The conceptual design of a nuclear ram jet-rocket missile is preserved. This missile is a modified, scaled-up AC-210 nuclear ram jet carrying ammonia in the space enclosed by the spike and inlet diffuser. The payload may be a 10,000 pound thermonuclear weapon or equivalent weight of reconnaissance equipment plus local shielding as in the AC-210 missile. The payload for a missile of body size equivalent to the AC-210 will be reduced by the weight of ammonia.

From introduction: The Cordilleran Foreland (King. 1951, p. 58-62; Horberg and others, 1949, p. 192194) forms a broad north-south belt, parallel to and east of the Cordilleran geanticline (fig. 1), in which the predominant geologic structure is a series of anticlinal mountains and broad asymmetric basins that contrast sharply with the folds and overthrusts related to the Cordilleran geanticline. A tectonic map of most of the Cordilleran Foreland (fig. 2) is being compiled as an aid to study the geologic setting of uranium deposits within the region, and to determine what relationships may exist between the distribution of uranium deposits and the regional tectonic pattern (Osterwald, 1955). The map will show the distribution of faults, uranium deposits, areas of volcanic activity, and crestlines and troughs of folds.

From introduction: The Cordilleran Foreland has been defined by Osterwald (1956, p. 1) as "a region containing distinctive structural elements that forms a broad north-south belt parallel to and east of the Cordilleran geanticline...." The location of these tectonic regions is shown in figure 4 of this report. region are an important potential source of uranium in the United States. The accompanying maps (figs. 1, 2, and 3) show the location of most of the known uranium deposits and the localities from which samples, containing 0.01 or more percent uranium, or uranium minerals, have been obtained. The outcrop patterns of the principal ore-bearing formations are from the sources indexed on each map.

This report follows investigations of methods for sealing the ends of stainless steel-uranium oxide fuel pins with the objective to develop an end-capping method that would give consistently good-quality closures in production.

Report discussing studies regarding properties of the zirconium-uranium epsilon phase related to stability and existence range. Data showing this phase's thermodynamic stability is presented as well as the zirconium-uranium constitutional diagram. Oxygen and nitrogen effects on zirconium-uranium alloys and epsilon-phase alloys is included as well as ternary zirconium-uranium-oxygen diagrams.

Thesis discussing the relative yield of neutral pions from elements in a reaction "as a function of the quantum-limit energy (the maximum energy of the quanta in the bremsstrahlung beam) of the Berkeley synchrotron." Interpretation of the results leads to values for the mean free path for absorption of the neutral pions in nuclear matter.

Abstract: "The elastic double scattering of deuterons by complex nuclei has been investigated experimentally. Measurements were made on carbon, aluminum, and copper at around 157 Mev; on lithium, beryllium, and carbon at around 125 Mev; and on carbon and aluminum at 94 Mev. The expected tensor components of the deuteron polarization have not been observed. Measurements have been made of the differential cross section and vector-type polarization as a function of angle for the scattering of deuterons from the above elements, at the above energies. The observed polarizations were larger than would be expected on the basis of the individual nucleon-nucleus interactions. In a second experiment we measured the 169-Mev proton-proton polarization at 10, 15, 22.5, 30, and 35 in the laboratory system. The results indicate that partial waves up to and including L = 3 are important at this energy."

This report presents the best estimate possible on the basis of the available information as to how high an energy would be necessary in order that the gas pressure which could be tolerated would be attainable with present techniques (say 10-(-7) mm Hg.)

Abstract: "The measurement of large, high-frequency, short-pulse currents--ordinarily complicated by inductance, stray magnetic fields, and magnetic forces that tend to disassemble the measuring device--is simplified and made with an average error of 2-1/2% by the use of a specially developed noninductive radial shunt in conjuntion with an oscilloscope. The skin-effect correction is derived theoretically and the accuracy of the method is demonstrated."

Abstract: "The neutrons from the linear pinch in Berkeley have been shown to originate from deuteron collisions with a large net center-of-mass velocity in one direction along the axis of the pinch tube. The interpretation of this result is that the neutron production associated with the pinch is non-thermonuclear in origin. The object of this paper is to review the experimental evidence and discuss a possible source of the neutron production."

This document presents a summary of work and progress at the Hanford Engineer Works for April 1956. The report is divided into sections by department. A plant wide general summary is included at the beginning of the report, after which the departmental summaries begin. The Manufacturing Department reports plant statistics, and summaries for the Metal Preparation, Reactor and Separation sections. The Engineering Department`s section summaries work for the technical, design and project sections. Costs for the various departments are presented in the financial department`s summary. The Medical, Radiological Sciences, Utilities and General Services, Employee and Public Relations, and Community Real Estate and Service departments have sections presenting their monthly statistics, work, progress, and summaries.

In a previous study it was determined experimentally that heat deterioration, or burnout, of the shield masonite is more severe than radiation damage under existing and proposed operating conditions. Higher shield temperatures, which are expected to result from increased power levels, fringe enrichment, and higher graphite temperatures, will markedly increase the rate at which the masonite burns out. The laminated iron-masonite biological shield will lose, as a result of burnout, the hydrogen and oxygen necessary to attenuate and moderate neutrons. The purpose of this production test has been to obtain experimental data from which future shield leakage rates could be estimated. The attenuation data reported here were obtained in the DR pile bulk shield facility from experiments using various void spacings to simulate burnout conditions. From these data it was hoped to determine (1) the resultant attenuation properties of the shields, and (2) the exposure rates due to radiation penetrating the shield.

Slug ruptures characterized by intergranular corrosion failure of the aluminum can (Hot Spot Ruptures) have been a major cause for loss of reactor production, particularly during the past year. Although the cause for these failures is not definitely known, it is suspected that fuel elements when cocked in the process tube will sufficiently distort the neutron flux and the heat transfer characteristics in a localized area that very high local temperatures will exist and the corrosion rate of the aluminum can in these areas will be accelerated. It is the purpose of this test to introduce slugs that are known to be cocked and compare their resistance to rupture with slugs that are known to be uncocked when initially charged.
