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 limestone is added in a staged burner, there is a strong possibility that under certain circumstances CaS is produced in the reducing (fuel-rich) zone of the burner. Since CaS is more stable than CaSO/sub 4/, this affords the opportunity to (1) operate the burner at a higher temperature, 2200 to 2500 F, (2) pass the CaS rapidly through the high temperature zone (before dissociation), and (3) complete the combustion in a lean (air-rich) region where the sulfur is finally retained in CaSO/sub 4/. For these reasons this program has concentrated on the high temperature chemistry and kinetics of CaS. To achieve the program objective, the program was divided into three tasks. These involved (1) a study of CaS formation, (2) a …

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.

This report addresses the comments on a previous note about intrabeam scattering calculation for bunched beams in colliding mode.

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-tank sludge processing batch.

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 waste resulted from the processing of scrap materials generated in DOE Defense Programs activities and due to the lack of adequate capacity at commercial waste disposal facilities, DOE agreed to accept the waste for burial at the Y-12 Plant. Site characterization and well monitoring results are presented of the disposal site.

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, and the subsequent melting of those boundaries in areas where the wires had achieved localized higher temperatures.

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 that progress was being made. The Assistant Secretary stated that attempts will be made to speed up the process; and Permanent Waste Disposal. The lack of permanent repositories for FUSRAP wastes continues to be a major issue. The Assistant Secretary for Nuclear Energy indicated to us that meetings are being held with state and congressional representatives to impress on them the need for locating disposal sites for FUSRAP wastes in their states.

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 hydrogen ions, and by backscattering of incident hydrogen. Each process is characterized by a specific energy and angular distribution. The calculation of ion formation in the crystal selvage region is discussed for different approximations to the surface potential. An ab initio, all-electron, local density functional model for the composite surface electronics is discussed.

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.

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 yield effect at 305 psi. Repeated pulses at 305 psi appeared to cause little or no further yielding. When compared to static pressure effects the 305 psi pulse produced the same deflection as about 235 psi static pressure.

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 security needs at home and abroad; and to import technology, grain and other goods needed to meet priority domestic goals.

A description of the FEL experiment underway at the 10 kA, 5 MeV Experimental Test Accelerator (ETA) is described. The facility has been designed to investigate the high-gain operation of an FEL.
