45-Day safety screen results for Tank 241-C-101, auger sample 95-AUG-019

Description: One auger sample from Tank 241-C-101 was received by the 222-S Laboratory and underwent safety screening analyses--differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and total alpha analysis--in accordance with the tank characterization plan. Analytical results for the TGA on the crust sample (the uppermost portion of the auger sample) (sample number S95T000823) were less than the safety screening notification limit of 17 weight percent water.

Advances in Scientific Visualization

Description: This paper discusses scientific visualization of scalar and vector fields, particularly relating to clouds and climate modeling. One cloud rendering method applies a 3-D texture to cloudiness contour surfaces, to simulate a view from outer space. The texture is advected by the wind flow, so that it follows the cloud motion. Another technique simulates multiple scattering of incident light from the sun and sky. This paper also presents a simulation of the microscopic cross-bridge motion which po… more

China's Changing Conditions

Description: This report discusses congressional interest in the leadership change and economic transformation underway in China, which has grown substantially over the past two years. Leading congressional concerns focus on how economic conditions in China pose opportunities for U.S. enterprise and how the evolution of conditions in China foster U.S. security, economic, and political interests. Congressional concern with China grew in 1995 as a result of reports of the serious decline in the health of seni… more

Configuring NIF for direct drive experiments

Description: The National Ignition Facility (NIF) is a proposed 1.8 MJ laser facility for carrying out experiments in inertial confinement fusion, currently designed for indirect drive experiments. The direct drive approach is being pursued at the 30 kJ Omega facility at the University of Rochester. In this paper we discuss the modifications to the NIF laser that would be required for both indirect and direct drive experiments. A primary concern is the additional cost of adding direct drive capability to th… more

Criticality safety evaluation for long term storage of FFTF fuel in interim storage casks

Description: It has been postulated that a degradation phenomenon, referred to as ``hot cell rot``, may affect irradiated FFTF mixed plutonium-uranium oxide (MOX) fuel during dry interim storage. ``Hot cell rot`` refers to a variety of phenomena that degrade fuel pin cladding during exposure to air and inert gas environments. It is thought to be a form of caustic stress corrosion cracking or environmentally assisted cracking. Here, a criticality safety analysis was performed to address the effect of the ``h… more

Destruction of VX by aqueous-phase oxidation using peroxydisulfate (direct chemical oxidation)

Description: Chemical warfare agents may be completely destroyed (converted to H{sub 2}O, CO{sub 2}, salts) by oxidation at 90--100 C using acidified ammonium peroxydisulfate, with recycle of NH{sub 4}SO{sub 4} byproduct. The process requires no toxic or expended catalysts and produces no secondary wastes other than the precipitated inorganic content of the agents. To determine oxidative capability of peroxydisulfate at low reductant contents, we measured rate data for oxidation of 20 diverse compounds with… more

Development of a cable reel development system using a rotary joint for kilometer lengths of two-fiber multi-mode fiber optic cable

Description: Brookhaven National Laboratory (BNL) recently developed a two-component system for use during remote inspections. The system consists of a mobile unit with television cameras and other equipment and a stationary base station. A variety of signals must be continually transmitted between the two system components as the mobile unit is moved from the location to another. Two channels of broadband (10MHz) NTSC video are transmitted from the mobile unit to the base station, and a bi-directional ``ta… more

Diode-pumped solid-state laser driver experiments for inertial fusion energy applications

Description: Although solid-state lasers have been the primary means by which the physics of inertial confinement fusion (ICF) have been investigated, it was previously thought that solid-state laser technology could not offer adequate efficiencies for an inertial fusion energy (IFE) power plant. Orth and co-workers have recently designed a conceptual IFE power plant, however, with a high efficiency diode-pumped solid-state laser (DPSSL) driver that utilized several recent innovations in laser technology. I… more

Direct chemical oxidation of hazardous and mixed wastes

Description: Direct Chemical Oxidation (DCO) refers to the use of continuously-regenerated peroxydisulfate (with possible hydrogen peroxide supplements) to effect total destruction of organic wastes in aqueous media. The process does not involve toxic catalysts or the cogeneration of secondary wastes. Peroxydisulfate (S{sub 2}O{sub 8}{sup -2}) is one the strongest known chemical oxidants. It is routinely used in laboratory total carbon analyzers--uncatalyzed at 100{degrees}C, or catalyzed by UV, platinum or… more

Electronic Denitration Savannah River Site Radioactive Waste

Description: Electrochemical destruction of nitrate in radioactive Savannah River Site Waste has been demonstrated in a bench-scale flow cell reactor. Greater than 99% of the nitrate can be destroyed in either an undivided or a divided cell reactor. The rate of destruction and the overall power consumption is dependent on the cell configuration and electrode materials. The fastest rate was observed using an undivided cell equipped with a nickel cathode and nickel anode. The use of platinized titanium anode … more

Environmental assessment of the relocation of Neutron Tube Target Loading Operations. Final document

Description: Neutron Tube Target Loading (NTTL) is an operation that involves the transferring (i.e. loading) of radioactive tritium gas onto metal target disks under an inert nitrogen atmosphere using a glovebox operation. The relocation of NTTL operations from the Pinellas Plant to the Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, was addressed in the Non-nuclear Consolidation Environmental Assessment (EA) of June 1993. This EA analyzes a Proposed Action to relocate the NTTL operations … more

Evaluation of gas-reburning and low NO{sub x} burners on a wall fired boiler. Technical progress report No. 19, April 1, 1995--June 30, 1995

Description: Clean Coal Technology (CCT) implies the use of coal in an environmentally acceptable manner. Coal combustion results in the emission of oxides of nitrogen (NO{sub x}), which are precursors of both acid rain and ozone formation. The primary objective of this CCT project is to evaluate the use of Gas Reburning and Low NO{sub x} Burners (GR-LNB) for NO{sub x} emission control from a wall fired boiler. It is anticipated that, if the demonstration is successful, the GR-LNB technology could become co… more
