Creating a word list for technical and clerical personnel

The Savannah River Plant and Laboratory employ more than 16,000 people. When the separate Publications Divisions of the Plant and Laboratory were combined it was determined that a single source of information for using terms was needed, and that the source would take the form of a word list. The Word List was issued to more than 5000 employees onsite. In addition, the Word List is being added to the site computer network as a reference document and as an online spelling checker where more than 2000 employees will have access to it through their personal computers.

Background radiation from fission pulses (open access)

Background radiation from fission pulses

Extensive source terms for beta, gamma, and neutrons following fission pulses are presented in various tabular and graphical forms. Neutron results from a wide range of fissioning nuclides (42) are examined and detailed information is provided for four fuels: /sup 235/U, /sup 238/U, /sup 232/Th, and /sup 239/Pu; these bracket the range of the delayed spectra. Results at several cooling (decay) times are presented. For ..beta../sup -/ and ..gamma.. spectra, only /sup 235/U and /sup 239/Pu results are given; fission-product data are currently inadequate for other fuels. The data base consists of all known measured data for individual fission products extensively supplemented with nuclear model results. The process is evolutionary, and therefore, the current base is summarized in sufficient detail for users to judge its quality. Comparisons with recent delayed neutron experiments and total ..beta../sup -/ and ..gamma.. decay energies are included. 27 refs., 47 figs., 9 tabs.

Project to design and develop an energy-related program: For public housing residents and renters: Volume 1, Final report (open access)

Project to design and develop an energy-related program: For public housing residents and renters: Volume 1, Final report

This demonstration project was undertaken as a result of an unsolicited proposal submitted by THE ASSIGNMENT GROUP (TAG) to the Office of Minority Economic Impact, Department of Energy (DOE). The problem to which the proposal responded was how to minimize the costs associated with public housing tenants in standard public housing as well as under homeownership transfers. A related problem was how to graduate the tenants to another level of responsibility and self-sufficiency through resident business developments and training in energy-related fields. The size and gravity of the problem necessitated a purpose or aim that had nationwide application, yet lent itself to a microscopic look. Consequently, the goal that emanated was the design and development of an energy-related demonstration program that educates public housing residents, facilitates indigenous business development where appropriate, and trains residents to provide needed services.

Laboratory work in support of West Valley glass development (open access)

Laboratory work in support of West Valley glass development

Over the past six years, Pacific Northwest Laboratory (PNL) has conducted several studies in support of waste glass composition development and testing of glass compositions suitable for immobilizing the nuclear wastes stored at West Valley, New York. As a result of pilot-scale testing conducted by PNL, the glass composition was changed from that originally recommended in response to changes in the waste stream, and several processing-related problems were discovered. These problems were solved, or sufficiently addressed to determine their likely effect on the glass melting operations to be conducted at West Valley. This report describes the development of the waste glass composition, WV-205, and discusses solutions to processing problems such as foaming and insoluble sludges, as well as other issues such as effects of feed variations on processing of the resulting glass. An evaluation of the WV-205 glass from a repository perspective is included in the appendix to this report.

Environmental surveillance at Los Alamos during 1987 (open access)

Environmental surveillance at Los Alamos during 1987

This report describes the environmental surveillance program conducted by Los Alamos National Laboratory during 1987. Routine monitoring for radiation and radioactive or chemical materials is conducted on the Laboratory site as well as in the surrounding region. Monitoring results are used to determine compliance with appropriate standards and to permit early identification of potentially undesirable trends. Results and interpretation of data for 1987 cover: external penetrating radiation; quantities of airborne emissions and liquid effluents; concentrations of chemicals and radionuclides in ambient air, surface and ground waters, municipal water supply, soils and sediments, and foodstuffs; and environmental compliance. Comparisons with appropriate standards, regulations, and background levels provide the basis for concluding that environmental effects from Laboratory operations are insignificant and do not pose a threat to the public, Laboratory employees, or the environment. 113 refs., 33 figs., 120 tabs.

Electron ray tracing programs for gun design and beam transport. [None]

Computer simulation of electron and ion sources is made by using a class of computer codes known as gun design programs. In this paper, we shall first list most of the necessary and some optional capabilities of such programs. Then we will briefly note specific codes and/or authors of codes with attention to specialized applications if any. There may be many more such programs in use than are treated here; we are only trying to cover a range of examples, not perform a comprehensive survey.

Determining cerium in plutonium by anion exchange and x-ray fluorescence (open access)

Determining cerium in plutonium by anion exchange and x-ray fluorescence

This report describes a procedure for determining cerium in plutonium using an anion-exchange separation and x-ray fluorescence. We add lanthanum to the plutonium solution as an internal standard, oxidize the plutonium to Pu/sup /plus/4/, and pass the solution through an anion-exchange column with 8M HCl. The Pu/sup /plus/4/ sorbs to the resin, and the cerium and lanthanum pass through the column completely. We evaporate the solution containing the cerium and the lanthanum to 0.5 mL for pipetting onto a resin paper disc. The Pu/sup /plus/4/ is eluted off the column using 0.1M HCl. We then measure the K/sub ..cap alpha../ x-ray line for both cerium and lanthanum. The ratio of cerium to lanthanum for the sample is then compared with those from the standards. This method has a precision of 2.8% relative standard deviation for cerium over a concentration range of 0.1 to 5% cerium. 2 refs., 2 figs., 3 tabs.

Sulfur tolerant anode materials (open access)

Sulfur tolerant anode materials

The goal of this program is the development of a molten carbonate fuel cell (MCFC) anode which is more tolerant of sulfur contaminants in the fuel than the current state-of-the-art nickel-based anode structures. This program addresses two different but related aspects of the sulfur contamination problem. The primary aspect is concerned with the development of a sulfur tolerant electrocatalyst for the fuel oxidation reaction. A secondary issue is the development of a sulfur tolerant water-gas-shift reaction catalyst and an investigation of potential steam reforming catalysts which also have some sulfur tolerant capabilities. These two aspects are being addressed as two separate tasks.

A model for electron/ion recombination in ionization chambers (open access)

A model for electron/ion recombination in ionization chambers

The recombination of free electrons and positive ions along charged particle tracks in gases has been modeled using electron tranport equations, which assume homogeneous distribution in the vicinity of the tracks. The equations include space charge terms, which have been negelected in previous models. A formula for the electron yield as a function of detector applied potential is obtained from a perturbation solution valid when the ratio of the Debye length to the charge column radius is larger then unity. When this ratio is very large, the formula reduces to that of previous models. Pulse height measurements in a /sup 3/He ionization chamber indicate 2% to 30% losses to recombination which vary with applied field, particle type, and energy. Using reasonable values for the electron transport coefficients, the calculated loss of signal to recommendation is generally in agreement with experiment, but the variation with applied bias is stronger in the experiment.

A summary of environmentally assisted crack-growth studies performed at Westinghouse Electric Corporation: Under funding from the Heavy-Section Steel Technology Program

This report was prepared as an attempt to collect the information developed in the crack-growth studies at Westinghouse from 1969 to 1986. Although progress reports were issued regularly over the entire period, the program results have not previously been integrated in a single document. The effect of a pressurized-water environment in the enhancement of fatigue crack growth at low frequencies of loading was discovered by Kondo in 1971 and verified in this program shortly thereafter. To characterize plates and forgings, as well as welds and heat-affected zones, a very large number of tests were done in the program. These tests were carried out in a series of matrices structured to investigate various issues, and the results are collected in this report. This work provided a data base for development of ASME Code reference crack-growth curves, as well as insights into some of the mechanisms of environmental enhancement. Static-load crack-growth-rate tests were conducted in the program with some specimens loaded in excess of 11 years. Static-load crack growth was observed in the heat-affected zone specimens and in one base metal heat after several years of exposure.

Two gauge boson physics at future colliders (open access)

Two gauge boson physics at future colliders

Electroweak unification suggests that there should be WW and ZZ physics analogous to {gamma}{gamma} physics. Indeed, WW and ZZ collisions will provide an opportunity to search for the Higgs boson at future high energy colliders. Cross sections in the picobarn range are predicted for Higgs boson production at the proposed 40-TeV SSC. While other states may be produced by WW and ZZ collisions, it is the Higgs boson that looms as the most attractive objective. 31 refs., 5 figs.

Low-energy structure of four-dimensional superstrings (open access)

Low-energy structure of four-dimensional superstrings

The N = 1, d = 4 supergravity theories derived as the low-energy limit of four-dimensional superstrings are discussed, focusing on the properties of their effective potentials. Gauge symmetry breaking is possible along several flat directions. A class of superpotential modifications is introduced, which describes supersymmetry breaking with vanishing cosmological constant and Str M{sup 2} = 0 at any minimum of the tree level potential. Under more restrictive assumptions, there are minima with broken supersymmetry at which also Str f(M{sup 2}) = 0 for any function f, so that the whole one-loop cosmological constant vanishes. This result is interpreted in terms of a new discrete boson-fermion symmetry, relating particles whose helicities differ by 3/2, e.g., the graviton and the dilatino.' 21 refs.

The role of biotechnology in the treatment of geothermal residual sludges (open access)

The role of biotechnology in the treatment of geothermal residual sludges

Power plants which use geothermal heat to generate electric power produce a residual sludge in large quantities. This material precipitates from supersaturated brines and contains toxic metals, some of which are present in concentrations exceeding the non hazardous waste disposal regulations. Disposal of this waste as hazardous waste is costly. Work in this laboratory has shown that a biotreatment of the geothermal waste in which toxic metal resistant acidophilic organisms are used can serve as a basis for a new biotechnology for detoxification of geothermal residual brine sludges. Phase one studies have shown that an economically and technically feasible biotechnology can be developed. The efficiency of this technology depends on a number of parameters such as the bioreactor design, residence time, and the number and concentration of toxic metals to be removed. Further, the process, while rendering a detoxified material, produces a liquid phase which is enriched in toxic metals. This aqueous phase can be reinjected into the wells, or processed for the recovery of toxic metals, some of which are commercially valuable, for example, chromium. A parallel study in this laboratory has shown that a combined chemical and biochemical process for the recovery of these metals may also be …
