  • Sulfur hexafluoride (SF/sub 6/) gas is being reclaimed and reused utilizing three modified commercial SF/sub 6/ gas reclaimers. Applications are discussed, as well as problems encountered during operation of these units. Estimates of cost savings to Department 4250, when using the reclaimers, are also discussed.
  • Supercomputing `94, a high-performance computing and communications conference, was held November 14th through 18th, 1994 in Washington DC. For the past four years, Sandia National Laboratories has used this conference to showcase and focus its communications and networking endeavors. At the 1994 conference, Sandia built a Switched Multimegabit Data Service (SMDS) network running at 44.736 megabits per second linking its private SMDS network between its facilities in Albuquerque, New Mexico and Livermore, California to the convention center in Washington, D.C. For the show, the network was also extended from Sandia, New Mexico to Los Alamos National Laboratory and from Sandia,more » California to Lawrence Livermore National Laboratory. This paper documents and describes this network and how it was used at the conference.« less
  • This report provides summary descriptions of Energetic Materials (EM) Research and Development activities performed at Sandia National Laboratories and funded through the Department of Energy DP-10 Program Office in FY97 and FY98. The work falls under three major focus areas: EM Chemistry, EM Characterization, and EM Phenomenological Model Development. The research supports the Sandia component mission and also Sandia's overall role as safety steward for the DOE Nuclear Weapons Complex.
  • Smectite, 90 to 100% interstratified illite-smectite, chlorate, and kaolinite are identified in boreholes drilled in fluvial and alluvial fan deposits of the Plio-Pleistocene Livermore Formation in the vicinity of Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratories (SNL), Livermore. X-ray diffraction, scanning electron microscopy, and electron microprobe studies indicate the clays persist through 150 ft of gravels, sands, silts, and mudstones of the vadose zone to total drilling depths of 200 ft in the saturated zone. Scanning electron microscopy indicates that true clays (layer silicate only) comprise between 2 and 15 modal percent of the Livermore Formation. Authigenic andmore » detrital smectite, 90% interlayered illite-smectite, and chlorate persist throughout the stratigraphic section; kaolinite occurs only in the upper 100 ft of the section and is absent below. Smectite comprises between 60 to 90% of the true (layer silicate only) clay fraction. Illite and kaolinite[plus minus]chlorite abundances fluctuate between 10 to 30% and 10 to 20% of this fraction, respectively. Authigenic smectite, illite, and chlorate crystallize together with detrital phases; the authigenic component increases with depth. The relative percentages of clay minerals define unique mineralogical intervals, which can be correlated between boreholes. Pervasive microfractures and interconnected porosity are inherent in the finer sediments; the microfractures typically are 1 mm or less in width and are variably spaced. Voids and microfractures are conspicuously lined by clays. Porosity for the argillaceous sediments ranges between 23 and 40%; Brunauer, Emmett, and Teller (BET) specific surface area decreases variably from 40 m[sup 2]/g near the surface to 15 m[sup 2]/g at the 115-ft depth. Within the pelitic matrix, iron, iron-titanium, chromium, and manganese oxides are pervasive.« less
  • The US Department of Energy is planning to acquire land adjacent to or in the immediate vicinity of the research center complex represented by Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratories, Livermore (SNLL). The land acquisition will be used to create a buffer zone to enhance the physical security of the site. The purpose of this environmental assessment is to describe the activities associated with the land acquisition phase of the Enhanced Site Security Project and to evaluate potential environmental disruptions. The project site is located in a rural area of southeastern Alameda County, California, where the primarymore » land use is agriculture; however, the County and/or the City of Livermore has zoned much of the project area for industrial development. The environmental impacts of the land acquisition phase of the project include only socioeconomic effects, basically stemming from the prevention of industrial development in the desired buffer zone; later project phases (construction of security facilities, landscaping, etc.) may include surface disturbance, high noise levels, possible increases in site erosion, and decreased air quality. These impacts would be temporary and could be mitigated in part by standard precautionary measures. 32 references, 12 figures, 1 table.« less
