AN-107 entrained solids - Solubility versus temperature
This report describes the results of a test conducted by Battelle to assess the solubility of the solids entrained in the diluted AN-107 low-activity waste (LAW) sample. BNFL requested Battelle to dilute the AN-107 sample using sodium hydroxide and de-ionized water to mimic expected plant operating conditions. BNFL further requested Battelle to assess the solubility of the solids present in the diluted AN-107 sample versus temperature conditions of 30, 40, and 50 C. BNFL requested these tests to assess the composition of the LAW supernatant and solids versus expected plant-operating conditions.

2000 Census: Answers to Hearing Questions on the Status of Key Operations
Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the status of the Bureau of the Census' key census operations, focusing on: (1) whether the Bureau followed GAO's recommendations and adopted an alternate form of contingency planning instead of relying on Congress for a supplemental appropriation; (2) why the census is such a local endeavor; (3) whether the Bureau will be able to translate the high level of public awareness into participation for the 2000 Census; (4) whether partnership specialists will be stretched too thinly to have a successful impact on the 2000 Census; (5) the challenges facing the Bureau in conducting a timely and accurate followup; (6) how the Bureau could intentionally or unintentionally cut corners to get the nonresponse follow-up workload done in a shorter period of time; and (7) the risks that could jeopardize the release of timely data."

Abstraction of Drift-Scale Coupled Processes
This Analysis/Model Report (AMR) describes an abstraction, for the performance assessment total system model, of the near-field host rock water chemistry and gas-phase composition. It also provides an abstracted process model analysis of potentially important differences in the thermal hydrologic (TH) variables used to describe the performance of a geologic repository obtained from models that include fully coupled reactive transport with thermal hydrology and those that include thermal hydrology alone. Specifically, the motivation of the process-level model comparison between fully coupled thermal-hydrologic-chemical (THC) and thermal-hydrologic-only (TH-only) is to provide the necessary justification as to why the in-drift thermodynamic environment and the near-field host rock percolation flux, the essential TH variables used to describe the performance of a geologic repository, can be obtained using a TH-only model and applied directly into a TSPA abstraction without recourse to a fully coupled reactive transport model. Abstraction as used in the context of this AMR refers to an extraction of essential data or information from the process-level model. The abstraction analysis reproduces and bounds the results of the underlying detailed process-level model. The primary purpose of this AMR is to abstract the results of the fully-coupled, THC model (CRWMS M&O 2000a) for effects on …

ADVANCED SORBENT DEVELOPMENT PROGRAM DEVELOPMENT OF SORBENTS FOR MOVING-BED AND FLUIDIZED-BED APPLICATIONS
The integrated gasification combined cycle (IGCC) power system using high-temperature coal gas cleanup is one of the most promising advanced technologies for the production of electric power from coal in an environmentally acceptable manner. Unlike conventional low-temperature cleanup systems that require costly heat exchangers, high-temperature coal gas cleanup systems can be operated near 482-538 C (900-1000 F) or higher, conditions that are a closer match with the gasifier and turbine components in the IGCC system, thus resulting is a more efficient overall system. GE is developing a moving-bed, high-temperature desulfurization system for the IGCC power cycle in which zinc-based regenerable sorbents are currently being used as desulfurization sorbents. Zinc titanate and other proprietary zinc-based oxides are being considered as sorbents for use in the Clean Coal Technology Demonstration Program at Tampa Electric Co.'s (TECo) Polk Power Station. Under cold startup conditions at TECo, desulfurization and regeneration may be carried out at temperatures as low as 343 C (650 F), hence a versatile sorbent is desirable to perform over this wide temperature range. A key to success in the development of high-temperature desulfurization systems is the matching of sorbent properties for the selected process operating conditions, namely, sustainable desulfurization kinetics, high …

The advanced tangentially fired combustion techniques for the reduction of nitrogen oxides (NOx) emissions from coal-fired boilers demonstration project: A DOE assessment
This document serves as a DOE post-project assessment of a project in Round 2 of the Department of Energy's Clean Coal Technology (CCT) Program: ``Advanced Tangentially Fired Combustion Techniques for the Reduction of Nitrogen Oxides (NO{sub x}) Emissions From Coal-Fired Boilers Demonstration Project''. In September 1990, Southern Company Services entered into an agreement to conduct the study, with Gulf Power Company providing the 180 megawatt electric (MWe) host site and ABB C-E Services Inc. providing the technology to be demonstrated. This project was undertaken to evaluate the nitrogen oxides (NO{sub x}) reduction potential of several variations of the Low NO{sub x} Concentric Firing System (LNCFS{trademark}) when applied to tangentially fired (T-fired) boilers. The project consisted of replacing the existing coal and air nozzles with new nozzles and adding overfire air. Three versions of the LNCFS system were tested: Level 1 consisted of new coal nozzles and close-coupled overfire air; Level 2 used the same burners but separated the overfire air; and Level 3 used both close-coupled and separated overfire air. The performance objectives were as follows: (1) to determine the short-term and long-term NO{sub x} emissions reduction capabilities and impact on unit performance of the low-NO{sub x} combustion technologies of …

Air Pollution: Emission Sources Regulated by Multiple Clean Air Act Provisions
A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the regulatory programs that target specific pollutants or sources of pollution under the 1990 Clean Air Act Amendments, focusing on: (1) examples of emission sources subject to regulation under more than one program authorized by the act; and (2) the status of the Environmental Protection Agency's (EPA) efforts to facilitate compliance for such sources."

Air Quality and Electricity: Enforcing New source Review
This report discusses seven law suits that the Justice Department filed against electric utilities in the Midwest and South in violation of the New Source Review (NSR) and Clean Air Act (CAA). The EPA is attempting to use the NSR and CAA to reduce emissions, even thought they believe that some sources are evading NSR requirements.

An Alternative Host Matrix Based on Iron Phosphate Glasses for the Vitrification of Specialized Waste Forms
As mentioned above, the overall goal of this research project was to collect the scientific information essential to develop iron phosphate glass based nuclear wasteforms. The specific objectives of the project were: (1) Investigate the structure of binary iron phosphate glasses and it's dependence on the composition and melting atmosphere: Understand atomic arrangements and nature of the bonding. Establish structure-property relationships. Determine the compositions and melting conditions which optimize the critical properties of the base glass. (2) Understand the structure of iron phosphate wasteforms and it's dependence on the composition and melting atmosphere: Investigate how the waste elements are bonded and coordinated within the glass structure. Establish structure-property relationships for the waste glasses. Determine the compositions and melting atmosphere for which the critical properties of the waste forms would be optimum. (3) Determine the role(s) played by the valence states of iron ions and it's dependence on the composition and melting atmosphere: Understand the different roles of iron(II) and iron(III) ions in determining the critical properties of the base glass and the waste forms. Investigate how the iron valence and its significance depend on the composition and melting atmosphere. (4) Investigate glass forming and crystallization processes of the iron phosphate …
