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.

Neutron Emission Probabilities From the Interaction of 14-Mev Neutrons With Be, Ta, Bi, and U238

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.

Preliminary Survey of Uranium Metal Exponential Columns

Description: Reflected cylindrical exponential columns of bare and natural uranium were constructed of stacked plates of oralloy (93.4%) and tuballoy. Average concentrations of U235 ranging from 0,72% to 9.18% were investigated. Flux distributions, buckling values, and spectral indices were obtained. The indicated U235 concentration for infinite critical mass is about 5.5%.

Preparation of Plutonium Sheet by Extrusion

Description: Plutonium sheet of uniform thickness and good surface can be made by the extrusion of a tube which is then split and flattened. This report describes the equipment and the operating conditions for making sheet 0.005 to 0.055 in. thick with areas up to 24 in. square.
