The acoustic emission from both powder and ingot source beryllium has been measured as a function of strain and prior heat treatment. Most measurements were made during tensile deformation, but a limited number of compression tests have also been performed. The acoustic emission observed was of the burst type, with little or no contribution from continuous type emission. The emission was characterized by the variation of burst rate and average energy per burst as a function of strain. The tensile behavior was qualitatively similar for all the materials tested. Burst rate maxima centered roughly at 0.1 percent and 1.0 percent plastic strain were observed. The magnitude but not the strain at the low strain burst rate peak was very sensitive to prior thermal treatment, while the higher strain burst rate peak was insensitive to prior heat treatment. An energy per burst maximum was observed at 0.2 percent plastic strain, the magnitude of which was moderately sensitive to heat treatment. The Kaiser effect is observed in the material studied. Emission during compression was similar to that observed in tension. The acoustic emission observed is attributed to dislocation motion, as proposed by James and Carpenter for LiF, NaCl, and Zn.

The technical status report covering the period April 24 through June 3, 1978 dealing with the study on potential for conserving energy by shifting some shipments of manufactured products from motor trucking to railroads is presented. The work activities for the period comprise eight subtasks, consisting of the identification of shippers relevent to the study, three rounds of interviews and analysis, preparation of interim and final reports, and discussions with railroads. Some transport data on 24 commodities are tabulated in an Appendix, Analysis of the Energy Savings Implications of Shifts in Shippers' Modal Choice from Truck to Rail Freight Services.

The size of magnetic moment jumps of a particle in a long, thin equilibrium magnetic mirror field is shown to be related to the complex zeroes of the mirror mode parameter B + 4..pi..dP/sub perpendicular//dB. A consequence is that adiabaticity places a lower limit on ..beta.. than does the mirror mode.

Scientists are finding increased applications for microcomputers as process controllers in their experiments. However, while microcomputers are small and inexpensive, they are difficult to program in machine or assembly language. A high-level language is needed to enable scientists to develop their own microcomputer programs for their experiments on location. Recognizing this need, LLL contracted to have such a language developed. This report describes the result--the LLL BASIC interpreter, which operates with LLL's 8080-based MCS-80 microcomputer system. 4 tables.

Thoria is irradiated in the Hanford reactors for the production of U-233. The product quality is acutely sensitive to the control of the unseparable contaminant isotopes U-232 and U-238. Recent discussions between personnel of ARCHO and DUN indicate that product quality of a forthcoming separations campaign can be significantly enhanced by analysis of data for which we solicit your support. This letter describes the necessary background and the required analysis. Virgin thoria lots are processed to required transient impurity levels by the National Lead Company of Ohio. They are subsequently shipped to DUN identified by this virgin lot number and are accompanied by the transient impurity levels and U-238 contaminant levels based on statistical samples and analytic chemistry results. Virgin NOL thoria lots consist of various tonnages or fractions thereof, and two or three such lots are typically combined into a single DUN thoria element lot. By weighted averages, the U-238 contaminant level of DUN thoria lots is thus accurately known. The range of U-238 contaminant in any given DUN lot was further controlled by establishing three categories, A, B, and C, with U-238 ranges of 0-1.99, 2.0-3.3, and 3.4-5.0, respectively, on a thoria basis. Thus when a DUN lot …

A continuous, cascade dissolver systems, using an air-lift pump for circulation and suspension of solid particles has been developed. This dissolver system has been used to dissolve plutonium oxide, incinerator ash and other residues generated during the chemical processing of plutonium. An integral part of the dissolver system development involved the design and fabrication of a reliable continuous feed system for the dissolver.
