Abstract: In the present study, the variation of moderator composition was postulated to be effected by the inclusion of varying amounts of beryllium oxide in the graphite of an SGR.

The ability of the atmosphere to disperse and diffuse smoke and gases varies widely with weather conditions. The rate of diffusion is governed mainly by the degree of atmospheric turbulence present. The latter is in itself an extremely complex air motion which acts as the mixing agent in diffusion. This turbulence, which is so fundamental in the diffusion process, depends on such quantities as wind speed, rate of change of wind speed or wind direction with height, and rate of change of air temperature with height. Since these conditions differ widely from hour to hour and day to day, there is a corresponding variation in the diffusing capacity of the atmosphere. The rate of change of temperature with height and the wind speed have the most pronounced effect on the physical appearance of smoke plumes, which in itself provides a clue to the diffusing power of the atmosphere during various atmospheric conditions. The purpose of this note is to present, in semi-technical terms, some of the basic physical concepts related to the behavior of gaseous stack effluents after release into the atmosphere, and to describe certain visible geometrical features of effluent plumes that are directly related to the physical state …

This is the monthly report for the Hanford Laboratories Operation. Metallurgy, reactor fuels, physics and instrumentation, reactor technology, chemistry, separation processes, biology, financial activities, employee relations, laboratories auxiliaries, radiation protection, operation research, inventions, visits, and personnel status are discussed. This report is for November 1958.

Introduction: The description of the Organic Moderated Reactor Experiment, (OMRE), its location, its safety system, and operative procedures have been previously detailed. The present report, although dealing with the subject of OMRE safety, has the more detailed intent of (1) determining the behavior of the OMRE under extremely unlikely sets of conditions; and (2) providing additional design information in the areas of reactivity coefficients, burnout heat flux, and reactor control.

"General Chemistry investigations reported herein includes: (1) the Organic Coolant-Moderator Program, (2) investigations on zirconium hydride, and (3) analytical chemistry."

A large number of experiments relating to nuclear structure and materialization of energy will fall within the energy range of primary and secondary particles available from the Bevatron. Some experiments of interest are outlined below with pertinent comments. Proton-proton scattering can be extended to the high energy range using liquid hydrogen targets and hydrogenous materials by bombarding the target with the internal beam or using externally scattered protons. Proton-deuteron scattering measurements using liquid deuterium targets or solid materials can also be extended. Proton scattering from heavier nuclei may be found less difficult to interpret at these level energies as the nucleons will interact more or less independently. The wavelength of the bombarding particles will now be much smaller than nucleon diameters. Nuclear collisions represent by far the most important interaction between high energy nucleons and matter. Proton-neutron charge exchange interaction within the internal target will provide an external flux of neutrons which can be used directly for total nuclear cross section measurements and neutron-proton scattering. Low energy measurements, say below 200 Mev; show that nuclear interaction cross sections do not go down as 1/{lambda} as reactions become predominantly nuclear rather than electromagnetic. Measurements can now be extended into the Bev …

The techniques used in sampling, analyzing, and evaluating results for determining hazards from external radiation, airborne radioactive material, radioactive contaminants in mill effluents, and urinary uranium, as applied to the Monticello, Utah, uranium mill, are described. Corrective measures used by National Lead Company, Inc., at the Monticello Mill are described along with the results from later surveys which showed large reductions in the potential radiation hazards. Details are given of the methods used to determine personnel exposures to radioactive and silicosis-producing dusts, potential external radiation hazards and in assaying mill effluents for uranium and radium, assaying urine samples for uranium, as well as the standard operating procedures issued at Monticello to employees for preventing and/or controlling personnel exposures.

Two designs of sodium cold traps for the HNPF have been subjected to full scale tests, Performance features that were investigated include oxide removal efficiency, oxide capacity, pressure drop characteristics, economizer effectiveness, and temperature profiles, Results indicate that both designs should perform satisfactorily in the Hallam plant, (auth)

Boillng points, freezing points, and densities were measured in the concentration range between uranyl nitrate hexahydrate and uranyl nitrate dihydrate. The surface tension of molten uranyl nitrate hexahydrate was determined to be approximately 45 dynes per square centimeter at 90 to 1OO icient laborato C. (auth)

Report presenting an investigation on canopy pressures and canopy-fuselage forces and moments under conditions of combined pitch and sideslip. The canopy configurations tested varied in windshield shape (flat, vee, and round) and were tested at two Mach numbers and Reynolds numbers.

Report presenting zero-lift drag results for two 60 degree delta-wing configurations with air inlets. One had twin conical-shock semi-circular scoops just ahead of the wing-body juncture and one had a modified wing section over the inboard portion to allow installation of modified triangular inlets in the wing leading edge. Results regarding the drag coefficients and mass-flow ratios are provided.

Report presenting an investigation of a configuration with a body of fineness ratio 16.9, a 52.5 degree sweptback wing of aspect ratio 3, taper ratio 0.2, and NACA 65A004 airfoil section, and an incline tail which was aeropulsed continuously in pitching during free flight with and without a sustainer rocket motor operating. The Mach number range covered was from 1.4 to 2.3. Results regarding drag, total normal force and pitching moment, wing normal-force-curve slope, flow conditions at the horizontal tail, and cross coupling are provided.

Report discussing testing of a multijet 60 degree delta-wing airplane configuration with twin-engine exhausts at specified locations under the wing. Data was obtained for jet-on and jet-off conditions between a range of Mach numbers. Results are presented for the effect of jet on drag, jet effect on lift, static longitudinal stability, and dynamic longitudinal stability.

Memorandum presenting an experimental investigation of a two-dimensional, 6.6-percent-thick, 6-foot-chord airfoil section equipped with suction slots for laminar-boundary-layer control. The section was designed to have favorable pressure gradients between the suction slots. The laminar boundary layer on the airfoil had the same extreme sensitivity to minute details of the model surface condition as has been found in other investigations.
