The drag characteristics of several airships determined by deceleration tests (open access)

The drag characteristics of several airships determined by deceleration tests

This report presents the results of deceleration tests conducted for the purpose of determining the drag characteristics of six airships. The tests were made with airships of various shapes and sizes belonging to the Army, the Navy, and the Goodyear-Zeppelin Corporation. Drag coefficients for the following airships are shown: Army TC-6, TC-10, and TE-2; Navy Los Angeles and ZMC-2; Goodyear Puritan. The coefficients vary from about 0.045 for the small blunt airships to 0.023 for the relatively large slender Los Angeles. This variation may be due to a combination of effects, but the most important of these is probably the effect of length-diameter ratio.

A high-speed low-sensitivity calorimeter for high activity (Ad Interim Report) (open access)

A high-speed low-sensitivity calorimeter for high activity (Ad Interim Report)

This document is a March 1949 Ad Interim Report on the development of a high-speed, low-sensitivity calorimeter at the Mound Laboratory. This calorimeter is a zero-compensating, thermocouple, twin type. The outside diameter of the aluminum tubing was machined for a slip fit into the glass test tube. Prior to assembling in the test tube, an aluminum plug was pressed in it midway from the ends. A groove was also milled on the outside down to the plug, and a copper-constantan thermocouple was secured in the groove after assembly. A single layer of aluminum foil was used to reduce radiation effects, and stray air currents were excluded with a cotton plug. The two arms of the calorimeter were placed in a three-liter beaker filled with water. The constantan leads of the two thermocouples were soldered together to make them compensating. The copper leads were connected to a L & N potentiometer, and a L & N galvanometer was also used. The potentiometer-galvanometer circuit was so connected that before each reading of the EMF of the thermocouples, the thermal EMF in the circuit could be accounted for. The galvanometer was then mounted on a heavy brass plate. The data show that when …

Radioactive contamination in the environs of the Hanford Works for the period October, November, December 1949 (open access)

Radioactive contamination in the environs of the Hanford Works for the period October, November, December 1949

This report summarizes the measurements made for radioactive contamination in the environs of the Hanford Works. The principal sources of the radioactivity originating as a result of operations at Hanford which affect the environment in this area are the two waste stacks in the separations area and the cooling water from the four pile areas. Measurements are also made on samples taken from the Hanford waste systems which are primarily confined within the project proper. Although monthly summaries of these data are reported in Health Instrument Divisions Environs reports, a somewhat more detailed discussion of these data is covered in the quarterly report. In this manner, a better evaluation of possible trends can be detected as a result of the increased number of measurements made available by combining the data for a three month period. The following areas are discussed: meteorology, radioactive contamination of vegetation, airborne contamination and air radiation levels, radioactive contamination in Hanford wastes, radioactive contamination in the Columbia and Yakima rivers; beta activity in rain and snow, and radioactive contamination in drinking water and test wells.

Some properties of beryllium oxide and beryllium oxide - columbium ceramals

High-temperature tensile and thermal-shock investigations were conducted on beryllium oxide and beryllium oxide plus columbium metal additions. X-ray diffraction and metallographic results are given. The tensile strength of 6150 pounds per square inch for beryllium oxide at 1800 degrees F compared favorably with the zirconia bodies previously tested. Additions of 2, 5, 8, 10, 12, and 15 percent by weight of columbium metal failed to improve the shock resistance over that of pure beryllium oxide.

A brief review of major problems at Redox (open access)

A brief review of major problems at Redox

During the last few months the Redox plant has been plagued with an excessive number of problems which have resulted in its inability to meet forecasted production schedules in November 1953, January and February 1954. The following paragraphs are intended to indicate some of the problems faced at Redox and the steps that are being taken to remedy them. It should be emphasized that the plant has been operating far above original design capacity and this fact tends to aggravate some of the problems. For example, although steps have been taken to increase the throughput capacity of certain of the head-end steps and some of the columns, it is most possible to install a second centrifuge, oxidizer or D-12 waste evaporator in parallel so that when any of these -- one of a kind -- pieces of equipment is out of service the entire plant is unable to operate.

The Fabrication of Stainless Steel-Uranium Dioxide Fuel Elements (open access)

The Fabrication of Stainless Steel-Uranium Dioxide Fuel Elements

Abstract: "Stainless steel-clad fuel sheet 0.020 in. thick with a 0.008-in. core of stainless steel plus UO2 was produced by roll cladding a powder metal compact. The effects of processing variables, core-matrix composition, quantity of oxide, and oxide particle size on the properties of the sheet were investigated. The strength and ductility of the core decreased sharply as the quantity of oxide in the core increased from 20 to 40 w/o. Over the range of matrix compositions investigated the particle size of the oxide had little affect on the core strength. In cores containing 21 w/o of oxide. 18 w/o chromium, 82 w/o iron matrix prepared from the elemental metal powders had the highest strength and ductility, but this matrix was susceptible to cracking during thermal cycling. As elemental 18 w/o chromium, 9 w/o nickel, 73 w/o iron matrix was the most satisfactory from the standpoint of fabrication and over-all characteristics of the resulting sheet."

Investigation of Redox D-12 Waste Concentrator No. 2 Coil Nest Failure (open access)

Investigation of Redox D-12 Waste Concentrator No. 2 Coil Nest Failure

Four D-12 coil nests have failed since the start-up of the Redox Separations plant. Due to the high contamination and radiation levels of these vessels, the cost of decontamination has prevented the examination of all but one of the four. It was hoped that the examination of D-12 pot #2 would lead to an explanation of all four failures. This report will deal primarily with the metallurgical examination of the failure of D-12 pot #2.

Chemical Stability of Purex and Uranium Recovery Process Solvent (open access)

Chemical Stability of Purex and Uranium Recovery Process Solvent

The desirability of operating many of the Purex columns at elevated temperatures, ca. 50-70 C, has made it necessary to obtain data on the stability of the solvent at these higher temperatures. Since the present diluent, Shell Spray Base, will not be entirely safe at the upper temperature limit, a number of diluents with higher flash point have been investigated concurrently with Shell Spray Base. This report presents data covering the first phases of this investigation, namely, the effect of nitric and nitrous acid on the solvent at 71 C. or higher temperatures.
