The Refuge Revenue Sharing Fund (RRSF) was enacted in response to the concern of local governments regarding losses to their tax base due to the presence of federally owned land under the jurisdiction of the Fish and Wildlife Service. This report outlines recent history of RRSF payment levels. It examines the RRSF and describes how the fund differs in its treatment of reserved and acquired lands under the jurisdiction of FWS. The report also examines the Payment in Lieu of Taxes (PILT) program in detail.

In the 7-GeV Advanced Photon Source (APS) storage ring, the tapered sections are considered to be the main contributor to the transverse impedance. The large tube represents the beam chamber, and the small one the insertion device section. Both are connected by a tapered transition with angle {theta}. This note presents a power law dependence of the transverse loss factor on the taper angle for this structure.

The Pennsylvania State University is conducting a superclean coal-water slurry (SCCWS) program for the US Department of Energy (DOE) and the Commonwealth of Pennsylvania with the objective of demonstrating the capability of effectively firing SCCWS in industrial boilers designed for oil. Penn State has entered into a cooperative agreement with DOE to determine if SCCWS (a fuel containing coal with less than 3% ash and 0.9% sulfur) can effectively be burned in oil-designed industrial boilers without adverse impact on boiler rating, maintainability, reliability, and availability. The project will provide information on the design of new systems specifically configured to fire these clean coal-based fuels. The project consists of three phases: (1) design, permitting, and test planning, (2) construction and start up, and (3) operations and disposition. The boiler testing will determine if the SCCWS combustion characteristics, heat release rate, slagging and fouling factors, erosion and corrosion limits, and fuel transport, storage, and handling can be accommodated in an oil-designed boiler. In addition, the proof-of-concept demonstration will generate data to determine how the properties of SCCWS and its parent coal affect boiler performance. Economic factors associated with retrofitting and operating boilers will be identified to assess the viability of future oil-to-coal …

An isotopic heat source is formed using stacks of thin individual layers of a refractory isotopic fuel, preferably thulium oxide, alternating with layers of a low atomic weight diluent, preferably graphite. The graphite serves several functions: to act as a moderator during neutron irradiation, to minimize bremsstrahlung radiation, and to facilitate heat transfer. The fuel stacks are inserted into a heat block, which is encased in a sealed, insulated and shielded structural container. Heat pipes are inserted in the heat block and contain a working fluid. The heat pipe working fluid transfers heat from the heat block to a heat exchanger for power conversion. Single phase gas pressure controls the flow of the working fluid for maximum heat exchange and to provide passive cooling.

A report is given on progress made during the second year of a three year contract studying the feasibility of nuclear pumping the atomic iodine laser. Experimental results are presented showing efficiencies of 25--38% at converting neutron-induced nuclear reaction energy in the excimer XeBr into UV photons which can be used to pump the laser. Parametric studies were done utilizing the {sup 10}B(n,{alpha}){sup 7}Li reaction, with three bromine donor chemicals, over a range of pressures and mix ratios, to optimize the fluorescence efficiency.

The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

We have answered the PAC question ( Demonstrate the jet energy resolution of your proposed detector by studying decays Z {yields} jet + jet and Z{prime} {yields} jet + jet, M{sub Z{prime}} = 1 TeV.'') using a general program called SSCSIM. This program is a tool for investigating simple questions involving the relations between detector parameters and physics capabilities of a detector. A different package called ANLSIM developed by our colleagues at Argonne has also been used to answer this question. The results as expected are very similar. In this note we will try to document our procedures. Our tentative conclusion from this study is that physics induced effects, out-of-cone fluctuations and underlying event fluctuations, dominate the resolution. Pushing the detector performance to the limits of technology improves the effective resolution by at most 20%. 20 refs., 6 figs., 5 tabs.

The drought of 1988 caused the operations group to become concerned about the rate of evaporation from the Main Ring cooling ponds. They needed a way to data-log windspeed and direction. They had an old broken Heathkit weather station. The anemometer and windvane were salvaged and repaired. An interface to two MADC channels on the PBAR CAMAC link was built on an old piece of CAMAC card with salvaged parts. The project cost nothing. It has been in service since January 1989.

The traveler collaborated with Drs. J. L. Sarmiento and J. C. Orr of the Program in Atmospheric Sciences at Princeton University to finish the article A Perturbation Simulation of CO{sub 2} Uptake in an Ocean Circulation Model,'' which has been submitted to the Journal of Geophysical Research for publication. With F. Joos, a graduate student from the University of Bern, the traveler started writing a journal article describing a box model of the global carbon cycle that is an extension of the one-dimensional box-diffusion model. The traveler further collaborated with F. Joos and Dr. J. L. Sarmiento on modeling the potential enhancement of oceanic CO{sub 2} uptake by fertilizing the southern ocean with iron. A letter describing the results is currently being written for the journal Nature.

The effective design and operation of processes for conversion of coal to fluid fuels requires accurate knowledge of the phase behavior of the fluid mixtures encountered in the conversion process. Multiple phases are present in essentially all stages of feed preparation, conversion reactions and product separation; thus, knowledge of the behavior of these multiple phases is important in each step. The overall objective of the author's work is to develop accurate predictive methods for representation of vapor-liquid equilibria in systems encountered in coal conversion processes. 59 refs., 6 figs., 7 tabs.

Superplastic forming of Ti-6Al-4V was investigated with three heats of material to examine the effects of extrinsic and intrinsic variables on strain rate sensitivity and flow stress. Tension tests with strain rate jumps and step strain rate tests were used to determine the effects of strain rate, strain, and temperature on strain rate sensitivity of Ti-6Al-4V. Superplastic forming of Ti-6Al-4V is strongly influenced by deformation temperature. The uniform elongation and the strain rate sensitivity were maximized at 900{degree}C in the temperature range tested. In the strain rate range tested, strain rate sensitivity increased slightly as the strain rate decreased. In examining the results, it was apparent that at high strains, grain growth decreased strain rate sensitivity. This decrease was a strong function of temperature, which minimized at 875{degree}C. The strong dependence of superplastic behavior on temperature can be related to relative amounts of alpha and beta in the microstructure, as shown in the model for superplastic deformation of Ti-6Al-4V.

The traveler participated in an International Symposium on Trends in Biological Dosimetry and presented an invited paper entitled, Adducts in sperm protamine and DNA vs mutation frequency.'' The purpose of the Symposium was to examine the applicability of new methods to study quantitatively the effects of xenobiotic agents (radiation and chemicals) on molecular, cellular and organ systems, with special emphasis on human biological dosimetry. The general areas covered at the meeting included studies on parent compounds and metabolites; protein adducts; DNA adducts; gene mutations; cytogenetic end-points and reproductive methods.

Research continued on coal combustion. The project objectives are (1) to measure the effect of devolatilization temperature and time on the properties of the char and (2) characterize and quantify the effect of thermal annealing on char reactivity during char burnout under conditions of pulverized combustion. Work done during this reporting period includes: coal devolatilization/char generation; char oxidation in the thermogravimetric analyzer (TGA). Oxidation was conducted at 500{degree}C in a 5% O{sub 2}-N{sub 2} mixture at 150 cm{sup 3}/min flowrate. Under these conditions external and intraparticle diffusional limitations were negligible. Three chars obtained from the Pittsburgh No. 8 coal were used in the experiments; oxidation of single char particles in the electrodynamic balance. Experiments were carried out with particles from the Pittsburgh No. 8 char and a spherocarb'' synthetic char obtained from a vendor. The spherocarb char was used because the particles are nearly spherical thus avoiding the complications of irregular particle shape. 15 figs., 1 tab.

To forecast the ecological impact of global change, research initiatives are needed on the explicit role of humans in ecological systems, and on how ecological processes functioning at different spatial and temporal scales are coupled. Furthermore, to synthesize the results of ecological research for Congress, policymakers, and the general public, a new agency, called the United States Ecological Survey (USES) is urgently required. Also, a national commitment to environmental health, as exemplified by establishing a National Institutes of the Environment (NIE), should be a goal.

We have recently been trying to accumulate all of the information necessary to decide on the layout of the regular curved arcs of the Low Energy Ring (LER) and there have been several ABC Notes published on different aspects of the problem. This note will describe the layout that has been derived from these considerations.
