CaO interaction in the staged combustion of coal

Description: The LIMB (limestone injection multi-stage burner) process offers special potential for reducing NO/sub x/ and SO/sub x/ by at least 50 percent in coal combustion. This is to be accomplished by adding limestone with fuel and/or air in a low NO/sub x/ burner. This program has been directed to defining the chemistry and kinetics necessary to optimize sulfur capture in LIMB combustion. More specifically, this program has attempted to clarify the role of calcium sulfide in LIMB chemistry. When limes… more

Caribbean Basin Initiative

Description: The Reagan Administration has proposed legislation which would seek to use trade and aid to promote political stability and economic growth in the Caribbean Basin region. Among other things, it would create a one-way free trade zone, where the small nations of the region would have an opportunity for export-led growth through duty-free access to the U.S. market. It would also provide $350 million in economic aid for 1982 to El Salvador and other Caribbean countries.

Demonstration of in-tank sludge processing: Part 2, Effect of processing on radionuclides

Description: The scope and cost of the Defense Waste Processing Facility have been significantly reduced by adding in-tank sludge processing to the process flowsheet. A demonstration of in-tank processing was recently completed and the achievement of the major goals described in a previous memo. This memo describes the effect of in-tank sludge processing on the radionuclides in the waste. This memo will also identify those areas that will require further work both before and during the next scheduled in-tan… more

Disposal of United Nuclear Company materials at the Y-12 Plant

Description: The UNC Recovery Systems Company, located at Wood River Junction, Rhode Island, was involved in the recovery of enriched uranium from scrap materials generated primarily in defense program activities of the DOE and its predecessor agencies. Following shutdown of the recovery operations in August 1980, UNC was required to decontaminate facilities and the associated waste lagoon systems and to remove the resultant low-level radioactive waste out of the state of Rhode Island. In view that the wast… more

Failure analysis of Ti - 15% Ta getter wire used for sublimation in the vacuum chambers of the Tandem Mirror Experiment

Description: The Tandem Mirror Experiment uses Ti-15% Ta getter wire for sublimation in the vacuum chambers in which the magnets are located. These wires have failed prematurely in service, resulting in increased costs and downtime. We have used optical metallography to show that the reason for these failures was the cycling of the material through the alpha-beta transition temperature, causing alpha-titanium precipitation at the grain boundaries, depression of the melting temperatures of those boundaries, … more

Follow-up inspection of the Formerly Utilized Sites Remedial-Action Program

Description: Corrective actions had been taken in four of the six areas of concern that were addressed in the 1982 report. The remaining two areas are summarized as follows: Certification of Remedial Actions. We found, in the initial inspection, that FUSRAP properties were not being certified as decontaminated in a timely manner following remedial action. This problem has not yet been resolved. The Assistant Secretary for Nuclear Energy acknowledged that the certification process is lengthy but maintained t… more

Generation of H/sup -/, D/sup -/ ions on composite surfaces with application to surface/plasma ion source systems

Description: We review some salient features of the experimental and theoretical data pertaining to hydrogen negative ion generation on minimum-work-function composite surfaces consisting of Cs/transition metal substrates. Cesium or hydrogen ion bombardment of a cesium-activated negatively-biased electrode exposed to a cesium-hydrogen discharge results in the release of hydrogen negative ions. These ions originate through desorbtion of hydrogen particles by incident cesium ions, desorbtion by incident hydro… more

Microwave kinoform for magnetic fusion

Description: A microwave kinoform that modifies both the phase and polarization of an incident wavefront has been designed. This kinoform for the TMX-U magnetic fusion experiment has been fabricated and tested. The design procedure, method of fabrication, and experimental test results are discussed.

Response of the Saver Dipole Beam Tube to single-phase helium pressure

Description: One Energy Saver Dipole Beam Tube (No. MB 124211) was tested under static and pulsed pressure conditions. Under static pressure, permanent deformation started at about 125 psi and reached .006 inches across flats after 220 psi exposure. Final catastrophic collapse occurred at 325 psi. Pressure pulses of shape and duration approximating the single phase helium pressure during a full house quench had no effect on the tube (previously staticly pressurized to 220 psi) up to 285 psi and a slight yie… more

The Soviets' 5-Year Plan (1981-1985)

Description: On Jan. 1, 1981 the Soviet Union's Eleventh Five Year Plan (1981-85) began. An analysis of the new plan provides some insights into Soviet priorities and economic prospects for the next half-decade. The following are the plan's main goals: to allocate sufficient investment funds to ensure adequate growth of output in the industry, agriculture, transportation, energy, and other sectors; to raise consumer income sufficiently to provide needed incentives and increase consumer satisfaction; to meet… more
