Multielement analysis of geologic materials by inductively coupled plasma-atomic emission spectroscopy

Description: Atomic emission spectroscopy using an inductively coupled plasma (ICP) source permits the rapid acquisition of multielement geochemical data from a wide variety of geologic materials. Rocks or other solid samples are taken into solution with a four acid digestion procedure and introduced directly into the plasma; fluid samples are acidified or analyzed directly. The entire process is computer-controlled, fully-automated, and requires less than five minutes per sample for quantitative determinat… more

Pentamethylcyclopentadienyl and bis(trimethylsilyl)amido complexes of the di- and trivalent lanthanides

Description: The reaction of the divalent iodides YbI/sub 2/ and EuI/sub 2/ with NaN(SiMe/sub 3/)/sub 2/ has provided pentane-soluble, monomeric derivatives of the divalent lanthanides. These compounds are isolated as the solvated species Eu(N(SiMe/sub 3/)/sub 2/)/sub 2/L/sub 2/ (L = thf or 1,2-dme), Yb(N(SiMe/sub 3/)/sub 2/)/sub 2/(thf)/sub 1/ /sub 5/ and Yb(N(SiMe/sub 3/)/sub 2/)/sub 2/L/sub 2/ (L = 1,2-dme or OEt/sub 2/), or as the sodium salts NaM(N(SiMe/sub 3/)/sub 2/)/sub 3/ (M = Eu or Yb).

Development of BEACON technology. Quarterly report, April-June 1982

Description: The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Experiments were continued this quarter with the objective of improving the carbon deposition efficiency using a Paraho retort off-gas mixture. Analysis has shown that the use of the Paraho off-gas to make hydrogen would be att… more

Floristic composition and plant succession on near-surface radioactive-waste-disposal facilities in the Los Alamos National Laboratory

Description: Since 1946, low-level radioactive waste has been buried in shallow landfills within the confines of the Los Alamos National Laboratory. Five of these sites were studied for plant composition and successional patterns by reconnaissance and vegetation mapping. The data show a slow rate of recovery for all sites, regardless of age, in both the pinon-juniper and ponderosa pine communities. The sites are not comparable in succession or composition because of location and previous land use. The two o… more

One-dimensional code to predict the thermal behavior of the UTSI MHD radiant furnace

Description: An analytical model of the thermal behavior of the radiant furnace components installed in the CFFF has been developed. Efforts have been primarily directed towards obtaining a representative global evaluation of the heat recovery of the major downstream components. An overall review of the heat transfer code developed specifically for the DOE CFFF downstream components is presented. The basic methods by which the gas state, transport properties, and the thermal radiative and convective propert… more

(Environmental investigation of ground water contamination at Wright-Patterson Air Force Base, Ohio)

Description: An environmental investigation of ground water conditions has been undertaken at Wright-Patterson Air Force Base (WPAFB), Ohio to obtain data to assist in the evaluation of a potential removal action to prevent, to the extent practicable, migration of the contaminated ground water across Base boundaries. Field investigations were limited to the central section of the southwestern boundary of Area C and the Springfield Pike boundary of Area B. Further, the study was limited to a maximum depth of… more

Spent Fuel Transfer, Storage and Shipment for PL-3

Description: In refueling development studies performed on PL-3 Phase I design, several methods of fuel transfer, storage, and shipment were investigated. An evaluation of the relative merits of the systems and designs under study, as applied to either the BWR or PWR concepts, is made and optimum designs are selected. An analysis of spent fuel shipping cask shielding requirements is presented, along with recommendations for future study in this area. (auth)

Low strain diameter expansion of internally pressurized Zircaloy-4 tubing at high temperatures

Description: Tests of closed-end, internally pressurized, Zircaloy-4 tubing specimens were utilized to develop low strain creep characteristics as a function of time at temperatures in the range of 1475/sup 0/F to 2000/sup 0/F (802/sup 0/C to 1093/sup 0/C) and hoop stresses in the range of 250 to 2500 psi for use in loss-of-coolant accident (LOCA) analyses. The strain rate above the start of the alpha to beta phase transformation region, approximately 1490/sup 0/F (810/sup 0/C), was found to be sensitive to… more

Least cost planning from a customer's perspective

Description: In this paper, I offer some thoughts about least cost planning, not from the perspective of the regulator or utility, but from the perspective of a residential customer. The problem that I address is, as a homeowner in northern Virginia, I am about to make a long term fuel choice for my household, where the options include, natural gas, electricity and fuel oil. An additional choice is the energy efficiency capital investment in my home that could decrease my monthly fuel costs. My decision pro… more

TPC magnet cryogenic system

Description: The Time Projection Chamber (TPC) magnet at LBL and its compensation solenoids are adiabatically stable superconducting solenoid magnets. The cryogenic system developed for the TPC magnet is discussed. This system uses forced two-phase tubular cooling with the two cryogens in the system. The liquid helium and liquid nitrogen are delivered through the cooled load by forced tubular flow. The only reservoirs of liquid cryogen exist in the control dewar (for liquid helium) and the conditioner dewar… more

Cross sections for the /sup 7/Li(n,xn) and /sup 7/Li(n,n'. gamma. ) reactions between 1 and 20 MeV

Description: Differential cross sections for the production of secondary neutrons and gamma rays from neutron interactions in /sup 7/Li have been measured at 50/sup 0/ and 126/sup 0/ (lab) for incident neutron energies in the range 1 to 20 MeV. An electron linac was used as a white neutron source. Incident neutron energies were determined using time-of-flight techniques for a source-to-sample distance of 48 m. Secondary spectra were determined by analysis of the pulse-height distributions observed in a NE-2… more

Research and development of methods and tools for achieving and maintaining consensus processes in the face of change within and among government oversight agencies: Volume 1

Description: This progress report summarizes our research activities under our consensus grant. In year four of the grant, we continued to capitalize on and benefit from historical events which drove our early emphasis on group process studies. Following our work on various procedures for bringing together groups such as the State and Tribal Government Working Group and the Stakeholders' Forum (both of which provide input to the Five-Year Waste Plan), we continue to observe these groups and collect data. We… more

Penn Grade Micellar Displacement project. First annual report, June 1975--June 1976

Description: The main objective of the Penn Grade-ERDA Micellar Displacement Project is to assess and hopefully, demonstrate the feasibility of commercial application of the micellar-polymer process for tertiary oil recovery from a rather large, but relatively ''tight'' section of the Bradford Third Sand. The initial phase of this project involves pertinent core and field injectivity measurements from a freshly drilled well, as a basis for assessing the feasibility of a small demonstration test flood to be … more

Effects of low-temperature fusion neutron irradiation on critical properties of a monofilament niobium-tin superconductor

Description: The objective of this work was to irradiate a Nb/sub 3/Sn superconductor with 14.8 MeV neutrons at 4 K and measure critical current in transverse fields of up to 12 T, irradiating up to a fluence sufficient to decrease the critical current to below its initial value. Critical temperatures were also to be measured. The samples were to be kept near 4 K between the irradiation and the measurement of critical properties. This work is directed toward establishing an engineering design fluence limit … more
