Clustering of radioactive tank waste data and comparison to historical models

Description: The US Department of Energy (DOE) has initiated remediation for stored high-level radioactive wastes. At the DOE Hanford site in southeastern Washington, 149 large underground tanks contain such wastes, generated by various chemical processes during the manufacture of plutonium for nuclear weapons. One of the key steps in this remediation effort is to characterize the waste stored in these tanks so that it can be treated properly and safely. A number of samples have been extracted from a subset… more

Finite element modeling of the effect of interface anomalies on thermal stresses in alumina scales.

Description: The scales that grow from oxidation often develop a convoluted morphology or interface pores. High thermal stresses can develop locally and are potentially detrimental to the scale or interface integrity. Finite element simulations are used to examine residual thermal stresses and strains that result when these deviations from a flat interface have formed, and the resulting geometry is subsequently cooled to room temperature. A variety of geometries will be considered for alumina scales on a Fe… more

Identification of methanococcus jannaschii proteins in 2-D gel electrophoresis patterns by mass spectrometry.

Description: The genome of Methanococcus jannaschii has been sequenced completely and has been found to contain approximately 1,770 predicted protein-coding regions. When these coding regions are expressed and how their expression is regulated, however, remain open questions. In this work, mass spectrometry was combined with two-dimensional gel electrophoresis to identify which proteins the genes produce under different growth conditions, and thus investigate the regulation of genes responsible for function… more

Stormwater Permits: Status of EPA's Regulatory Program

Description: The Environmental Protection Agency (EPA) and states are implementing a federally mandated program for controlling stormwater discharges from industrial plants and municipalities. Because of the large number of affected sources and deadline changes and extensions that have led to confusion, numerous questions have arisen about this program. Impacts of the program;s requirements, especially on cities, are a continuing concern. EPA has recently proposed permit rules to cover smaller cities and so… more

Highway Funding, the States, and New Air Quality Standards

Description: The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), PL. 102-240, set aside $6 billion from FY1992 to FY1997 for the Congestion Mitigation and Air Quality Program (CMAQ) to assist states in complying with federal air quality standards by funding transportation projects that lower emissions.

The Chip Mill Industry in the South

Description: Chip mills turn trees into chips for paper, particle-boards, and exports. While the federal government does not collect data on a chip mill industry, chip production in the South has apparently been expanding. The timber supply appears sufficient to allow some increased harvests, but could be depleted by continued industrial expansion. The federal government does not directly regulate timber cutting but could become engaged if requirements of the Clean Water and Endangered Species Acts were tri… more

Restructuring Electricity Markets, Public Power, and Tax-Exempt Bonds: An Economic Analysis

Description: Tax-exempt bonds subsidize public power's cost of capital and enable it to lower price. The subsidy is economically beneficial (enables public power price to reflect the true cost of electric service) only if the private market fails to provide the correct amount of electricity. In general, the private market does provide the correct amount of electricity; in those cases when it does not, the tax-exempt bond subsidy is unlikely to correct the problem. Tax-exempt bond legislation over the last 3… more

Hong Kong After Its Return to China: Implications for US Interests

Description: Hong Kong's return to China on July 1, 1997, went surprisingly smoothly. In the ensuing months, policy analysts are trying to assess how the territory will fare in the longer run under Chinese rule. The answer is important to U.S. interests because of the enormous U.S. economic presence in Hong Kong; because any adverse developments in Hong Kong are likely to affect U.S.-China relations; and because China's promise to give Hong Kong a high degree of autonomy under the "one-China, two-systems" p… more

Adiabatic interpretation of particle creation in a de Sitter universe

Description: The choice of vacuum state for a quantum scalar field propagating in a de Sitter spacetime (massive and arbitrarily coupled to the gravitational field) is discussed. The problem of finite-time initial conditions for the mode functions is analyzed, as well as how these determine the vacuum state of the quantum system. The principle guiding the choice of vacuum state is the following: one wants the vacuum contribution to the energy-momentum tensor to contain all the ultraviolet divergent terms, s… more

Beam control and laser characterization for NIF

Description: The demanding energy, power, pulse shape, focusability, pointing, and availability requirements placed on the 192 National Ignition Facility (NIF) beams lead to the need for an automatic operation capability that is well beyond that of previous inertial confinement fusion (ICF) lasers. Alignment, diagnostic, and wavefront correction subsystems are integrated in an approach that, by permitting maximal sharing of instrumentation between subsystems, meets performance requirements at a reasonable c… more

Neutron Activation Cool-down of the Tokamak Fusion Test Reactor

Description: Tokamak Fusion Test Reactor (TFTR) final operations and post-shutdown neutron activation measurements were made. Ionization chambers were used to follow TFTR activation during operations and after shutdown. Gamma-ray energy spectroscopy measurements were performed to characterize TFTR activation at accessible vessel-bays and on sample hardware removed from structures at various distances from the vessel. The results demonstrate long-lived activations from common, commercially available material… more

SEEPAGE INTO DRIFTS IN UNSATRUATED FRACTURED ROCK AT YUCCA MOUNTAIN

Description: An important issue for the long-term performance of underground nuclear waste repositories is the rate of seepage into the waste emplacement drifts. A prediction of the future seepage rate is particularly complicated for the potential repository site at Yucca Mountain, Nevada, as it is located in thick, partially saturated, fractured tuff formations. The long-term situation in the drifts several thousand years after waste emplacement will be characterized by a relative humidity level close to o… more

Determination of nitrate and nitrite in Hanford defense waste(HDW) by reverse polarity capillary zone electrophoresis (RPCE)method

Description: This paper describes the first application of reverse polarity capillary zone electrophoresis (RPCE) for rapid and accurate determination of nitrate and nitrite in Hanford Defense Waste (HDW). The method development was carried out by using Synthetic Hanford Waste (SHW), followed by the analysis of 4 real HDW samples. Hexamethonium bromide (HMB) was used as electroosmotic flow modifier in borate buffer at pH 9.2 to decrease the electroosmotic flow (EOF) in order to enhance the speed of analysis… more

Simplified analytic formula for magneto-optical Kerr effects in ultrathin magnetic films.

Description: Expressions are presented for various magneto-optical Kerr effects in the ultrathin film limit with arbitrary magnetization direction by considering the multiple reflections within an optically thin film. The Kerr effect of p- and s-polarization consists of products of two factors: the prefactor, dependent only on the optical parameters of the system, and the main factor of the polar Kerr effect for normal incidence in the ultrathin limit.
