Normal-zone detectors for the MFTF-B coils. Revision 1

Description: In order to protect a set of inductively coupled superconducting magnets, it is necessary to locate and measure normal zone voltages that are small compared with the mutual and self-induced voltages. The method described in this report uses two sets of voltage measurements to locate and measure one or more normal zones in any number of coupled coils. One set of voltages is the outputs of bridges that balance out the self-induced voltages. The other set of voltages can be the voltages across the… more

GAMIDEN: a program to aid in the identification of unknown materials by gamma-ray spectroscopy

Description: The intent of the computer code GAMIDEN is to help identify isotopes by their gamma-ray emissions and thus to assist in the nondestructive assay of unknown materials. From both radioactive decays and neutron captures, GAMIDEN searches GAMTOT83, a file of gamma-ray spectra, for matches with observed photon energies. This report describes the search procedure, outlines the use of the code, and gives an example. The code is designed to operate on the CRAY 1 computer at Lawrence Livermore National … more

Advanced uranium enrichment technologies

Description: The Advanced Gas Centrifuge and Atomic Vapor Laser Isotope Separation methods are described. The status and potential of the technologies are summarized, the programs outlined, and the economic incentives are noted. How the advanced technologies, once demonstrated, might be deployed so that SWV costs in the 1990s can be significantly reduced is described.

Engineering basis for selection of positron source material

Description: This note describes the engineering basis for the selection of the positron source material. It assumes the approximate physics parameters have already been chosen (i.e. a high Z material of 6 radiation lengths thickness). As part of this study a basic heat transfer analysis of the target was performed and is discussed. It is concluded that Ta-10W is the most likely material to meet required physics parameters and not fail structurally.

Recovery of protactinium-231 and thorium-230 from cotter concentrate: pilot plant operatins and process development

Description: The equipment and methods used to recover and purify 339 g of thorium-230 and 890 mg of protactinium-231 from 22 of the 1251 drums of Cotter Concentrate are described. The process developed was (1) dissolution at 100/sup 0/C in concentrated nitric acid and dilution to 2 to 3 molar acid, (2) filtration to remove undissolved solids (mostly silica filter aid), (3) extraction of uranium with di-sec-butyl-phenyl phophonate (DSBPP) in carbon tetrachloride, (4) extraction of both thorium and protactin… more

Human-factors engineering control-room design review/audit: Waterford 3 SES Generating Station, Louisiana Power and Light Company

Description: A human factors engineering design review/audit of the Waterford-3 control room was performed at the site on May 10 through May 13, 1982. The report was prepared on the basis of the HFEB's review of the applicant's Preliminary Human Engineering Discrepancy (PHED) report and the human factors engineering design review performed at the site. This design review was carried out by a team from the Human Factors Engineering Branch, Division of Human Factors Safety. The review team was assisted by con… more

Calculation of a tracking force

Description: The original calculation (1975-76) of an electromagnetic mechanism for beam-channel tracking is presented. The system model is not realistic because only a flat profile channel which completely encloses the beam is considered. However, a clear demonstration of the existence of a tracking force is made, as a point of departure for the more recent studies which incorporate a realistic model of the beam head and conductivity profile.

Regional trends in transmissivity and hydraulic conductivity, lower cretaceous sands, north-central Texas

Description: Depositional and structural history control the regional trends in transmissivity and hydraulic conductivity in Lower Cretaceous-age sands along the Balcones Ouachita trend in North-Central Texas. Because of scarcity of pumping tests, delineation of trends was only possible by incorporating transmissivities estimated from specific capacities. Statistical comparison of estimated and pumping-test transmissivities confirmed the validity of this approach. The resulting contour maps should be useful… more

Equipment fragility data base. Seismic Safety Margins Research Program

Description: Part of the effort of the Seismic Safety Margins Research Program (SSMRP) has been directed at generating a fragility data base for equipment used in control and safety systems in commercial nuclear power plants. Component fragility data have been compiled in various forms, depending on their content, intended use, and level of reduction. The data are stored in a relational data base on the LLNL CEC 7600 computers; this provides easy accessibility for LLNL computer users. This report describes … more

Human-factors engineering control-room design review/audit report: Byron Generating Station, Commonwealth Edison Company

Description: A human factors engineering design review/audit of the Byron Unit 1 control room was performed at the site on November 17 through November 19, 1981. This review was accomplished using the Unit 2 control room appropriately mocked-up to reflect design changes already committed to be incorporated in Unit 1. The report was prepared on the basis of the HFEB's audit of the applicant's Preliminary Design Assessment report and the human factors engineering design review performed at the site. This desi… more

Food Stamps: 1982 Legislation

Description: This report discusses legislative issues regarding food stamp appropriations. Authorization for food stamp appropriations was to have expired at the end of FY82; in addition, the FY83-85 budget resolution assumed substantial savings in food stamps. As a result, and with the potential of an FY82 food stamp funding shortfall averted by the appropriation of a $1 billion supplemental, Congress acted to reauthorize appropriations and limit program costs in the 1982 budget reconciliation process.
