Waste Trade and the Basel Convention: Background and Update

Description: The United States played a major role in developing the 1989 United Nations-sponsored Basel Convention on the Control of the Transboundary Movement of Hazardous Wastes and Their Disposal, a key purpose of which is to protect countries from receiving unwanted shipments of wastes. The Convention entered into force in 1992, and by mid-1998, 121 countries (but not the United States) had ratified it. In 1991, the Bush Administration transmitted the Convention to the Senate for advice and consent to … more

Brief Summaries of Federal Animal Protection Statutes

Description: This report contains brief summaries of federal animal protection statutes, listed alphabetically. It does not include treaties, although it does include statutes enacted to implement treaties. It includes statutes concerning animals that are not entirely, or not at all, animal protection statutes. For example, it includes a statute authorizing the eradication of predators, because one of the statute's purposes is to protect domestic and "game, animals; and it includes statutes to conserve fish… more

Combining the Best of Bulk and Surface Micromaching Using Si(111) Substrates

Description: This process combines the best features of bulk ad surface micromachining. It enables the production of stress free, thick, virtually arbitrarily shaped structures with well defiti thick or thin sacrificial layers, high sacrificial layer selectivity and large undercuts using IC compatible, processes. The basis of this approach is the use of dy available {111} oriented substrates. anisotropic Si trench etching, S iN masking and KOH etching.

Completion of the ATLAS control system upgrade.

Description: In the fall of 1992 at the SNEAP(Symposium of North Eastern Accelerator Personnel) a project to up grade the ATLAS (Argonne Tandem Linear Accelerator System) control system was first reported. Not unlike the accelerator it services the control system will continue to evolve. However, the first of this year has marked the completion of this most recent upgrade project. Since the control system upgrade took place during a period when ATLAS was operating at a record number of hours, special techni… more

Delamination detection in reinforced concrete using thermal inertia

Description: We investigated the feasibility of thermal inertia mapping for bridge deck inspections. Using pulsed thermal imaging, we heat-stimulated surrogate delaminations in reinforced concrete and asphalt-concrete slabs. Using a dual-band infrared camera system, we measured thermal inertia responses of Styrofoam implants under 5 cm of asphalt, 5 cm of concrete, and 10 cm of asphalt and concrete. We compared thermal maps from solar-heated concrete and asphalt-concrete slabs with thermal inertia maps from… more

Development of a ceramic waste form for high-level waste disposal.

Description: A ceramic waste form is being developed by Argonne National Laboratory (ANL) as part of the demonstration of the electrometallurgical treatment of spent nuclear fuel. The halide, alkaline earth, alkali, transuranic, and rare earth fission products are stabilized in zeolite which is combined with glass and processed in a hot isostatic press (HIP) to form a ceramic composite. The mineral sodalite is formed in the HIP from the zeolite precursor. The process, from starting materials to final produc… more

Direct-Write Precision Resistors for Ceramic Packages

Description: A direct-write approach to f abricate high precision resistors is reported. Special attention is paid to the effect of print thickrw;s on the resistance value of buried resistors after a low temperature co-firing process. The results show that the direct-write approach provides a superior line definition and thickness control over a traditional screen printing process. Microstructural analysis indicates that there is an interdiffused layer developed between the resistor material and the low tem… more

Drain Holes for Criticality Safety Control Guidance for the Analyst

Description: Drain and overflow holes are integral to the nuclear criticality safety basis of many processes and provide different functions in achieving their safety goal. In most cases, unverified engineering judgement was used to conclude that the holes were adequate to accomplish their mission. Such judgement may adequately serve some configurations but is inadequate in other applications. It was determined that the exact function of every hole for both normal and upset process conditions must be unders… more

Effect of Low Temperature Ion Irradiation on the Microstructure of Nitride Ceramics

Description: Cross-section transmission electron microscopy was used to investigate the microstructure of polycrystalline silicon nitride (Si{sub 3}N{sub 4}) and aluminum nitride (AlN) following 2 MeV Si ion irradiation at 80 and 400 K up to a fluence of 4 x 10{sup 20} ions/m{sup 2} (maximum damage of {approximately}10 displacements per atom, dpa). A buried amorphous band was observed at both temperatures in Si{sub 3}N{sub 4} in the region corresponding to the peaks in the implanted ion and displacement dam… more

Effect of Small Amounts of B and C Additions on Glass Formation and Mechanical Properties of a Zr-Base Alloy

Description: The effect of B and C additions up to 0.4 at. % on glass formation and mechanical properties of a Zr-base alloy Vitreloy 105 was studied using various techniques. All alloys were prepared by arc melting and drop casting. Boron additions increase the glass forming ability by lowering T<sub>m</sub> and increasing T<sub>g</sub>. Carbon additions only lower T<sub>m</sub>, but do not affect T<sub>g</sub>. B and C additions occupy free space and do not harden the glass phase.

Fourier transform photoelectron diffraction and its application to molecular orbitals and surface structure

Description: Photoemission intensities from the molecular orbitals of c(2x2)CO/Pt(111) over a wide photon energy range were measured and analyzed by the same methods developed for structural studies using core levels. The 4{sigma} orbital center of gravity is found to be concentrated between the C and O atoms, while that of the 5{sigma} orbital lies between the C atom and the Pt surface. The C 1s photoelectron diffraction was used to determine the adsorption geometry. The earlier ambiguity that multiple sca… more

Fracture in Bulk Amorphous Alloys

Description: The fracture behavior of a Zr-based bulk amorphous alloy, Zr-10 AI-5 Ti-17.9 Cu-14.6 Ni, was examined by transmission electron microscopy (TEM) and x-ray diffraction for any evidence of crystallization preceding crack propagation. No evidence for crystallization was found in shear bands in compression specimens or at the fracture surface in tensile specimens. In- situ TEM deformation experiments were performed to more closely examine actual crack tip regions. During the in-situ deformation expe… more

From Molecular Dynamics to Kinetic Rate Theory: A Simple Example of Multiscale Modeling

Description: Radiation damage formation in iron has been investigated using the method of molecular dynamics simulation. The MD simulations have been used to determine primary defect production parameters for cascade energies up to 50 keV at temperatures from 100 to 900K. The energy dependence of these parameters has been used to determine appropriate neutron-energy-spectrum averaged damage production cross sections for various irradiation environments. Two applications of these effective cross sections are… more

In-beam production and transport of radioactive {sup 17}F at ATLAS.

Description: Beam currents of radioactive {sup 17}F(T{sub 1/2} = 65s) as high as 2 x 10{sup 6} s{sup {minus}1} have been produced at the ATLAS facility and delivered to target for nuclear physics research. The d({sup 16}O, {sup 17}F)n and p({sup 17}O,{sup 17}F)n reaction were used to produce the {sup 17}F in the energy range of 65-110 MeV with {sup 17}F intensities of up to 250 pnA. The target employed is a liquid nitrogen cooled H{sub 2} gas cell, with HAVAR windows, operating at up to 8 x 10{sup 4} Pa pre… more

Influence of microstructural properties on geophysical measurements in sand-clay mixtures

Description: We have performed a series of laboratory experiments on saturated sand-clay mixtures. Measurements include frequency-dependent electrical properties using the four-electrode technique (10 niHz to 1 MHz), permeability, porosity, and acoustic velocities. We mixed clean Ottawa (quartz) sand with Na-montmorillonite (Wyoming bentonite) in a number of different configurations containing 0 to 10% clay: as a dispersed mixture, as discrete clay clusters, and arranged in distinct layers. Solutions of CaC… more
