Development of mild gasification process

Description: Under a previous contract with Morgantown Energy Technology Center (METC), Department of Energy (DOE) Contract No. AC21-84MC21108, UCC Research Corporation (UCCRC) built and tested a 1500 lb/day Mild Gasification Process Development Unit (MGU). The MGU, as tested under the previous contract, is shown in Figure 1. Testing completed under the previous contract showed that good quality hydrocarbon liquids and good quality char can be produced in the MGU. However, the MGU is not optimized. The prim… more

Geomembrane special study. [UMTRA Project]

Description: The objective of the Geomembrane Special Study was to asses the suitability of geomembranes in Uranium Mill Tailings Remedial Action (UMTRA) Project pile designs. Geomembranes, also called flexible membrane liners, are made of polymer resins and are thermoplastic materials. Part of the special study was to evaluate regulatory compliance and acceptability issues. This study was proposed because of the extensive use of geomembranes in hazardous waste site remedial actions and their accepted use i… more

Behavior of power-limited transverse stochastic cooling systems

Description: Analysis of stochastic cooling systems is usually done under the assumption that the system performance is not limited by the available electronic gain. In practical systems, it may prove to be the case that cost-induced limitations on the maximum available output power restrict the maximum attainable gain, thereby restricting it to be less than its optimal value. Such is the case in the anti-proton sources at both CERN and Fermilab. The criteria that one would employ in, for example, upgrading… more

Simulations of the near-field transport of radionuclides by liquid diffusion at Yucca Mountain: Comparisons with and without emplacement backfill. [Yucca Mountain Project]

Description: The possible set of hydrologic conditions at the Yucca Mountain repository site includes the case where groundwater recharge fluxes are sufficiently low relative to molecular diffusion in the rock so that, in the region around the waste package, the dominant mode of aqueous transport of radionuclides is by diffusion. Although the rock at the repository level is unsaturated, a sufficient amount of pore water could form a contiguous diffusion path from the waste form to the near-field rock if the… more

Use of cermet fueled nuclear reactors for direct nuclear propulsion

Description: There has been a renewal of interest in Direct Nuclear Propulsion (DNP) because of the Air Force Forecast II recommendation for the development of the technology. Several nuclear concepts have been proposed to meet the Direct Nuclear Propulsion challenge. In this paper we will present results of an initial study of the potential of a cermet fueled nuclear system in providing the desired DNP capabilities and featuring a set of unique safety characteristics. The concept of cermet fuel for DNP app… more

In situ experiments of geothermal well stimulation using gas fracturing technology

Description: The results of an experimental study of gas fracturing technology for geothermal well stimulation demonstrated that multiple fractures could be created to link water-filled boreholes with existing fractures. The resulting fracture network and fracture interconnections were characterized by mineback as well as flow tests. Commercial oil field fracturing tools were used successfully in these experiments. Simple scaling laws for gas fracturing and a brief discussion of the application of this tech… more

Transport simulations of ohmic pellet experiments on the TFTR, ASDEX, and ALCATOR-C tokamaks

Description: Transport simulations of ohmic gas-fuelled and pellet-fuelled experiments have been carried out to test a microinstability-based, profile-consistent model of anomalous transport in tokamaks. Predictions for experiments on the TFTR, ASDEX, and ALCATOR-C tokamaks were found consistent with the observed confinement and temperature measurements. 26 refs., 11 figs., 10 tabs.

Prospects for understanding the astrophysical r-process

Description: This paper discusses several recent advances toward a deeper understanding of the still unknown astrophysical site for rapid (r-process) neutron capture nucleosynthesis. The physical constraints on the r-process from the input nuclear data are highlighted and the particular importance of the recent measurements of beta-decay lifetimes along the r-process path is discussed. Astronomical observations of s- and r-process elemental abundances on metal poor halo stars are also discussed, in the cont… more

Intermediate-range order in binary and ternary glasses

Description: Intermediate-range order in binary and ternary chalcogenide glasses is discussed, with special reference to GeSe/sub 2/ and Ag/sub 4/Ge/sub 3/Se/sub 9/. A signature of this order is provided by the first sharp diffraction peak, which occurs in these glasses at Q /approximately/ 1 /sup /angstrom/A//sup /minus/1/ and shows anomalous behavior in several ways. It is strongly depressed by the addition of Ag to the GeSe/sub 2/ glass. The addition of Ag also leads to a softening of the vibrational spe… more

Alpha storage regime in high temperature sub-ignited D-T tokamaks

Description: Alpha particle parameters in sub-ignited D-T tokamaks like TFTR can be optimized in a high temperature ''alpha storage regime '' in which the alpha particle thermalization time /tau//sub ..cap alpha../ is long (approx.1.0 sec) and in which the alpha particle source rate S/sub ..cap alpha../ is enhanced due to a beam-target and beam-beam reactions (by a factor of approx.2-3).

Bunch coalescing and bunch rotation in the Fermilab Main Ring: Operational experience and comparison with simulations

Description: The Fermilab Tevatron I proton-antiproton collider project requires that the Fermilab Main Ring produce intense bunches of protons and antiprotons for injection into the Tevatron. The process of coalescing a small number of harmonic number h=1113 bunches into a single bunch by bunch-rotating in a lower harmonic rf system is described.The Main Ring is also required to extract onto the antiproton production target bunches with as narrow a time spread as possible. This operation is also discussed.… more

Response of materials to high heat fluxes during operation in fusion reactors

Description: Very high energy deposition on first wall and other components of a fusion reactor is expected due to plasma instabilities during both normal and off-normal operating conditions. Off-normal operating conditions result from plasma disruptions where the plasma loses confinement and dumps its energy on the reactor components. High heat flux may also result from normal operating conditions due to fluctuations in plasma edge conditions. This high energy dump in a short time results in very high surf… more

PINEX (Pinhold Neutron Experiment) fluor characteristics

Description: This report will describe recent experiments to characterize four fluors: BC-400, 408, 422, 430. Each fluor sample was 0.5 cm thick commensurate with our standard Electronic Pinhole Neutron Experiment (EL-PINEX) fluors. The important results are that the neutron-gamma sensitivity ratios did not change significantly, although the absolute gamma and neutron sensitivities decreased. 6 figs., 4 tabs.

An investigation to define the physical/chemical constraints which limit NO sub x emission reduction achievable by reburning

Description: Reburning is a combustion modification technique which removes NO{sub x} from combustion products by using fuel as a reducing agent. Previous studies have shown that natural gas is more effective than coal as a reburning fuel. Objectives of this program are to define the chemical and physical constraints which prevent the attainment of 80% NO{sub x} reduction with reburning and to test improved configurations for reburning as an advanced NO{sub x} control technique for coal-fired boilers.
