A High Volume Casting Furnace for Plutonium

Description: A high-vacuum casting furnace with an internal diameter of 15 inches has been designed, fabricated, and installed at LASL. The furnace was designed to accommodate casting crucibles up to 7 inches OD; however with a larger diameter heating element, casting crucibles up to 9 inches could be accommodated. This report describes the basic features of the furnace and presents engineering drawings of both the furnace and the furnace box.

Scintillation Counter [gamma]-Spectra Unfolding Code for the IBM-650 Computer

Description: Abstract. An IBM-650 computer code for the detailed unfolding of [gamma]-ray spectra obtained from NaI scintillation counters has been developed. The procedure is set up to remove analyzer scale dependence and to largely remove energy dependences. Computer time is about 1 minute per [gamma]-ray.

Mechanical design and environmental testing of a computing gamma spectrometer. [Portable spectrometer for identifying radioactive materials]

Description: A portable computing gamma spectrometer has been constructed and environmentally tested. It functions properly after undergoing both a 150-mm drop test and a 1.5-g vibratory sweep test at 263/sup 0/K. The drop height represents the level beyond which at least partial failure results. The unit is unaffected by thermal cycling but is somewhat sensitive to thermal shock. It is mounted in a waterproof container.

Enhancement of Strength and Ductility in Bulk Nanocrystalline Metals

Description: The purpose of this project is to develop a robust scientific and technological framework for the design of high-strength and -ductility nanocrystalline materials for applications of technical importance to the Laboratory. The project couples theory and experiments with an emphasis on materials of macroscopic dimensions (mm to cm) that are composed of nanoscale (<100 nm) grains. There are four major tasks: (1) synthesize nanocrystalline materials with grain size in the 5- to 100-nm range; (2… more

Measurement of Shear Strength in BCC Materials Subjected to Moderate Pressures

Description: An experimental procedure is reported to perform shear tests on specimens held under moderately high hydrostatic pressures (on the order of 10 GPa). The mechanical behavior of materials subjected to such pressures, varies substantially from that observed at atmospheric pressure or even pressures typically attained during industrial processing. These differences must be incorporated into models such as the Steinberg-Guinan hardening model or discrete dislocation dynamics simulations. The goal of… more

Electromagnetic Imaging of CO2 Sequestration at an Enhanced-Oil-Recovery Site

Description: The two year LDRD-ER-089 project Electromagnetic Imaging of CO{sub 2} Sequestration at an Enhanced-Oil-Recovery Site used a dual track approach to imaging and interpreting the effectiveness and migration of CO2 injection at an enhanced oil recovery site. Both field data and laboratory data were used together to aid in the interpretation and understanding of CO{sub 2} flow in a heavily fracture enhanced oil recovery site. In particular, project highlights include; {lg_bullet} The development of … more

LDRD Final Report 01-ERI-001 Probing the Properties of Cells and Cell Surfaces with the Atomic Force Microscope

Description: We have developed new techniques based on atomic force microscopy (AFM) to image, and to quantify the strength of, specific receptor sites on the membrane of a living cell. AFM has developed rapidly during the past decade, providing nanometer scale resolution in the imaging of biological materials ranging in size from single molecules to intact cells. By monitoring the cantilever deflection during approach-retraction cycles (i.e. force-volume curves), the unbinding forces have been determined f… more

Advanced, soluble hydroliquefaction and hydrotreating catalysts. Final report, April 2, 1990--August 31, 1993

Description: The purpose of the present program is to develop soluble analogs of surface confined catalysts that can be impregnated directly into the coal structure at low temperatures. This approach should avoid problems related to surface area dependence, a two phase (surface-liquid) reaction system and, mass transport limitations. Heteropolyanions (HPAs) offer the opportunity to develop soluble forms of surface confined catalysts. HPAS, are inexpensive, well-characterized, water soluble metal oxide clust… more

WRAP low level waste (LLW) glovebox acceptance test report

Description: In June 28, 1997, the Low Level Waste (LLW) glovebox was tested using glovebox acceptance test procedure 13031A-85. The primary focus of the glovebox acceptance test was to examine control system interlocks, display menus, alarms, and operator messages. Limited mechanical testing involving the drum ports, hoists, drum lifter, compacted drum lifter, drum tipper, transfer car, conveyors, lidder/delidder device and the supercompactor were also conducted. As of November 24, 1997, 2 of the 131 test … more

Drilling with fiber-transmitted, visible lasers

Description: High power and radiance copper-vapor laser technology developed at Lawrence Livermore National Laboratory shows great promise for many materials processing tasks. The authors recently transmitted the visible light produced by these lasers through fiber optics to perform hole drilling experiments. They found the tolerances on the hole circulatory and cylindricity to be excellent when compared to that produced by conventional optics. This technique lends itself to many applications that are diffi… more

New K Reactor aluminum HCR: Temperature study

Description: Recent (HCR) Horizonal Control Rod operating problems at the K Reactors, caused primarily by graphite stack distortion, have stimulated several designs of HCR`s capable of operating under adverse conditions. One such design is an aluminum HCR, not completely dissimilar to the present HCR`s, conceived by the Research and Engineering Operation of I.P.D. The successful use of aluminum as a structural material is strongly dependent upon the operating temperature of the aluminum. This study was cond… more
