Paper presenting three ideas regarding potential simplifications of missile-control systems in order to make them more reliable without sacrificing system performance. The three methods presented include an autorotating-vane spoiler, a bellows flap, and free controls. All are based on modified airplane control systems.

From abstract: These results demonstrate that the self-potential method is not satisfactory for locating and delineating sulfide-bearing uranium ore bodies under conditions similar to those in the Happy Jack area.

From abstract: The purpose of the survey was twofold: to determine the trend of the Hideout Channel across Deer Flat and to delineate fractures cutting through the ore deposit at the Hideout mine.

This report follows the study of the properties of eutectic uranium-chromium alloy which is of interest in the Dow-Detroit Edison power reactor. The reactor is described in this report, as well as the casting of alloy, shrinkage measurements during solidification, density measurements, microstructures and macrostructures, mechanical properties, and specific heat data.

Survey of properties of materials which might be suitable for use in various locations in a supercritical-water reactor. Properties examined include tensile strength, rupture strength, endurance strength, Young's modulus, tensile elongation, coefficient of thermal expansion, coefficient of thermal conductivity, density, nominal composition, usual heat treatments and thermal-neutron-absorption cross sections.

Five telescope actuator systems designated as ``R``, ``P``, ``L``, ``K`` and ``C`` were fabricated at New York Ship. All five were similar in specifications except for minor detail. For overall assembly refer to du Pont arrangement drawings W-153422, W-153423, and W-153424. These drawings illustrate ``R`` unit; however, they are representative of all units. They show a complete listing of material required and an overall view of the telescoping assembly. Since jigs and special tooling were set up to conform to a definite deck plate fabrication sequence, the inspection procedures and methods described in this book will follow logically the fabrication steps.

This report addresses the atomic energy commission division of reactor development information meeting.

Data on thorium are compiled and the use of thorium as a fuel material is discussed. It was assumed that the general reactor configuration will follow the conventional SGR-SRE reactor design of a graphite-moderated sodium-cooled metallic fuel system. Factors outlined which affect the use of thorium as a fuel material are availability of ore, capacity of processing plants, purity specifications, design and use of materials in fuel elements which may affect chemical separation economics, and technical feasibility. General metallurgical properties of thorium are described including melting point, density, chemical purity, thermal conductivity, thermal expansion, phase transformations, corrosion in liquid metals, tensile and creep strength, dimensional stability, and alloying properties. Methods of chemical processing, fabrication, and cladding are outlined. The advantages and disadvantages in the use of thorium as a fuel are summarized. (M.C.G.)

There are two different types of investigation of interest in high energy nuclear phenomena. One can observe gross effects such as the production of large numbers of heavy particles of different types, or one can study the elementary particles themselves which result from these collisions, for example, the kappa mesons, to determine modes of decay and the energy spectra of the resulting particles. This discussion will deal with the gross aspects of high energy interactions and will review the work of Fermi: High Energy Nuclear Interactions, Progress in Theoretical Physics, 5, No. 4, July-August, 1950.

The relative probabilities for alternate processes initiated by a nucleon-nucleon collision depend on the dynamics involved and on the volume in phase space accessible to each final state. According to Fermi this last aspect alone may be of decisive importance. Such an assignment would follow were an approximate statistical equilibrium reached. The volume occupied by the incident nucleons and the associated pion clouds will have very large energy density at the instant of collision. Knowing that the interactions of the pion fields are strong, Fermi assumes that this energy is suddenly distributed among the various degrees of freedom present in the interaction volume in accord with statistical laws. He then computes the statistical probability that a certain number of pions will be created with a given energy distribution. It is then assumed that the energy will rapidly dissolve and that the particles into which the energy has been converted will fly out in all directions. Fermi argues that this approach may give a fairly good approximation to the actual case; since the number of possible states of the given energy is large and the probability of establishing a state to its average statistical weight will be increased by the number …

This discussion will review the results of a survey of present plans for the Bevatron counting equipment. Proposed counting facilities, tentative specifications for desired counting equipment, a view of past counting techniques, and some of the later associated circuits will be considered.
