H(t Vector,t)H scattering at low energies. [Differential cross sections, vector analyzing powers, 1. 26 to 3. 71 MeV cm]

Description: Angular distributions of the differential cross section and vector analyzing power for H + t approaches elastic scattering, at center-of-mass energies 1.26, 1.68, 2.19, 2.70, 3.21, and 3.71 MeV are presented. A preliminary phase-shift analysis of the data confirms the importance of the odd-parity tensor and even-parity spin-orbit nucleon-nucleon forces in model calculations for the /sup 4/He system in this energy range.

Report of the surface science workshop

Description: A three-day workshop was held to review the various areas of energy development and technology in which surface science plays major roles and makes major contributions, and to identify the major surface-science-related problem areas in the fields with ERDA's mission in the fossil, nuclear, fusion, geothermal, and solar energy technologies and in the field of environmental control. The workshop activities are summarized. (GHT)

SPHERE: a spherical-geometry multimaterial electron/photon Monte Carlo transport code

Description: SPHERE provides experimenters and theorists with a method for the routine solution of coupled electron/photon transport through multimaterial configurations possessing spherical symmetry. Emphasis is placed upon operational simplicity without sacrificing the rigor of the model. SPHERE combines condensed-history electron Monte Carlo with conventional single-scattering photon Monte Carlo in order to describe the transport of all generations of particles from several MeV down to 1.0 and 10.0 keV f… more

Enzymatic studies of radiation damage. Progress report, July 1, 1976-September 30, 1977

Description: The major accomplishments of the year were a new method and a totally unexpected discovery that venom phosphodiesterase belongs to the group of single-strand specific nucleases. It acts on viral duplex DNA by producing a series of shorter fragments of duplex DNA. It was also found that the relaxed circular DNA of PM2 virus, that was previously enzymatically ligated, may be opened by very high amounts of phosphodiesterase. The new method deals with a simplified way of preparing polynucleotide ki… more

Production of. gamma. (9. 5) in e/sup +/e/sup -/ annihilation and photoproduction. [Cross sections]

Description: Assuming that the new resonance ..gamma..(9.5) is a vector meson, its leptonic and hadronic decay widths are calculated in analogy to those of psi(3.1). Then, using the Breit-Wigner formula, the production cross section in e/sup +/e/sup -/ annihilation is predicted. The tensor dominance of the Pomeron, together with the vector dominance model, is invoked to estimate the photoproduction cross section.

Nuclear shipping and waste disposal cost estimates

Description: Cost estimates for the shipping of spent fuel from the reactor, shipping of waste from the reprocessing plant, and disposal of reprocessing plant wastes have been made for five reactor types. The reactors considered are the light-water reactor (LWR), the mixed-oxide-fueled light-water reactor (MOX), the Canadian deuterium-uranium reactor (CANDU), the fast breeder reactor (FBR), and the high-temperature gas-cooled reactor (HTGR). In addition to the cost estimates, this report provides details on… more

Experimental investigation of the trapping and energy loss mechanisms of intense relativistic electron rings in hydrogen gas and plasma

Description: The results of an experimental study on the trapping and energy loss mechanisms of intense, relativistic electron rings confined in Astron-like magnetic field geometries are presented. The work is subdivided into four sections: gas trapping; average ring electron energetics; plasma trapping, and hollow-beam cusp-injection into gas and plasma. The mechanisms by which the injected beam coalesces into a current ring in the existing Cornell RECE-Berta facility are considered. To investigate the nat… more

HTGR fuel development: investigations of breakages of uranium-loaded weak acid resin microspheres

Description: During the HTGR fuel development program, a high percentage of uranium-loaded weak acid resin microspheres broke during pneumatic transfer, carbonization, and conversion. One batch had been loaded by the UO/sub 3/ method; the other by the ammonia neutralization method. To determine the causes of failure, samples of the two failed batches were investigated by optical microscopy, scanning electron microscopy, electron beam microprobe, and other techniques. Causes of failure are postulated and met… more

Environmental control implications of generating electric power from coal. 1977 technology status report. Appendix F. Flue gas desulfurization in the United States, 1977. [108 references]

Description: This report details the current status of flue gas desulfurization (FGD) in conventional coal-fired power plants in the U.S. Sepecifications and features are listed for all commercial FGD installations now in operation or being constructed in this country. The FGD operational experience in each plant is summarized and evaluations are made of process, equipment, and operational performance. FGD in other countries, mainly Japan and West Germany, is reviewed for applicability in the U.S. Federal a… more

Analysis of the National Energy Plan

Description: The plan is treated by end-use sectors, except for utilities and fuel prices which are presented as separate topics. First, the specific strategies and policies contained in the April 20, 1977, White House Fact Sheet and the April 29, 1977, publication entitled, The National Energy Plan (NEP) are itemized. Next, a further explanation of several of the policies is provided based on information in HR 8631, The National Energy Act. Finally, an analysis of some of the implications of the NEP is per… more

Uranium Favorability of the San Rafael Swell Area, East-Central Utah

Description: Purpose and scope: The purpose of this study was to delineate new areas favorable for uranium exploration in the San Rafael Swell region of east-central Utah. Emphasis was placed on the sandstone and siltstone members of the lower Chinle Formation (Triassic) and on the Salt Wash and Brushy Basin Members of the Morrison Formation (Jurassic). The White Rim Sandstone (Permian) was also studied, but not extensively. This project began in January 1976 and was completed in March 1977. Field work was … more
