Toxicological benchmarks for screening of potential contaminants of concern for effects on aquatic biota on the Oak Ridge Reservation, Oak Ridge, Tennessee

Description: This report presents potential screening benchmarks for protection of aquatic life from contaminants in water. Because there is no guidance for screening benchmarks, a set of alternative benchmarks is presented here. The alternative benchmarks are based on different conceptual approaches to estimating concentrations causing significant effects. For the upper screening benchmark, they are the acute National Ambient Water Quality Criterion (NAWQC) and the acute pesticide advisory value (a concent… more

Dynamics and Controls in Maglev Systems

Description: The dynamic response of magnetically levitated (maglev) ground transportation systems has important consequences for safety and ride quality, guideway design, and system costs. Ride quality is determined by vehicle response and by environmental factors such as humidity and noise. The dynamic response of the vehicles is the key element in determining ride quality, and vehicle stability is an important safety-related element. To design a proper guideway that provides acceptable ride quality in th… more

Green Products by Design: Choices for a Cleaner Environment

Description: In this report, OTA provides a conceptual overview of how designers might integrate environmental concerns with traditional design objectives, and how policymakers can best take advantage of such opportunities. Although the concept of “green” design is gathering momentum, a number of technical, behavioral, economic, and informational barriers need to be addressed.

Monitoring Limits on Sea-Launched Cruise Missiles

Description: This report examines in detail ways in which compliance with such a regime might be monitored. Surveying the life-cycle of SLCMs from development testing through deployment and storage, the assessment identifies the ‘indicators’ by which the missiles might be tracked and accounted for. It also assesses the paths of evasion that a determined cheater might take to avoid the proposed monitoring measures.

U.S.-Mexico Trade: Pulling Together or Pulling Apart?

Description: This report finds little likelihood that a NAFTA, by itself, will lead to the most dismal scenarios. But OTA’s analysis also indicates that market forces alone are not likely to produce the social and economic rewards the heads of both states have promised from a free trade agreement.

Implementation Plan for the Hawaii Geothermal Project Environmental Impact Statement (DOE Review Draft:)

Description: The US Department of Energy (DOE) is preparing an Environmental Impact Statement (EIS) that identifies and evaluates the environmental impacts associated with the proposed Hawaii Geothermal Project (HGP), as defined by the State of Hawaii in its 1990 proposal to Congress (DBED 1990). The location of the proposed project is shown in Figure 1.1. The EIS is being prepared pursuant to the requirements of the National Environmental Policy Act of 1969 (NEPA), as implemented by the President's Council… more

Transmission electron microscopy of Al-Li control rod pins

Description: This report discusses transmission electron microscopy employed to characterize the microstructures of both cast and mechanically alloyed powder Al-Li control rod pins. The results indicated that microstructural differences existed between the ingot and powder metallurgy materials. In general, the cast specimens contained large, dendritic [alpha] grains separated by regions of much smaller a grains and AlLi [beta] particles. The grain interiors, except in the immediate vicinity of the [beta] pa… more

Conversion of ethane and of propane to higher olefin hydrocarbons

Description: It has become apparent during the past few months that results obtained in the oxidative coupling of methane cannot be extended to ethane and propane. Good selectivities and yields for the oxydehydrogenation to olefins can be obtained but production of higher hydrocarbons is small. The present report summarizes results of experiments using zeolite based catalysts and compares these with basic oxide catalysts. The oxydehydrogenation of ethane over zeolite based catalysts (H[sup [minus plus]] Na[… more

Applicability of petroleum horizontal drilling technology to hazardous waste site characterization and remediation

Description: Horizontal wells have the potential to become an important tool for use in characterization, remediation and monitoring operations at hazardous waste disposal, chemical manufacturing, refining and other sites where subsurface pollution may develop from operations or spills. Subsurface pollution of groundwater aquifers can occur at these sites by leakage of surface disposal ponds, surface storage tanks, underground storage tanks (UST), subsurface pipelines or leakage from surface operations.

High energy decomposition of halogenated hydrocarbons

Description: This program is the INEL component of a joint collaborative effort with Lawrence Livermore National Laboratory (LLNL). Purpose is to demonstrate a viable process for breaking down hazardous halogenated organic wastes to simpler, nonhazardous wastes using high energy ionizing radiation. The INEL effort focuses on the use of spent reactor fuel gamma radiation sources to decompose complex wastes such as PCBS. Work in FY92 expanded upon that reported for FY91. During FY91 it was reported that PCBs … more

The comparison of DYNA3D to approximate solutions for a partially- full waste storage tank subjected to seismic loading

Description: Mathematical solutions to the problem consisting of a partially-full waste tank subjected to seismic loading, embedded in soil, is classically difficult in that one has to address: soil-structure interaction, fluid-structure interaction, non-linear behavior of material, dynamic effects. Separating the problem and applying numerous assumptions will yield approximate solutions. This paper explores methods for generating these solutions accurately.

Synthesis of octane enhancers during slurry-phase Fischer-Tropsch

Description: The objective of this project is to investigate three possible routes to the formation of ethers, in particular methyl tert-butyl (MTBE), during slurry phase Fischer-Tropsch reaction. The three reaction schemes to be investigated are: addition of i-butylene during the formation of methanol and/or higher alcohols directly from CO and H[sub 2] during slurry-phase Fischer-Tropsch; addition of i-butylene to FT liquid products including alcohols in a slurry-phase reactor containing an MTBE or other … more

Sampling and analysis of sediments in dredged material from Wilma Uplands Disposal Site

Description: The Lower Granite Reservoir provides slack-water navigation for the Lewiston, Idaho, and Clarkston, Washington area. The levee system associated with the reservoir protects industrial, commercial, and residential areas from inundation of waters impounded behind the dam. Sediment deposition at the confluence of the Snake and Clearwater rivers has required frequent dredging events In past years, Including two recent events in 1986 and 1987. Dredged material from the 1986 and 1987 events was place… more
