Feasibility of laser-separation of /sup 36/S and its use as an atmospheric tracer

Description: This report addresses one of the possible uses of isotopic tracers, produced by laser-assisted iostope separation, in the investigation of pollution problems. Specifically, the use of laser-produced sulfur isotopes to analyze the acid rain situation is considered as it is a most important application of this technique. The proposed use of isotopically-labelled SO/sub 2/, in particular of /sup 36/SO/sub 2/, as a tracer can help elucidate the chemical and transport facets in a unified experiment.… more

Guidelines for acceptable soil concentrations in the old F- and H-Area Retention Basins

Description: Concentration guidelines for residual radionuclides in soil at the sites of the Old F- and H-Area Retention Basins (281-3F, 281-3H) have been calculated using a dose-based approach. The guidelines also are being applied to areas around the F-Basin`s Process Line. Estimation of these soil guidelines was completed using RESRAD 5.0 in accordance with the DOE RESRAD methodology specified in DOE/CH/8901 (Gi89). Guidelines are provided for the nuclides known to be present in the soils at each basin (… more

Comment on"Air Emissions Due to Wind and Solar Power" and Supporting Information

Description: Katzenstein and Apt investigate the important question of pollution emission reduction benefits from variable generation resources such as wind and solar. Their methodology, which couples an individual variable generator to a dedicated gas plant to produce a flat block of power is, however, inappropriate. For CO{sub 2}, the authors conclude that variable generators 'achieve {approx} 80% of the emission reductions expected if the power fluctuations caused no additional emissions.' They find even… more

Turbulence Kinetic Energy Budgets and Dissipation Rates in Disturbed Stable Boundary Layers

Description: An important parameter in the numerical simulation of atmospheric boundary layers is the dissipation length scale, l{sub {var_epsilon}}. It is especially important in weakly to moderately stable conditions, in which a tenuous balance between shear production of turbulence, buoyant destruction of turbulence, and turbulent dissipation is maintained. In large-scale models, the dissipation rate is often parameterized using a diagnostic equation based on the production of turbulent kinetic energy (T… more

The Case for Hydrogen in a Carbon Constrained World

Description: Unlike other fuels, hydrogen (H{sub 2}) can be generated and consumed without generating carbon dioxide (CO{sub 2}). This creates both significant engineering challenges and unsurpassed ecological advantages for H{sub 2} as a fuel, while enabling an inexhaustible (closed) global fuel cycle based on the cleanest, most abundant, natural, and elementary substances: H{sub 2}, O{sub 2}, and H{sub 2}O. If generated using light, heat, and/or electrical energy from solar, wind, fission, or (future) fus… more

Accelerator production of tritium pollution prevention design assessment

Description: This Pollution Prevention Design Assessment (PPDA) provides data for cost-benefit analysis of the potential environmental impact of the APT, is an integral part of pollution prevention/waste minimization, and is required by DOE for any activity generating radioactive, hazardous, and mixed wastes. It will also better position the APT to meet future requirements, since it is anticipated that regulatory and other requirements will continue to become more restrictive and demanding.

Spring 1995 wildlife and vegetation survey, Norton Air Force Base, California

Description: The objectives of the 1994 and 1995 wildlife and vegetation surveys were to gather data to be used for various applications including: (1) basewide Environmental Risk Assessment (ERA) Work Plan (Scoping Document), (2) the completion of the basewide ERA, (3) determining remedial activities, and (4) determining the distribution of state and federal list plant and animal species on Norton AFB. Data gathering included an inventory of plant and animal species present, the identification of potential… more
