D/sup -/ production by multiple charge-transfer collisions of low-energy D ions and atoms in cesium vapor

Description: The production of D/sup -/ by multiple charge-transfer collisions of a D/sup +/ beam in a cesium-vapor target is considered for D/sup +/ energies above 300 eV. The cross sections relevant to D/sup -/ formation are obtained by a least-squares fit of three-charge-state differential equations to experimental yield curves. Implications for production of intense negative-ion beams are discussed, and speculations are made about extrapolation to lower engeries.

Enhancing the use of coals by gas reburning-sorbent injection

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on three coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices; tangential, wall, and cyclone fired. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x} emissions, by a combination of two developed tech… more

Diamond-turning tool setting by interferogram analysis

Description: A method was developed to establish a numerically controlled tool path with respect to the work spindle centerline. Particularly adapted to the diamond turning of optics, this method is based upon interferogram analysis and is applicable to the establishment of the work spindle centerline relative to the tool path for any center-turned optic having a well-defined vertex radius of curvature. The application reported is for an f/2 concave spherical mirror.

Arsenic Removal From Gaseous Streams

Description: Uranium feed materials, depending on the production process, have been found to contain arsenic (As) as a contaminant. Analyses show the As to be present as As pentafluoride (AsF{sub 5}) and/or hexafluoroarsenic acid (HAsF{sub 6}) and enter the enrichment cycle through contaminated hydrogen fluoride (HF). Problems related to corrosion of cylinder valves and plugging of feed lines and valves have been attributed to the As. Techniques to separate AsF{sub 5} from uranium hexafluoride (UF{sub 6}) u… more

Development of a three-dimensional model of the atmospheric boundary layer using the finite element method

Description: This report summarizes our current effort and ideas toward the development of a model for the planetary boundary layer using the finite element technique. As an initial step, the finite element methodology is applied to simpler version of the boundary layer equations given by the two-dimensional, constant-property, incompressible conservation equations (Navier-Stokes equations). Solution procedures for both the steady-state and transient equations are discussed. For the transient problem, a var… more

Numerical solution of the Schroedinger integral equation for dt. mu. Progress report

Description: The Schroedinger Integral Equation is derived for an N-body system, and solutions for required Green's functions are obtained. The initial method of numerical solution has yielded the correct ground states and lower excited states of He (test case) and dt..mu... Steps are being taken to improve the numerical accuracy.

Radioactivity in gaseous waste discharged from the separations facilities during fourth quarter of 1979

Description: This document is issued quarterly for the purpose of summarizing the radioactive gaseous wastes that are discharged from the facilities of the Rockwell Hanford Operations (Rockwell). Data on alpha and beta emissions during 1979 are presented where relevant to the gaseous effluent. Emission data are not included on gaseous wastes produced within the 200 areas by other Hanford contractors.

Analysis of the role of an interfacility SNM accounting system

Description: Lawrence Livermore National Laboratory (LLNL) undertook the task of analyzing the actual and potential value of an interfacility NRC material accounting system in deterring and detecting both material diversion and facility material accounting data falsification. The most important conclusion is that only relatively minor changes are needed to upgrade the current NRC interfacility reporting system. The emphasis of the task was on evaluating the usefulness of an NRC-monitored material accounting… more

Proposal to utilize fusion reactor energy sources for chemical process applications

Description: We propose to study the utilization of high-temperature (approximately 2000-2500K) process heat from fusion reactors for large-scale chemical process applications. Of particular interest is the decomposition reaction, CO/sub 2/ ..-->.. CO + /sup 1///sub 2/O/sub 2/, which at 2500K should yield approximately 60 percent conversion to CO if O/sub 2/ is partially removed through an oxide membrane. Hydrogen can be derived from CO at lower temperatures by reacting CO with steam, and C can also be d… more

Polarizer reflectivity variations

Description: On Shiva the beam energy along the chain is monitored using available reflections and/or transmission through beam steering, splitting, and polarizing optics without the intrusion of any additional glass for diagnostics. On the preamp table the diagnostic signal is obtained from the signal transmitted through turning mirrors. At the input of each chain the signal is obtained from the transmission through one of the mirrors used for the chain input alignment sensor (CHIP). At the chain output th… more

Inclusive large mass muon pair production in ultra-relativistic nucleus-nucleus collisions for colliding beams

Description: For colliding beams of several species of ions we compare thermal to perturbative quantum chromodynamic contributions for inclusive large mass muon pair production by using a hydrodynamic model to estimate the temperatures of the quark-gluon plasma produced by each species. The production of high energy dimuons with M {approx equal}-4 GeV, will be favored energetically by the quark-gluon plasma. 10 refs., 4 figs., 2 tabs.

Expiring Unemployment Insurance Provisions

Description: This report discusses several key provisions related to extended federal unemployment benefits that are temporary and, therefore, scheduled to expire. This report describes the consequences of these expirations for the financing and availability of unemployment benefits in states. It also summarizes the last three laws that have extended these expiring provisions: P.L. 112-240, P.L. 112-96, and P.L. 112-78.
