achieved...Future tests and plans for improvements are discussed."

Some Reactor Physics in the Rover Project

Description: From abstract: "A general and systematic development of reactor computing methods and detailed application given in Report LAMS-2255 separately is supplemented in this report for a few specific systems of interest to the Rover program. Neutron cross sections, reactor description, and computed results are given for a reactor required to have a constant (radially) power distribution at high temperatures."

The Rolling of Gold Sheet for LAPRE 2 Pressure Liner

Description: From abstract: "This report discusses a special handling procedure devised to prevent contamination of high-purity gold while processing the metal from cast billet to final sheet. Gold of 99.99% purity was cast into rectangular billets and rolled into sheet whose final dimensions were 48 by 12-1/2 by 0.015 inch...As a final step, the sheet was annealed dead-soft in preparation for subsequent forming operations."

An Integral Experiment to Measure the Tritium Production From Li7 By 14 Mev Neutrons in a Lithium Deuteride Sphere

Description: A sphere of LiD 2 feet in diameter was irradiated by 2 x 10<sup>15 14 Mev neutrons. Samples of Li<sup>7 metal were positioned at various radii for the irradiation. An analysis of these samples for tritium led to a determination of the number of tritons produced by 14 Mev neutrons acting on Li<sup>7 in a LiD system.

A Measurement of the [Lithium-7] Cross-Section for Several Neutron Energies From 4 to 15 Mev by Absolute Counting Techniques

Description: A measurement of the [Lithium-7] reaction cross section by absolute counting of the tritium betas is described. The cross section was measured at several neutron energies between 4 Mev and 15 Mev. A comparison with results by emulsion techniques is given.

On the Possibility of Extracting Energy from Gravitational Systems by Navigating Space Vehicles

Description: This report describes a number of problems, generally involving the possibility of using reserved kinetic energy in such a way as to acquire, by suitable near collisions with one or the other of the celestial bodies discussed, much more kinetic energy that it possesses -- more by an order of magnitude than the available reserve energy would allow it to acquire by itself.

Stability of a Linear Pinch With a Thick Boundary

Description: The stability of a linear pinch is investigated by means of the "6W" formalism of E. A. Frieman. It turns out that when attention is confined to the surface layers of the plasma, convenient stability criteria can be deduced for very general cylindrically symmetric distributions of magnetic field and plasma.

A Proposal For Reducing Impurities in a Stabilized Pinched Discharge

Description: It is proposed to reduce the initial wall hangup and consequent plasma contamination of a stabilized pinched discharge by reducing the Bz pressure difference across the current sheath to nearly zero at early times. Two methods for accomplishing this are proposed, both involving multistage programming of the Bz system.

Fast Neutron Cross Sections: Corrections to LA-1714 and a Correlation of 3 Mev Values

Description: Recent measurements on the long counter efficiency in which comparisons were made with the (n, p) scattering cross section, additional variations in efficiency were found which varied slowly with neutron energy but were still correlated with the total neutron cross section of carbon. Because of these variations in efficiency there are errors in the fission cross sections reported in LA-1714. Corrections to these data have been given here.

Radioactive Decontamination Tests on Surgeon's Gloves Contaminated With Plutonium

Description: Report discussing the effectiveness of various methods for removing plutonium from contaminated gloves. The cost of decontaminating the gloves using the most effective method was three times the cost of new gloves, and "consumer resistance" was noted among users of treated gloves.

Description: The spatial and spectral distributions of the neutrons from 14-Mev neutron interactions with Ta, Bi, and U have been obtained using nuclear emulsion detectors in conjunction with a neutron collimator. The space-integrated neutron spectrum has been obtained for Be by means of a sphere experiment.

Magnetic Field Distributions in a Pinched Discharge

Description: By use of small magnetic probes inserted into the discharge, the magnetic field distributions in the interior of a high-power pinched discharge have been measured as a function of time. From these data the current distributions can be deduced. By applying a static pressure calculation, in the cases when the radical pinch accelerations are small, the plasma pressure nkT in the pinch has been determined, with superimposed axial magnetic fields, and for stable and unstable configurations.
